基于centos 7搭建本地yum源服务器及同步阿里源

1、系统环境

[root@yum-server ~]# cat /etc/centos-release
CentOS Linux release 7.3.1611 (Core) 

[root@yum-server ~]# uname -r
3.10.0-514.el7.x86_64

[root@yum-server ~]# ip a |awk 'NR==9{print $2}'|awk -F '/' '{print $1}'
10.0.7.190

[root@yum-server ~]# lsblk
NAME          MAJ:MIN RM  SIZE RO TYPE MOUNTPOINT
sr0            11:0    1   10G  0 rom  /mnt
sr1            11:1    1  484K  0 rom  
vda           253:0    0   20G  0 disk 
└─vda1        253:1    0   20G  0 part /
vdb           253:16   0  500G  0 disk 
└─yumvg-yumlv 252:0    0  500G  0 lvm  /yum  //yum仓库存储位置，一般实际生产中建议容量设置较大

2、配置环境

由于网络环境复杂，yum源服务有多种来源

base源、epel源、zabbix源、grafana源

源类型	版本	repoid	来源	使用者
base源-ISO	Centos-7	Centos-7-media.repo	CentOS-7-x86_64-Everything-1810.iso	服务端
		media.repo	http://10.0.7.190/repository/c7	客户端
base源-云	Centos-7	Centos-base-7.repo	http://mirrors.aliyun.com/repo/Centos-7.repo	服务端
		base-7.repo	http://10.0.7.190/repository/base-7	客户端
	Centos-6	Centos-base-6.repo	http://mirrors.aliyun.com/repo/Centos-6.repo	服务端
		base-6.repo	http://10.0.7.190/repository/base-6	客户端
epel源	Centos-7	Centos-epel-7.repo	http://mirrors.aliyun.com/repo/epel-7.repo	服务端
		epel-7.repo	http://10.0.7.190/repository/epel-7	客户端
	Centos-6	Centos-epel-6.repo	http://mirrors.aliyun.com/repo/epel-6.repo	服务端
		epel-6.repo	http://10.0.7.190/repository/epel-6	客户端
zabbix源	Centos-7	Centos-zabbix-7.repo	http://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/7/x86_64/	服务端
		zabbix-7.repo	http://10.0.7.190/repository/zabbix-7	客户端
	Centos-6	Centos-zabbix-6.repo	http://mirrors.aliyun.com/zabbix/zabbix/4.0/rhel/6/x86_64/	服务端
		epel-6.repo	http://10.0.7.190/repository/epel-6	客户端
grafana源	Centos-6/7	grafana.repo	https://mirrors.tuna.tsinghua.edu.cn/grafana/yum/rpm	服务端
		grafana.repo	http://10.0.7.190/repository/grafana	客户端

应用程序	作用	替代程序
httpd	baseurl	nginx/vsftp
yum-utils	repository的管理工具，提供reporsync服务
createrepo	编辑yum库工具
plugin-priorities	控制yum源更新优先级工具

3、搭建base-yum源-基于ISO镜像

3-1、备份并移除其他repo

[root@yum-server yum.repos.d]# cd 
[root@yum-server ~]# cd /etc/yum.repos.d/
[root@yum-server yum.repos.d]# tar czvf repo-bk.tar.gz CentOS-*
CentOS-Base.repo
CentOS-CR.repo
CentOS-Debuginfo.repo
CentOS-fasttrack.repo
CentOS-Media.repo
CentOS-Sources.repo
CentOS-Vault.repo
[root@yum-server yum.repos.d]# rm -rf *.repo
[root@yum-server yum.repos.d]# ls
repo-bk.tar.gz

3-2、挂载ISO镜像：

[root@yum-server yum.repos.d]# mount /dev/cdrom /mnt
mount: /dev/sr0 is write-protected, mounting read-only

3-3、配置ISO镜像源

区别于云base源，ISO本地源名称为media.repo

[root@yum-server yum.repos.d]# vim media.repo
[c7-media]
name=CentOS-$releasever-media
baseurl=file:///mnt
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

注：配置repo路径、关闭gbg校验、启用ISO镜像仓库

3-4、查看repolist

[root@yum-server yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
repo id                                                                    repo name                                                                         status
c7-media                                                                   CentOS-7-Media                                                                    10,019
repolist: 10,019

3-5、拷贝rpm包

[root@yum-server yum.repos.d]# mkdir -p /yum/repository/c7
[root@yum-server yum.repos.d]# cp -ra  /mnt/* /yum/repository/c7/  

或者使用reposync同步
[root@yum-server yum.repos.d]#reposync -r c7-media -p /yum/repository/c7/

3-6、创建索引:

[root@yum-server ~]# createrepo -po /yum/repository/c7 /yum/repository/c7

4、搭建base-7-yum源-基于云源

4-1、备份原有源：

[root@yum-server ~]# cd /etc/yum.repos.d/
[root@yum-server yum.repos.d]# mv CentOS-Media.repo CentOS-Media.repobak
[root@yum-server yum.repos.d]# ls
CentOS-Media.repobak repo-bk.tar.gz

4-2、下载云base-7源:

[root@yum-server yum.repos.d]# wget -O /etc/yum.repos.d/Centos-base-7.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@yum-server yum.repos.d]# ls
backup  Centos-base-7.repo

4-3、修改Centos-base-7.repo

将所有的源增加`-7`，$releasever更换为`7`
[root@yum-server yum.repos.d]# vim Centos-7-base.repo 
# CentOS-Base-7.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.
#

4-4、检验阿里云源是否正常:

[root@yum-server yum.repos.d]# yum repolist
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
 * base-7: mirrors.aliyun.com
 * extras-7: mirrors.aliyun.com
 * updates-7: mirrors.aliyun.com
repo id                                                             repo name                                                                                status

repolist: 12,225

4-5、根据源标识同步源到本地目录：

创建本地仓库目录:
[root@yum-server ~]# mkdir /yum/repository/
同步阿里base源到本地base目录:
[root@yum-server ~]# reposync -r base-7 -p /yum/repository/
注：不用担心没有创建相关目录，系统自动创建相关目录，并下载，时间较长请耐心等待。

4-6、创建索引:

[root@yum-server ~]# createrepo -po /yum/repository/base-7 /yum/repository/base-7

4-7、更新新的rpm包

[root@yum-server ~]# reposync -r base-7 -np /yum/repository/
注：时间同样较长，请耐心等待。

4-8、更新源数据:

[root@yum-server ~]# createrepo --update /yum/repository/base-7

4-9、创建定时任务脚本

[root@yum-server yum.repos.d]# vim /yum/script-reposync/yum-update-base-7.sh
#!/bin/bash
echo 'Updating Base Aliyum Source'
DATETIME=`date +%F_%T`
exec > /var/log/repo/update-base-7.repo_$DATETIME.log
     reposync -r base-7 -np /yum/repository/
if [ $? -eq 0 ];then
      createrepo --update /yum/repository/base-7
    echo "SUCESS: $DATETIME base.repo update successful"
  else
    echo "ERROR: $DATETIME base.repo update failed"
fi

4-10、将脚本加入到定时任务中

[root@yum-server script-reposync]# crontab -e
# Updating Aliyum Source
00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==3{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-base-7.sh
每月第一个周六的06点更新阿里云base yum源

5、搭建base-6-yum源-基于云源

5-1、备份原有源：

[root@yum-server ~]# cd /etc/yum.repos.d/
[root@yum-server yum.repos.d]# mv CentOS-Media.repo CentOS-Media.repobak
[root@yum-server yum.repos.d]# ls
CentOS-Media.repobak repo-bk.tar.gz

5-2、下载云base-6源:

[root@yum-server yum.repos.d]# wget -O /etc/yum.repos.d/Centos-base-6.repo http://mirrors.aliyun.com/repo/Centos-6.repo
[root@yum-server yum.repos.d]# ls
backup  Centos-base-7.repo

5-3、修改Centos-base-6.repo

将所有的源增加`-6`，$releasever更换为`6`
[root@yum-server yum.repos.d]# vim Centos-base-6.repo 
# CentOS-Base-6.repo
#
# The mirror system uses the connecting IP address of the client and the

[root@yum-server yum.repos.d]# ls
CentOS-Media.repobak  Centos-epel-6.repo  repo-bk.tar.gz

7-3、修改Centos-epel-6.repo

将所有的源增加`-6`
[root@yum-server yum.repos.d]# vim Centos-epel-6.repo 
[epel-6]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=http://mirrors.aliyun.com/epel/6/$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6

[epel-debuginfo-6]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
baseurl=http://mirrors.aliyun.com/epel/6/$basearch/debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=0

[epel-source-6]

baseurl=http://mirrors.aliyun.com/epel/6/SRPMS
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=0
~

注：时间同样较长，请耐心等待。

7-8、更新源数据:

[root@yum-server ~]# createrepo --update /yum/repository/epel-6

7-9、创建定时任务脚本

[root@yum-server yum.repos.d]# vim /yum/script-reposync/yum-update-epel-6.sh
#!/bin/bash
echo 'Updating Epel Aliyum Source'
DATETIME=`date +%F_%T`
exec > /var/log/repo/update-epel-6.repo_$DATETIME.log
     reposync -r epel-6 -np /yum/repository/
if [ $? -eq 0 ];then
      createrepo --update /yum/repository/epel-6
    echo "SUCESS: $DATETIME epel.repo update successful"
  else
    echo "ERROR: $DATETIME epel.repo update failed"
fi

7-10、将脚本加入到定时任务中

[root@yum-server script-reposync]# crontab -e
# Updating Aliyum Source
00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==4{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-epel-6.sh

13、总结

yum源服务器搭建根据来源不同，有多种方式，以上述实验为例，搭建步骤如下：

1. 规划好yum仓库存储容量(/yum/repository/，500G)
2. 采用国内源(阿里云、华为云、各大高校镜像库等)
3. 光盘镜像采用everything，确保rpm包尽可能完整
4. centos6和centos7采用同一台服务器部署时，注意更改base.repo文件中`$releasever`变量
5. 根据来源准备服务器端repo配置文件(repo编写方式大同小异，除epel源、base源外其他的均需手动编写配置)
6. 对外提供服务可采用web(apache、nginx)、ftp(vsftp)等方式，注意服务器安全，尽可能开启防火墙，通过放行服务端口策略确保网络安全
7. 其他yum源更新脚本可根据实际情况参考编写

服务器端计划任务：

[root@yum-server yum.repos.d]# crontab -l
# Updating Aliyum Source
#00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==3{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-epel.sh
#00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==4{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-zabbix.sh
#00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==5{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-base.sh
#00 06 * * 6 [ $(date +%d) -eq $(cal | awk 'NR==6{print $NF}') ] && /bin/bash /yum/script-reposync/yum-update-grafana.sh

00 00 25 * * /bin/bash /yum/script-reposync/yum-update-base-7.sh
00 00 26 * * /bin/bash /yum/script-reposync/yum-update-base-6.sh
00 01 * * * /bin/bash /yum/script-reposync/yum-update-epel-7.sh
00 02 * * * /bin/bash /yum/script-reposync/yum-update-epel-6.sh
00 04 * * * /bin/bash /yum/script-reposync/yum-update-zabbix-7.sh
00 05 * * * /bin/bash /yum/script-reposync/yum-update-zabbix-6.sh
00 06 * * * /bin/bash /yum/script-reposync/yum-update-grafana.sh

服务端repo：

[root@yum-server yum.repos.d]# ls
