# cd /usr/local/src# wget http://nginx-sticky-module.googlecode.com/files/nginx-sticky-module-1.1.tar.gz# tar -zxvf nginx-sticky-module-1.1.tar.gz |
二：查看现有nginx的编译参数，加上sticky模块参数重新编译。

#/usr/local/nginx/sbin/nginx –Vnginx version: nginx/1.3.14

# service nginx stop# cd /usr/local/src/nginx-1.3.14#./configure --prefix=/usr/local/nginx --user=nobody --group=nobody --with-select_module --with-poll_module --with-file-aio --with-http_ssl_module --with-http_realip_module --with-http_gzip_static_module --with-http_secure_link_module --with-http_sub_module --with-http_stub_status_module --add-module=/root/nginx-http-concat/ --add-module=/usr/local/src/nginx-sticky-module-1.1# make && make install |
三：修改配置文件，添加sticky相关参数
在类似如下位置添加参数（红色字体）
