解決問題：
Windows(192.168.25.11)和CentOS(192.168.106.231)在公司內網中，但是CentOS不能上網，Windows可以上網，需要在CentOS上安裝比較多的軟件，離線安裝太麻煩。因此，爲了能讓CentOS使用yum聯網安裝，做一下工作。
1、在windows上搭建Nginx正向代理服務器
1、在Nginx官網下載最新穩定版http://nginx.org/en/download.html
2、Windows系統上安裝Nginx( 解壓即可)。
cd c:\
unzip nginx-1.13.1.zip
cd nginx-1.13.1
start nginx3、配置Nginx正向代理( nginx.conf)。
worker_processes 1;
events {
worker_connections 1024;
}
http {
resolver 192.168.99.100; # 對本機可用的DNS
server {
listen 8000; # 監聽端口
location / {
proxy_pass http://$http_host$request_uri;
}
}
}4、重啓nginx即可
2、設置CentOS使用代理上網
1、暫時使用代理 (設置http代理爲Windows上的Nginx即可)
export http_proxy="http://192.168.25.11:8000"測試：
[root@dras-test yum.repos.d]# wget www.baidu.com
--2017-06-12 16:00:16-- http://www.baidu.com/
正在連接 192.168.25.11:8000... 已連接。
已發出 Proxy 請求，正在等待迴應... 200 OK
長度：2381 (2.3K) [text/html]
正在保存至: “index.html”
100%[===================================================================================================>] 2,381 --.-K/s in 0s
2017-06-12 16:00:16 (338 MB/s) - 已保存 “index.html” [2381/2381])
成功，可以用代理上網了！
2、永久使用代理
yum裏面可以單獨設置代理
就是yum源的參數加proxy=“http://ip：PORT”
即在/etc/yum.conf中加入下面幾句.
proxy=http://192.168.25.11:8000
proxy_username=username #可選
proxy_password=password #可選
另外:
/root/.bashrc中加入:
export http_proxy=”http://username:[email protected]:8000”
如果是通過ip或電腦的網卡地址認證,可忽略所有username 和 password .
注:停止使用代理的時候,要把改過的文件改成原樣.尤其是如果使用了export http_proxy=”http://192.168.25.11:8000”命令,
要在命令行輸入: unset http_proxy ,去除環境變量.
因爲export http_proxy=”http://192.168.25.11:8000”這條命令的實質是把export後面的設置寫進環境設置文件中.
3、設置CentOS的yum源（此步可選，爲了選擇國內速度快的yum源）
1，進入yum源配置目錄
cd /etc/yum.repos.d2，備份系統自帶的yum源
mv CentOS-Base.repo CentOS-Base.repo.bk下載163網易的yum源：
wget http://mirrors.163.com/.help/CentOS6-Base-163.repo3，更新玩yum源後，執行下邊命令更新yum配置，使操作立即生效
yum makecache4，除了網易之外，國內還有其他不錯的yum源，比如中科大和搜狐的，大家可以根據自己需求下載
中科大的yum源：
wget http://centos.ustc.edu.cn/CentOS-Base.reposohu的yum源
wget http://mirrors.sohu.com/help/CentOS-Base-sohu.repo理論上講，這些yum源redhat系統以及fedora也是可以用 的，但是沒有經過測試，需要的站長可以自己測試一下。
4、yum安裝軟件
# yum install php php-fpm php-cli php-pdo php-mysql php-gd php-bcmath php-xml php-mbstring php-mcrypt php-redisLoaded plugins: aliases, changelog, downloadonly, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify, versionlock
