搭建本地yum源和局域网yum源

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

[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/

Spawning worker 0 with 1 pkgs

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

error was [Errno 2] Local file does not exist: /etc/yum.repos.d/-d/packages/tree-1.6.0-10.el7.x86_64.rpm

[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/

在第二台VM上修改repo文件

baseurl=ftp://192.168.10.81

gpgcheck=0
