CentOS7搭建YUM源

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 iswrite-protected, mounting read-only

配置本地repo

[[email protected]]#viCentOS-Media.repo

填入如下内容

[c7-media]

name=CentOS-$releasever - Media

baseurl=file:///yum/yum-iso/gpgcheck=0enabled=1gpgkey=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

这样就可以使用yum安装软件啦

[[email protected]]#yumgroupinstall"Development tools"Loaded plugins: fastestmirror

There is no installed groupsfile.

Maybe run: yumgroupsmark convert (seemanyum)

3.1.2 自定义YUM源

[[email protected]]#yum-yinstallcreaterepo

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]~]#cptree-1.6.0-10.el7.x86_64.rpm /yum/yum-custom/packages/

创建repo

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-yinstallvsftpd

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 8drwxr-xr-x.4root root37Dec2007:37 .

dr-xr-xr-x.18root root4096Dec2006:32 ..

drwxr-xr-x.4root root36Dec2007:08yum-custom

dr-xr-xr-x.8root root4096Dec102015yum-iso

 关闭selinux

临时

[[email protected] ~]# setenforce0

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-customgpgcheck=0enabled=1gpgkey=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

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。
