yum更换

1.删除原有的自带的yum

rpm -qa|grep yum
rpm -qa|grep yum|xargs rpm -e --nodeps

找到subscription-manage的配置文件/etc/yum/pluginconf.d/subscription-manager.conf
[root@application-server pluginconf.d]# vim subscription-manager.conf

[main]
enabled=0 #将它禁用掉
~
…
[root@application-server pluginconf.d]#

2.下载yum源

https://vault.centos.org/7.2.1511/os/x86_64/Packages/

python-iniparse-0.4-9.el7.noarch.rpm
yum-3.4.3-132.el7.centos.0.1.noarch.rpm
yum-metadata-parser-1.1.4-10.el7.x86_64.rpm
yum-plugin-fastestmirror-1.1.31-34.el7.noarch.rpm
yum-updateonboot-1.1.31-34.el7.noarch.rpm
yum-utils-1.1.31-34.el7.noarch.rpm

3.安装rpm

rpm -ivh yum-*

4.修改yum 源 把原有的repo文件删除

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
sed -i  's/$releasever/7/g' /etc/yum.repos.d/CentOS-Base.repo
yum repolist 

5.刷新yum

yum clean all
yum makecache

6.安装测试

跟yum没关系

[root@localhost ~]# systemctl start keepalived //启动keepalived
[root@localhost ~]# systemctl enable keepalived //加入开机启动keepalived
[root@localhost ~]# systemctl restart keepalived //重新启动keepalived
[root@localhost ~]# systemctl status keepalived //查看keepalived状态
