yum离线安装mysql

1.开起yum缓存,把keepcache改成1
vi /etc/yum.conf
keepcache=1
2.在全新的安装的 有网的机器上系统上安装mysql
wget -i -c http://dev.mysql.com/get/mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql57-community-release-el7-10.noarch.rpm
yum -y install mysql-community-server
3.打包并下载yum缓存
cd /var/cache
zip -r yum.zip yum/*
sz yum.zip
cd ~
sz mysql57-community-release-el7-10.noarch.rpm
4.在没有网的机器,重做第1步,并把yum.zip,mysql57-community-release-el7-10.noarch.rpm上传对应目录并解压
cd /var/cache
rm -rf yum
unzip yum.zip
cd ~
yum -y localinstall mysql57-community-release-el7-10.noarch.rpm #yum本地安装
yum -y -C install mysql-community-server #yum缓存安装

最保险的做法就是两个系统都是全新安装的centos.

vim /etc/my.cnf
在[mysqld] 下面加
skip-grant-tables
service mysqld restart
