CentOS7 下的mysql安装与配置
之前虽然也安装过多次mysql，但每次都会遇到各种小问题，这次记录下来，以备后查。
首先是下载与安装
# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
# rpm -ivh mysql-community-release-el7-.noarch.rpm
# yum install mysql-community-server
安装过程中间会出现选择y/n的，直接输入y即可，如下：
[root@APP1 /]# wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm

设置允许远程连接
mysql> grant all privileges on *.* to root@'%'identified by 'password';

如果允许root账号远程连接要对系统数据库的root账户设置远程访问的密码，与本地的root访问密码并不冲突。
1 grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option; #123456为你需要设置的密码
