本地yum源搭建步骤

1.1安装编译所必须的软件

yum -y install gcc automake autoconf libtool make gcc-c++

1.2安装PCRE库

cd /usr/local/src
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.37.tar.gz
tar -zxvf pcre-8.37.tar.gz
cd pcre-8.34
./configure
make
make install

1.3安装zlib库

cd /usr/local/src
wget http://zlib.NET/zlib-1.2.8.tar.gz
tar -zxvf zlib-1.2.8.tar.gz
cd zlib-1.2.8
./configure
make
make install

1.4安装Nginx

cd /usr/local/src
wget http://nginx.org/download/nginx-1.12.2.tar.gz
cd nginx-1.12.2
yum -y install openssl openssl-devel
./configure --with-http_stub_status_module --with-http_ssl_module

2. 修改nginx配置文件

user  root;
worker_processes  2;
error_log  logs/error.log;

pid        logs/nginx.pid;

events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  Application/octet-stream;
    client_max_body_size 20m;

    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;

    keepalive_timeout  65;

    #gzip  on;

        server {
        listen 443 ssl;
        server_name  repo.example.com;
        ssl on;

        ssl_certificate   cert/789615.pem;
        ssl_certificate_key  cert/789615.key;
        ssl_session_timeout 5m;
        ssl_ciphers HIGH:!aNULL:!MD5;
        ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
        ssl_prefer_server_ciphers on;

        location / {
            root  /opt/repo;
            autoindex on;
            } 

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
            }

        }
    }

创建存放同步源的目录（以centos7为例）

mkdir -p /opt/repo/centos/7/os/x86_64/
mkdir -p /opt/repo/centos/7/extras/x86_64/
mkdir -p /opt/repo/centos/7/updates/x86_64/
mkdir -p /opt/repo/epel/7/x86_64/

4.同步源文件

使用rsync工具同步互联网上的源文件

rsync -av rsync://mirrors.ustc.edu.cn/centos/7/os/x86_64/ /opt/repo/centos/7/os/x86_64/
rsync -av rsync://mirrors.ustc.edu.cn/centos/7/extras/x86_64/ /opt/repo/centos/7/extras/x86_64/
rsync -av rsync://mirrors.ustc.edu.cn/centos/7/updates/x86_64/ /opt/repo/centos/7/updates/x86_64/
rsync -av --exclude=debug rsync://mirrors.ustc.edu.cn/epel/7/x86_64/ /opt/repo/epel/7/x86_64/

5.创建repo文件

[base]
name=CentOS-$releasever - Base
baseurl=https://repo.example.com/centos/$releasever/os/$basearch/
enable=1
gpgcheck=0

[updates]
name=CentOS-$releasever - Updates
baseurl=https://repo.example.com/centos/$releasever/updates/$basearch/
enable=1
gpgcheck=0

[extras]
name=CentOS-$releasever - Extras
baseurl=https://repo.example.com/centos/$releasever/extras/$basearch/
enable=1
gpgcheck=0

[epel]
name=epel-$releasever
baseurl=https://repo.example.com/epel/$releasever/$basearch/
enable=1
gpgcheck=0

至此，本地yum源服务器搭建完成，内网中的其他服务器可以通过这台本地yum源服务器来安装部署和更新软件了，在考虑安全的前提下，极大地提升了我们的工作效率。今天的分享，你学会了吗？
