构建企业 YUM仓库

本地光盘提供基础软件包Base
yum缓存提供update软件包
yum缓存提供常用软件包: nginx, zabbix, docker, saltstack

环境准备

系统	IP	角色	主机名
centos7.4_x86_64	192.168.69.112	yum仓库服务端	yum_server_69_112
centos7.4_x86_64	192.168.69.113	yum仓库客户端	yum_client_69_113

服务端配置

1.基础环境准备

//关闭防火墙
[[email protected]_server_69_112 ~]# systemctl stop firewalld

//临时关闭selinux
[[email protected]_server_69_112 ~]# setenforce 0

//安装ftp服务,启动并加入开机启动
[[email protected]_server_69_112 ~]# yum -y install vsftpd 
[[email protected]_server_69_112 ~]# systemctl start vsftpd 
[[email protected]_server_69_112 ~]# systemctl enable vsftpd

//开启yum缓存功能
[[email protected]_server_69_112 ~]# vim /etc/yum.conf
[main] cachedir=/var/cache/yum/$basearch/$releasever 
keepcache=1
[[email protected]_server_69_112 ~]# yum clean all

2.提供基础base源

[[email protected]_server_69_112 ~]# mkdir /var/ftp/centos75
[[email protected]_server_69_112 ~]# mount /dev/cdrom /mnt
[[email protected]_server_69_112 ~]# cp -rp  /mnt/Packages/*.rpm /var/ftp/centos75

3.提供第三方源

[[email protected]_server_69_112 ~]# mkdir /var/ftp/ops
[[email protected]_server_69_112 ~]# yum -y install nginx docker

//复制已缓存的 Nginx docker 及依赖包 到自定义 YUM 仓库目录中
[[email protected]_server_69_112 ~]# find /var/cache/yum/x86_64/7/ -iname "*.rpm" -exec cp -rf {} /var/ftp/ops ;

4.安装createrepo并创建 reopdata仓库

//安装createrepo
[[email protected]_server_69_112 ~]# yum -y install createrepo
//生成仓库信息
[[email protected]_server_69_112 ~]# createrepo /var/ftp/ops
[[email protected]_server_69_112 ~]# createrepo /var/ftp/centos75
//注意: 如果此仓库每次新增软件则需要重新生成一次

客户端使用yum源

1.配置并使用base基础源

[[email protected]_client_69_113 ~]# gzip /etc/yum.repos.d/*
[[email protected]_client_69_113 ~]# vim /etc/yum.repos.d/centos7.repo 
[centos75]
name=centos74_base
baseurl=ftp://172.16.1.250/centos75
gpgcheck=0

2.客户端指向本地ops源

[[email protected]_client_69_113 ~]# vim /etc/yum.repos.d/ops.repo 
[ops]
name=local ftpserver
baseurl=ftp://172.16.1.250/ops
gpgcheck=0

yum clean all
yum makecache

yum 仓库安装软件报错
ftp://172.16.1.250/centos75/repodata/repomd.xml: [Errno 14] FTP Error 550 - Server denied you to change to the given directory
拒绝更改到指定的目录

解决
//安装createrepo
[[email protected]_server_69_112 ~]# yum -y install createrepo
//生成仓库信息
[[email protected]_server_69_112 ~]# createrepo /var/ftp/ccentos75
//注意: 如果此仓 库每次新增软件则需要重新生成一次
