在CentOS上安装Mysql，留存记录，待以后查看。参考Mysql官网的 Installing MySQL on Linux Using the MySQL Yum Repository。
安装准备
系统信息
命令：uname -a
[root@localhost /]# uname -a
Linux localhost.localdomain 3.10.0-327.el7.x86_64 #1 SMP Thu Nov 19 22:10:57 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
检测是否安装
命令：rpm -qa | grep mysql，搜索指定rpm包是否安装。
安装前先检测系统中是否安装有mysql，如果有则可以先将原有的数据库卸载。我已经安装好了，信息为：
[root@localhost /]# rpm -qa | grep mysql
mysql-community-devel-5.6.35-2.el7.x86_64
mysql-community-libs-5.6.35-2.el7.x86_64
mysql-community-release-el7-5.noarch
mysql-community-client-5.6.35-2.el7.x86_64
mysql-community-server-5.6.35-2.el7.x86_64
mysql-community-common-5.6.35-2.el7.x86_64
删除已有软件
如果已经有安装过，可以通过 rpm -e 命令 或者 rpm -e –nodeps 命令来卸载。
- 普通删除模式
[root@localhost /]# rpm -e mysql-community-devel
删除时也会报错，无法删除，因为有依赖关系存在：
[root@localhost /]# rpm -e mysql-community-libs
error: Failed dependencies:
libmysqlclient.so.18()(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
libmysqlclient.so.18()(64bit) is needed by (installed) perl-DBD-MySQL-4.023-5.el7.x86_64
libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) postfix-2:2.10.1-6.el7.x86_64
libmysqlclient.so.18(libmysqlclient_18)(64bit) is needed by (installed) perl-DBD-MySQL-4.023-5.el7.x86_64
mysql-community-libs(x86-64) >= 5.6.10 is needed by (installed) mysql-community-client-5.6.35-2.el7.x86_64
- 强力删除模式
如果使用上面命令删除时，提示有依赖的其它文件，则用该命令可以对其进行强力删除。
[root@localhost /]# rpm -e --nodeps mysql-community-common
在删除完以后可以通过 rpm -qa | grep mysql 命令来查看mysql是否已经卸载成功！！
安装
客户端
使用 yum install mysql，安装成功，过程提示：

开发包
服务端安装好后，需要安装 mysql-devel，包含了所需要的库和文件，如果需要编译其他Mysql客户程序，必须要安装。这里有一个解释:
That is what RPM-based Linuxes typically call the MySQL development
files package. Typically this is packaged separately from the MySQL
database program itself and the client programs.
安装过程：
[root@localhost /]# yum install mysql-devel

到这里就算安装成功了，还有对Mysql的一些配置，参见另外一篇文章。
总结
- 查看系统信息：uname -a；
- 查看是否安装：rpm -qa | grep mysql；
- 删除已安装软件：rpm -e mysql-community-devel 或 rpm -e –nodeps mysql-community-common ；
- 安装客户端：yum install mysql；
- 安装服务端：yum install mysql-server ，如果失败：
- 下载 wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm；
- 安装 rpm -ivh mysql-community-release-el7-5.noarch.rpm ；
- 服务端：yum install mysql-community-server；
- 安装开发包：yum install mysql-devel；
- 完成，测试。
