大佬教程收集整理的这篇文章主要介绍了yum install mysql-community-server rpm方式安装mysql(社区版)，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。
查看操作系统版本[root@fp-web-118 local]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)安装之前需要检查一下机器上是否有mysql.
执行安装命令[root@fp-web-118 local]# yum install mysql-community-serverLoaded plugins: fastestmirror, langpacksDetermining fastest mirrors * base: mirrors.aliyun.com * extras: mirrors.aliyun.com * updates: mirrors.aliyun.comNo package mysql-community-server available.Error: Nothing to do安装错误，查看yum 源

GPG key retrieval failed: [Errno 14] curl#37 - "Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql"解决这个问题
gpg key retrieval failed 意思是在/etc/pki/rpm-gpg/中找不到RPM-GPG-KEY-mysql第一种方案，设置gpgcheck为0，就是不需要检查gpgkey。# enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=0#gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql 第二种方案，指定外网gpgkey的值# enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=0 gpgkey=http://springdale.math.ias.edu/data/puias/6/x86_64/os/RPM-GPG-KEY-puias
第三种方案，下载gpgkey//下载RPM-GPG-KEY-mysqlwget http://repo.mysql.com/RPM-GPG-KEY-mysql -O /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
