Chào mọi người. Hiện tại mình đang có vấn đề về Replication session giữa 2 server Liferay trên Tomcat 7.
Mô hình của mình như sau:
Mình có 1 server Apache và 2 server chạy Tomcat 7.
Hiện tại mình đã cấu hình load balancer giữa 2 server Tomcat 7.
Bây giờ mình muốn thực hiện Replication session. Mình đã tìm hiểu và làm theo hướng dẫn của 2 trang sau đây:
[url]http://www.liferay.com/community/wiki/-/wiki/Main/High+Availability+Guide#section-High+Availability+Guide-Tomcat+Clustering
[/url]
http://tomcat.apache.org/tomcat-7.0-doc/cluster-howto.html
Tuy nhiên mình gặp lỗi sau
Code:

INFO: Register manager localhost# to cluster element Engine with name Catalina
Jul 5, 2012 11:42:07 AM org.apache.catalina.ha.session.DeltaManager startInternal
INFO: Starting clustering manager at localhost#

This operation will timeout if no session state has been received within 60 seconds.

SEVERE: Manager [localhost#]: No session state send at 7/5/12 11:42 AM received, timing out after 60,050 ms.

WARNING: Manager [localhost#]: Drop message SESSION-GET-ALL inside GET_ALL_SESSIONS sync phase start date 7/5/12 11:42 AM message date 1/1/70 12:00 AM

Mình làm các bước sau:
Cấu hình file server.xml
Thêm <distributable/> trong web.xml
Config <Context distributable="true"> trong context.xml

File server.xml mình thêm đoạn như sau:
Code:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"
                 channelSendOptions="8">

          <Manager className="org.apache.catalina.ha.session.DeltaManager"
                   expireSessionsOnShutdown="false"
                   notifyListenersOnReplication="true"/>

          <Channel className="org.apache.catalina.tribes.group.GroupChannel">
            <Membership className="org.apache.catalina.tribes.membership.McastService"
                        address="228.0.0.4"
                        port="45564"
                        frequency="500"
                        dropTime="3000"/>
            <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver"
                      address="auto"
                      port="4000"
                      autoBind="100"
                      selectorTimeout="5000"
                      maxThreads="6"/>

            <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter">
              <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/>
            </Sender>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/>
            <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/>
          </Channel>

          <Valve className="org.apache.catalina.ha.tcp.ReplicationValve"
                 filter=""/>
          <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/>

          <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer"
                    tempDir="/tmp/war-temp/"
                    deployDir="/tmp/war-deploy/"
                    watchDir="/tmp/war-listen/"
                    watchEnabled="false"/>

          <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/>
          <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/>
        </Cluster>

Mình cấu hình giống nhau trên 2 server.
Mong nhận được sự góp ý của mọi người. Cảm ơn.

Nhìn không thấy có gì sai. Chỉ có 1 điểm từ tài liệu của tomcat:

Make sure your web.xml has the <distributable/> element

What bringing us together is stronger than what pulling us apart.

Em bổ thêm <distributable/> vào trong web.xml như sau:
-$TOMCAT_HOME/conf/web.xml
Code:

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
  xmlnssi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
                      http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
  version="3.0">
.....
  	<distributable/>
...
</web-app>

-%TOMCAT_HOME/webapp/ROOT/WEB-INF/web.xml
Code:

<?xml version="1.0"?>

<web-app id="Liferay_Portal" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee" xmlnssi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
	<distributable/>
	<context-param>

Em xin bổ sung thêm log khi startup Liferay:

Em nghĩ ở đây nó không truyền session qua mạng được.
Có cái lạ là khi cả 2 cùng startup lên thì em đăng nhập vào liferay không được, phải tắt 1 trong 2 con mới đăng nhập được.

To run session replication in your Tomcat 7.0 container, the following steps should be completed:

All your session attributes must implement java.io.Serializable
Uncomment the Cluster element in server.xml
If you have defined custom cluster valves, make sure you have the ReplicationValve defined as well under the Cluster element in server.xml
If your Tomcat instances are running on the same machine, make sure the tcpListenPort attribute is unique for each instance, in most cases Tomcat is smart enough to resolve this on it's own by autodetecting available ports in the range 4000-4100
Make sure your web.xml has the <distributable/> element
If you are using mod_jk, make sure that jvmRoute attribute is set at your Engine <Engine name="Catalina" jvmRoute="node01" > and that the jvmRoute attribute value matches your worker name in workers.properties
Make sure that all nodes have the same time and sync with NTP service!
Make sure that your loadbalancer is configured for sticky session mode.

Bồ cần thoả mãn hết tất cả những thứ ở trên và chú trọng những phần màu đỏ.

Cảm ơn anh, nhưng em chưa hiểu cái yêu cầu đầu tiên cho lắm.
Anh có thể giải thích giúp em "All your session attributes must implement java.io.Serializable" là gì và mình nên làm những gì không ạ ?
Cảm ơn anh 1 lần nữa.

Đây là phần thuộc về coding. Java application nào đó được deployed trên Tomcat phải có những class quản lý session được implement java.io.Serializable thì cluster trên tomcat mới hoạt động được. Hy vọng là liferay đã làm chuyện này rồi.

Bồ nên đọc thật kỹ:
http://www.liferay.com/community/wiki/-/wiki/Main/High+Availability+Guide#section-High+Availability+Guide-Tomcat+Clustering

có rất nhiều chi tiết cần kiểm tra cẩn thận. Nên soát lại từng dòng 1 coi thử có sót cái gì không.

Cảm ơn anh rất nhiều. Em sẽ tìm hiểu kỹ lại.

Anh comale cho em hỏi thêm tí.
Em đã config thành công replication session rồi, nguyên nhân là do ip broadcast là 127.0.0.1
Trong hướng dẫn của Tomcat có đoạn như sau
make sure you don't broadcast 127.0.0.1, this is a common error
Em sửa như sau:
Em đã change trong /etc/hosts thành
192.168.2.60 localhost
192.168.2.60 ubuntu
thay thế cho
127.0.0.1 localhost
127.0.1.1 ubuntu

Chạy riêng Replication session của liferay thôi thì ok, nhưng trong liferay em có cấu hình Terracotta nữa nên khi chính lại ip broadcast từ 127 sang 192 thì bị lỗi.
Em ifconfig thì thấy địa chỉ inet addr vẫn là 127.0.0.1. Em nghĩ nguyên nhân là ở đây
Code:

lo        Link encap:Local Loopback  
         inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:16436  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)

Bây giờ làm thế nào để em thay đổi inet addr của Local Loopback ?
hoặc có một giải pháp nào khác ?

Không nên thay đổi localhost thành IP không phải là 127.0.0.1 vì nó sẽ làm hỏng nhiều dịch vụ trên máy chủ.

Vấn đề em cần làm là chỉnh mỗi dịch vụ (tomcat, terracota...v..v...) để chúng listen trên các IP cụ thể thay vì dùng "localhost".
