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 Date: Sun, 05 Jul 2020 09:48:05 GMT Content-Type: text/html Content-Length: 4833 Last-Modified: Fri, 16 May 2014 15:12:48 GMT Connection: keep-alive ETag: "53762af0-12e1" Accept-Ranges: bytes
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/ 9.0G Aliyun/version_7/64bit/base/Packages 9.0G Aliyun/version_7/64bit/base 616M Aliyun/version_7/64bit/extras/Packages 616M Aliyun/version_7/64bit/extras 3.6G Aliyun/version_7/64bit/updates/Packages 3.6G Aliyun/version_7/64bit/updates 14G Aliyun/version_7/64bit 14G Aliyun/version_7 9.0G Aliyun/version_6/64bit/base/Packages 9.0G Aliyun/version_6/64bit/base 616M Aliyun/version_6/64bit/extras/Packages 616M Aliyun/version_6/64bit/extras 3.6G Aliyun/version_6/64bit/updates/Packages 3.6G Aliyun/version_6/64bit/updates 14G Aliyun/version_6/64bit 14G Aliyun/version_6 27G 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 Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7/64bit/extras/Packages/ Spawning worker 0 with 397 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_7/64bit/updates/Packages/ Spawning worker 0 with 884 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6/64bit/base/Packages/ Spawning worker 0 with 10070 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6/64bit/updates/Packages/ Spawning worker 0 with 884 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@yum-server ~]# createrepo -p /usr/share/nginx/html/CentOS-YUM/Aliyun/version_6/64bit/extras/Packages/ Spawning worker 0 with 397 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete[root@yum-server ~]# tree -d /usr/share/nginx/html/CentOS-YUM/Aliyun/ # 建仓完成后，会自动生成一个repodata目录 /usr/share/nginx/html/CentOS-YUM/Aliyun/ ├── version_6 │ └── 64bit │ ├── base │ │ └── Packages │ │ └── repodata │ ├── extras │ │ └── Packages │ │ └── repodata │ └── updates │ └── Packages │ └── repodata └── version_7 └── 64bit ├── base │ └── Packages │ └── repodata ├── extras │ └── Packages │ └── repodata └── updates └── Packages └── repodata 22 directories
'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 [Aliyun_7_base] name=source_from_localserver baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_7/64bit/base/Packages gpgcheck=0 enable=1 [Aliyun_7_extras] name=source_from_localserver baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_7/64bit/extras/Packages gpgcheck=0 enable=1 [Aliyun_7_updates] name=source_from_localserver baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_7/64bit/updates/Packages gpgcheck=0 enable=1 # [Aliyun_6_base] # name=source_from_localserver # baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_6/64bit/base/Packages # gpgcheck=0 # enable=1 # # [Aliyun_6_extras] # name=source_from_localserver # baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_6/64bit/extras/Packages # gpgcheck=0 # enable=1 # # [Aliyun_6_updates] # name=source_from_localserver # baseurl=http://192.168.57.133/CentOS-YUM/Aliyun/version_6/64bit/updates/Packages # gpgcheck=0 # enable=1 [root@localhost yum.repos.d]# yum clean all [root@localhost yum.repos.d]# yum makecache
