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。想着在CentOS7.2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] ~]# 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/

备份、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
填入如下内容
[c7-media]
name=CentOS-KaTeX parse error: Expected 'EOF', got '#' at position 190: …om yum.repos.d]#̲ yum clean all …releasever - Media

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] ~]# systemctl enable vsftpd
Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service.
[[email protected] ~]#
局域网使用
局域网另外一台机器min-client，
配置repo
编辑repo
[root@min-client ~]# 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
[root@min-client ~]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media
Cleaning up everything
[root@min-client ~]# yum makecache

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。
