公司有centos7.2和centos7.7系統百十臺，因辦公軟體的需要，要把所有的系統升級到centos7.9，百度了一下，還是覺得配置本地yum源比較合適，然後就是批量升級的操作了，別人建議使用ansible，可我沒學會，算了就使用py寫寫吧，步驟如下：
使用py批量登陸升級，因為root密碼都一樣，伺服器端可以聯網，客戶端皆不可以聯網
192.168.137.101 192.168.160.131 yum源伺服器，ftp192.168.160.129 客戶端，原來的系統centos7.2 3.10.0-327.el7.x86_64192.168.160.133 客戶端，原來的系統centos7.7 3.10.0-1062.el7.x86_64CentOS-7-x86_64-DVD-2009.iso 掛載
可以使用CentOS-7-x86_64-Everything-2009.iso
然後複製裡面的內容到本地目錄
創建目錄mkdir -p /data/CentOS7.9
mount /dev/cdrom /mnt (因為是vmware 直接掛載的，所以才這麼操作，如果你是直接複製iso到伺服器上的話，那你需要執行mount -t iso9660 -o loop /root/CentOS-7-x86_64-DVD-2009.iso /mnt)
複製光碟內容到指定的目錄內cp -R /mnt/* /data/CentOS7.9/
修改CentOS-Media.repo文件
cd /etc/yum.repos.d修改vi CentOS-Media.repo 內容如下
[c7.9-media]name=CentOS-$releasever - Mediabaseurl=file:///data/CentOS7.9/gpgcheck=0enabled=1gpgkey=file:///data/CentOS7.9/RPM-GPG-KEY-CentOS-7
清空yum緩存目錄yum clean all
建立yum元數據緩存yum makecache
查看本機yum repo 倉庫yum repolist然後安裝vsftp服務
安裝vsftpyum -y install vsftpd ftp
修改ftp配置文件 添加vi /etc/vsftpd/vsftpd.confanon_root=/data/CentOS7.9
啟動ftp systemctl start vsftpd systemctl enable vsftpd
測試ftp服務可用性 Trying ::1... Connected to localhost (::1). 220 (vsFTPd 3.0.2) Name (localhost:root): anonymous 331 Please specify the password. Password: 230 Login successful. Remote system type is UNIX. Using binary mode to transfer files. ftp> ls然後客戶端測試
客戶端配置本地yum源(ftp方式)配置yum源cd /etc/yum.repos.d/mkdir bakmv *.repo bak
編輯local.repo文件 tee CentOS-Local.repo << EOF[base]name=CentOS-Localbaseurl=ftp://192.168.160.131 gpgcheck=0enabled=1EOF
更新yum設置yum clean allyum makecacheyum repolist
測試配置yum -y install net-tools然後就是py的命令了：
