centos7下快速安装mysql

1.centos7 自带mariadb   可以通过yum install mariadb mariadb-libs mariadb-devel安装

2.安装mysql

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

# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-5.noarch.rpm
# yum install mysql-community-server
成功安装之后重启mysql服务
service mysqld start

初次安装mysql是root账户是没有密码的

设置密码的方法

# mysql -uroot
mysql> set password for ‘root’@‘localhost’ = password('mypasswd');
mysql> exit
搞定！

远程授权连接mysql
GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'mypassword' WITH GRANT OPTION;
FLUSH PRIVILEGES;
