搭建本地yum源和局域网yum源
由于很多客户环境是专网，不允许连网,无法使用网上的各种yum源，来回拷贝rpm包安装麻烦，还得解决依赖问题。所以想着搭建个本地/局域网YUM源，方便安装软件。
1 搭建本地YUM源
环境：第一台VM IP：192.168.10.81
第二台VM IP：192.168.10.82
1.1 准备rpm包
虚拟机挂载镜像包CentOS-7-x86_64-Everything-1511.iso 开机启动
挂载镜像：
[root@centos7-81 ~]# mount /dev/sr0 /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[root@centos7-81 ~]# mkdir -p /yum/yum-iso #新建本地路径/yum/yum-iso
把挂载的镜像里面所有文件都拷贝到本地目录/yum/yum-iso
[root@centos7-81 ~]# cp -r /mnt/* /yum/yum-iso/
1.2 备份并移除其他repo
[root@centos7-81 ~]# cd /etc/yum.repos.d/
[root@centos7-81 yum.repos.d]# tar czvf 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@centos7-81 yum.repos.d]# rm -rf *.repo
1.3 配置本地repo
[root@centos7-81 yum.repos.d]# vi CentOS-Media.repo
[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：配置repo路径、关闭gbp校验、启用这个repo
1.4 制作cache
[root@centos7-81 yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media
Cleaning up everything
Cleaning up list of fastest mirrors
[root@centos7-81 yum.repos.d]# yum makecache
Loaded plugins: fastestmirror
c7-media | 3.6 kB 00:00:00
(1/4): c7-media/group_gz | 3.5 kB 00:00:00
(2/4): c7-media/primary_db | 679 kB 00:00:00
(3/4): c7-media/other_db | 174 kB 00:00:00
(4/4): c7-media/filelists_db | 258 kB 00:00:00
Determining fastest mirrors
Metadata Cache Created
[root@centos7-81 yum.repos.d]#
这样就可以使用yum安装软件了
[root@centos7-81 ~]# yum install -y tree
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

Complete!
[root@centos7-81 ~]#
安装createrepo
[root@centos7-81 ~]# yum install createrepo -y
准备RPM包
自己确定rpm包，目录，这里使用tree做演示
[root@centos7-81 ~]# mkdir -p /yum/yum-custom/packages
[root@centos7-81 ~]# cp /yum/yum-iso/Packages/tree-1.6.0-10.el7.x86_64.rpm /yum/yum-custom/packages/
[root@centos7-81 ~]# createrepo -u -d /yum/yum-custom/

drwxr-xr-x 2 root root 42 Oct 20 23:46 packages

配置自定义repo
[root@centos7-81 ~]# vi /etc/yum.repos.d/CentOS-Media.repo
[c7-media]
name=CentOS-$releasever-Media
baseurl=file:///yum/yum-custom/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
2 配置局域网yum源
将repo文件改为
[root@centos7-81 ~]# cat /etc/yum.repos.d/CentOS-Media.repo
[c7-media]
name=CentOS-$releasever-Media
baseurl=file:///yum/yum-iso/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
重新生成缓存
[root@centos7-81 ~]# yum clean all
[root@centos7-81 ~]# yum makecache
安装vsftp
[root@centos7-81 ~]# yum install vsftpd -y
关闭selinux和防火墙
[root@centos7-81 ~]# getenforce
Disabled
[root@centos7-81 ~]# cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of three two values:
# targeted - Targeted processes are protected,
# minimum - Modification of targeted policy. Only selected processes are protected.
# mls - Multi Level Security protection.
SELINUXTYPE=targeted
[root@centos7-81 ~]# systemctl stop firewalld
[root@centos7-81 ~]# systemctl disable firewalld
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.
Removed symlink /etc/systemd/system/basic.target.wants/firewalld.service.
修改vsftp配置文件
[root@centos7-81 ~]# vi /etc/vsftpd/vsftpd.conf
在最末尾加上
anon_root=/yum/yum-custom/
启动vsftp并设置开机启动
[root@centos7-81 ~]# systemctl start vsftpd
[root@centos7-81 ~]# systemctl enable vsftpd
本地电脑访问ftp://192.168.10.81
关键步骤:
生成repodata目录，自动创建索引信息
[root@centos7-81 yum]# createrepo -pdo /yum/yum-custom/ /yum/yum-custom/
否则安装tree的时候会出现报错：
Error downloading packages:
tree-1.6.0-10.el7.x86_64: failed to retrieve packages/tree-1.6.0-10.el7.x86_64.rpm from c7-media

[root@centos7-82 yum.repos.d]# yum clean all
[root@centos7-82 yum.repos.d]# yun makecache
在另一台VM上设置repo文件
[root@centos7-82 ~]# cd /etc/yum.repos.d/
[root@centos7-82 yum.repos.d]# rm -rf *
从第一台VM上将repo文件传到第二台VM上
[root@centos7-81 ~]# scp /etc/yum.repos.d/CentOS-Media.repo root@192.168.10.82:/etc/yum.repos.d/

[c7-media]

#baseurl=file:///yum/yum-iso/
baseurl=ftp://192.168.10.81
gpgcheck=0
enabled=1
