CentOS7.2 创建本地YUM源和局域网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/

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

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)

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/

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

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。

一.用Centos镜像搭建本地yum源安装完linux系统的默认yum源为centos的官方地址,在"国内的特殊环境"下使用很慢甚至无法访问,所以一般的做法都是把默认的yum源替换成aliyun的yum源或者163等国内的yum源.但是以上的方法都是需要网络的,当没有网络的时候就无法使用了,所以还有一个常用的方法就是用Centos的iso镜像搭建本地yum源,这样安装软件的速度就会飞快,缺点是可能有些需要的包文件本地里没有. ? ?# 1.安装Centos后默认的yum源如下 [[e
