搭建本地yum源和區域網yum源
搭建本地yum源和區域網yum源
由於很多客戶環境是專網，不允許連網,無法使用網上的各種yum源，來回拷貝rpm包安裝麻煩，還得解決依賴問題。所以想著搭建個本地/區域網YUM源，方便安裝軟體。
1 搭建本地YUM源
環境：第一臺VM IP：192.168.10.81
第二臺VM IP：192.168.10.82
1.1 準備rpm包
虛擬機器掛載映象包CentOS-7-x86_64-Everything-1511.iso 開機啟動
掛載映象：
[[email protected] ~]# mount /dev/sr0 /mnt/
mount: /dev/sr0 is write-protected, mounting read-only
[[email protected] ~]# mkdir -p /yum/yum-iso #新建本地路徑/yum/yum-iso
把掛載的映象裡面所有檔案都拷貝到本地目錄/yum/yum-iso
[[email protected] ~]# cp -r /mnt/* /yum/yum-iso/
1.2 備份並移除其他repo
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] 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
[[email protected] yum.repos.d]# rm -rf *.repo
1.3 配置本地repo
[[email protected] 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路徑、關閉gbp校驗、啟用這個repo
1.4 製作cache
[[email protected] yum.repos.d]# yum clean all
Loaded plugins: fastestmirror
Cleaning repos: c7-media
Cleaning up everything
Cleaning up list of fastest mirrors
[[email protected] 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
[[email protected] yum.repos.d]#
這樣就可以使用yum安裝軟體了
[[email protected] ~]# yum install -y tree
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile

[[email protected] ~]#
安裝createrepo
[[email protected] ~]# yum install createrepo -y
準備RPM包
自己確定rpm包，目錄，這裡使用tree做演示
[[email protected] ~]# mkdir -p /yum/yum-custom/packages
[[email protected] ~]# cp /yum/yum-iso/Packages/tree-1.6.0-10.el7.x86_64.rpm /yum/yum-custom/packages/
[[email protected] ~]# createrepo -u -d /yum/yum-custom/

配置自定義repo
[[email protected] ~]# vi /etc/yum.repos.d/CentOS-Media.repo
[c7-media]
name=CentOS-$releasever-Media
baseurl=file:///yum/yum-custom/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
2 配置區域網yum源
將repo檔案改為
[[email protected] ~]# cat /etc/yum.repos.d/CentOS-Media.repo
[c7-media]
name=CentOS-$releasever-Media
baseurl=file:///yum/yum-iso/
gpgcheck=0
enabled=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
重新生成快取
[[email protected] ~]# yum clean all
[[email protected] ~]# yum makecache
安裝vsftp
[[email protected] ~]# yum install vsftpd -y
關閉selinux和防火牆
[[email protected] ~]# getenforce
Disabled
[[email protected] ~]# 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
[[email protected] ~]# systemctl stop firewalld
[[email protected] ~]# 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配置檔案
[[email protected] ~]# vi /etc/vsftpd/vsftpd.conf
在最末尾加上
anon_root=/yum/yum-custom/
啟動vsftp並設定開機啟動
[[email protected] ~]# systemctl start vsftpd
[[email protected] ~]# systemctl enable vsftpd
本地電腦訪問ftp://192.168.10.81
關鍵步驟:
生成repodata目錄，自動建立索引資訊
[[email protected] yum]# createrepo -pdo /yum/yum-custom/ /yum/yum-custom/
否則安裝tree的時候會出現報錯：
Error downloading packages:

[[email protected] yum.repos.d]# yum clean all
[[email protected] yum.repos.d]# yun makecache
在另一臺VM上設定repo檔案
[[email protected] ~]# cd /etc/yum.repos.d/
[[email protected] yum.repos.d]# rm -rf *
從第一臺VM上將repo檔案傳到第二臺VM上
[[email protected]ntos7-81 ~]# scp /etc/yum.repos.d/CentOS-Media.repo [email protected]:/etc/yum.repos.d/
