CentOS7.2 创建本地与局域网yum源

1背景

由于客户环境只有局域网，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

[root@linuxidc.com ~]# 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

mkdir /mnt/yum-iso [root@linuxidc.com ~]# mount /dev/cdrom /mnt/yum-iso/ mount: /dev/sr0 is write-protected,mounting read-only [root@linuxidc.com ~]# mkdir /yum/ [root@linuxidc.com ~]# cp -a /mnt/yum-iso/ / [root@linuxidc.com ~]# ll / total 4 dr-xr-xr-x. 8 root root 4096 Dec 10 2015 iso [root@linuxidc.com ~]# ll /yum-iso/640 -r--r--r--. 1 root root 14 Dec 2015 CentOS_BuildTag dr-xr-xr-x. 3 root root 33 Dec EFI -r--r--r--. 1 root root 215 Dec EULA -r--r--r--. 1 root root 18009 Dec GPL dr-xr-xr-x. 69 Dec images dr-xr-xr-x. 2 root root isolinux dr-xr-xr-x. 2 root root 41 Dec LiveOS dr-xr-xr-x. 2 root root 483328 Dec Packages dr-xr-xr-x. repodata -r--r--r--. 1 root root 1690 Dec 2015 RPM-GPG-KEY-CentOS-7 -r--r--r--. 2015 RPM-GPG-KEY-CentOS-Testing-2883 Dec TRANS.TBL [root@linuxidc.com ~]#

备份、移除其他repo

[root@linuxidc.com ~]# cd /etc/yum.repos.d/
[root@linuxidc.com yum.repos.d]# ll
-rw-r--r--. 1 root root 1664 Dec  9  2015 CentOS-Base.repo
-rw-r--r--. 1309 Dec  CR.repo
-rw-r--r--. 649 Dec  Debuginfo.repo
-rw-r--r--. 290 Dec  fasttrack.repo
-rw-r--r--. 630 Dec  Media.repo
-rw-r--r--. 1331 Dec  Sources.repo
-rw-r--r--. 1952 Dec  Vault.repo
[root@linuxidc.com 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-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

[root@linuxidc.com 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=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

制作cache

clean all Loaded plugins: fastestmirror Cleaning repos: c7-media Cleaning up everything Cleaning up list of fastest mirrors [root@linuxidc.com makecache Loaded plugins: fastestmirror c7-media | 3.6 kB 00:00 (1/4): c7-media/group_gz | 155 kB 2/4): c7-media/primary_db | 5.3 MB 3/4): c7-media/filelists_db | 6.2 MB 4/4): c7-media/other_db | 2.3 MB Determining fastest mirrors Metadata Cache Created [root@linuxidc.com yum.repos.d]#

这样就可以使用yum安装软件啦

yum groupinstall "Development tools" Loaded plugins: fastestmirror There is no installed groups file. Maybe run: yum groups mark convert (see man ) Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package autoconf.noarch 0:2.69-11.el7 will be installed --> Processing Dependency: perl >= 5.006 for package: autoconf-.el7.noarch --> Processing Dependency: m4 >= 1.4.14 .el7.noarch --> Processing Dependency: perl(warnings) 11.el7.noarch

或者

install tree Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Resolving Dependencies --> Running transaction check ---> Package tree.x86_64 1.6.0-10.el7 will be installed --> Finished Dependency Resolution

3.1.2 自定义YUM源

yum -y install createrepo

（需要自己确定依赖包）、目录。这里使用tree做演示。

mkdir -p /yum-custom/packages [root@linuxidc.com ~]# cp tree-10.el7.x86_64.rpm /yum-custom/packages/

创建repo

[root@linuxidc.com ~]# createrepo -u -d  /
Spawning worker 0 with  pkgs
Spawning worker 1 with  pkgs
Workers Finished
Saving Primary Metadata
Saving  lists Metadata
Saving other Metadata

sqlite DBs complete
[root@linuxidc.com ~]# ll /
drwxr-xr-x. 20 07:03 packages
drwxr-xr-x. 08 repodata
[root@linuxidc.com ~]#

配置自定义repo

vi /etc/yum.repos.d/CentOS-Media.repo

yum/yum-custom/ gpgcheck=media Cleaning up everything Cleaning up list of fastest mirrors [root@linuxidc.com ~]# [root@linuxidc.com ~]# 3.0 kB 3): c7-media/filelists_db | 880 B 3): c7-media/primary_db | 1.8 kB 3): c7-media/other_db | 1.3 kB Determining fastest mirrors Metadata Cache Created [root@linuxidc.com ~]#

[root@linuxidc.com ~]# systemctl start vsftpd [root@linuxidc.com ~]# systemctl enable vsftpd Created symlink from /etc/systemd/system/multi-user.target.wants/vsftpd.service to /usr/lib/systemd/system/vsftpd.service. [root@linuxidc.com ~]#

[root@min-client ~]# vim /etc/ 内容如下

ftp://192.168.118.133/yum-custom gpgcheck= 其中192.168.118.133为上面vsftp服务器地址

启用这个局域网的repo

[root@min-client ~]# media
Cleaning up everything
[root@min-client ~]# 
(
Determining fastest mirrors
Metadata Cache Created
[root@min-client ~]#

使用

.el7 will be installed --> Finished Dependency Resolution

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。
