CentOS 7中安装mysql server的步骤

之前一直用RHEL 6.3和6.4，系统盘里自带了mysql server，配置好yum源后，直接yum install mysql-server就可安装mysql服务器端了，最近用CentOS 7.1，发现系统盘没有提供mysql-server的RPM包，在网上搜罗了半天，最后在mysql的官方网站找到答案。 

只需在/etc/yum.repos.d/目录下添加如下文件mysql-community.repo文件，内容以下： 
 

# Enable to use MySQL 5.6
[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/5/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

以上对应的是5.6版本。 

5.7版本的内容以下： 
 

# Note: MySQL 5.7 is currently in development. For use at your own risk.
# Please read with sub pages: https://dev.mysql.com/doc/relnotes/mysql/5.7/en/
[mysql57-community-dmr]
name=MySQL 5.7 Community Server Development Milestone Release
baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/
enabled=1
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

最后执行 
 

yum install mysql-community-server

便可。 

我用的是5.6版本的内容，在安装的过程当中，报如下错误： 
 

GPG key retrieval failed: [Errno 14] curl#37 - "Couldn't open file /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql"

很显然，本地没有RPM-GPG-KEY-mysql文件，因而对上文的mysql-community.repo作了一下修改，修改后的内容以下： 
 

[mysql56-community]
name=MySQL 5.6 Community Server
baseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/5/$basearch/
enabled=1
gpgcheck=0

从新执行 
 

yum install mysql-community-server

命令，安装OK~
