Centos7安装MySql5.7

1.下载yum源：wget https://repo.mysql.com//mysql57-community-release-el7-11.noarch.rpm

2.安装yum源：rpm -Uvh mysql57-community-release-el7-11.noarch.rpm
3.查看有哪些版本的Mysql： yum repolist all | grep mysql

4：安装：yum install -y mysql-community-server

5.启动并查看状态：systemctl start mysqld systemctl status mysqld

6：获取自定义密码登陆数据库：grep ‘temporary password’ /var/log/mysqld.log

7：登陆数据库：mysql -uroot -p

8:更改密码：SET PASSWORD = PASSWORD(‘Admin123!’);注意，修改的密码太简单会不给修改，把大小写字母和数字加上就肯定可以了。然后切记切记，mysql里面的命令要加分号！分号！分号！

9：设置允许远程登陆：GRANT ALL PRIVILEGES ON . TO ‘root’@’%’ IDENTIFIED BY ‘Admin123!’ WITH GRANT OPTION;

10.刷新：flush privileges;

character-set-server=utf8
sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION
default-time_zone = ‘+8:00’

13：重启数据库：systemctl restart mysqld

14：设置开机启动：systemctl enable mysqld systemctl daemon-reload
