repo的路径不要放到root下，放到/usr/share/nginx/下，要不没权限
Centos 7建立本地内网源
一、环境
二、先配置163base源及阿里epel源
三、建立本地仓库localbase、localepel
四、通过nginx将发布源站
五、客户端使用192.168.1.111的base及epel源
建立一台YUM源服务器，同步163base源及阿里epel源，通过nginx发布出去，为企业PC提供yum服务。
一、环境
服务端：
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@localhost ~]# ifconfig|grep inet
inet 192.168.1.111 netmask 255.255.255.0 broadcast 192.168.1.255

客户端PC：
[root@localhost ~]# cat /etc/redhat-release
CentOS Linux release 7.7.1908 (Core)
[root@localhost ~]# ifconfig|grep inet
inet 192.168.1.107 netmask 255.255.255.0 broadcast 192.168.1.255

二、先配置163base源及阿里epel源
安装yum支持环境
[root@localhost ~]# yum install createrepo yum-utils –y
1
备份base源文件
[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo{,.bakup}
1
下载reop文件
163base源
[root@localhost ~]# wget -P /etc/yum.repos.d/ http://mirrors.163.com/.help/CentOS7-Base-163.repo
阿里epel源
[root@localhost ~]# wget -O /etc/yum.repos.d/epel.repo https://mirrors.aliyun.com/repo/epel-7.repo

清缓存
[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache
1

3
查看源列表
[root@localhost ~]# yum repolist
1
三、建立本地仓库localbase、localepel
新建仓库目录localbase、localepel
[root@localhost ~]# mkdir -p /data/localrepo/localbase
[root@localhost ~]# mkdir -p /data/localrepo/localepel
1
2
3
同步base源
[root@localhost ~]# reposync -r base -p /data/localrepo/localbase
1
同步epel源
[root@localhost ~]# reposync -r epel -p /data/localrepo/localepel
1
创建仓库repodata目录，每次有新包都得运行此命令加载一次
base
[root@localhost ~]# createrepo /data/localrepo/localbase
Spawning worker 0 with 5035 pkgs
Spawning worker 1 with 5035 pkgs

下载base源gpgkey文件（epel gpgkey文件不用下载）
保存至/data/localrepo/localbase/
[root@localhost~]#wget -P /data/localrepo/localbase/ http://mirrors.163.com/centos/7/os/x86_64/RPM-GPG-KEY-CentOS-7

备份base与epel源配置文件
[root@localhost ~]# mv /etc/yum.repos.d/CentOS7-Base-163.repo{,.bakup}
[root@localhost ~]# mv /etc/yum.repos.d/epel.repo{,.bakup}
1

新建base与epel本地源配置文件
[root@localhost ~]# vim /etc/yum.repos.d/localbase.repo
[base]
name=centos7 local base_163
baseurl=file:///data/localrepo/localbase/
gpgcheck=1
gpgkey=file:///data/localrepo/localbase/RPM-GPG-KEY-CentOS-7

[root@localhost ~]# vim /etc/yum.repos.d/localepel.repo
[epel]

查看仓库列表yum repolist
四、通过nginx将发布源站
安装nginx
[root@localhost ~]# yum install nginx -y
1
编译nginx配置文件
[root@localhost ~]# vim /etc/nginx/nginx.conf
42 autoindex on; #开启目录访问功能
43 root /data/localrepo; #路径

[root@localhost ~]# systemctl restart nginx 启动nginx
[root@localhost ~]# systemctl stop firewalld 临时关闭防火墙,也可以开启端口，这里就不说明了
[root@localhost ~]# setenforce 0 关闭selinux
[root@localhost ~]# vim /etc/selinux/config
SELINUX=disabled

打开浏览器输入IP即可
可以看到base与epel源，点击进入，里面也有文件，与163官网类似
五、客户端使用192.168.1.111的base及epel源
[root@localhost ~]# vim /etc/yum.repos.d/localbase.repo
[base]
name=centos7 local base_163
baseurl=http://192.168.1.111/localbase/
gpgcheck=1
gpgkey=http://192.168.1.111/localbase/RPM-GPG-KEY-CentOS-7

将旧的base改名备份
[root@localhost ~]# mv /etc/yum.repos.d/CentOS-Base.repo{,.bakup}

[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache
[root@localhost ~]# yum repolist
