CentOS7下的YUM源服务器搭建
注意：环境要求
`阿里源的centos6和centos7各14G不到，注意磁盘空间`
'环境准备，修改hostname，关闭防火墙，disabled selinux'
[root@localhost ~]# hostnamectl set-hostname --static yum-server
[root@yum-server ~]# systemctl disable firewalld --now
[root@yum-server ~]# sed -i 's/^SELINUX=.*/SELINUX=disabled/' /etc/sysconfig/selinux
配置服务器端yum
安装yum源工具
[root@yum-server ~]# yum -y install epel-release.noarch # nginx需要epel源
[root@yum-server ~]# yum -y install nginx # 安装nginx
[root@yum-server ~]# createrepo yum-utils # 安装repository管理工具
配置nginx
[root@yum-server nginx]# cd /etc/nginx/
[root@yum-server nginx]# cp nginx.conf{,.bak} # 备份！备份！备份！
[root@yum-server nginx]# vim nginx.conf
server {
listen 80;
server_name localhost;
root /usr/share/nginx/html;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
# 在server段加入以下三段内容
autoindex on; # 表示：自动在index.html的索引打开
autoindex_exact_size on; # 表示：如果有文件，则显示文件的大小
autoindex_localtime on; # 表示：显示更改时间，以当前系统的时间为准
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
[root@yum-server nginx]# nginx -t # 检测一下nginx语法是否有错
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@yum-server nginx]# systemctl enable nginx.service --now # 启动nginx，设为开机自启
Created symlink from /etc/systemd/system/multi-user.target.wants/nginx.service to /usr/lib/systemd/system/nginx.service.
[root@yum-server nginx]# curl -I http://localhost # 访问本地，状态码返回200，服务正常

建立yum源仓库
'因为建仓最终的目的也是可供client来进行检索的，所以得每个Packages目录都要建成仓库，所以建仓的时候，目录指到最底层的Packages,而-np更新的时候只用指定到64bit的目录就可以了，否则会重复建立base、extras、updates三个目录进行下载
