nginx安装和域名转换配置

最近公司搭建一个新的业务平台，由于公网的IP地址和硬负载设备的配置问题，需要使用其它的办法做域名转换，于是使用nginx做的域名转换。

安装nginx

1.安装gcc

yum -y install gcc automake autoconf libtool make

yum install gcc gcc-c++

2.安装pcre

cd /usr/local/src

wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.34.tar.gz

tar -zxvf pcre-8.34.tar.gz

cd pcre-8.34

./configure

make

make install

3.安装zlib库

http://zlib.net/zlib-1.2.8.tar.gz 下载最新的 zlib 源码包，使用下面命令下载编译和安装 zlib包：

 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

4.安装nginx

wget http://nginx.org/download/nginx-1.5.4.tar.gz

wget http://nginx.org/download/nginx-1.4.2.tar.gz

Nginx 一般有两个版本，分别是稳定版和开发版，您可以根据您的目的来选择这两个版本的其中一个，下面是把 Nginx 安装到 /usr/local/nginx 目录下的详细步骤：

cd /usr/local/src

wget http://nginx.org/download/nginx-1.4.2.tar.gz

tar -zxvf nginx-1.4.2.tar.gz

cd nginx-1.4.2

./configure --prefix=/usr/local/nginx --without-http_memcached_module  --with-http_stub_status_module --with-openssl=/usr/ --with-pcre=/usr/local/src/pcre-8.34

或是

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

./configure --sbin-path=/usr/local/nginx/nginx

--conf-path=/usr/local/nginx/nginx.conf

--pid-path=/usr/local/nginx/nginx.pid

--with-http_ssl_module

--with-pcre=/usr/local/src/pcre-8.34

--with-zlib=/usr/local/src/zlib-1.2.8

--with-openssl=/usr/local/src/openssl-1.0.1c

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

make

make install--with-pcre=/usr/src/pcre-8.34 指的是pcre-8.34 的源码路径。

--with-zlib=/usr/src/zlib-1.2.7 指的是zlib-1.2.7 的源码路径。

#/usr/local/nginx/sbin/nginx   #启动nginx

#netstat -ano|grep 80   查看端口

设置nginx开启启动

vi /etc/rc.d/init.d/nginx #编辑启动文件添加下面内容

6.配置文件做域名转发

# Vim /usr/local/nginx/conf/nginx.conf

在行 #gzip  on; 下加入域名转换配置

#web_server是一个服务，指向xx.xx.xx.xx.的8116端口

upstream web_server {

#ip_hash; 

server xx.xx.xx.xx:8116 max_fails=2 fail_timeout=30s;

#server x.x.x.x:8080  max_fails=2 fail_timeout=30s;

}

server {

listen 80;

server_name abc.xxcom;   #不同的域名配置

location / {

    root html;

    index index.html index.htm;

proxy_next_upstream

http_502 http_504 error timeout invalid_header;

proxy_pass http://web_server;  #这里要配置成upstream的"web_server"

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

break;

     }

}

#web_server1是一个服务，指向xx.xx.xx.xx的8124端口

upstream web_server1 {

#ip_hash; 

server xx.xx.xx.xx:8124 max_fails=2 fail_timeout=30s;

}

server {

listen 80;

server_name xx.xx.com;    #转换的域名

location / {

    root html;

    index index.html index.htm;

proxy_next_upstream

http_502 http_504 error timeout invalid_header;

proxy_pass http://web_server1;

proxy_set_header Host $host;

proxy_set_header X-Real-IP $remote_addr;

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

break;

     }

}

配置完成。
