nginx添加sticky cookie 分流模块

需要下载nginx源码和sticky，在nginx配置文件中添加sticky模块，然后重新编译nginx。

#准备安装基础环境：
yum install gcc openssl-devel pcre-devel zlib-devel

#下载nginx1.6.3
wget http://nginx.org/download/nginx-1.6.3.tar.gz

#解压缩nginx
tar xvf nginx-1.6.3.tar.gz

#安装依赖的库
yum -y install libxml2 libxml2-dev
yum -y install libxslt-devel
yum -y install gd-devel
yum -y install perl-devel perl-ExtUtils-Embed
yum -y install GeoIP GeoIP-devel GeoIP-data
yum -y install gperftools-devel

#查看nginx的配置
nginx -V

#加入sticky模块
cd nginx-1.6.3

#编译
make

make install

#停止nginx
service nginx stop

#替换nginx
cp /usr/sbin/nginx /usr/sbin/nginx.bak.20161009
cp ./objs/nginx  /usr/sbin/nginx

#修改nginx配置：

upstream test_server {
        server 10.2.118.48:8002;
