构建企业YUM仓库

1、服务端

1）安装ftp服务

[root@VM_0_3_centos ~]# systemctl stop firwalld
Failed to stop firwalld.service: Unit firwalld.service not loaded.
[root@VM_0_3_centos ~]# setenforce 0
setenforce: SELinux is disabled
[root@VM_0_3_centos ~]# yum -y install vsftpd

[root@VM_0_3_centos ~]# systemctl start vsftpd
[root@VM_0_3_centos ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.

在客户端打开网页验证ftp运行正常：

找到ftp资源目录，新建文件夹：

[root@VM_0_3_centos ~]# rpm -ql vsftpd |grep pub
/var/ftp/pub
[root@VM_0_3_centos ~]# mkdir /var/ftp/centos7

在客户端刷新再次验证：

2）下载rpm资源包：

[root@VM_0_3_centos ~]# cd /var/ftp/centos7/
[root@VM_0_3_centos centos7]# curl http://mirrors.163.com/centos/7/updates/x86_64/Packages/ | awk -F '[">]+' '{print "wget http://mirrors.163.com/centos/7/updates/x86_64/Packages/"$2}'|bash

下载完成后，再次在客户端刷新可以看到centos7目录内已经有rpm资源了。

3）构建repodata仓库

在客户端重新刷新，可以看到生成了repodata目录。

2、客户端

1）配置yum源

[root@VM_0_4_centos centos7]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Epel.repo
[root@VM_0_4_centos centos7]# gzip /etc/yum.repos.d/*
[root@VM_0_4_centos centos7]# ls /etc/yum.repos.d/
CentOS-Base.repo.gz  CentOS-Epel.repo.gz
[root@VM_0_4_centos centos7]# vim /etc/yum.repos.d/centos7.repo
[ftp]
name=centos7.ftp
baseurl=ftp://129.*.*.*/centos7
gpgcheck=0
enabled=1

2）测试验证

[root@VM_0_4_centos centos7]# yum install -y vim-enhanced   ##可以看到安装来源于FTP
