1、安装

# 安装mysql服务

sudo apt-get install mysql-server

# 安装客户端

sudo apt install mysql-client

# 安装依赖

sudo apt install libmysqlclient-dev

# 检查状态

sudo netstat -tap | grep mysql

2、设置密码

root> mysql

mysql> update mysql.user set authentication_string=PASSWORD('123456'), plugin='mysql_native_password' where user='root';

mysql> flush privileges;

mysql> exit

Bye

# exit

$ sudo /etc/init.d/mysql restart

$ mysql -uroot -p

Enter password:

3、配置远程登录

注释的地方是允许非本地IP登录

# 修改配置文件，注释掉bind-address = 127.0.0.1

$ sudo vi /etc/mysql/mysql.conf.d/mysqld.cnf

# 保存退出，然后进入mysql服务，执行授权命令：

$ mysql -uroot -p

mysql> grant all on *.* to root@'%' identified by '123456' with grant option;

Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;

Query OK, 0 rows affected (0.00 sec)

mysql> exit

Bye

$ sudo /etc/init.d/mysql restart

4、注释这一行

5、最后一步，配置腾讯云安全组，放通3306端口
