Linux系统本地yum源环境配置记录

 

由于IDC的一些服务器没有外网，不能对外访问。所以打算部署一套内网的yum源环境，以供内网服务器使用。以下简单记录下操作过程：

1）下载centos6.9和centos7.3的镜像，并挂载
[root@dev ~]# wget http://mirrors.163.com/centos/6.9/isos/x86_64/CentOS-6.9-x86_64-bin-DVD1.iso
[root@dev ~]# wget http://mirrors.163.com/centos/7.3.1611/isos/x86_64/CentOS-7-x86_64-DVD-1611.iso
[root@dev ~]# mount -o loop -t iso9660 CentOS-6.9-x86_64-bin-DVD1.iso  /mnt
[root@dev ~]# mount -o loop -t iso9660 CentOS-7-x86_64-DVD-1611.iso  /opt/aa
 
[root@dev ~]# ls /mnt/
CentOS_BuildTag  images                    repodata                       RPM-GPG-KEY-CentOS-Testing-6
EFI              isolinux                  RPM-GPG-KEY-CentOS-6           TRANS.TBL
EULA             Packages                  RPM-GPG-KEY-CentOS-Debug-6
GPL              RELEASE-NOTES-en-US.html  RPM-GPG-KEY-CentOS-Security-6
 
[root@dev ~]# ls /opt/aa/
CentOS_BuildTag  EULA  images    LiveOS    repodata              RPM-GPG-KEY-CentOS-Testing-7
EFI              GPL   isolinux  Packages  RPM-GPG-KEY-CentOS-7  TRANS.TBL
 
2）部署nginx
[root@dev ~]# yum install -y pcre pcre-devel openssl openssl-devel gcc
[root@dev ~]# groupadd -r nginx
[root@dev ~]# useradd -r -g nginx -s /bin/false -M nginx
[root@dev ~]# cd /usr/loca/src
[root@dev src]# wget http://nginx.org/download/nginx-1.8.0.tar.gz
[root@dev src]# tar -zxvf nginx-1.8.0.tar.gz
[root@dev src]# cd nginx-1.8.0
[root@dev nginx-1.8.0]# ./configure --prefix=/usr/local/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_flv_module --with-http_stub_status_module --with-http_gzip_static_module --with-pcre
[root@dev src]# make && make install
 
[root@dev ~]# cat /data/nginx/conf/vhosts/yum.conf
server {
    listen 80;
    server_name localhost;
    index index.html index.php index.htm;
 
    access_log  /data/nginx/logs/access.log main;
    error_log  /data/nginx/logs/error.log;
 
    location /{
    root /data/centos;
    autoindex on;
    autoindex_exact_size  off;          
    autoindex_localtime on;
    }
 
  }
 
[root@dev ~]# mkdir -p /data/centos/6/os/x86_64/6/
[root@dev ~]# mkdir -p /data/centos/7/os/x86_64/7/
[root@dev ~]# cp -r /mnt/* /data/centos/6/os/x86_64/6/
[root@dev ~]# cp -r /opt/aa/* /data/centos/7/os/x86_64/7/
 
[root@dev ~]# /data/nginx/sbin/nginx -t
[root@dev ~]# /data/nginx/sbin/nginx -s reload

访问http://192.168.1.240

然后就可以在客户机上配置自己的本地yum源，如下（其中192.168.1.240是上面yum源部署机的ip）
   
[root@dev ~]# cat centos6_yum.repo
[base]
name=kevin repo
baseurl=http://192.168.1.240/6/os/x86_64/6/
gpgcheck=0
enabled=1
[updates]
name=kevin update
baseurl=http://192.168.1.240/6/os/x86_64/6/
gpgcheck=0
enabled=1
   
[root@dev ~]# cat centos7_yum.repo
[base]
name=kevin repo
baseurl=http://192.168.1.240/7/os/x86_64/7/
gpgcheck=0
enabled=1
[updates]
name=kevin update
baseurl=http://192.168.1.240/7/os/x86_64/7/
gpgcheck=0                                      //不检查key
enabled=1
   
将上面的centos6或centos7的yum源文件放到客户机的/etc/yum.repos.d/目录下，然后执行下面两条命令即可：
# mv CentOS-Base.repo CentOS-Base.repo.bak
# yum clean all
# yum makecache

后续发现yum源里的包不全，有一些rpm的包不存在。发现是刚开始下载centos镜像的时候，只下载了CentOS-6.9-x86_64-bin-DVD1.iso，应该将CentOS-6.9-x86_64-bin-DVD2.iso的镜像也下载下来。然后挂载到本地，将里面os/x86_64/Packages下的rpm包拷贝到/data/centos/6/os/x86_64/6的Packages下，最后yum makecache就行了。
