cnetos7.0 安装mysql

时间：2022-09-28 19:09:04

CentOS 7的yum源中貌似没有正常安装mysql时的mysql-sever文件，需要去官网上下载

[root@localhost ~]# wget https://mirrors.tuna.tsinghua.edu.cn/mysql/yum/mysql-connectors-community-el7/mysql-community-release-el7-5.noarch.rpm

[root@localhost ~]# rpm -ivh mysql-community-release-el7-5.noarch.rpm

[root@localhost ~]# yum install mysql-community-server

成功安装之后重启mysql服务

[root@localhost ~]# /bin/systemctl restart mysqld.service

初次安装mysql是root账户是没有密码的成功安装之后重启mysql服务,

这里我顺带把远程root用户也设定了，

设置密码的方法

[root@localhost ~]# mysql -uroot

mysql> use mysql;

mysql> UPDATE user SET Password = PASSWORD('newpassword') WHERE user = 'root' and host='localhost'; //设置本地root用户密码

mysql> GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'newpassword' WITH GRANT OPTION;   //创建远程root用户并设置密码

mysql> flush privileges;

mysql> exit;　　

ok，搞定！
