[数据库]CentOS 7中如何安装mysql server


以前一直用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/目录下添加以下文件mysql-community.repo文件,内容如下:

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

以上对应的是5.6版本。

5.7版本的内容如下:

# 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 Releasebaseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

最后执行yum install mysql-community-server即可。

我用的是5.6版本的内容,在安装的过程中,报以下错误:

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,于是对上文的mysql-community.repo做了一下修改,修改后的内容如下:

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

重新执行yum install mysql-community-server命令,安装OK~
