liyao20060101

nginx tomcat memcached 实现session共享。
网上的很多帖子都过时了，有些根本不能下载。
 
1.下载附件
2.将jar 包 复制到 tomcat/lib（tomcat1和tomcat2都需要）
3.配置tomcat/conf/context.xml 增加以下内容（tomcat1和tomcat2都要配置）

<Manager
className="de.javakaffee.web.msm.MemcachedBackupSessionManager"
memcachedNodes="n1:localhost:11211"
requestUriIgnorePattern=".*\.(png|gif|jpg|css|js)$"
sessionBackupAsync="false" sessionBackupTimeout="100"
transcoderFactoryClass="de.javakaffee.web.msm.serializer.javolution.JavolutionTranscoderFactory"
copyCollectionsForSerialization="false" />
 4.配置nginx

#user  nobody;
worker_processes  2;
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
#pid        logs/nginx.pid;

events {
worker_connections  1024;
}

http {
include       mime.types;
default_type  application/octet-stream;
client_max_body_size 100M;
large_client_header_buffers 4 128k;
#log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
#                  '$status $body_bytes_sent "$http_referer" '

keepalive_timeout  65;
gzip on;
gzip_min_length 1k;
gzip_buffers 16 64k;
gzip_http_version 1.1;
gzip_comp_level 6;
gzip_types text/xml text/javascript text/css text/plain application/json application/xml application/javascript;
gzip_vary on;
upstream backend_server {

}
server {

server_name  backend_server;
#charset koi8-r;
#access_log  logs/host.access.log  main;

}
#error_page  404              /404.html;
# redirect server error pages to the static page /50x.html
#
error_page   500 502 503 504  /50x.html;
location = /50x.html {
root   html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
#    proxy_pass   http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
#    root           html;
#    fastcgi_pass   127.0.0.1:9000;
#    fastcgi_index  index.php;
#    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
#    include        fastcgi_params;
#}
# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
#    deny  all;
#}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#

#}

# HTTPS server
#
#server {
#    listen       443 ssl;
#    server_name  localhost;
#    ssl_certificate      cert.pem;
#    ssl_certificate_key  cert.key;

#    ssl_session_timeout  5m;
#    ssl_ciphers  HIGH:!aNULL:!MD5;
#    ssl_prefer_server_ciphers  on;
#    location / {
#        root   html;
#        index  index.html index.htm;
#    }
#}
}         
 5.安装memcached

memcached.exe -d install
更多命令请执行  memcached.exe -help
 6.从Windows 服务 启动memcached
 7.启动tomcat1 和 tomcat2
 8.登录系统，查看结果
 
补充：
hibernate [size=1em]memcached配置：
 

<!-- Jpa Entity Manager 配置 -->

<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter" ref="hibernateJpaVendorAdapter"/>
