=====================
一，修改yum源

[root@bogon yum.repos.d]# cat CentOS-Base.repo
# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.
#
#
[base]
name=CentOS-$releasever - Base
#mirrorlist=
baseurl=
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#released updates
[updates]
name=CentOS-$releasever - Updates
#mirrorlist=
baseurl=
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#additional packages that may be useful
[extras]
name=CentOS-$releasever - Extras
mirrorlist=
#baseurl=
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
#additional packages that extend functionality of existing packages
[centosplus]
name=CentOS-$releasever - Plus
mirrorlist=
#baseurl=
gpgcheck=1
enabled=0
gpgkey=

二。执行命令将7.5更新为7.6，完成后重启即可

yum update -y
======================
操作记录如下：

[root@jwbdb alpha]# chkconfig –list yum-updatesd

yum-updatesd    0:关闭  1:关闭  2:启用  3:启用  4:启用  5:启用  6:关闭

[root@jwbdb alpha]# service yum-updatesd stop

停止 yum-updatesd：                                        [确定]

[root@jwbdb alpha]# service yum-updatesd status

yum-updatesd 已停

[root@jwbdb alpha]# chkconfig –level 35 yum-updatesd off

[root@jwbdb alpha]# chkconfig –list yum-updatesd

yum-updatesd    0:关闭  1:关闭  2:启用  3:关闭  4:启用  5:关闭  6:关闭

===更换yum==========================
# 对于 CentOS 7
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
-e 's|^#baseurl=http://mirror.centos.org|baseurl=https://mirrors.tuna.tsinghua.edu.cn|g' \
-i.bak \
/etc/yum.repos.d/CentOS-*.repo

# 对于 CentOS 8
sudo sed -e 's|^mirrorlist=|#mirrorlist=|g' \
-e 's|^#baseurl=http://mirror.centos.org/$contentdir|baseurl=https://mirrors.tuna.tsinghua.edu.cn/centos|g' \
-i.bak \
/etc/yum.repos.d/CentOS-*.repo
=============================================
更换yum源
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
更换epel源
wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
————————————————
#更新缓存
sudo yum makecache
yum clean all
#重启
init 6
更新源
#yum update
#升级
yum upgrade
===========
# 此条不用 yum --disablerepo='*' --enablerepo='C7.5*' upgrade
#检查内核版本
yum info kernel -q
#查看现在可用仓库列表
yum repolist
# 查看现在可用仓库版本
yum list updates | grep "centos-release"
#清空本地缓存
yum clean all
rm -rf /var/cache/yum
# 版本升级
yum -y update
# 查看更新后的版本
cat /etc/redhat-release
备份过渡的repo仓库文件，启用新版的仓库文件
# mv /etc/yum.repos.d/CentOS-Vault.repo /etc/yum.repos.d/backup/
# mv /etc/yum.repos.d/CentOS-Vault.repo.rpmnew /etc/yum.repos.d/CentOS-Vault.repo
清空本地缓存，更新版本库文件
# yum clean all
# yum makecache

====删除kubeadm==============
#在卸载K8s组件前，先执行kubeadm reset命令，清空K8s集群设置
kubeadm reset
#把之前通过yum安装的管理组件卸载
yum erase -y kubelet kubectl kubeadm kubernetes-cni
#基础组件通过Docker镜像部署，因此只需要强制删除对应镜像即可卸载
docker kill $(docker ps -q) ; docker rm $(docker ps -a -q) ; docker rmi $(docker images -q -a)
=====批量删除================
kubeadm reset
yum erase -y kubelet kubectl kubeadm kubernetes-cni
docker kill $(docker ps -q) ; docker rm $(docker ps -a -q) ; docker rmi $(docker images -q -a)
yum remove docker \
docker-ce\
docker-ce-cli\
docker-ce-rootless-extras\
docker-scan-plugin\
