CCIE那点事

1.停用应用

2.备用所有库

3.增加源

  curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
  wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo

https://repo.mysql.com/

5.5.35 https://repo.mysql.com/yum/mysql-5.5-community/el/7/x86_64/mysql-community-server-5.5.35-2.el7.x86_64.rpm

5.6.34 https://repo.mysql.com/yum/mysql-5.6-community/el/7/x86_64/mysql-community-server-5.6.35-2.el7.x86_64.rpm

yum -y install gcc gcc-c++ make cmake automake autoconf libxml2 libxml2-devel zlib zlib-devel ncurses ncurses-devel
yum -y install libaio libaio-devel net-tools wget

wget https://repo.mysql.com/yum/mysql-5.5-community/el/7/x86_64/mysql-community-common-5.5.35-2.el7.x86_64.rpm
wget https://repo.mysql.com/yum/mysql-5.5-community/el/7/x86_64/mysql-community-libs-5.5.35-2.el7.x86_64.rpm
wget https://repo.mysql.com/yum/mysql-5.5-community/el/7/x86_64/mysql-community-client-5.5.35-2.el7.x86_64.rpm

wget https://repo.mysql.com/yum/mysql-5.6-community/el/7/x86_64/mysql-community-common-5.6.34-2.el7.x86_64.rpm
wget https://repo.mysql.com/yum/mysql-5.6-community/el/7/x86_64/mysql-community-libs-5.6.34-2.el7.x86_64.rpm
wget https://repo.mysql.com/yum/mysql-5.6-community/el/7/x86_64/mysql-community-client-5.6.34-2.el7.x86_64.rpm
按顺序安装
mysql-community-common
mysql-community-libs
mysql-community-client
mysql-community-server

4.在线升级

5.备用方案。卸载后再安装，再导入数据

6.回退方案
