centos7 安装mysql5.7.17

Centos7下安装mysql5.7.17

 

mysql的安装（root用户下）

wget http://mirrors.sohu.com/mysql/MySQL-5.7/mysql-5.7.17-1.el7.x86_64.rpm-bundle.tar

 

 

tar -xvf mysql-5.7.17-1.el7.x86_64.rpm-bundle.tar

安装时候会提示与已经安装的RPM包有冲突，所以我们先卸载一些RPM包，要卸载哪些呢？我们要卸载的是包含有mariadb关键字的RPM包，执行命令：rpm -qa|grep mariadb来查看一下我们要卸载哪些软件

 rpm -qa | grep mariadb

 rpm -e --nodeps mariadb-libs-5.5.50-1.el7_2.x86_64

 rpm -ivh mysql-community-common-5.7.17-1.el7.x86_64.rpm

 rpm -ivh mysql-community-libs-5.7.17-1.el7.x86_64.rpm

 libnuma.so.1()(64bit) is needed by mysql

 yum install numactl

 rpm -ivh mysql-community-server-5.7.17-1.el7.x86_64.rpm
