1,安装依赖的库和包，否则编译会报错
apt-get install gcc libpcre3 libpcre3-dev openssl libssl-dev make
2，下载附件中的nginx-1.8.1.tar.gz 及nginx-sticky-module-1.1.tar.gz
备注：
nginx-sticky-module-1.1模块在附件中，下载附件后，重命名
mv aa.txt nginx-sticky-module-1.1.tar.gz
mv nginx-1.8.1.txt nginx-1.8.1.tar.gz
tar xf nginx-1.8.1.tar.gz
mkdir /usr/local/nginx-sticky-module-1.1/
tar xf nginx-sticky-module-1.1.tar.gz -C /usr/local/nginx-sticky-module-1.1/
cd nginx-1.8.1/
3，编译安装nginx
./configure --prefix=/usr/local/nginx-1.8.1 --with-http_stub_status_module --with-http_ssl_module --with-http_realip_module --add-module=/usr/local/nginx-sticky-module-1.1/nginx-sticky-module-1.1
会报错，根据错误提示修改文件（参考http://tenderrain.blog.51cto.com/9202912/1880880）
vim /usr/local/nginx-sticky-module-1.1/nginx-sticky-module-1.1/ngx_http_sticky_misc.c +281
make
make install
4，配置nginx.conf
cd /usr/local/nginx-1.8.1/conf
cat nginx.conf 内容如下：
worker_processes 5;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main ‘$remote_addr - $remote_user [$time_local] "$request" ‘
‘$status $body_bytes_sent "$http_referer" ‘
‘"$http_user_agent" "$http_x_forwarded_for"‘;
sendfile on;
keepalive_timeout 65;
map $cookie_jsessionid $route_cookie {
~.+\.(?P<route>\w+)$ $route;
}
map $request_uri $route_uri {
~jsessionid=.+\.(?P<route>\w+)$ $route;
}
upstream jiracluster {
server 10.32.115.91:8090;
server 10.32.115.92:8090;
sticky;
}
server {
listen 80;
server_name 10.32.116.28;
location / {
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_pass http://jiracluster;
}
error_log /tmp/error.log;
access_log /tmp/access.log;
}
}
5，检测语法，启动nginx
/usr/local/nginx-1.8.1/sbin/nginx -t
/usr/local/nginx-1.8.1/sbin/nginx
/usr/local/nginx-1.8.1/sbin/nginx -t
/usr/local/nginx-1.8.1/sbin/nginx -s reload
其实session持久化就nginx本身而言是有三种方式的
cookie
route
