CentOS 7中安裝mysql server的步驟

之前一直用RHEL 6.3和6.4，系統盤裏自帶了mysql server，配置好yum源後，直接yum install mysql-server就可安裝mysql服務器端了，最近用CentOS 7.1，發現系統盤沒有提供mysql-server的RPM包，在網上搜羅了半天，最後在mysql的官方網站找到答案。 

只需在/etc/yum.repos.d/目錄下添加如下文件mysql-community.repo文件，內容以下： 
 

# 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

以上對應的是5.6版本。 

5.7版本的內容以下： 
 

# 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

最後執行 
 

yum install mysql-community-server

便可。 

我用的是5.6版本的內容，在安裝的過程當中，報如下錯誤： 
 

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

很顯然，本地沒有RPM-GPG-KEY-mysql文件，因而對上文的mysql-community.repo作了一下修改，修改後的內容以下： 
 

[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

從新執行 
 

yum install mysql-community-server

命令，安裝OK~
