Linux系統本地yum源環境配置記錄

由于IDC的一些伺服器沒有外網，不能對外通路。是以打算部署一套内網的yum源環境，以供内網伺服器使用。以下簡單記錄下操作過程：

1）下載下傳centos6.9和centos7.3的鏡像，并挂載
[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
      

通路http://192.168.1.240

然後就可以在客戶機上配置自己的本地yum源，如下（其中192.168.1.240是上面yum源部署機的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                                      //不檢查key
enabled=1
   
将上面的centos6或centos7的yum源檔案放到客戶機的/etc/yum.repos.d/目錄下，然後執行下面兩條指令即可：
# mv CentOS-Base.repo CentOS-Base.repo.bak
# yum clean all
# yum makecache      

後續發現yum源裡的包不全，有一些rpm的包不存在。發現是剛開始下載下傳centos鏡像的時候，隻下載下傳了CentOS-6.9-x86_64-bin-DVD1.iso，應該将CentOS-6.9-x86_64-bin-DVD2.iso的鏡像也下載下傳下來。然後挂載到本地，将裡面os/x86_64/Packages下的rpm包拷貝到/data/centos/6/os/x86_64/6的Packages下，最後yum makecache就行了。
