nginx整合tomcat

1、准备软件(存放在目录/home/sofeware下)

agentzh-headers-more-nginx-module-v0.15rc2-0-g2c629de.tar.gz  #支持隐藏头部信息  (不是必须，觉得需要就安装吧)

nginx-upstream-jvm-route-0.1.tar.gz   #nginx会话记录的必须模块   （用于tomcat集群,单tomcat就直接忽略相关操作）

pcre-8.10.tar.gz    #包括 perl 兼容的正规表达式库 (shell>rpm -qa|grep pcre 可以检查系统是否已存在)

nginx-1.0.4.tar.gz

apache-tomcat-7.0.11.tar.gz  (安装相对简单、资料也比较多，这里不演示了)

2、 编译安装

shell>cd /home/sofeware
shell>tar zxf pcre-8.10.tar.gz &&cd pcre-8.10
shell>./configure && make && make install
shell>cd ..
shell>tar zxf agentzh-headers-more-nginx-module-v0.15rc2-0-g2c629de.tar.gz
shell>tar zxf nginx-upstream-jvm-route-0.1.tar.gz
shell>tar zxf nginx-1.0.4.tar.gz
shell>cd nginx-1.0.4
shell>patch -p0 < /home/sofeware/nginx_upstream_jvm_route/jvm_route.patch
shell>./configure  --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
      --add-module=/home/sofeware/nginx_upstream_jvm_route/  
      --add-module=/home/sofeware/agentzh-headers-more-nginx-module-2c629de/
      && make && make install

3、配置 (默认80端口)

配置文件：/usr/local/nginx/conf/nginx.conf

//运行nginx所在的用户名和用户组
user nginx nginx;
worker_processes  1;
//全局错误日志及PID文件
error_log   /usr/local/nginx/logs/error.log;
pid         /usr/local/nginx/nginx.pid;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    //全局访问日志
    access_log  /usr/local/nginx/logs/access.log;    
    sendfile        on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        root   /var/www/test; //网站根目录
        #charset koi8-r; 
        access_log  /usr/local/nginx/logs/host.access.log;
        location / {
            //将index.jsp 加入到默认的访问首页地址
            index  index.html index.htm index.jsp; 
        }
        //所有jsp的页面均交由tomcat处理
        location ~ .*.jsp$ {
            index index.jsp;
            proxy_pass http://localhost:8080;
        }
        //设定访问静态文件直接读取不经过tomcat
        location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ {
            expires 30d;
        }
        location ~ .*\.(js|css)?$ {
            expires 1h;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

4、测试配置

shell>/usr/local/nginx/sbin/nginx -t
//出现如下信息表示配置成功，否则检查配置文件
the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok　　
the configuration file /usr/local/nginx/conf/nginx.conf was tested successfully  

5、启动、、重启、停止

shell>/usr/local/nginx/sbin/nginx  //启动
shell>/user/local/nginx/sbin/nginx -s reload //重启
shell>/usr/local/nginx/sbin/nginx -s stop //停止

6、添加新模块(非覆盖安装)

NginxHttpRealIpModule //有些网站使用这样的方式来搭建分布式缓存，若干台Squid放在前面提供缓存服务，内容从后面的 Nginx获取。不过如此一来，Nginx日志里看到的IP就是Squid的IP了，为了能让Nginx透明获取IP，可以使用 NginxHttpRealIpModule

ngx_cache_purge-1.3.tar.gz  //通过该模块使得Nginx可以像squid使用PURGE指令手动清除指定URL的缓存页面

shell>/usr/local/nginx/sbin/nginx -s stop //关闭nginx服务
shell>tar zxf ngx_cache_purge-1.3.tar.gz
shell>cd ..
shell>tar zxf nginx-1.0.4.tar.gz
shell>cd nginx-1.0.4
shell>patch -p0 < /home/sofeware/nginx_upstream_jvm_route/jvm_route.patch
shell>./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module 
      --with-http_realip_module //新增模块
      --add-module=/home/sofeware/nginx_upstream_jvm_route/ 
      --add-module=/home/sofeware/agentzh-headers-more-nginx-module-2c629de/
      --add-module=/home/sofeware/ngx_cache_purge-1.3/  //新增模块
shell>make  //编译即可，无需make install
shell>mv /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak //备份执行文件 
shell>cp -r objs/nginx /usr/local/nginx/sbin/
shell>/usr/local/nginx/sbin/nginx -t  //测试是否通过
shell>rm -rf /usr/local/nginx/nginx.pid  //删除PID，具体文件路径按自己的配置的实际情况
shell>/usr/local/nginx/sbin/nginx //重启
shell>/usr/local/nginx/sbin/nginx -V //查看编译参数
