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

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。
