1背景
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。
想着搭建個本地/局域網YUM源，方便自己跟同事安裝軟件。
2環境
[root@min-base ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
並且是Minimal Install。
3安裝
3.1本地YUM源
3.1.1 ISO源
准備rpm包
掛載CentOS-7-x86_64-Everything-1511.iso，把里面所有文件都拷貝到本地目錄/yum/yum-iso
[root@min-base ~]# mkdir /mnt/yum-iso [root@min-base ~]# mount /dev/cdrom /mnt/yum-iso/ mount: /dev/sr0 is write-protected, mounting read-only [root@min-base ~]# mkdir /yum/ [root@min-base ~]# cp -a /mnt/yum-iso/ /yum/ [root@min-base ~]# ll /yum/ total 4 dr-xr-xr-x. 8 root root 4096 Dec 10 2015 yum-iso [root@min-base ~]# 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 [root@min-base ~]#
備份、移除其他repo
[root@min-base ~]# cd /etc/yum.repos.d/ [root@min-base 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 [root@min-base 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 [root@min-base 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
[root@min-base yum.repos.d]# vi CentOS-Media.repo
填入如下內容
[c7-media] name=CentOS-$releasever - Media baseurl=file:///yum/yum-iso/ gpgcheck=0 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
注釋：配置repo路徑、關閉gbp校驗、啟用這個repo
制作cache
[root@min-base yum.repos.d]# yum clean all Loaded plugins: fastestmirror Cleaning repos: c7-media Cleaning up everything Cleaning up list of fastest mirrors [root@min-base 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 [root@min-base yum.repos.d]#
這樣就可以使用yum安裝軟件啦
[root@min-base 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) Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package autoconf.noarch 0:2.69-11.el7 will be installed --> Processing Dependency: perl >= 5.006 for package: autoconf-2.69-11.el7.noarch --> Processing Dependency: m4 >= 1.4.14 for package: autoconf-2.69-11.el7.noarch --> Processing Dependency: perl(warnings) for package: autoconf-2.69-11.el7.noarch
或者
[root@min-base yum.repos.d]# yum install tree Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package tree.x86_64 0:1.6.0-10.el7 will be installed --> Finished Dependency Resolution
3.1.2 自定義YUM源
[root@min-base yum.repos.d]# yum -y install createrepo
准備rpm包
（需要自己確定依賴包）、目錄。這里使用tree做演示。
[root@min-base ~]# mkdir -p /yum/yum-custom/packages [root@min-base ~]# cp tree-1.6.0-10.el7.x86_64.rpm /yum/yum-custom/packages/
創建repo
[root@min-base ~]# createrepo -u -d /yum/yum-custom/ Spawning worker 0 with 1 pkgs Spawning worker 1 with 0 pkgs Workers Finished Saving Primary metadata Saving file lists metadata Saving other metadata Generating sqlite DBs Sqlite DBs complete [root@min-base ~]# ll /yum/yum-custom/ total 4 drwxr-xr-x. 2 root root 41 Dec 20 07:03 packages drwxr-xr-x. 2 root root 4096 Dec 20 07:08 repodata [root@min-base ~]#
配置自定義repo
[root@min-base ~]# 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
[root@min-base ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: c7-media Cleaning up everything Cleaning up list of fastest mirrors [root@min-base ~]# [root@min-base ~]# yum makecache Loaded plugins: fastestmirror c7-media | 3.0 kB 00:00:00 (1/3): c7-media/filelists_db | 880 B 00:00:00 (2/3): c7-media/primary_db | 1.8 kB 00:00:00 (3/3): c7-media/other_db | 1.3 kB 00:00:00 Determining fastest mirrors Metadata Cache Created [root@min-base ~]#
使用自定義repo
[root@min-base ~]# yum install tree Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package tree.x86_64 0:1.6.0-10.el7 will be installed --> Finished Dependency Resolution
3.2 局域網YUM源
局域網YUM源可以配成：本地YUM源 + FTP服務器
這里使用自定義源yum-custom（見上面） + VSFTP演示。
下載vsftpd
[root@min-base ~]# yum -y install vsftpd
配置vsftpd
編輯vsftp.conf
[root@min-base ~]# 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/
注意目錄權限如下
[root@min-base ~]# 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
[root@min-base ~]# setenforce 0
或者，永久：
編輯config
[root@min-base ~]# vi /etc/selinux/config
設置
SELINUX=disabled
重啟
[root@min-base ~]# reboot
啟用vsftp
[root@min-base ~]# systemctl start vsftpd [root@min-base ~]# systemctl enable vsftpd Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service. [root@min-base ~]#
局域網使用
局域網另外一台機器min-client，
配置repo
編輯repo
[root@min-client ~]# vim /etc/yum.repos.d/CentOS-Media.repo
內容如下
[c7-media] name=CentOS-$releasever - Media baseurl=ftp://192.168.118.133/yum-custom gpgcheck=0 enabled=1 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
其中192.168.118.133為上面vsftp服務器地址
啟用這個局域網的repo
[root@min-client ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: c7-media Cleaning up everything [root@min-client ~]# 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 [root@min-client ~]#
使用
[root@min-base ~]# yum -y install tree Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package tree.x86_64 0:1.6.0-10.el7 will be installed --> Finished Dependency Resolution
目前差不多這些就夠用了。以后有時間把163的YUM源爬下來，當本地源用。
