1. 安装
apt-get install mysql-server即可
版本是5.7.30
2. 运行
service mysql start
(需要注意，一定要有/etc/mysql目录的存在，不然可能只看到出错，但没有日志）
3. 登录
初始密码是在/etc/mysql/debian.cnf中
mysql -u debian-sys-maint -p
mysql> use mysql;
mysql> update mysql.user set authentication_string=password(‘123456‘) where user=‘root‘ and Host=‘localhost‘;
mysql> update user set plugin="mysql_native_password";
mysql> flush privileges;
mysql> quit;
# service mysql restart
mysql -uroot -p 用新设置的密码登录
4. 配置远程访问
mysql> create database qcqc;
mysql> GRANT ALL PRIVILEGES ON qqqc.* TO sss@localhost IDENTIFIED BY "123456";
mysql> GRANT ALL PRIVILEGES ON qqqc.* TO sss@"%" IDENTIFIED BY "654321";
mysql> flush privileges;
5. 配置一个utf8数据库
CREATE DATABASE IF NOT EXISTS yourdbname DEFAULT CHARSET utf8 COLLATE utf8_general_ci;
