tomcat:9300配置�?ji��n)abin�q�个java工程�Q�它里面的index.html内容为hello�Q�lee

那么上面的第二个地址打印hello�Q�abin
那么上面的第四个地址打印hello�Q�lee

本地hosts文�g配置为：(x��)

Nginx+tomcat配置集群

�?ji��n)解了(ji��n)二者之间的区别于应用场景，对Nginx产生��厚的兴��，阅读张宴�?lt;实战Nginx>�Q�这�?5�q�的��伙子年��L��为�M�?妒忌�Q�，搞明白了(ji��n)大致原理和配�|�，Ubuntu10.10�Q�window下对Nginx+tomcat负蝲均衡做了(ji��n)配置��试�Q�将全部��h��转发到tomcat�Q��ƈ未做�?r��n)态，动态分开�Q�图片防盗链�{�配�|��?br />Nginx 介绍

Nginx �Q�发韛_�� engine x�Q�是一�ƾ轻量��的Web 服务器／反向代理服务器及(qi��ng)�?sh��)子邮�g�Q�IMAP/POP3�Q�代理服务器�Q��ƈ在一个BSD-like 协议下发行�?nbsp; 其特�Ҏ(gu��)��占有内存��，�q�发能力强，事实上nginx的�ƈ发能力确实在同类型的�|�页伺服器中表现较好.目前中国大陆使用nginx�|�站用户有：(x��)新浪、网易�?腾讯,另外知名的微�|�志Plurk也��用nginx�?/p>

上面的全是Nginx介绍基本上是废话�Q�下面�{入正题，图文�l�合展示基本配置�Q�首先是window环境、其�ơ是Ubuntu环境�Q�Vbox虚拟�Q�。本文主要基于Nginx下配�|�两台tomcat�Q�结构如下图�Q?br />

Window xp环境�Q�Nginx+Tomcat6

1、下载地址

http://nginx.org/en/download.html �Q�这里我们推荐下载稳定版�Q�stable versions�Q�，本文采用nginx-0.8.20�?/p>

2、目录结�?/strong>

      Nginx-

               |_ conf   配置目录

               |_ contrib

               |_ docs 文档目录

               |_ logs 日志目录

               |_ temp 临时文�g目录

               |_ html �?r��n)态页面目�?/p>
               |_ nginx.exe �ȝ��?/p>

      window下安装Nginx极其��单，解压�~�到一个无�I�格的英文目录即可（个�h�?f��n)惯�Q�担�?j��)中文出问题�Q�，双击nginx启动�Q�这里我安装刎ͼ�(x��)D:\server目录�Q�下面涉�?qi��ng)到的tomcat也安装在此目录�?/p>


DOS环境启动

若果惛_��止nginx�Q�dos环境�q�行命��o(h��)�Q�nginx -s stop

3、nginx.conf配置

   Nginx配置文�g默认在conf目录�Q�主要配�|�文件�ؓ(f��)nginx.conf�Q�我们安装在D:\server\nginx-0.8.20、默认主配置文�g为D:\server\nginx-0.8.20\nginx.conf。下面是nginx作�ؓ(f��)前端反向代理服务器的配置�?/p>
#Nginx所用用户和�l�，window下不指定 #user niumd niumd; #工作的子�q�程数量�Q�通常�{�于CPU数量或�?倍于CPU�Q? worker_processes 2; #错误日志存放路径 #error_log logs/error.log; #error_log logs/error.log notice; error_log logs/error.log info; #指定pid存放文�g pid logs/nginx.pid; events { #使用�|�络IO模型linux��epoll�Q�FreeBSD��采用kqueue�Q�window下不指定�? #use epoll; #允许最大连接数 worker_connections 2048; } http { include mime.types; default_type application/octet-stream; #定义日志格式 #log_format main '$remote_addr - $remote_user [$time_local] $request ' # '"$status" $body_bytes_sent "$http_referer" ' # '"$http_user_agent" "$http_x_forwarded_for"'; #access_log off; access_log logs/access.log; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; client_header_buffer_size 1k; large_client_header_buffers 4 4k; sendfile on; tcp_nopush on; tcp_nodelay on; #keepalive_timeout 75 20; include gzip.conf; upstream localhost { #�Ҏ(gu��)��ip计算��请求分配各那个后端tomcat�Q�许多�h误认为可以解决session问题�Q�其实�ƈ不能�? #同一机器在多�|�情况下�Q��\由切换，ip可能不同 #ip_hash; server localhost:18081; server localhost:18080; } server { listen 80; server_name localhost; location / { proxy_connect_timeout 3; proxy_send_timeout 30; proxy_read_timeout 30; proxy_pass http://localhost; } } }

   代理讄��如下�Q?/p>
proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 300; proxy_send_timeout 300; proxy_read_timeout 300; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k;

   gzip压羃相关配置如下�Q?/p>
gzip on; gzip_min_length 1000; gzip_types text/plain text/css application/x-javascript;

4、Tomcat配置

   对于tomcat大家都很熟�?zh��n)��Q�只需要修改server.xml配置文�g卛_��Q�这里我们以apache-tomcat-6.0.14��Z��Q�分别在server目录�Q�解压羃�q�命名�ؓ(f��)�Q�apache-tomcat-6.0.14_1、apache-tomcat-6.0.14_2�?/p>

    �W�一处端口修改：(x��)

   �W�三处端口修改：(x��)

   Engine元素增加jvmRoute属性：(x��)

    两个tomcat的端口别重复�Q�保证能启动��h��Q�另一个tomcat配置希捷省略�Q�监听端口�ؓ(f��)18080�Q�附件中我们��上传所有的配置信息�?/p>

5、验证配�|�与��试负蝲均衡

    首先��试nginx配置是否正确�Q�测试命令：(x��)nginx -t (默认验证:conf\nginx.conf),也可以指定配�|�文件�\径�?/p>
此例nginx安装目录�Q�D:\server\nginx-0.8.20�Q�dos环境下图画面成功�C�Z��Q?br />

   其次验证tomcat�Q�启动两个tomcat�Q�不出现端口冲突即�ؓ(f��)成功�Q�tomcat依赖的java�{�搞“挨踢”的就废话不说�?ji��n)�?j��)�Q?/p>

    最后验证配�|�负载均衡设�|�，http://localhost/ �?a style="background-color: transparent; color: rgb(102,102,102)" href="http://localhost/index.jsp" mce_href="http://localhost/index.jsp">http://localhost/index.jsp 。我修改�?ji��n)index.jsp��面�Q�增加日志输��Z��息，便于观察。注意：(x��)左上角小猫头上的�Q�access tomcat2、access tomcat1。说明访问了(ji��n)不同的tomcat�?/p>


     ��x��window下nginx+tomcat负蝲均衡配置�l�束�Q�关于tomcat Session的问题通常是采用memcached�Q�或者采用nginx_upstream_jvm_route �Q�他是一�?Nginx 的扩展模块，用来实现��Z�� Cookie �?Session Sticky 的功能。如果tomcat�q�多不徏议session同步�Q�server间相互同步session很耗资源，高�ƈ发环境容易引起Session风暴。请�Ҏ(gu��)��自己应用情况合理采纳session解决�Ҏ(gu��)��?/p>
