背景:
有这样的需求,测试环境网段不能上网,但是测试环境centos安装软件包每一台都配置本地yum源很麻烦,也缺少第三方yum源,特此在内网搭建一台yum源服务器满足这一需求,同时防火墙层面只允许此yum源服务器每周日晚限时联网同步阿里云的yum源.
一.yum源服务器的系统环境,最小化安装
[root@yumserver ~]# cat /etc/redhat-release CentOS Linux release 7.9.2009 (Core)
yum源服务器地址 10.8.98.222
放开系统防火墙,关闭selinux
[root@yumserver ~]# firewall-cmd --add-port=80/tcp --permanent success [root@yumserver ~]# firewall-cmd --reload success
[root@yumserver ~]# cat /etc/selinux/config # This file controls the state of SELinux on the system. # SELINUX= can take one of these three values: # enforcing - SELinux security policy is enforced. # permissive - SELinux prints warnings instead of enforcing. # disabled - No SELinux policy is loaded. SELINUX=disabled # SELINUXTYPE= can take one of three values: # targeted - Targeted processes are protected, # minimum - Modification of targeted policy. Only selected processes are protected. # mls - Multi Level Security protection. SELINUXTYPE=targeted
二.添加阿里云yum源并检查
备份好原系统的repo
[root@yumserver yum.repos.d]# pwd /etc/yum.repos.d [root@yumserver yum.repos.d]# mkdir backup [root@yumserver yum.repos.d]# mv *.repo backup/
curl -o /etc/yum.repos.d/CentOS-Base.repo https:999999//mirrors.aliyun.com/repo/Centos-7.repo curl -o /etc/yum.repos.d/epel.repo http:999999//mirrors.aliyun.com/repo/epel-7.repo yum makecache yum repolist
去掉999999
三.安装相关软件
yum install -y wget make cmake gcc gcc-c++ pcre-devel zlib-devel openssl openssl-devel httpd yum-utils createrepo
标注:
yum-utils:reposync同步工具
createrepo:编辑yum库工具
httpd:通过Apache软件提供web服务,也可以使用nginx
四、同步阿里云yum源软件包到本地服务器指定目录/mirror(自定义目录)
mkdir -p /mirror chown -R apache:apache /mirror chmod -R 755 /mirror ###参数-n指下载最新软件包,-p指定目录,指定本地的源--repoid(如果不指定就同步本地服务器所有的源),下载过程比较久 reposync -n --repoid=extras --repoid=updates --repoid=base --repoid=epel -p /mirror [root@yumserver ~]# du -sh /mirror/* 9.0G /mirror/base 16G /mirror/epel 321M /mirror/extras 2.2G /mirror/updates
五 、创建仓库索引
createrepo -po /mirror/base/ /mirror/base/ createrepo -po /mirror/extras/ /mirror/extras/ createrepo -po /mirror/updates/ /mirror/updates/ createrepo -po /mirror/epel/ /mirror/epel/
六 、更新数据源
createrepo --update /mirror/base/ createrepo --update /mirror/extras/ createrepo --update /mirror/updates/ createrepo --update /mirror/epel/
七、启动并配置Apache服务
systemctl start httpd systemctl enable httpd systemctl status httpd [root@yumserver ~]# vim /etc/httpd/conf/httpd.conf DocumentRoot "/mirror/"Options Indexes FollowSymLinks AllowOverride None Order allow,deny Allow from all Require all granted
###修改Apache默认首页index.html,直接复制粘贴执行
cat << EOF > /usr/share/httpd/noindex/index.htmlCentOS 7 镜像 简介
CentOS,是基于 Red Hat Linux 提供的可自由使用源代码的企业级 Linux 发行版本。
CentOS 7 配置内部YUM源
1、备份
mkdir /etc/yum.repos.d/backup mv /etc/yum.repos.d/*.repo /etc/yum.repos.d/backup/
2、下载新的 CentOS-Base.repo 到 /etc/yum.repos.d/
curl -o /etc/yum.repos.d/CentOS-Base.repo xxxx://x.x.x.x/repo/CentOS-Base.repo
3、运行 yum makecache 生成缓存
4、运行 yum repolist 查看已经生成缓存
EOF
注意:上面
xxxx://x.x.x.x/
更改为自己对应的
我这里为http : // 10.8.98.222 /
八、编写yum源客户端配置文件
[root@yumserver repo]# cat /mirror/repo/CentOS-Base.repo [base] name=CentOS- - Base - 10.8.98.222 failovermethod=priority baseurl=http://*******/base/ enable=1 gpgcheck=0 #released updates [updates] name=CentOS- - Updates - 10.8.98.222 failovermethod=priority baseurl=http://*******/updates/ enable=1 gpgcheck=0 #additional packages that may be useful [extras] name=CentOS- - Extras - 10.8.98.222 failovermethod=priority baseurl=http://*******/extras/ enable=1 gpgcheck=0 #additional packages that may be useful [epel] name=CentOS- - Epel - 10.8.98.222 failovermethod=priority baseurl=http://*******/epel/ enable=1 gpgcheck=0 [root@yumserver repo]#
*******此处为自己的ip
九、客户端配置yum源
用户可以浏览器访问10.8.98.222查看配置客户端yum源的方法
curl -o /etc/yum.repos.d/CentOS-Base.repo http:/ /10.8.98.222/repo/CentOS-Base.repo yum makecache
十 、设置定时同步yum源的任务
[root@yumserver ~]# cat /mirror/script/centos_yum_update.sh
#!/bin/bash echo 'Updating Aliyum Source' DATETIME=`date +%F_%T` exec > /var/log/aliyumrepo_$DATETIME.log reposync -np /mirror if [ $? -eq 0 ];then createrepo --update /mirror/base createrepo --update /mirror/extras createrepo --update /mirror/updates createrepo --update /mirror/epel echo "SUCESS: $DATETIME aliyum_yum update successful" else echo "ERROR: $DATETIME aliyum_yum update failed" fi
添加定时任务,每周一凌晨1点执行
[root@yumserver ~]# crontab -l 0 1 * * 1 /bin/bash /mirror/script/centos_yum_update.sh
