I'm trying to run my Laravel 5.7 app but will always get the error Could not find driver when trying to run a query in my page.
Here's portion of my .env code:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
Anyway instead of using mysql, we use MariaDB instead. I can confirm that mariadb is running without any problem because if I run mysql -u root -p in my terminal, I can connect to my MariaDB. Here's what my welcome message will be upon successfully log into my MariaDB.
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 44
Server version: 10.2.8-MariaDB MariaDB Server
Running phpinfo() will return this:
PDO support enabled
PDO drivers pgsql, sqlite
MySQL driver for PDO George Schlossnagle, Wez Furlong, Ilia Alshanetsky, Johannes Schlueter
MySQLi Zak Greant, Georg Richter, Andrey Hristov, Ulf Wendel
MySQLnd Andrey Hristov, Ulf Wendel, Georg Richter, Johannes Schlüter
But I can confirm my /opt/rh/rh-php71/root/usr/lib64/php/modules folder contains pdo_mysql.so, pdo.so,mysqli.so and mysqlnd.so
And also my /etc/opt/rh/rh-php71/php.d folder contains 30-pdo_mysql.ini on which it contains just one line, extension=pdo_mysql.so
So why isn't my pdo mysql running?
It turns out I need to restart my php-fpm. Upon googling and googling, I still can't find the exact name of my php-fpm service, so I did sudo find | grep fpm and found out that my php-fpm service name is rh-php71-php-fpm
So I run sudo service rh-php71-php-fpm restart and sudo systemctl restart httpd and now mysql is listed under PDO drivers, and I can run my apps successfully.
Seriously, why did different versions of Linux have different names of the same thing?
You can install php mysql connection package from yum
At first install #yum install epel-release -y then
yum install php-mysqlnd -y

I have been successfully installing and using MySQL V5.7 in Google Colab (with Ubuntu 18.04) for quite some time. However trying to install MySQL V8 has repeated failed. I have used the following sequence of commands ..
!apt update
!apt upgrade
#!wget -c https://dev.mysql.com/get/mysql-apt-config_0.8.11-1_all.deb
!wget https://dev.mysql.com/get/mysql-apt-config_0.8.22-1_all.deb
!dpkg -i mysql-apt-config_0.8.*
!sudo apt update
!sudo apt install mysql-server
During the install, I provide the root password and have used both the strong password option as well as the legacy authentication. Everything goes fine upto this point and even the following command
!mysqld --version
returns the correct version
/usr/sbin/mysqld Ver 8.0.28 for Linux on x86_64 (MySQL Community Server - GPL)
After this things go wrong! The MySQL service should have started but it hasn't
!mysql -uroot -p
Enter password:
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' (2)
and when I try to start it, it is not recognised ( neither mysql nor mysqld)
!sudo service mysqld start
mysqld: unrecognized service
in fact, even this fails
!systemctl status mysql
System has not been booted with systemd as init system (PID 1). Can't operate.
What am I doing wrong? or what else should I do? or is it that for some reason, Google Colab with Ubuntu 18.04 does not support MySQL V8
No action required ... just this will do
!apt update > null
!apt -y install mysql-server -V
!/etc/init.d/mysql restart
then check
!mysql --version
mysql Ver 8.0.31-0ubuntu0.20.04.2 for Linux on x86_64 ((Ubuntu))
earlier this used to show Ver 5.7!
Now, with this we can now use CTE, recursion and Windows functions of v8
Check with sudo service mysql start or sudo start mysql once.
Another thing is that google colab instance might not use the system init system at all. That's why it's resulting in System has not been booted with systemd as init system. Check with the sys-v init system once. Its commands look like service service_name start. The same thing happens when trying to start services in WSL.
I need a specific version of MySQL (5.7) to be installed on my MacBook with M1.
I'm trying to do that with Homebrew.
brew install mysql#5.7
The output:
We've installed your MySQL database without a root password. To secure it run:
mysql_secure_installation
MySQL is configured to only allow connections from localhost by default
To connect run:
mysql -uroot
mysql#5.7 is keg-only, which means it was not symlinked into /opt/homebrew, because this is an alternate version of another formula.
If you need to have mysql#5.7 first in your PATH, run: echo 'export PATH="/opt/homebrew/opt/mysql#5.7/bin:$PATH"' >> ~/.zshrc
For compilers to find mysql#5.7 you may need to set: export LDFLAGS="-L/opt/homebrew/opt/mysql#5.7/lib" export CPPFLAGS="-I/opt/homebrew/opt/mysql#5.7/include"
To have launchd start mysql#5.7 now and restart at login: brew services start mysql#5.7 Or, if you don't want/need a background service you can just run: /opt/homebrew/opt/mysql#5.7/bin/mysql.server start
Right after that, I try to run:
echo 'export PATH="/opt/homebrew/opt/mysql#5.7/bin:$PATH"' >> ~/.zshrc
source .zshrc
mysql_secure_installation
And get the error:
Securing the MySQL server deployment.
Enter password for user root:
Error: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
Also, I've tried:
brew services start mysql#5.7
And also get the error:
Error: Permission denied # rb_sysopen - /Users/vivanc/Library/LaunchAgents/homebrew.mxcl.mysql#5.7.plist
Seems like there is a permissions-related problem.
Any advice is appreciated.
If you are running into issues like "Can't connect to local MySQL server through socket '/tmp/mysql.sock'" or "The post-install step did not complete successfully MySQL", and you installed a previous version of mysql (e.g. 8.x) previously, you may have been at the point where you need to clean everything before reinstalling your preferred version of mysql#x.x.
If you've already visited these to links:
Uninstall all those broken versions of MySQL and re-install it with Brew on Mac Mavericks (Coderwall) + Install MySQL 5.7 on macOS using Homebrew (github) and your're still having trouble with starting your mysql-service, you should try to also remove also /opt/homebrew/etc/my.cnf file.
Remove it together with all the related files too! Summary for an M1 Apple Silcion machine, after uninstalling via brew uninstall mysql or brew uninstall mysql#x.x, please remove:
/opt/homebrew/var/mysql
/opt/homebrew/etc/my.cnf
After this, everything worked like a fresh install (for me). Hope this saved someone's time.
While this question is specific to Apple Silicon and mysql 5.7, and I will address that in this answer, I would like to start by adding some general notes to save others time:
Homebrew supports mysql 5.7 for both intel and apple silicon.
https://formulae.brew.sh/formula/mysql#5.7
Homebrew supports mysql 5.6 for the intel chip, but not apple silicon:
https://formulae.brew.sh/formula/mysql#5.6
If you need 5.6 on apple silicon, it's probably a good idea to just settle with 5.7 since production will need to be upgraded eventually and the differences aren't that big.
In my situation I originally did brew install mysql and it gave me the latest mysql (currently 8.0). When I tried going back over it and doing brew install mysql#5.6, of course this didn't work due to not being supported on the m1 max (apple silicon). I ran into issues then trying to get brew install mysql#5.7 working. I followed some guides mentioning various suggestions. After playing with it for a while, it seems that running two versions of mysql at once will corrupt your mysql files and make it hard to work with and confuse homebrew.
I came across these guides:
brew install mysql on macOS
https://coderwall.com/p/os6woq/uninstall-all-those-broken-versions-of-mysql-and-re-install-it-with-brew-on-mac-mavericks
https://www.codegrepper.com/code-examples/shell/brew+uninstall+mysql
Before reading further, note that in my situation, I had a zip available for my whole local mysql database needs and could risk destroying what I have.
Warning! Reading further and executing these commands carelessly may delete your mysql storage. Make sure you have a backup.
brew remove mysql is a good command that got rid of my latest install.
I also needed brew remove mysql#5.7 even though this is the version I'm trying to install, but they were stepping on each other's foot...
brew cleanup is nice, I noticed it freed up some lock files.
I don't recall having any luck with:
launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
but you can try it.
rm ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist has worked for me.
But note there will also be another file in there for your 5.7 setup.
I'd recommend:
cd ~/Library/LaunchAgents/ then look around to see if you have any mysql* in there. Then if you do, such as homebrew.mxcl.mysql#5.7.plist, then remove it.
These are some that worked for me:
sudo rm -rf /usr/local/var/mysql
rm /usr/local/etc/my.cnf
rm /usr/local/etc/my.cnf.default
Also:
cd opt/homebrew/var
Then if you notice a mysql directory in there, remove it.
It's possible you might have docker or something else similar also running mysql or mysqld.
ps -ax | grep "[m]ysql"
(Note the brackets and quotes in the above is to prevent the grep from showing up in the process list and matching itself unlike the lazier version: ps -ax | grep mysql which will give the impression there's an extra mysql process running)
Once you're ready, please run:
brew services list
double-check you don't have mysql in there.
Then double check you don't have any mysql process running:
ps -ax | grep "[m]ysql"
This can happen for example if you enter mysqld for example....
You might need to do brew services stop mysql or brew services stop mysql#5.7 or similar and repeat steps if you see anything on the service list or process list.
Finally, you should be ready for a fresh install.
The fresh installation process should be rather straight forward:
brew install mysql#5.7
brew link --force mysql#5.7
brew services start mysql#5.7
Then run brew services list to make sure your installation worked correctly.
If you see it's green and "started", your installation was successful!
You should also run:
mysql_secure_installation
Then choose a password for root and go through the list of questions like validation, etc.
Once you're installed, you might also run into mysql mode issues.
cd /opt/homebrew/etc and you should find a my.cnf file.
Edit it using either vim or nano.
You should see something like:
# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from localhost
bind-address = 127.0.0.1
Edit it and set the mysql mode. For example, I don't want the no_zero_in_date mode, so I use:
# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from localhost
bind-address = 127.0.0.1
sql-mode="ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
Then restart mysql like so:
brew services restart mysql#5.7
Then double check you still have a green status "started":
brew services list
If you do, then you should have the no_zero_in_date mode disabled.
You can test it with a query:
SELECT ##sql_mode;
You should now have mysql 5.7 running on Apple Silicon and have the sql_mode set.
If you run into more troubleshooting, do your best to get into a known state such as uninstalled, doing a fresh install, or already installed with some version, etc.
I solved it after hours of searching, it was because I had not cleaned everything regarding my previous MySQL 8.X installation. I followed this and got suspicious when I realized I don't have most of the folders there. I then did a search for all folders named mysql on my computer and found a mysql folder in opt/homebrew/var. After removing it, reinstalling MySQL 5.7, and starting the server everything is working as expected.
When setting up my Apple M1 Macbook Pro I was experiencing the issue of the following error message being thrown:
Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)
My fix was to modify the MySQL config file:
nano /usr/local/etc/my.cnf
Append the following lines:
tmpdir=/tmp
user=root
Then run:
brew services restart mysql#5.7
This fixed my issue, and I was then able to connect successfully with my DB client.
Seems like I found the solution (or workaround).
After installing the MySQL 5.7 with Homebrew just run:
mysql.server start
MySQL is started and then you are able to run mysql_secure_installation and mysql commands.
I got this warning:
You should change the ownership of these directories to your user.
sudo chown -R $(whoami) /usr/local/share/doc /usr/local/share/man /usr/local/share/man/man1
And make sure that your user has write permission.
chmod u+w /usr/local/share/doc /usr/local/share/man /usr/local/share/man/man1
I run those two command then it works.
I want to install the MySQL client for the command line, not a GUI. I have searched over the web but only found instructions on installing the MySQL server.
install MySQLWorkbench, then
export PATH=$PATH:/Applications/MySQLWorkbench.app/Contents/MacOS
This strictly installs a command line client, without the other overhead:
Install Homebrew (if you don't have it):
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Then, install mysql-client:
brew install mysql-client
Then, add the mysql-client binary directory to your PATH:
echo 'export PATH="/usr/local/opt/mysql-client/bin:$PATH"' >> ~/.bash_profile
Finally, reload your bash profile:
source ~/.bash_profile
Then you should be able to run mysql in a terminal, if not try opening a new terminal
If you have already installed MySQL from the disk image (dmg) from http://dev.mysql.com/downloads/), open a terminal, run:
echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile
then, reload .bash_profile by running following command:
. ~/.bash_profile
You can now use mysql to connect to any mysql server:
mysql -h xxx.xxx.xxx.xxx -u username -p

Best option is:
brew install mysql
Mysql has a client-only set of utilities:
Mysql client shell
https://dev.mysql.com/downloads/shell/
Other command line utilities
https://dev.mysql.com/downloads/utilities/
Mac OSX version available.
There is now a mysql-client formula.
brew install mysql-client
For installing mysql-shell with homebrew, run
brew cask install mysql-shell
you can then launch the mysql shell with
mysqlsh
if you want to enter SQL mode directly, run
mysqlsh --sql
Open the "MySQL Workbench" DMG file and
# Adjust the path to the version of MySQL Workbench you downloaded
cp "/Volumes/MySQL Workbench 6.3.9.CE/MySQLWorkbench.app/Contents/MacOS/mysql" /usr/local/bin
# Make sure it's executable
chmod +x /usr/local/bin/mysql
Eject the DMG disk
Installation command from brew:
$ brew cask install mysql-shell
Look at what you can do:
$ mysqlsh --help
Run query from mysqlsh client installed:
$ mysqlsh --host=192.x.x.x --port=3306 --user=user --password=xxxxx

If you installed from the DMG on a mac, it created a mysql client but did not put it in your user path.
Add this to your .bash_profile:
export PATH="/usr/local/mysql/bin:$PATH
This will let you run mysql from anywhere as you.
As stated by the earlier answer you can get both mysql server and client libs by running
brew install mysql.
There is also client only installation. To install only client libraries run
brew install mysql-connector-c
In order to run these commands, you need homebrew package manager in your mac. You can install it by running
/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Using MacPorts you can install the client with:
sudo port install mysql57
You also need to select the installed version as your mysql
sudo port select mysql mysql57
The server is only installed if you append -server to the package name (e.g. mysql57-server)
The easiest way would be to install mysql server or workbench, copy the mysql client somewhere, update your path settings and then delete whatever you installed to get the executable in the first place.
The mysql client is available in macOS ports. If you don't have this excellent third party package manager already installed, it is available from here: https://www.macports.org/
Once you have installed macports, open a terminal and make sure everything is up to date:
sudo port selfupdate
There are multiple different versions of MySQL and mariadb (community fork of MySQL) available in the ports repos. List available versions using the following command:
port search 'mariadb*'
I recommend choosing mariadb over mysql as it is, mostly, a drop in replacement (https://mariadb.com/kb/en/mariadb-vs-mysql-compatibility/) and has excellent community support.
If applicable, choose which version of mariadb you want (a list of versions of mariadb is available here: https://downloads.mariadb.org/mariadb/+releases/). If you're not bothered, install the default version:
sudo port install mariadb
Mariadb (including the mysql-compatible command line client) is now available on your system. On my system, the CLI client resides in the following location:
$ /opt/local/bin/mysql --version
/opt/local/bin/mysql Ver 15.1 Distrib 5.5.68-MariaDB, for osx10.15 (x86_64) using readline 5.1
It's obviously a bit inconvenient to type out the full path, /opt/local/bin/mysql each time you want to use the client. Ports has already thought of this problem. To view available versions of mysql on your system, run:
$ port select mysql
Available versions for mysql:
mariadb (active)
none
Choose one from the list. For example, to use mariadb as the default mysql client:
sudo port select mysql mariadb
Now open a fresh terminal window and you should be able to start the mariadb mysql CLI client:
mysql -h <hostname> -u <username> -p
if you need a lighter solution i recommend mysql-shell, install using the command below.
brew cask install mysql-shell
To start after installation type mysqlsh.
I am setting up Nginx+PHP+MYSQL on Ubuntu 12.04.
I used
apt-get install php5-mysql
to install MySql module for PHP. However, everything seems to be installed and enabled, it is yet shown in phpinfo.php and I cant get the php application to connect to the MySql server. The php app is accessible, and I can view things on phpinfo.php.
BTW, mysql is running normally, because I am running an Rails app using it, so I know it is working fine.
As #vstm said a quick summary to help others get the answer quicker:
1. Kill php-cgi
killall php-cgi
2. Restart php-fpm
/etc/init.d/php5-fpm restart OR service php5-fpm restart
3. Double check with
grep -E 'extension=(pdo_)?mysql.so' -r /etc/php5
I have previously installed, connected and uploaded to a WordPress MySQL database via SSH no problem. The people who run my server made a few configuration changes, and now I get a "bash: mysql: command not found" error when I try to log into MySQL via the command line on the same server to access the same database.
I am relatively new to all of this, so I am really not sure what to do. When I run "which mysql" I get a message that says there is no MySQL executable in the /usr/bin directories. I can verify that MySQL is running between the fact that my site is still live and functioning and when I ran a command to test MySQL, I got a message that said "MySQL works!"
I find MySQL files in several directories, but I'm not really sure what I am looking for and how I connect to it when I do find it. I am also not sure if this is user error, or if somehow someone moved or hid MySQL from me -- likely user error??
A MySQL server is not a MySQL client.
Check if MySQL is running by executing this command:
ps aux | grep mysql | grep -v grep
And install the MySQL client:
sudo apt-get install mysql-client # Or your distribution command
If you have MySQL server up and running on your server, it does not mean you have a MySQL client installed on this server.
Try
ls -l /usr/bin/mysql*
Do you see MySQL binaries exactly present on system?
One more problem: Linux has very strange behaviour when you run binaries for another architecture.
For example, if you run a 32-bit executable on 64-bit system you will get an error message like "command or file not found", even if the binaries are actually present!
Now mysql-client has changed to default-mysql-client.
Hence the command:
sudo apt-get install default-mysql-client
Although MySQL is running, if you are not able to connect to the server using the mysql command, then you might be missing to provide soft links:
sudo ln -s /usr/local/mysql/bin/mysqladmin /usr/bin
sudo ln -s /usr/local/mysql/bin/mysql /usr/bin
This should enable you to connect.
In order to get MySQL CLI working or to access the mysql command from anywhere, there are a set of steps to be done to add it to the $PATH variable.
First, open a terminal, and run the following command
echo 'export PATH=/usr/local/mysql/bin:$PATH' >> ~/.bash_profile
Then to reload the Bash profile, run
. ~/.bash_profile
Now run,
mysql -u root -p
Enter the password which you gave during installation. You should see the following result:
Welcome to the MySQL monitor. Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 8.0.23 MySQL Community Server - GPL
You sometimes need to install MySQL on the local machine as well. That means, if you have a host running a MySQL Docker container, the strange thing happened to me that I needed to install mysql-server on the host as well, not only in the container.
The reason was that there was a shell script that needed to check the right database name from a query. In your case, it might be something different. On your host machine (which might even be your local computer, depending the your setup), if on Linux, try:
sudo apt-get update && sudo apt-get install mysql-server
Then you will get rid of
/home/.../some_bash_script.sh: line 123: mysql: command not found
