0x01 概述
环境准备：
CentOS7_A：YUM-SERVER，用来部署本地yum仓库。
ip：172.16.10.78
CentOS7_A：用来测试搭建YUM仓库是否生效。
ip：172.16.10.79

0x02 YUM-SERVER部署web服务
在yum-server机子上搭建一个web服务，开启目录索引

# 写入nginx repo
cat <<EOF > nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/\$releasever/\$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true

[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/\$releasever/\$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
module_hotfixes=true
EOF

# 更新索引，安装nginx
yum mackcache
yum install nginx -y
systemctl start nginx && systemctl enable nginx

# 把原来的默认nginx配置文件删掉
mv /etc/nginx/conf.d/default.conf /etc/nginx/conf.d/default.conf.bak
# 写入一个新的配置文件，/www/html/yumrepos开启目录访问
cat < /etc/nginx/conf.d/yumrepos.conf
server {
    listen 80;
    server_name _;

    root /www/html/yumrepos;
    index index.html index.htm index.php;
    autoindex on;
}
EOF
# 重载nginx配置
nginx -s reload

# 测试web服务是否生效
myluzh@myluzhMacBookPro ~ % curl -I http://172.16.10.78/

0x03 同步远程软件包到本地YUM-SERVER

# 安装yum源仓库需要用到的软件包
yum install -y yum-utils createrepo
# 同步repo中的软件包到本地
reposync -c /etc/yum.repos.d/CentOS-Base.repo -p /www/html/yumrepos
reposync -c /etc/yum.repos.d/nginx.repo -p /www/html/yumrepos
# 若要同步xxx.repo中指定块[section]中的rpm包，可以指定名称同步
reposync -n --repoid=base --repoid=updates -p /www/html/yumrepos
reposync -n --repoid=nginx-stable -p /www/html/yumrepos
# 同步完成后需要创建yum仓库信息
createrepo -v /www/html/yumrepos/nginx-stable

例子： 这里我我们尝试同步nginx.repo的[nginx-stable]到 /www/html/yumrepos。然后通过createrrepo命令创建yum仓库信息，完成后会生成一个repodata目录。

# 同步rpm包到本地
[root@yum-server yum.repos.d]# reposync -n --repoid=nginx-stable -p /www/html/yumrepos
# 看到/www/html/yumrepos/已经有rpm包了，同步完了，并且repodata目录也在了。
[root@yum-server yum.repos.d]# tree /www/html/yumrepos/
/www/html/yumrepos/
