Nginx简单负载均衡

备注：系统采用Centos 6.4最小化安装

nginx部署

1.安装编译环境

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

2.安装pcre，zlib，openssl（pcre为了重写rewrite，zlib为了gzip，openssl为了https）

pcre

[root@nginx ~]# cd /home/WGY

[root@nginx WGY]# wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.30.tar.gz

[root@nginx WGY]# tar zxvf pcre-8.30.tar.gz

[root@nginx WGY]# cd pcre-8.30

[root@nginx WGY]# ./configure

[root@nginx WGY]# make && make install

zlib

[root@nginx WGY]#wget http://zlib.net/zlib-1.2.8.tar.gz

[root@nginx WGY]#tar zxvf zlib-1.2.8.tar.gz

[root@nginx WGY]#cd zlib-1.2.8

[root@nginx WGY]#./configure

[root@nginx WGY]#make && make install

openssl

[root@nginx WGY]#wget http://www.openssl.org/source/openssl-1.0.1e.tar.gz

[root@nginx WGY]#tar zxvf openssl-1.0.1e.tar.gz

nginx

[root@nginx WGY]#wget http://tengine.taobao.org/download/tengine-1.5.2.tar.gz

[root@nginx WGY]#tar zxvf tengine-1.5.2.tar.gz

[root@nginx WGY]#cd tengine-1.5.2

[root@nginx tengine-1.5.2]# ./configure --with-http_ssl_module \

--with-pcre=/home/WGY/pcre-8.30 \

--with-zlib=/home/WGY/zlib-1.2.8 \

--with-openssl=/home/WGY/openssl-1.0.1e \

--with-http_upstream_check_module

[root@nginx tengine-1.5.2]# make && make install

3.nginx配置负载均衡

[root@nginx ~]# cat /usr/local/nginx/conf/nginx.conf

pid logs/nginx.pid;    

events {    

   use epoll;

   client_header_buffer_size 1k;

   keepalive_timeout 65;    

   upstream mysvr {

      #ip_hash;    

       server 192.168.0.214;  

   }    

   server {    

       listen 80;    

         location / {    

           proxy_pass http://mysvr;

       }    

   }  

}
