linux 安装mysql

操作系统：CentOS 6.8

MySQL版本：Community 5.7.17

预备：下载MySQL的common, libs, client, devel, server五个rpm包，CentOS对应的版本是RedHat/Oracle

注：使用root用户安装，非root用户只能用源码编译安装

1. 查看是否已安装了MySQL相关组件

rpm -qa | grep -i mysql

3. 用rpm方式安装MySQL（有依赖关系，按照下面顺序装）

rpm -ivh mysql-community-common-5.7.17-1.el6.x86_64.rpm
rpm -ivh mysql-community-libs-5.7.17-1.el6.x86_64.rpm
rpm -ivh mysql-community-client-5.7.17-1.el6.x86_64.rpm
rpm -ivh mysql-community-devel-5.7.17-1.el6.x86_64.rpm

　　注：MySQL 5.7版本增加了密码强度验证插件，安装的时候会默认生成root密码，可在 /var/log/mysqld.log文件中搜索字符串”A temporary password is generated for root@localhost:”查看

[root@localhost /]# rpm -ivh mysql-community-server-5.7.11-1.el6.x86_64.rpm
