1.下载 MySQL yum包

wget http://repo.mysql.com/mysql57-community-release-el7-10.noarch.rpm

2.安装MySQL源

rpm -Uvh mysql57-community-release-el7-10.noarch.rpm

3.安装MySQL服务端,需要等待一些时间

yum install -y mysql-community-server

4.启动MySQL

systemctl start mysqld.service

5.检查是否启动成功

systemctl status mysqld.service

6.获取临时密码，MySQL5.7为root用户随机生成了一个密码

grep 'temporary password'/var/log/mysqld.log

7.通过临时密码登录MySQL，进行修改密码操作

mysql -uroot -p

8.因为MySQL的密码规则需要很复杂，我们一般自己设置的不会设置成这样，所以我们全局修改一下

mysql> set global validate_password_policy=0;

mysql> set global validate_password_length=1;

这时候我们就可以自己设置想要的密码了

ALTERUSER'root'@'localhost'IDENTIFIEDBY'yourpassword';

9.授权其他机器远程登录

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'yourpassword' WITH GRANT OPTION; FLUSH PRIVILEGES;

10.开启开机自启动

先退出mysql命令行，然后输入以下命令

systemctl enable mysqldsystemctl daemon-reload

11.设置MySQL的字符集为UTF-8，令其支持中文

vim /etc/my.cnf

改成如下,然后保存
