方法一下載安裝：

1、在/home建立mysql目錄，下載如下四個軟體包

http://mirrors.sohu.com/mysql/MySQL-5.7/

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-client-5.7.18-1.el6.x86_64.rpm

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-common-5.7.18-1.el6.x86_64.rpm

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-libs-5.7.18-1.el6.x86_64.rpm

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-community-server-5.7.18-1.el6.x86_64.rpm

2、檢查mysql rpm相關的包是否安裝並去除

[[email protected] mysql]# rpm -qa | grep -i mysql

mysql-libs-5.1.73-8.el6_8.x86_64

[[email protected] mysql]# rpm -e mysql-libs-5.1.73-8.el6_8.x86_64

error: Failed dependencies:

libmysqlclient.so.16()(64bit) is needed by (installed) postfix-2:2.6.6-8.el6.x86_64

libmysqlclient.so.16(libmysqlclient_16)(64bit) is needed by (installed) postfix-2:2.6.6-8.el6.x86_64

mysql-libs is needed by (installed) postfix-2:2.6.6-8.el6.x86_64

[[email protected] mysql]#

將依賴包一併刪除

[[email protected] mysql]# yum remove -y mysql-libs

再次查詢是否刪除乾淨

[[email protected] mysql]# rpm -qa | grep -i mysql

[[email protected] mysql]#

3、同時安裝這三個rpm包

rpm -ivh mysql-community-client-5.7.18-1.el6.x86_64.rpm mysql-community-common-5.7.18-1.el6.x86_64.rpm mysql-community-libs-5.7.18-1.el6.x86_64.rpm

方法二yum安裝：

首先要到MySQL yum庫的下載頁面http://dev.mysql.com/downloads/repo/yum/

下載：mysql57-community-release-el7-11.noarch.rpm

安裝：rpm -Uvh mysql57-community-release-el7-9.noarch.rpm

yum安裝server：

yum install mysql-community-server

yum安裝client：

yum install mysql-community-client
