篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了CentOS7.2 创建本地YUM源和局域网YUM源相关的知识，希望对你有一定的参考价值。
1背景
由于开发环境只有局域网，没法使用网上的各种YUM源，来回拷贝rpm包安装麻烦，还得解决依赖问题。
想着搭建个本地/局域网YUM源，方便自己跟同事安装软件。
2环境
[[email protected] ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
并且是Minimal Install。
3安装
3.1本地YUM源
3.1.1 ISO源
准备rpm包
挂载CentOS-7-x86_64-Everything-1511.iso，把里面所有文件都拷贝到本地目录/yum/yum-iso
[[email protected] ~]# mkdir /mnt/yum-iso [[email protected]-base ~]# mount /dev/cdrom /mnt/yum-iso/ mount: /dev/sr0 is write-protected, mounting read-only [[email protected]-base ~]# mkdir /yum/ [[email protected]-base ~]# cp -a /mnt/yum-iso/ /yum/ [[email protected]-base ~]# ll /yum/ total 4 dr-xr-xr-x. 8 root root 4096 Dec 10 2015 yum-iso [[email protected]-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 [[email protected]-base ~]#
备份、移除其他repo
[[email protected] ~]# cd /etc/yum.repos.d/ [[email protected]-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 [[email protected]-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 [[email protected]-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
[[email protected] yum.repos.d]# vi CentOS-Media.repo
填入如下内容
[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
注释：配置repo路径、关闭gbp校验、启用这个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]-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 [[email protected]-base yum.repos.d]#
这样就可以使用yum安装软件啦
[[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) 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
[[email protected] 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 自定义YUM源
[[email protected] yum.repos.d]# yum -y install createrepo
准备rpm包
（需要自己确定依赖包）、目录。这里使用tree做演示。
[[email protected] ~]# mkdir -p /yum/yum-custom/packages [[email protected]-base ~]# cp tree-1.6.0-10.el7.x86_64.rpm /yum/yum-custom/packages/
创建repo
[[email protected] ~]# 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 [[email protected]-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 [[email protected]-base ~]#
配置自定义repo
[[email protected] ~]# vi /etc/yum.repos.d/CentOS-Media.repo
填入如下内容
[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 Cleaning up everything Cleaning up list of fastest mirrors [[email protected]-base ~]# [[email protected]-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 [[email protected]-base ~]#
使用自定义repo
[[email protected] ~]# 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 局域网YUM源
局域网YUM源可以配成：本地YUM源 + FTP服务器
这里使用自定义源yum-custom（见上面） + VSFTP演示。
下载vsftpd
[[email protected] ~]# yum -y install vsftpd
配置vsftpd
编辑vsftp.conf
[[email protected] ~]# vi /etc/vsftpd/vsftpd.conf
并增加匿名用户root目录（默认已经启用匿名访问）
anon_root=/yum/
注意目录权限如下
[[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
关闭selinux
临时
[[email protected] ~]# setenforce 0
或者，永久：
编辑config
[[email protected] ~]# vi /etc/selinux/config
设置
SELINUX=disabled
重启
[[email protected] ~]# reboot
启用vsftp
[[email protected] ~]# systemctl start vsftpd [[email protected]-base ~]# systemctl enable vsftpd Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service. [[email protected]-base ~]#
局域网使用
局域网另外一台机器min-client，
配置repo
编辑repo
[[email protected] ~]# vim /etc/yum.repos.d/CentOS-Media.repo
内容如下
[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为上面vsftp服务器地址
启用这个局域网的repo
[[email protected] ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: c7-media Cleaning up everything [[email protected]-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 [[email protected]-client ~]#
使用
[[email protected] ~]# 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
目前差不多这些就够用了。以后有时间把163的YUM源爬下来，当本地源用。
