Linux 部署 YUM 仓库

本篇主要写了怎么搭建自定义的YUM源，在一个拥有大量本地网络的主机环境中，可以减少对外网的依赖。

Server

安装 vsftp 包

[root@server ~]# yum install vsftpd -y

添加相关资源包

• 创建需要存放的目录

[root@server ~]# mkdir /var/ftp/centos7 /var/ftp/others
[root@server ~]# ls /var/ftp/
centos7  others  pub

• 拷贝镜像文件内容至相关目录

[root@server ~]# mount /dev/cdrom /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[root@server ~]# cp -r /mnt/* /var/ftp/centos7/

• 给others目录创建repodata

[root@server ~]# createrepo -g /var/ftp/centos7/repodata/repomd.xml /var/ftp/others/

• 检查文件是否齐全

[root@server ~]# ls /var/ftp/centos7/
CentOS_BuildTag  EFI  EULA  GPL  images  isolinux  LiveOS  Packages  repodata  RPM-GPG-KEY-CentOS-7  RPM-GPG-KEY-CentOS-Testing-7  TRANS.TBL

[root@server ~]# ls /var/ftp/others/
repodata

开启服务

[root@server ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
[root@server ~]# systemctl start vsftpd
[root@server ~]# netstat -ntuap | grep vsftpd
tcp6       0      0 :::21                   :::*                    LISTEN      35971/vsftpd        

关闭防火墙

[root@server ~]# systemctl stop firewalld
[root@server ~]# setenforce 0

Client

安装 ftp 包

[root@client ~]# yum install ftp -y

匿名登录查看

[root@client ~]# ftp 192.168.28.128

编辑 YUM 源配置文件

• 备份已有yum源

[root@client ~]# cd /etc/yum.repos.d/
[root@client yum.repos.d]# mkdir bak
[root@client yum.repos.d]# mv *.repo bak/

• 编辑自定义yum源

[root@client yum.repos.d]# vim ftp.repo
[base]
name=centos7.Packages
baseurl=ftp://192.168.28.128/centos7/
enabled=1
gpgcheck=1
gpgkey=ftp://192.168.28.128/centos7/RPM-GPG-KEY-CentOS-7

[others]
name=others.Packages
baseurl=ftp://192.168.28.128/others/
enabled=1
gpgcheck=0
