I've been trying to install mysql using WSL and I've followed the steps indicated in this guide https://learn.microsoft.com/en-us/windows/wsl/tutorials/wsl-database. I tried running mysql --version and it worked (prompted mysql Ver 8.0.23 for Linux on x86_64 (MySQL Community Server - GPL)). But as I try the next command sudo /etc/init.d/mysql start, it says sudo: /etc/init.d/mysql: command not found. I've also tried checking the contents of /etc/init.d/ directory and there is no existing mysql file/folder there. What should I do next to proceed with my mysql installation?
Thanks!
There is a great blog post on this problem, with explanations of the issue and detailed solutions.
https://www.58bits.com/blog/2020/05/03/installing-mysql-80-under-wsl-2-and-ubuntu
From the post:
One solution is to download the mysql.server.sh script from here -
https://github.com/mysql/mysql-server/tree/8.0/support-files - and
then copy and rename the script to /etc/init.d/mysql (make sure that
it's also executable - chmod +x mysql)
You'll then need to set the default values for basdir, datadir and pid
file locations.
Here's an excerpt with the top portion of the file and the settings
that worked for me...
# If you change base dir, you must also change datadir. These may get
# overwritten by settings in the MySQL configuration files.
basedir=/usr
datadir=/var/lib/mysql
# Default value, in seconds, afterwhich the script should timeout waiting
# for server start.
# Value here is overriden by value in my.cnf.
# 0 means don't wait at all
# Negative numbers mean to wait indefinitely
service_startup_timeout=900
# Lock directory for RedHat / SuSE.
lockdir='/var/lock/subsys'
lock_file_path="$lockdir/mysql"
# The following variables are only set for letting mysql.server find things.
# Set some defaults
mysqld_pid_file_path=/var/run/mysqld/mysqld.pid
if test -z "$basedir"
After this you should be able to start and stop MySQL as follows:
sudo service mysql start
sudo service mysql stop
As he mentions later, you also need to create /var/run/mysqld/ and set permissions:
sudo mkdir /var/run/mysqld
sudo chown mysql:mysql /var/run/mysqld
I have been working with MariaDB and i don't know why there is no my.cnf. But the crazy thing is that:
Where it is suposed that the file should be, there is only the my.cnf.d, but the .cnf isn't.
If i write a new file called my.cnf and i copy from another server, it works.
I want to know why happen this?
PD: This is my instalation via yum:
sudo yum install MariaDB-server MariaDB-client
sudo systemctl start mariadb
mysql_secure_installation
Depending on the specific version there may be no my.cnf file. See MariaDB KB
MariaDB will use compiled defaults if there is no my.cnf to override them. You can use my.cnf.d as a starting point for that.
I just installed mysql via homebrew and I wanted to change the location where mysql stores the databases. All the stuff I've found so far online have paths that I don't understand and don't exist on my machine (OSX 10.8).
Any help is greatly appreciated. Thanks.
If you have MySQL running a simple ps ax | grep mysql will yeld the process path.
Otherwise search your fs for mysqld it will take some time but will get the job done:
sudo find / -type f -name "mysqld"
A find / | grep mysql will print every file containing mysql in its name.
Use MySQLWorkbench, it has a nice GUI which lets you configure INNODBs data path and will also help you managing your instances.
Otherwise edit /etc/my.cnf (or create it if you don't have any) insert a [mysqld] section and set innodb_data_home_dir = /path/to/where/you/moved/your/data
[mysqld]
innodb_data_home_dir = /path/to/where/you/moved/your/data
When started via homebrew services:
Stop the server: brew services stop mysql#5.6
Modify the plist file for your installed version, for example: /usr/local/Cellar/mysql#5.6/5.6.43/homebrew.mxcl.mysql#5.6.plist
Look for the --datadir=/usr/local/var/mysql key and set the value to the place you want to store your databases.
Copy over files from /usr/local/var/mysql to your new location.
Restart the server: brew services start mysql#5.6
For homebrew mysql installs, where's my.cnf? Does it install one?
There is no my.cnf by default. As such, MySQL starts with all of the default settings. If you want to create your own my.cnf to override any defaults, place it at /etc/my.cnf.
Also, you can run mysql --help and look through it for the conf locations listed.
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/etc/my.cnf ~/.my.cnf
The following groups are read: mysql client
The following options may be given as the first argument:
--print-defaults Print the program argument list and exit.
--no-defaults Don't read default options from any option file.
--defaults-file=# Only read default options from the given file #.
--defaults-extra-file=# Read this file after the global files are read.
As you can see, there are also some options for bypassing the conf files, or specifying other files to read when you invoke mysql on the command line.
The homebrew mysql contains sample configuration files in the installation's support-files folder.
ls $(brew --prefix mysql)/support-files/my-*
If you need to change the default settings you can use one of these as a starting point.
cp $(brew --prefix mysql)/support-files/my-default.cnf /usr/local/etc/my.cnf
As #rednaw points out, a homebrew install of MySQL will most likely be in /usr/local so the my.cnf file should not be added to the system /etc folder, so I’ve changed the command to copy the file into /usr/local/etc.
If you are using MariaDB rather than MySQL use the following:
cp $(brew --prefix mariadb)/support-files/my-small.cnf /usr/local/etc/my.cnf
One way to find out:
sudo /usr/libexec/locate.updatedb
# wait a few minutes for it to finish
locate my.cnf
in my system it was
nano /usr/local/etc/my.cnf.default
as template and
nano /usr/local/etc/my.cnf
as working.
Nothing really helped me - I could not overwrite settings in a /etc/my.cnf file.
So I searched like John suggested https://stackoverflow.com/a/7974114/717251
sudo /usr/libexec/locate.updatedb
# wait a few minutes for it to finish
locate my.cnf
It found another my.cnf in
/usr/local/Cellar/mysql/5.6.21/my.cnf
changing this file worked for me! Don't forget to restart the launch Agent:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
Update:
If you have a fairly recent installation of homebrew you should use the brew services commands to restart mysql (use your installed homebrew mysql version, i.e. mysql or mysql#5.7):
brew services stop mysql
brew services start mysql
Since mysql --help shows a list of files, I find it useful to pipe the result to ls to see which of them exist:
$ mysql --help | grep /my.cnf | xargs ls
ls: /etc/my.cnf: No such file or directory
ls: /etc/mysql/my.cnf: No such file or directory
ls: ~/.my.cnf: No such file or directory
/usr/local/etc/my.cnf
For my (Homebrew installed) MySQL 5.7, it seems the files is on /usr/local/etc/my.cnf.
Add another answer cause
The accepted anwser is right. Since we're talking about Homebrew installed mysql, not MySQL installed manually, there's more direct way to find the conf.
The former answers may be a little outdated, Homebrew on M1 Mac is stored in a different location
Conf
The my.cnf is copied by Homebrew to following places during installation
/usr/local/etc/my.cnf for x86 Mac
/opt/homebrew/etc/my.cnf for M1 Mac
Homebrew chooses /usr/local, or /opt/homebrew to store packages, so the default conf files are not stored in /etc/ but /usr/local/etc or /opt/homebrew/etc.
In fact, homebrew changed the -DSYSCONFDIR= (default conf location) flag during compiling mysql from source.
Start the Service
A short answer: run brew info mysql and check the tips.
The recommended way is brew services start mysql, which uses the launchd to manage services. (launchd is deemed a systemd alternative on macOS)
For anyone wanna start it manually, mysql.start without any option is enough to start the service. (mysql.start is a script provided by mysql to help start the service)
On your shell type my_print_defaults --help
At the bottom of the result, you should be able to see the file from which the server reads the configurations. It prints something like this:
Default options are read from the following files in the given order:
/etc/my.cnf /etc/mysql/my.cnf /usr/local/etc/my.cnf ~/.my.cnf
Server version: 8.0.19 Homebrew. macOS Catalina 10.15.5 and installed MySQL via Homebrew. Found this file here:
/usr/local/etc/my.cnf
This solution helped :)
You can find where the my.cnf file has been provided by the specific package, e.g.
brew list mysql # or: mariadb
In addition to verify if that file is read, you can run:
sudo fs_usage | grep my.cnf
which will show you filesystem activity in real-time related to that file.
I believe the answer is no. Installing one in ~/.my.cnf or /usr/local/etc seems to be the preferred solution.
run
sudo find / -name my.cnf
Usually the first result is the correct one.
Should be in
/usr/local/etc/
In case of Homebrew, mysql would also look for my.cnf in it's Cellar directory, for example:
/usr/local/Cellar/mysql/5.7.21/my.cnf
For the case one prefers to keep the config close to the binaries - create my.cnf here if it's missing.
Restart mysql after change:
brew services restart mysql
If you are using mac m1 (Apple silicon), the my.cnf is located at
/opt/homebrew/etc/my.cnf
and can also be found by mysql --help
I have installed MySQL 5.7 using Homebrew
my.cnf file is located in "/opt/homebrew/etc/my.cnf"
For MacOS (High Sierra), MySQL that has been installed with home brew.
Increasing the global variables from mysql environment was not successful. So in that case creating of ~/.my.cnf is the safest option. Adding variables with [mysqld] will include the changes (Note: if you change with [mysql] , the change might not work).
<~/.my.cnf> [mysqld] connect_timeout = 43200 max_allowed_packet =
2048M net_buffer_length = 512M
Restart the mysql server. and check the variables.
y
sql> SELECT ##max_allowed_packet;
+----------------------+ | ##max_allowed_packet |
+----------------------+ | 1073741824 |
+----------------------+
1 row in set (0.00 sec)
$ps aux | grep mysqld
/usr/local/opt/mysql/bin/mysqld --basedir=/usr/local/opt/mysql --datadir=/usr/local/var/mysql --plugin-dir=/usr/local/opt/mysql/lib/plugin
Drop your my.cf file to /usr/local/opt/mysql
brew services restart mysql
I just installed mysql on a mac running 10.6. The mysql version is 5.1.56. I need to have mysql run on port 3307. This article says we can change the port by modifying this file:
# vi /etc/my.cnf
http://www.cyberciti.biz/faq/change-default-mysql-port-under-linuxunix/
but there is no such file in /etc. I can see mysql is running ok because I can connect to it just fine, is the way we change the port # different now?
Thanks
Looks like the new installers are adding the port as 3307
To change that follow below steps
sudo vi /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
change 3307 from this line <string>--port=3307</string> to 3306
On OSX you can create /etc/my.cnf if it does not exist. You can base it on samples found in /usr/local/mysql/support-files. Don't forget to restart MySQL for your my.cnf to take effect.
On MacOs High Sierra running MySql v8 server, you need the following:
Edit /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
Under ProgramArguments, you will see many entries with
<string>...</string> etc,
Add the following line: <string>--port=16000</string>
Also, to restart you need to do the following:
launchctl unload -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
and then
launchctl load -F /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
I hope this helps.
By default, the install doesn't create a my.cnf file on Snow Leopard. You can create one yourself under /etc or you can copy one from /usr/local/mysql/support-files/
Then run :
sudo cp my-huge.cnf /etc/my.cnf
Check out the explanation here
I experienced a similar problem and here's what worked for me. If you installed MySQL using brew install mysql then this should work for you.
For context, I'm using macOS Monterey 12, Homebrew 3.4.5, and MySQL 8.0.
MySQL is installed in:
/opt/homebrew/Cellar/mysql/8.0.28_1/
The configuration file my.cnf is located at /opt/homebrew/etc.
You can change the default port by specifying a new port in the my.cnf file.
First navigate to the homebrew etc folder
cd /opt/homebrew/etc
Append the new port value to the my.cnf file
echo "port = 3307" >> my.cnf
restart the MySQL service
brew services restart mysql
I tried a long time to get mysql running on my Mac (OSX 10.11.13) with mysql 5.7.11 to develop wordpress sites on my local machine...
When I used the app duplicator to migrate a website to my local machine I got errors during the database import. This was caused by to stricked sql_mode...
The trick that made it was:
Going to
/usr/local/mysql-5.7.11/support-files/
and copy the content from my-default.cnf
and paste it to
/etc/my.cnf (if this file does not exist create it!)
at the very last line of my.cnf I added:
sql_mode="NO_ENGINE_SUBSTITUTION"
Et voilà: sql_mode is changed permanently!
Whoop whoop!
I installed docker and was having problems with my company wanting to use port 3306 (which is what I was using privately).
Similar problem to you. So this is what I did to fix it.
sudo vi /Library/LaunchDaemons/com.oracle.oss.mysql.mysqld.plist
Then you get a long list of script tags and
Insert <string>--port=3307</string> into the array. Make sure you put it under the other strings and within the array.
I changed my port to 3307 instead of 3306 and now docker is working.
