Nginx安装和反向代理配置
Nginx安装需要一些准备工作。 安装gcc等
yum -y install make zlib zlib-devel gcc-c++ libtool openssl openssl-devel
还需要安装pcre，PCRE(Perl Compatible Regular Expressions)是一个Perl库，包括 Perl兼容的正则表达式库。
yum -y install pcre
下载Nginx源码包，这里选择是1.7.8版本。并且解压缩，并且编译
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=表示安装的路径
make && make install
编译成功后，进入Nginx目录查看下版本，验证是否安装完成。
[root@ACtest ~]# cd /usr/local/nginx/sbin/
[root@ACtest sbin]#/usr/local/nginx/sbin/nginx //启动Nginx
[root@ACtest sbin]# ./nginx -v //验证下Nginx版本
nginx version: nginx/1.7.8
[root@chumjtest sbin]# ps aux|grep nginx //查看下Nginx启动进程
root 4684 0.0 0.0 103256 840 pts/1 S+ 15:14 0:00 grep nginx

nobody 32672 0.0 0.0 26748 3396 ? S Dec23 0:16 nginx: worker process
安装完成后对Nginx进行配置
[root@ACtest ~]#cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak //将主配置文件进行备份
[root@ACtest ~]#vim /usr/local/nginx/conf/nginx.conf //这里将原来的配置文件清空，替换新的配置文件。

}
将重启下Nginx，将nginx进程Kill掉即可
配置反向代理
通过nginx访问不同的web服务器的端口
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; //本机的信息
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;
}
配置完后，重启下Nginx。之后测试下。
[root@ACtest sbin]# curl -I http://localhost:9080
HTTP/1.1 200 OK
Server: nginx/1.7.8
