最近又要准备新的项目架构，涉及到apache-tomcatcluster的相关问题，主要是以nginx+tomcat，博文为生成环境简化，重在架构思想。

准备安装环境，安装pcre，可以使用pcre源码或者rpm包安装

yum install -y pcre*

安装nginx

1. tarzxvfnginx-1.4.1.tar.gz

2. cdnginx-1.4.1/

3. ./configure--prefix=/usr/local/nginx--with-http_stub_status_module--with-http_ssl_module

4. make

5. makeinstall

nginx.conf配置

user  nobody nobody;worker_processes 2;error_log  /usr/local/nginx/logs/error.log  crit;pid        /usr/local/nginx/nginx.pid;worker_rlimit_nofile 65535;events{use epoll;worker_connections 65535;}http{include       mime.types;default_type  application/octet-stream;#charset  gb2312;server_names_hash_bucket_size 128;client_header_buffer_size 32k;large_client_header_buffers 4 32k;client_max_body_size 8m;sendfile on;tcp_nopush     on;keepalive_timeout 60;tcp_nodelay on;fastcgi_connect_timeout 300;fastcgi_send_timeout 300;fastcgi_read_timeout 300;fastcgi_buffer_size 64k;fastcgi_buffers 4 64k;fastcgi_busy_buffers_size 128k;fastcgi_temp_file_write_size 128k;gzip on;gzip_min_length  1k;gzip_buffers     4 16k;gzip_http_version 1.0;gzip_comp_level 2;gzip_types       text/plain application/x-javascript text/css application/xml;gzip_vary on;#limit_zone  crawler  $binary_remote_addr  10m;log_format  access  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" $http_x_forwarded_for';access_log  /usr/local/nginx/logs/access.log  access;server{listen   80;server_name  web1.example.com;index index.html index.htm index.php;root  /usr/local/nginx/html;#limit_conn   crawler  20;location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)${root         /usr/local/nginx/html;expires      30d;}location ~ (\.jsp)|(\.do)${proxy_pass http://192.168.1.2:8080;proxy_redirect off;proxy_set_header HOST $host;proxy_set_header X-Real-IP $remote_addr;proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;client_max_body_size 10m;client_body_buffer_size 128k;proxy_connect_timeout 90;proxy_send_timeout 90;proxy_read_timeout 90;proxy_buffer_size 4k;proxy_buffers 4 32k;proxy_busy_buffers_size 64k;proxy_temp_file_write_size 64k;}location ~ .*\.(js|css)?${expires      1h;}}}

2、安装、配置tomcat

先安装jdk

rpm -ivh jdk-7u21-linux-i586.rpm

JAVA_HOME=/usr/java/jdk1.7.0_21CLASSPATH=$JAVA_HOME/lib:$JAVA_HOME/jre/libPATH=$PATH:$JAVA_HOME/bin:$JAVA_HOME/jre/binexport PATH CLASSPATH JAVA_HOME

安装tomcat

tar zxvf apache-tomcat-7.0.40.tar.gzcp -R apache-tomcat-7.0.40 /usr/local/tomcat

启动tomcat

/usr/local/tomcat/bin/startup.sh

在<host></host>标签之间添加上：

然后，修改$tomcat/conf/web.xml文件。

    
     
      index.html
     
     
      index.htm
     
     
      index.jsp
     
    

在<welcome-file-list>与<welcome-file>index.html</welcome-file>之间添加上：

    
     html
    

在/usr/local/tomcat/webapps/html目录下新建一个index.jsp，一个index.do

然后在浏览器上访问静态页面index.html

在浏览器上访问动态页面index.jsp、index.do
