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
1、配置服务器端yum
1.1、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 ~]# yum -y install createrepo yum-utils # 安装repository管理工具
1.2、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
HTTP/1.1 200 OK
Server: nginx/1.16.1

1.2.1、配置nginx页面目录
[root@yum-server nginx]# cd /usr/share/nginx/html/
[root@yum-server html]# mkdir -p CentOS-YUM/Aliyun/{version_6,version_7}/64bit
[root@yum-server html]# tree /usr/share/nginx/html/CentOS-YUM/
/usr/share/nginx/html/CentOS-YUM/
└── Aliyun
├── version_6
│ └── 64bit
└── version_7
└── 64bit
5 directories, 0 files
[root@yum-server html]# cd CentOS-YUM/
[root@yum-server CentOS-YUM]# vim index.html
<p style="font-weight:bolder;color:green;font-size:30px;">ALL of the packages in the below:</p>
<br/>
<a href="http://192.168.57.133/CentOS-YUM/Aliyun">version_6</a><br/>
These packagers using for Centos 6<br/>
<a href="http://192.168.57.133/CentOS-YUM/Aliyun">version_7</a><br/>
These packagers using for Centos 7<br/>
<p style="font-weight:bolder;color:red;font-size:18px;">Please replace the file and fill in the f ollowing content:</p>
<p style="font-weight:bolder;color:blue;font-size:15px;">Way: /etc/yum.repos.d/CentOS-Base.repo</ p>
1.3、替换yum源文件
# 备份原来的官方yum源
[root@yum-server CentOS-YUM]# cd /etc/yum.repos.d/
[root@yum-server yum.repos.d]# mv ./* /tmp/
[root@yum-server yum.repos.d]# wget -O /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-7.repo # 下载aliyun的centos7的yum源
[root@yum-server yum.repos.d]# vim yum.reposync.sh # 同步脚本
#!/usr/bin/bash
reposync -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7/64bit/
# 同步/etc/yum.repos.d/CentOS-Base.repo内的rpm包
/usr/bin/sed -i "s/7/6/g" /etc/yum.repos.d/CentOS-Base.repo
# 将CentOS-Base.repo内的7改成6,后续同步centos6的rpm包使用
reposync -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6/64bit/
# 同步/etc/yum.repos.d/CentOS-Base.repo内的rpm包(此时是centos6的包)
/usr/bin/sed -i "s/6/7/g" /etc/yum.repos.d/CentOS-Base.repo
# 重新将CentOS-Base.repo内的6改回成7,下次同步的时候,不会出错
[root@yum-server yum.repos.d]# chmod +x yum.reposync.sh # 要给执行权限
[root@yum-server yum.repos.d]# ll
total 8
-rw-r--r-- 1 root root 2523 Jun 16 2018 CentOS-Base.repo
-rwxr-xr-x 1 root root 303 Jul 5 19:02 yum.reposync.sh
[root@yum-server yum.repos.d]# sh yum.reposync.sh
# 等待同步完成
# 同步完成,查看文件大小,合计27G
[root@yum-server CentOS-YUM]# du -ch Aliyun/

27G total
1.4、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
[root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7/64bit/base/Packages/
Spawning worker 0 with 10070 pkgs
Workers Finished

'可以写一个更新yum源的脚本,然后写一个计划任务,定期更新yum源(reposync -np 就是更新新的rpm包)
#!/usr/bin/bash
reposync -np /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7/64bit/
echo "centos7 is sync complate"
/usr/bin/sed -i "s/7/6/g" /etc/yum.repos.d/CentOS-Base.repo`
reposync -np /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6/64bit/
echo "centos6 is sync complate"
/usr/bin/sed -i "s/6/7/g" /etc/yum.repos.d/CentOS-Base.repo
2、配置客户端yum
# 备份原来的yum源
[root@localhost ~]# cd /etc/yum.repos.d/
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo epel-testing.repo
CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo epel.repo
[root@localhost yum.repos.d]# mkdir back
[root@localhost yum.repos.d]# mv *.repo back/
[root@localhost yum.repos.d]# ls
back
[root@localhost yum.repos.d]# vim CentOS-Base.repo # 需要6,就使用6,需要7,就使用7,也可以使用yum-plugin-priorities工具来控制优先级,加上priority=1(2|3|4都可以)来控制优先级
