• jboss的JVMroute记录


    jboss5的nodename是在

    /usr/local/jboss-5.1.0.GA/server/dms/deploy/jbossweb.sar/server.xml   这里的  jvmroute 

    需要和Apache对应

    最近公司要用到Jboss5.1,临时研究了下,发现与Jboss4配置相当多的不同,现在把配置过程发上来,希望对有需要的朋友,有帮助。(备注:经过测试的)

    jboss5.1+jdk6.0+apache2.2.11+mod_jk集群配置
    
    配置:
    1:环境变量配置
            JAVA_HOME=jdk1.6.0_14
            JBOSS_HOME=jboss-5.1.0.GA
            PATH
    2:JBOSS配置
            1:修改端口:
    JBOSS_HOME/server/all/deploy/jbossweb.sar/server.xml
    <!-- …
    <Connector protocol="HTTP/1.1" port="8080" address="${0.0.0.0}"
    ->
    <Engine name="jboss.web" defaultHost="localhost" jvmRoute="node1">
    …
    </Engine>
    
    将8080修改为你想要的端口,将${jboss.bind.address}修改为0.0.0.0,允许从eth0,eth1,lo都能够访问jboss 80端口,也可以在启动参数中指定ip地址选项,指定绑定的ip地址:run.bat -b x.x.x.*
    另外一台jboss同样配置,注意node2。
    补充:jboss的监听地址一定要写网卡绑定的ip,要跟前端apache mod_jk配置中指定的ip一致,最好在同一个网段如172.16.9.*,同时一定修改启动监听地址为0.0.0.0,否则apache 的mod-jk无法转发request.
    默认启动后,访问apache所在的机器ip。。。如果访问1服务,停掉1服务后,则会自动切换到2服务。
    2.放开useJK
    JBOSS_HOMEserveralldeployersjbossweb.deployerMETA-INFwar-deployers-jboss-beans.xml把下面注释放开,修改
     <property name="useJK">true</property>    
     <property name="useSessionPassivation">true</property>
     <property name="passivationMaxIdleTime">-1</property>  
     <property name="passivationMinIdleTime">-1</property>
    
    
    3.Apache配置
    a. 将下载的apache mod_jk重命名为mod_jk.so,复制到APACHE_HOME/modules/中,修改 APACHE_HOME/conf/httpd.conf,在文件末添加: 
    # Include mod_jk's specific configuration file
    Include conf/mod-jk.conf
    
    LoadModule proxy_module modules/mod_proxy.so 
    LoadModule proxy_http_module modules/mod_proxy_http.so
    LoadModule proxy_ajp_module modules/mod_proxy_ajp.so
    LoadModule proxy_balancer_module modules/mod_proxy_balancer.so
    LoadModule status_module modules/mod_status.so
    
    <Proxy *> 
           Order deny,allow
           allow from all
    </Proxy>
    
    ProxyPass / balancer://proxy/   stickysession=JSESSIONID nofailover=On lbmethod=byrequests
    ProxyPassReverse / balancer://proxy/
    <Proxy balancer://proxy>
            BalancerMember ajp://192.168.1.14:8009/  loadfactor=50  route=note1
            BalancerMember ajp://192.168.1.13:8009/  loadfactor=50  route=note2
    </Proxy>
    ProxyPass为代理转发的Url,即将所有访问/的请求转发到群集balancer://proxy 
    loadfactor为各主机间的负载比例参数,可是设置不同指数 
    BalancerMember为群集的成员,即群集服务器A或B,负载均衡服务器会根据均衡规则来将请求转发给BalancerMember.
    
    b. 在APACHE_HOME/conf/目录创建新文件mod-jk.conf,内容如下: 
    #Load mod_jk module
    # Specify the filename of the mod_jk lib
    LoadModule jk_module modules/mod_jk.so
     
    # Where to find workers.properties
    JkWorkersFile conf/workers.properties
    
    # Where to put jk logs
    JkLogFile logs/mod_jk.log
     
    # Set the jk log level [debug/error/info]
    JkLogLevel info 
     
    # Select the log format
    JkLogStampFormat  "[%a %b %d %H:%M:%S %Y]"
     
    # JkOptions indicates to send SSK KEY SIZE
    JkOptions +ForwardKeySize +ForwardURICompat -ForwardDirectories
     
    # JkRequestLogFormat
    JkRequestLogFormat "%w %V %T"
                   
    # Mount your applications
    JkMount /*.* loadbalancer
     
    # You can use external file for mount points.
    # It will be checked for updates each 60 seconds.
    # The format of the file is: /url=worker
    # /examples/*=loadbalancer
    JkMountFile conf/uriworkermap.properties               
    
    # Add shared memory.
    # This directive is present with 1.2.10 and
    # later versions of mod_jk, and is needed for
    # for load balancing to work properly
    JkShmFile logs/jk.shm 
                  
    # Add jkstatus for managing runtime data
    <Location /jkstatus/>
        JkMount status
        Order deny,allow
        Deny from all
        Allow from 127.0.0.1
    </Location>    
    
    c. 在APACHE_HOME/conf/目录创建新文件uriworkermap.properties,内容如下:
    /jmx-console=loadbalancer
    /jmx-console/*=loadbalancer
    /web-console=loadbalancer
    /web-console/*=loadbalancer
    这将配置从mod_jk将转发请求到/jmx-console,转发 /web-console 到JBOSS.
    
    d. 在APACHE_HOME/conf/目录创建新文件workers.properties,内容如下:
    # Define list of workers that will be used
    # for mapping requests
    worker.list=loadbalancer,status
    # worker.list=loadbalancer,node1,node2
    
    # Define Node1
    # modify the host as your host IP or DNS name.
    worker.node1.port=8009
    worker.node1.host=192.168.1.14
    worker.node1.type=ajp13
    worker.node1.lbfactor=1
    worker.node1.cachesize=100
    
    # Define Node2
    # modify the host as your host IP or DNS name.
    worker.node2.port=8009
    worker.node2.host= 192.168.1.13
    worker.node2.type=ajp13
    worker.node2.lbfactor=1
    worker.node2.cachesize=100
    
    # Load-balancing behaviour
    worker.loadbalancer.type=lb
    worker.loadbalancer.balance_workers=node1,node2
    worker.loadbalancer.sticky_session=1
    #worker.list=loadbalancer
    
    # Status worker for managing load balancer
    worker.status.type=status
    
    上面的文件中配置了两个节点,name分别为node1,node2,指定两个节点的IP,并在worker.loadbalancer.balance_workers中指定所有的node列表,
    worker.loadbalancer.sticky_session设置是否启用“粘着的”Session,sticky session是指来自同一IP的请求将被发送到同一个Jboss节点,
    sticky session设为0的话同一session的不同请求会被负载均衡分发到不同的jboss节点上。
    
    e. 修改应用程序的web.xml文件,添加<distributable />元素.
    保持session同步用
    
    至此,jboss集群环境已经基本配置完成,启动先启动apache,然后启动jboss,可测试,启动jboss时需指定run.bat -c all ,default配置是不支持集群的。
