centos6/7 yum安装mysql其它版本(mysql5.7/5.6)

对于mysql，是越来越不想花时间安装了，但yum的自带版本太低，必须简单处理下。

yum list installed | grep mysql
#移除已安装的
yum remove mysql-libs.x86_64

yum list installed | grep mysql

#确保没有后下载mysql5.7
wget https://dev.mysql.com/get/mysql57-community-release-el6-9.noarch.rpm
#centos7
wget https://dev.mysql.com/get/mysql57-community-release-el7-9.noarch.rpm
rpm -Uvh mysql57-community-release-el6-9.noarch.rpm

#如果安装mysql5.6
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
service mysqld start

#自动生成的root密码
grep 'temporary password' /var/log/mysqld.log
#登录后修改密码
set password='e1T&VkRu31V1LJ3';
flush privileges;
