centos7 安装mysql

//dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm # 安装mysql源 yum localinstall mysql57-community-release-el7-8.noarch.rpm

检查mysql源是否安装成功

yum repolist enabled | grep "mysql.*-community.*"

看到上图所示表示安装成功。 

2、安装MySQL

yum install mysql-community-server

3、启动MySQL服务

systemctl start mysqld

查看mysql启动状态

systemctl status mysqld

 

 

4、设置开机启动

systemctl enable mysqld
systemctl daemon-reload

5、修改root本地登录密码

mysql安装完成之后，在/var/log/mysqld.log文件中给root生成了一个默认密码。通过下面的方式找到root默认密码，然后登录mysql进行修改：

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

红框位置显示临时密码

mysql -u root -p
set password for ‘root‘@‘localhost‘=password(‘MyNewPass4!‘);

6、设置支持root远程登录

grant all privileges on *.* to ‘root‘@‘%‘ identified by ‘登录密码‘ with grant option;
flush privileges;
