nginx redis tomcat 集群中用到的命令

1. 防火墙端口修改

 vi /etc/sysconfig/iptables
 增加：-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT
 重启生效：service iptables restart

2.tomcat 多实例启动修改端口

  
(1).修改http访问端口（默认为8080端口）: 

<Connector port=”8080” protocol=”HTTP/1.1″ 
connectionTimeout=”20000″ 
redirectPort=”8443″ URIEncoding=”gb2312″/> 

(2).修改Shutdown端口（默认为8005端口）: 

<Server port=”8005” shutdown=”SHUTDOWN”> 

(3).修改JVM启动端口（默认为8009端口）: 

<Connector port=”8009” protocol=”AJP/1.3″ redirectPort=”8443″ /> 

3. nginx启动和停止

 /usr/local/nginx-1.7.8/sbin/nginx
 /usr/local/nginx-1.7.8/sbin/nginx -s reload
 /usr/local/nginx-1.7.8/sbin/nginx -s stop

4.nginx集群主要配置

  

http {
    upstream tomcat  {
        server localhost:8080;
        server localhost:8081;
    }

    include       mime.types;
    default_type  application/octet-stream;


    #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  logs/access.log  main;


    sendfile        on;
    #tcp_nopush     on;


    #keepalive_timeout  0;
    keepalive_timeout  65;


    #gzip  on;


    server {
        listen       80;
        server_name  localhost:8888;


        #charset koi8-r;


        #access_log  logs/host.access.log  main;


        location / {
            proxy_pass http://tomcat;
        }

  ...

  }

5. redis 启动和停止

   

   redis-server /etc/redis/6379.conf

   redis-cli

   key "*"  和 get "xxx" 查看session数据

6. tomcat中用到的lib

   commons-pool2-2.0.jar   jedis-2.5.2.jar   redissession.jar

   下载地址

7. tomcat中context.xml配置session复制

  <Valve className="com.orangefunction.tomcat.redissessions.RedisSessionHandlerValve" />
   <Manager className="com.orangefunction.tomcat.redissessions.RedisSessionManager"
         host="localhost"
         port="6379"
         database="0"
         maxInactiveInterval="60" />
