Error message when trying to open newly downloaded mySQL - mysql

I am running MacOS High Sierra version 10.13.2 on a MacBook Air (mid 2011).
I am trying to set up a local development environment through the command-line and I have already gone through some steps to the following point:
After downloading mySQL, I am and trying to initialize it through the command line for my localhost. I went then through the commands:
sudo mkdir /var/mysql
Followed by
sudo ln -s /tmp/mysql.sock /var/mysql/mysql.sock
Then went to my system preferences to start mySQL but I am encountering this error message and mySQL is not opening as a result: "Could not load MySQL preference pane."
Any help around this would be much appreciated friends! Thanks in advance.

An easier way to install (certain) apps in MacOS is to use Homebrew. There is a full step-by-step guide available here. A short version:
Install Homebrew: /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
Install MySQL: brew install mysql
Install services: brew tap homebrew/services
Set MySQL to autostart: brew services start mysql

Error with M1 Native Installation of MySQL with Homebrew

I just got my first MacOS system with an M1 chip and I'm having trouble installing the native M1 version of MySQL using Homebrew. I have my terminal configured without Rosetta and I'm using the command "brew install MySQL" but I get this error:
ritvikbiswas#Ritviks-MacBook-Pro ~ % brew install mysql
Error: Cannot install in Homebrew on ARM processor in Intel default prefix (/usr/local)!
Please create a new installation in /opt/homebrew using one of the
"Alternative Installs" from:
https://docs.brew.sh/Installation
You can migrate your previously installed formula list with:
brew bundle dump
ritvikbiswas#Ritviks-MacBook-Pro ~ %
Could anyone help me figure out why I'm getting this error? Maybe I messed up the brew installation somewhere?
You installed Homebrew into the wrong place. On x86 Mac, Homebrew uses /usr/local. On M1 Mac, Homebrew uses /opt/homebrew. I don't know where you copied and pasted the installation script. You obviously made a wrong installation.
Please go the official installation guide page. And
Uninstall your current homebrew
Reinstall homebrew back correctly following the guide.
First, uninstall (if you have wrongly installed it).
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/uninstall.sh)"
Install:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
After successful installation, you can get this message in terminal
Run these three commands in your terminal to add Homebrew to your PATH:
echo '# Set PATH, MANPATH, etc., for Homebrew.' >> /Users/userName/.zprofile
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/userName/.zprofile
eval "$(/opt/homebrew/bin/brew shellenv)"
Then set the homebrew to the right path
echo "export PATH=/opt/homebrew/bin:$PATH" >> ~/.zshrc

How to install and start MySQL 5.7 on macOS BigSur (Apple Silicon) with Homebrew?

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.

Problems installing MySQL 5.7 properly on fresh CentOS 7 install

I admit that I am new to back-end work in general and I seem to be stuck (for several hours) following through with completing the setting up process for Magento 2.3
I was following https://devdocs.magento.com/guides/v2.3/install-gde/prereq/mysql.html for my commands but to no success.
I managed to get the following installed:
Cent OS 7 (x86_64)
Apache 2.4.6
PHP 7.2.14 (all the extensions installed passed the Setup Wizard readiness check)
I used these commands to install MySQL 5.7 Community Release: (from the documentation)
wget http://dev.mysql.com/get/mysql57-community-release-el7-7.noarch.rpm
yum -y install mysql mysql-server
yum -y install mysql-community-server
To check if my installation went well, when I run:
mysql --version
I received an error message saying:
-bash: /usr/bin/mysql: No such file or directory
I know that there is something I definitely am missing out completely. When I try to start the MySQL service using the command:
systemctl start mysqld
I get the resulting error message:
Failed to start mysqld.service: Unit not found.
Any suggestions will much be appreciated. Thank you in advance.
Maybe it installed it as mariadb?
systemctl start mariadb
After removing MySQL 5.7 community release from my Cent OS, I decided to install MariaDB.
Inside the directory /etc/yum.repos.d/ I've created a file called MariaDB.repo and added this into the file:
# MariaDB 10.3 CentOS repository list - created 2019-01-25 05:36 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
I then performed the command in my terminal window:
sudo yum install MariaDB-server MariaDB-client
Because of this, mysql --version and systemctl start mysql works like a charm. Thanks #greenberet123 and #danblack for the suggestion.

Installing MySql 5.5.31 on Mac OSX 10.9?

I'm attempting to install a previous version of MySql (5.5.31) on my Mac OSX device running 10.9 Mavericks. I have been told this is possible, however, I cannot seem to locate a download for 5.5.31 Mac OSX.
I have a later version (5.6.19) installed, and I tried:
brew switch mysql 5.5.31
but I keep getting the error message:
"Error: mysql not found in the Cellar."
And I know this is because there's no 5.5.31 MySql file for it to switch to.
Anyone do this on their Mac?
Thanks
This is an old question, but I stumbled upon it through Google, so here's to anyone to stumbles upon it later.
I was trying to install MySQL 5.5 on OS X 10.10 through Homebrew.
First, you have to add homebrew/versions to your taps with:
$ homebrew tap homebrew/versions
Second, install MySQL 5.5 with:
$ homebrew install mysql55
if that doesn't work, try:
$ homebrew install homebrew/versions/mysql55
After that has successfully installed, you will get the message:
...A "/etc/my.cnf" from another install may interfere with a
Homebrew-built server starting up correctly.
To connect:
mysql -uroot
To load mysql55:
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql55.plist Or, if you don't want/need launchctl, you can just run:
mysql.server start ❯ cd /usr/local/Cellar/mys
Try mysql.server start, if that doesn't work you need to update your $PATH. In my case I added /usr/local/Cellar/mysql55/5.5.40/bin to my $PATH in my .zshrc. You can find the location of your installation by using:
$ homebrew info mysql55
After that it should work after you've added that directory to your .zshrc/.bashrc/.bash_profile etc.

Getting MySQL working on OSX 10.7 Lion

I'm currently trying to get MySQL working on OSX 10.7 Lion. I tried the brew way:
brew install mysql
-> cmake -> no problems
-> make -> no problems
-> make install -> no problems
-> done
unset TMPDIR
mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp
Installing MySQL system tables...
/usr/local/bin/mysql_install_db: line 428: 15397 Done { echo "use mysql;"; cat $create_system_tables $fill_system_tables; }
15398 Done(141) | eval "$filter_cmd_line"
15401 Segmentation fault: 11 | $mysqld_install_cmd_line > /dev/null
Installation of system tables failed! Examine the logs in
/usr/local/var/mysql for more information.
Did anyone get mysql to run on Lion?
You can download a MySQL installer as a DMG file, complete with an installer, system preferences pane and a startup script directly from MySQL. Go to MySQL's community server download page, select Mac OS X as the platform and pick the DMG file.
You can skip the registration form (there a little link under the signup form) and you should be on your way.
Once the file is downloaded, double-click on the DMG, launch the installer and complete the installation. After that, install the startup script using its installer and finally the preferences pane by double-clicking on it. I highly recommend choosing to install it for all users on the computer.
You'll find this way much easier than compiling from source.
You should check out Sequel Pro if you need a great OS X tool to manage your MySQL databases.
A drop in replacement for mysql is mariadb. You can install with 'brew install mariadb'. It builds on Lion.
Existing mysql drivers and clients just work. I'm using it with python-mysql and django.
It's even called mysql so you won't even know the difference.
Ha! Got it!
First... download mysql-5.6.2 here: http://dev.mysql.com/downloads/mirror.php?id=402349#mirrors ... once finished, untar the file and do this:
mv path/to/mysql-5.6.2-m5-osx10.6-x86_64 /usr/local/mysql
echo "PATH=\$PATH:/usr/local/mysql/bin" >> ~/.profile
# open a new tab
cd /usr/local/mysql #this is essential!
./scripts/mysql_install_db
mysqld_safe &
mysql -uroot
works for me :)
You need to set up your path environment too, and it's also good practise to set a root password while you're at it. I've created a full step-by-step here: How to install MySQL on Lion (Mac OS X )
All,
I was having issues with connecting to my DB through Tomcat, yet could through the MySql tool. Tomcat was accessing it through the actual IP of my machine (10.0.x.x) instead of through localhost or 127.0.0.1. Turns out that when I migrated from SL to Lion, remote connections were disabled. Once I enabled them, it worked fine.
Hopefully this helps someone.
I had MySQL installed already, but after upgrading to Lion it would no longer start.
I tried installing the latest official version and it still wouldn't start.
Finally, this fixed it:
$ sudo mkdir /var/log/mysql
$ sudo chown mysql:mysql /var/log/mysql
