yum安装MySQL指定版本

默认yum只能安装mysql 5.1，我们可以自己配置通过yum安装5.6或者其他版本。

1. 查看系统里面有没有mysql 的repo

yum repolist all | grep mysql

2. 如果没有发现，则需要配置repo

只能有一个是 enabled=1的，其他的都得enabled=0。

vim /etc/yum.repos.d/mysql-community.repo

输入如下内容

[mysql-connectors-community]name=MySQL Connectors Communitybaseurl=http://repo.mysql.com/yum/mysql-connectors-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql[mysql-tools-community]name=MySQL Tools Communitybaseurl=http://repo.mysql.com/yum/mysql-tools-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql# Enable to use MySQL 5.5[mysql55-community]name=MySQL 5.5 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.5-community/el/6/$basearch/enabled=0gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql# Enable to use MySQL 5.6[mysql56-community]name=MySQL 5.6 Community Serverbaseurl=http://repo.mysql.com/yum/mysql-5.6-community/el/6/$basearch/enabled=1gpgcheck=1gpgkey=file:/etc/pki/rpm-gpg/RPM-GPG-KEY-mysql# Note: MySQL 5.7 is currently in development.

3. 再看看是否存在mysql的repo

yum repolist enabled | grep mysql

可以看到已经有了

4. 签名

vim /etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
