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
