Two ways to install mysql in linux

1. Install to linux

1. Install mysql-server

1. Check whether mysql has been installed in the system before installation

ls /usr/share

2. Install mysql-server

sudo apt-get install mysql-server

3. Check again and find that there is an extra mysql

ls /usr/share | grep mysql	//在ls打印结果中搜索mysql关键字

4. Login
When creating mysql, the system creates an administrator account password by default

sudo cat /etc/mysql/debian.cnf

Log in with an administrator account:

mysql -u debian-sys-maint -p	//执行后输入密码

2. View mysql status

The following two commands have the same effect

sudo service mysql stauts
systemctl status mysql.service

3. Basic use of MySQL database

1. Start the MySQL database service

sudo service mysql start
或
sudo systemctl start mysql.service

2. Restart the MySQL database service

sudo service mysql restart
或
sudo systemctl restart mysql.service

3. Stop the MySQL database service

sudo service mysql stop
或
sudo systemctl stop mysql.service

4. View MySQL running status

sudo service mysql status
或
sudo systemctl status mysql.service

5. Set the MySQL service to start automatically

sudo service mysql enable
或
sudo systemctl enable mysql.service

6. Stop the MySQL service from starting at boot

sudo service mysql disable
或
sudo systemctl disable mysql.service

7. MySQL configuration file

sudo vim /etc/mysql/mysql.conf.d/mysqld.cnf

4. Update the root password

set password for root@localhost = password('123');
# alter user 'root'@'localhost' identified by '123';//上面的方法如果无效，尝试下这个

2. Install to Docker

1. Obtain the image

	docker pull mysql:5.7

2. Run the container (configure musql password: 123123)

docker run -d -p 3310:3306 \
       -v /home/mysql/conf:/etc/mysql/conf.d \
       -v /home/mysql/data:/var/lib/mysql \
       -e MYSQL_ROOT_PASSWORD=123123 \
       --name mysql01 \
       mysql:5.7
        
-d 后台运行
-v 挂载
-e 环境配置

3. View container information

docker ps			//看到mysql01已经启动

Three, install to window

Please refer to this tutorial: http://c.biancheng.net/view/2412.html

Fourth, connect to the mysql database

1. Login via command line

• If on linux, install sudo apt-get install mysql-clinet;
• If it is on the window, install mysql first, then enter: , and add the bin系统 > 高级系统设置 > 系统变量 > PATH directory under the mysql installation directory .
  

Execute the connection command:

mysql -u root -h 【mysql服务ip地址】 -P 【mysql服务端口】 -p
//输入密码后，就能登录

2. Client login

There are many interface-based mysql clients on windows, and the operation of mysql is very simple. For example: navigate, SQLyog, phpmyadmin.

5. Uninstall mysql

1. Uninstall from linux

sudo apt-get remove mysql-server
sudo apt-get autoremove

Check it after execution and find that mysql is gone

2. Uninstall from Docker

Then stop/delete the corresponding container directly.
