Nginx安裝和反向代理配置
Nginx安裝需要一些準備工作。 安裝gcc等
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
還需要安裝pcre，PCRE(Perl Compatible Regular Expressions)是一個Perl庫，包括 Perl兼容的正則表達式庫。
yum -y install pcre
下載Nginx源碼包，這裏選擇是1.7.8版本。並且解壓縮，並且編譯
wget http://nginx.org/download/nginx-1.7.8.tar.gz tar zxcf nginx-1.7.8.tar.gz ./configure --prefix=/usr/local/nginx --with-pcre //--prefix=表示安裝的路徑 make && make install
編譯成功後，進入Nginx目錄查看下版本，驗證是否安裝完成。
[root@ACtest ~]# cd /usr/local/nginx/sbin/ [root@ACtest sbin]#/usr/local/nginx/sbin/nginx //啓動Nginx [root@ACtest sbin]# ./nginx -v //驗證下Nginx版本 nginx version: nginx/1.7.8 [root@chumjtest sbin]# ps aux|grep nginx //查看下Nginx啓動進程 root 4684 0.0 0.0 103256 840 pts/1 S+ 15:14 0:00 grep nginx root 32670 0.0 0.0 24304 700 ? Ss Dec23 0:00 nginx: master process /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf nobody 32671 0.0 0.0 26804 3824 ? S Dec23 0:00 nginx: worker process nobody 32672 0.0 0.0 26748 3396 ? S Dec23 0:16 nginx: worker process
安裝完成後對Nginx進行配置
[root@ACtest ~]#cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak //將主配置文件進行備份
[root@ACtest ~]#vim /usr/local/nginx/conf/nginx.conf //這裏將原來的配置文件清空，替換新的配置文件。

}將重啓下Nginx，將nginx進程Kill掉即可
配置反向代理
通過nginx訪問不同的web服務器的端口
如：localhost:9080 = 10.1.1.78:9080
在配置文件加入
server {
listen 9080; //代理的端口
server_name localhost; //本機的信息
location / {
proxy_pass http://10.1.1.78:9080/; //表示代理的地址
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
# access_log /home/logs/bb_access.log combined;
}配置完後，重啓下Nginx。之後測試下。
[root@ACtest sbin]# curl -I http://localhost:9080 HTTP/1.1 200 OK Server: nginx/1.7.8 Date: Mon, 26 Dec 2016 07:52:37 GMT Content-Type: text/html Content-Length: 1812 Connection: keep-alive Last-Modified: Tue, 14 Jun 2016 01:53:30 GMT ETag: "714-53533459b292a" Accept-Ranges: bytes
測試成功，表示網站可以正常訪問。
