CentOS搭建局域网YUM源

• 先搭建本地YUM源

  确认系统版本
  [root@moke ~]# cat /etc/redhat-release 
  CentOS Linux release 7.2.1511 (Core) 
  [root@moke ~]#
  

  准备资源：
  http://mirror.nsc.liu.se/centos-store/7.2.1511/isos/x86_64/CentOS-7-x86_64-Everything-1511.iso
  

  配置本地Yum源
  FTP方式上传系统ISO资源至home目录
  加载 CentOS的ISO镜像并挂载：
  [root@moke media]# cd /mnt/
  [root@moke mnt]# ls
  CentOS-7-x86_64-Everything-1511.iso
  [root@moke mnt]# mkdir dvdiso
  [root@moke mnt]# ls
  CentOS-7-x86_64-Everything-1511.iso  dvdiso
  [root@moke mnt]# mount -o loop -t iso9660 CentOS-7-x86_64-Everything-1511.iso dvdiso/
  mount: /dev/loop0 写保护，将以只读方式挂载
  umount -v /mnt/dvdiso 这是卸载
  

  cd /etc/yum.repos.d/
  //禁用yum的网络更新方式，简单地将默认首选的CentOS-Base.repo改名为CentOS-Base.repo.bak即可
  mv CentOS-Base.repo CentOS-Base.repo.bak 
  [root@moke yum.repos.d]# ls
  CentOS-Base.repo
  
  [root@moke yum.repos.d]# cat CentOS-Base.repo 
  [base]
  name=CentOS-7 - Base
  #mirrorlist=http://mirrorlist.centos.org/?release=7&arch=$basearch&repo=os&infra=$infra
  baseurl=file:///mnt/dvdiso/
  gpgcheck=1
  enable=1
  gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
  [root@moke yum.repos.d]# 
  其中baseurl修改为ISO的挂载目录，enabled=1开启本地更新模式
  

  清除原有的yum信息并建立缓存文件
  [root@moke yum.repos.d]# yum clean all
  已加载插件：fastestmirror
  正在清理软件源： base c7-media centosplus extras updates
  Cleaning up everything
  
  [root@moke yum.repos.d]# yum makecache
  

  检查ISO软件列表
  [root@moke yum.repos.d]# yum list
  Loaded plugins: fastestmirror
  Determining fastest mirrors
  

• nginx安装

  上传文件至nginx-1.18.0.tar.gz 服务器
  

  安装依赖
  yum -y install zlib zlib-devel openssl openssl-devel pcre pcre-devel openssl openssl-devel gcc
  

  错误处理：
  Error: Package: glibc-devel-2.17-105.el7.x86_64 (base)
             Requires: glibc = 2.17-105.el7
             Installed: glibc-2.17-157.el7_3.2.x86_64 (@update)
                 glibc = 2.17-157.el7_3.2
             Available: glibc-2.17-105.el7.x86_64 (base)
                 glibc = 2.17-105.el7
  解决方法：
  yum downgrade glibc glibc-devel glibc-common glibc-headers
  

  编译安装
  使用普通权限用户安装，安全起见。
  [moke@moke ~]$ cd nginx-1.18.0
  配置
  ./configure --prefix=/home/moke/nginx
  编译安装
  make && make install
  检测nginx的配置是否正确
  /home/moke/nginx/sbin
  命令
  ./nginx -t
  nginx: the configuration file /home/moke/nginx/conf/nginx.conf syntax is ok
  nginx: configuration file /home/moke/nginx/conf/nginx.conf test is successful
  
  启动
  ./nginx
  

  配置nginx
  
  http {
      include       mime.types;
      default_type  application/octet-stream;
  
      #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
      #                  '$status $body_bytes_sent "$http_referer" '
      #                  '"$http_user_agent" "$http_x_forwarded_for"';
  
      #access_log  logs/access.log  main;
  
      sendfile        on;
      #tcp_nopush     on;
  
      #keepalive_timeout  0;
      keepalive_timeout  65;
  
      #gzip  on;
  
      server {
          listen       8080; #普通用户只能启动1024以上端口
          server_name  localhost;
  
          #charset koi8-r;
  
          #access_log  logs/host.access.log  main;
  
          location / {
              autoindex  on;
              root   /mnt/dvdiso; #此处为服务器镜像路径
              #index  index.html index.htm;
          }
  

  nginx重新加载配置
  ./nginx -s reload
  
  
  

  访问效果

  

  配置yum client
  vi /etc/yum.repos.d/nginx.repo
