nginx+tomcat+memcached
1.nginx安装
nginx1.5.0
E:\nginx-1.5.0\conf,添加proxy.conf,gzip.conf
修改配置文件nginx.conf
#Nginx所用用户和组
#user niumd niumd;
#工作的子进程数量（通常等于CPU数量或者2倍于CPU）
worker_processes 1;
#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存放文件
pid logs/nginx.pid;
events {
#使用网络IO模型linux建议epoll，FreeBSD建议采用kqueue
#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;
include proxy.conf;
upstream mytest {
#根据ip计算将请求分配各那个后端tomcat，许多人误认为可以解决session问题，其实并不能。
#同一机器在多网情况下，路由切换，ip可能不同
#ip_hash;
#weigth参数表示权值，权值越高被分配到的几率越大
server 192.168.1.106:8081;
server 192.168.1.106:8082;
}
server {
listen 8099;
server_name 192.168.1.106;
location / {
#定义服务器的默认网站根目录位置
root html;
#定义首页索引文件的名称
index index.html index.htmindex.jsp;
proxy_connect_timeout 3;
proxy_send_timeout 30;
proxy_read_timeout 30;
proxy_pass http://mytest;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}
proxy.conf
proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 300; proxy_send_timeout 300; proxy_read_timeout 300; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k;
gzip.conf
gzip on; gzip_min_length 1024; gzip_buffers 4 8k; gzip_comp_level 9; gzip_proxied any; gzip_types application/xml application/javascript application/x-javascript application/atom+xml application/rss+xml; gzip_types text/css text/html text/javascript text/js text/plain text/xml;
2.tomcat7
准备tomcat7.1和tomcat7.2
tomcat7.1 server.xml 修改端口
<Server port="8101" shutdown="SHUTDOWN">
<Connector port="8081" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443"/>
<Connector port="8201" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat1">
tomcat7.2 server.xml 修改端口
<Server port="8102" shutdown="SHUTDOWN">
<Connector port="8082" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8202" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost" jvmRoute="tomcat2">
3.memcached session共享
3.0.安装memcached 1.4.4-14 window64
3.1.context.xml 7.1和7.2添加内容 tomcat和memcached整合
<Manager className="de.javakaffee.web.msm.MemcachedBackupSessionManager" memcachedNodes="n1:192.168.1.106:11211" sticky="false" sessionBackupAsync="false" lockingMode="none" sessionBackupTimeout="100" requestUriIgnorePattern=".*\.(ico|png|gif|jpg|css|js)$" transcoderFactoryClass="de.javakaffee.web.msm.serializer.kryo.KryoTranscoderFactory" />
3.2.需要的jar包 加入到E:\Tomcat\tomcat7.2\lib和E:\Tomcat\tomcat7.1\lib
couchbase-client-1.0.3.jar memcached-2.6.jar memcached-session-manager-1.5.1.jar memcached-session-manager-tc7-1.5.1.jar msm-javolution-serializer-1.5.1.jar msm-kryo-serializer-1.5.1.jar msm-xstream-serializer-1.5.1.jar kryo-1.03.jar kryo-serializers-0.10.jar minlog-1.2.jar reflectasm-0.9.jar
4.index.jsp页面
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%@ page import="java.text.SimpleDateFormat"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">

<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">

</head>
<body>
服务器信息:
<%
String dtm = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new Date());
System.out.println("["+request.getLocalAddr()+":"+ request.getLocalPort()+"]" + dtm);
out.println("<br>["+request.getLocalAddr()+":" +request.getLocalPort()+"]" + dtm+"<br>");
%>
session分发:
<%
//session.setAttribute("name","dennisit");
//HttpSession session = request.getSession(true);
System.out.println("[session分发] session id:"+session.getId());
out.println("<br>[session分发] session id： " + session.getId()+"<br>");
%>
</body>
</html>
5.结果测试
