Centos7中yum安装MySQL

1. 安装mysql

   [root@localhost ~]# yum update
   [root@localhost ~]# cat /etc/redhat-release
   CentOS Linux release 7.4. (Core)
   [root@localhost ~]# yum install mysql
   [root@localhost ~]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
   [root@localhost ~]# rpm -ivh mysql-community-release-el7-.noarch.rpm
   [root@localhost ~]# yum install mysql-community-server
   [root@localhost ~]# yum install mysql-devel
   [root@localhost ~]# service mysqld restart

2. 配置MySQL

安装成功后重启MySQL服务

初次安装mysql，root账户没有密码，设置root密码

[root@localhost ~]# mysql -u root
mysql> set password for 'root'@'localhost' =password('password');

注：root为数据库账号，password为数据库密码。

开启MySQL远程连接

mysql> GRANT ALL PRIVILEGES ON *.* TO root@'%' IDENTIFIED BY 'password' WITH GRANT OPTION;
mysql> flush privileges;
