CentOS7.3 創建本地YUM源和局域網YUM源
由於某某公司針對安全這一塊做的比較嚴謹，服務器全部都不可以連接外網。由於開發環境只有局域網，沒法使用網上的各種YUM源，來回拷貝rpm包安裝麻煩，還得解決依賴問題。想著在CentOS7.3搭建個本地/局域網YUM源，方便自己跟同事安裝軟件。
創建本地YUM源
環境：
[[email protected] ~]# cat /etc/centos-release
CentOS Linux release 7.3.1611 (Core)
並且是Minimal Install。
準備rpm包 ：
掛載CentOS-7-x86_64-Everything-1611.iso，把裏面所有文件都拷貝到本地目錄/yum/yum-iso
[[email protected] ~]# mkdir /mnt/yum-iso
[[email protected] ~]# mount /dev/cdrom /mnt/yum-iso/
mount: /dev/sr0 is write-protected, mounting read-only
[[email protected] ~]# mkdir /yum/
[[email protected] ~]# cp -a /mnt/yum-iso/ /yum/
[[email protected] ~]# ll /yum/
total 4
dr-xr-xr-x. 8 root root 4096 Dec 10 2015 yum-iso
[[email protected] ~]# ll /yum/yum-iso/
total 640
-r–r–r–. 1 root root 14 Dec 10 2015 CentOS_BuildTag
dr-xr-xr-x. 3 root root 33 Dec 10 2015 EFI
-r–r–r–. 1 root root 215 Dec 10 2015 EULA
-r–r–r–. 1 root root 18009 Dec 10 2015 GPL
dr-xr-xr-x. 3 root root 69 Dec 10 2015 images
dr-xr-xr-x. 2 root root 4096 Dec 10 2015 isolinux
dr-xr-xr-x. 2 root root 41 Dec 10 2015 LiveOS
dr-xr-xr-x. 2 root root 483328 Dec 10 2015 Packages
dr-xr-xr-x. 2 root root 4096 Dec 10 2015 repodata
-r–r–r–. 1 root root 1690 Dec 10 2015 RPM-GPG-KEY-CentOS-7
-r–r–r–. 1 root root 1690 Dec 10 2015 RPM-GPG-KEY-CentOS-Testing-7
-r–r–r–. 1 root root 2883 Dec 10 2015 TRANS.TBL
備份、移除其他repo
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# ll
-rw-r–r–. 1 root root 1664 Dec 9 2015 CentOS-Base.repo
-rw-r–r–. 1 root root 1309 Dec 9 2015 CentOS-CR.repo
-rw-r–r–. 1 root root 649 Dec 9 2015 CentOS-Debuginfo.repo
-rw-r–r–. 1 root root 290 Dec 9 2015 CentOS-fasttrack.repo
-rw-r–r–. 1 root root 630 Dec 9 2015 CentOS-Media.repo
-rw-r–r–. 1 root root 1331 Dec 9 2015 CentOS-Sources.repo
-rw-r–r–. 1 root root 1952 Dec 9 2015 CentOS-Vault.repo
[[email protected] yum.repos.d]# tar zcvf 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
[[email protected] yum.repos.d]# rm -f CentOS-Base.repo CentOS-CR.repo CentOS-Debuginfo.repo CentOS-fasttrack.repo CentOS-Sources.repo CentOS-Vault.repo
配置本地repo
[[email protected] yum.repos.d]# vi CentOS-Media.repo
填入如下內容：
[c7-media]
name=CentOS-$releasever - Mediabaseurl=file:///yum/yum-iso/gpgcheck=0enabled=1gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
註釋：配置repo路徑、關閉gbp校驗、啟用這個repo
制作cache
[[email protected] yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media
Cleaning up everything
Cleaning up list of fastest mirrors
[[email protected] yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
c7-media | 3.6 kB 00:00:00
(1/4): c7-media/group_gz | 155 kB 00:00:00
(2/4): c7-media/primary_db | 5.3 MB 00:00:00
(3/4): c7-media/filelists_db | 6.2 MB 00:00:00
(4/4): c7-media/other_db | 2.3 MB 00:00:00
Determining fastest mirrors
Metadata Cache Created
這樣就可以使用yum安裝軟件了
[[email protected] yum.repos.d]# yum groupinstall “Development tools”
Loaded plugins: fastestmirror
There is no installed groups file.
Maybe run: yum groups mark convert (see man yum)

自定義YUM源
[[email protected] yum.repos.d]# yum -y install createrepo
準備rpm包
（需要自己確定依賴包）、目錄。這裏使用tree做演示。
[[email protected] ~]# mkdir -p /yum/yum-custom/packages
創建repo
[[email protected] ~]# createrepo -u -d /yum/yum-custom/

drwxr-xr-x. 2 root root 41 Dec 20 07:03 packages
drwxr-xr-x. 2 root root 4096 Dec 20 07:08 repodata
配置自定義repo
[[email protected] ~]# vi /etc/yum.repos.d/CentOS-Media.repo
填入如下內容：
[c7-media]
name=CentOS-$releasever - Media
baseurl=file:///yum/yum-custom/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
制作cache：
[[email protected] ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media

[[email protected] ~]# yum makecache

(3/3): c7-media/other_db | 1.3 kB 00:00:00

[[email protected] ~]# yum install tree

制作局域網YUM源
局域網YUM源可以配成：本地YUM源 + FTP服務器
這裏使用自定義源yum-custom（上文所提到的目錄） + VSFTP演示。
下載vsftpd：
[[email protected] ~]# yum -y install vsftpd
配置vsftpd：
編輯vsftp.conf
[[email protected] ~]# vi /etc/vsftpd/vsftpd.conf
並增加匿名用戶root目錄（默認已經啟用匿名訪問）
anon_root=/yum/
註意目錄權限如下
[[email protected] ~]# ll -a /yum/
total 8
drwxr-xr-x. 4 root root 37 Dec 20 07:37 .
dr-xr-xr-x. 18 root root 4096 Dec 20 06:32 ..
drwxr-xr-x. 4 root root 36 Dec 20 07:08 yum-custom
dr-xr-xr-x. 8 root root 4096 Dec 10 2015 yum-iso
關閉selinux
臨時
[[email protected] ~]# setenforce 0
或者，永久：
編輯config
[[email protected] ~]# vi /etc/selinux/config
設置
SELINUX=disabled
重啟
[[email protected] ~]# reboot
啟用vsftp：
[[email protected] ~]# systemctl start vsftpd
[[email protected] ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
局域網使用：
局域網另外一臺機器zhdy-02，
配置repo：
[[email protected] ~]# vim /etc/yum.repos.d/CentOS-Media.repo
內容如下：
[c7-media]
name=CentOS-$releasever - Media
baseurl=ftp://192.168.96.129/yum-custom
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
其中192.168.96.129為上面vsftp服務器地址
啟用這個局域網的repo：
[[email protected] ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media
Cleaning up everything
[[email protected] ~]# yum makecache
Loaded plugins: fastestmirror
c7-media | 3.0 kB 00:00
(1/3): c7-media/filelists_db | 880 B 00:00
(2/3): c7-media/other_db | 1.3 kB 00:00
(3/3): c7-media/primary_db | 1.8 kB 00:00
Determining fastest mirrors
Metadata Cache Created
測試~
