# 安装部署数据库 #

本文使用MySQL5.7  
下载安装数据库repo文件  
wget https://dev.mysql.com/get/mysql80-community-release-el7-2.noarch.rpm  
rpm -ivh mysql80-community-release-el7-2.noarch.rpm  
修改repo文件 将默认的8.0版本改成5.7  
vi /etc/yum.repos.d/mysql-community.repo

# Enable to use MySQL 5.7
    [mysql57-community]
    name=MySQL 5.7 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
    enabled=0
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
    
    [mysql80-community]
    name=MySQL 8.0 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql

改为下面的，也就是说启用mysql5.7的版本

# Enable to use MySQL 5.7
    [mysql57-community]
    name=MySQL 5.7 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-5.7-community/el/7/$basearch/
    enabled=1
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
    
    [mysql80-community]
    name=MySQL 8.0 Community Server
    baseurl=http://repo.mysql.com/yum/mysql-8.0-community/el/7/$basearch/
    enabled=0
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-mysql
