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
