CentOS7下的YUM源服务器搭建

Posted 2020-10-26

1.目标要求

2.安装server端

3.配置server端

4.配置当前系统yum来源repo文件

5.进行同步脚本的创建并执行同步

1.目标要求

• yum源服务器要自动更新自身源

• 使用CentOS官方标准源version6和version7的两个版本保持更新

• 客户端可以直接使用源

国内速度比较快的源服务器

http://mirrors.aliyun.com/

http://centos.ustc.edu.cn/centos/

http://mirrors.163.com

2.安装server端

• 关闭防火墙和selinux

[[email protected] ~]# vim /etc/hostname

yumserver

[[email protected] ~]# hostnamectl status

Static hostname: yumserver         Icon name: computer-vm           Chassis: vm        Machine ID: 06490d1675224b898ac71b9ed141cb39           Boot ID: 2a568995acaa4bb2928bdb8e6330ddd3    Virtualization: vmware  Operating System: CentOS Linux 7 (Core)       CPE OS Name: cpe:/o:centos:centos:7            Kernel: Linux 3.10.0-327.el7.x86_64      Architecture: x86-64

[[email protected] ~]# su - root [[email protected] ~]# systemctl stop firewalld.service [[email protected] ~]# systemctl disable firewalld.service

Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service. Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.

[[email protected] ~]# sed -i "s/SELINUX=enforcing/SELINUX=disabled/" /etc/selinux/config [[email protected] ~]# setenforce 0

• 安装nginx软件包

[[email protected] ~]# yum -y install epel-release [[email protected] ~]# yum -y install nginx

[[email protected] ~]# find / -name nginx.conf

/etc/nginx/nginx.conf

[[email protected] ~]# vim /etc/nginx/nginx.conf

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大小； autoindex_localtime on;                  #表示显示更改时间，以点前系统的时间为准； error_page 404 /404.html;

• 安装createrepo软件包

安装建yum源仓库的工具，可以用来建立yum仓库

[[email protected] ~]# yum -y install createrepo yum-utils

Installed:  createrepo.noarch 0:0.9.9-28.el7                                                                                                                                                                       Dependency Installed:  deltarpm.x86_64 0:3.6-3.el7                                 libxml2-python.x86_64 0:2.9.1-6.el7_2.3                                 python-deltarpm.x86_64 0:3.6-3.el7                                 Dependency Updated:  libxml2.x86_64 0:2.9.1-6.el7_2.3                                                                                                                                                                       Complete!

• 安装yum-plugin-priorities软件包

安装控制yum源更新优先级工具，这个工具可以用来控制进行yum源检索的先后顺序，建议用在client端。

[[email protected] ~]# yum -y install yum-plugin-priorities

Installed:  yum-plugin-priorities.noarch 0:1.1.31-42.el7                                                                                                                                                           Complete!

3.配置server端

[[email protected] /]# find / -name html

/usr/share/doc/pam-1.1.8/html /usr/share/nginx/html

[[email protected] ~]# mkdir -p /usr/share/nginx/html/CentOS-Yum/CentOS6/x86_64 [[email protected] ~]# mkdir -p /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64 [[email protected] ~]# chmod -R +x /usr/share/nginx/html [[email protected] ~]# vim /usr/share/nginx/html/index.html

</head>    <body>        <h1>Welcome to <strong>nginx</strong> on Fedora!</h1>        <div class="content">            <p>This page is used to test the proper operation of the            <strong>nginx</strong> HTTP server after it has been            installed.

[[email protected] ~]# service nginx restart

4.配置当前系统yum来源repo文件

备份现有CentOS-Base.repo文件

[[email protected] ~]# cp -p /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.back [[email protected] ~]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo [[email protected] ~]# ll /etc/yum.repos.d/CentOS-Base.repo

下载并查看CentOS-Base.repo文件

[[email protected] ~]# vim /etc/yum.repos.d/CentOS-Base.repo

# CentOS-Base.repo # # The mirror system uses the connecting IP address of the client and the # update status of each mirror to pick mirrors that are updated to and # geographically close to the client.  You should use this for CentOS updates # unless you are manually picking other mirrors. # # If the mirrorlist= does not work for you, as a fall back you can try the # remarked out baseurl= line instead. # # [base] name=CentOS-$releasever - Base - mirrors.aliyun.com failovermethod=priority baseurl=http://mirrors.aliyun.com/centos/$releasever/os/$basearch/        http://mirrors.aliyuncs.com/centos/$releasever/os/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os gpgcheck=1 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 #released updates [updates] name=CentOS-$releasever - Updates - mirrors.aliyun.com failovermethod=priority baseurl=http://mirrors.aliyun.com/centos/$releasever/updates/$basearch/        http://mirrors.aliyuncs.com/centos/$releasever/updates/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates gpgcheck=1 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7 #additional packages that may be useful [extras] name=CentOS-$releasever - Extras - mirrors.aliyun.com failovermethod=priority baseurl=http://mirrors.aliyun.com/centos/$releasever/extras/$basearch/        http://mirrors.aliyuncs.com/centos/$releasever/extras/$basearch/ #mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras gpgcheck=1 gpgkey=http://mirrors.aliyun.com/centos/RPM-GPG-KEY-CentOS-7

目前只能是CentOS7的版本的所有yum源，如果需要同步6版本的yum源，将CentOS-Base.repo文件内的7版本号更改为6就可以了。将$releasever替换为6，将$basearch替换为x86_64,将版本7改为6

:1,$s/$releasever/6/g

5.进行同步脚本的创建并执行同步

[[email protected] ~]# reposync –p /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/ [[email protected] ~]# ls

anaconda-ks.cfg  base  extras  updates

[[email protected] ~]# mv base/ /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/ [[email protected] ~]# mv extras/ /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/ [[email protected] ~]# mv updates/ /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/ [[email protected] ~]# cd /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/ [[email protected] x86_64]# ls

base  extras  updates

[[email protected] ~]# createrepo -p /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/base/Packages/

Spawning worker 0 with 4796 pkgs Spawning worker 1 with 4795 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete

[[email protected] ~]# createrepo -p /usr/share/nginx/html/CentOS-Yum/CentOS7/x86_64/extras/Packages/

Spawning worker 0 with 770 pkgs Spawning worker 1 with 770 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete

使用同样方法，同步centos6软件包。

将$releasever替换为6，将$basearch替换为x86_64,将版本7改为6 :1,$s/$releasever/6/g
