The installation is mainly divided into the following steps.
The main difference between wsl and ordinary ubuntu installation is that an error will be reported when starting mysql. Ordinary ubuntu's mysql will also run automatically after the installation is completed.
No installation can be skipped
sudo apt-get remove --purge *mysql*
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get remove --purge *mariadb*
2. Update source
sudo apt update
sudo apt upgrade
3. Install mysql server
sudo apt install mysql-server
4. Start mysql
sudo service mysql start
1. Start mysql:
Method one: sudo /etc/init.d/mysql start
Method two:sudo service mysql start
2. Stop mysql:
Method one: sudo /etc/init.d/mysql stop
Method two:sudo service mysql stop
3. Restart mysql:
Method one: sudo/etc/init.d/mysql restart
Method two:sudo service mysql restart
Note: If it cannot be started cat /var/log/mysql/error.log, check the error log and find that the port is occupied , so it cannot be started. It is found that Ubuntu and Windows of wsl have public ports, so use the command under cmd netstat -ano| findstr 3306to check the pid and remember (the last column), and open the task Manager, open details, close that pid and restart mysql, success. (This is a problem unique to wsl)
5. Set the username and password (if set during the installation process, you can skip the following)
Take a look at the account and password given by the system by default, and use them to log in to mysql.
sudo cat /etc/mysql/debian.cnf
mysql -u默认用户名 -p默认密码
Reset username and password
use mysql;
update mysql.user set authentication_string=password('123456') where user='root' and Host ='localhost';
update user set plugin="mysql_native_password";
flush privileges;
quit;
Note: Use the following code to set the password for mysql80
use mysql;
alter user 'root'@'localhost' identified with mysql_native_password by '123456';
flush privileges;
