5.1 Zookeeper cluster is not configured, see previous blog

5.2 Activemq Installation Package

  Description:zk03  is zookeeper  activemq03  is ACTIVEMQ  jdk  is the Java environment  redis no tube   All three machines are deployed  [[email protected] opt]# pwd/opt[[email protected] opt]# lltotal  12lrwxrwxrwx  1 root root    21 dec 31 18:20  activemq03 -> apache-activemq-5.9.0drwxr-xr-x 10  501 games 4096  Oct 15  2013 apache-activemq-5.9.0lrwxrwxrwx  1 root root     11 dec 25 01:27 jdk -> jdk1.7.0_80drwxr-xr-x  8    10   143 4096 apr 11  2015 jdk1.7.0_ 80lrwxrwxrwx  1 root root    11 dec 25 19:35 redis  -> redis-3.0.6drwxr-xr-x  4 root root    27 dec  25 19:38 redis-3.0.6drwxr-xR-x  2 root root   125 dec 31 18:20 toolslrwxrwxrwx   1 root root    15 Dec 25 01:29 zk03 ->  zookeeper-3.4.9drwxr-xr-x 12 1001  1001 4096 Dec 25 01:48  zookeeper-3.4.9[[email protected] opt]#

 5.3 Modify ports for all ACTIVEMQ consoles

Only the 118-row port is required [[email protected] conf]# pwd/opt/activemq01/conf[[email protected] conf]#  grep 8161 jetty.xml  118:      <property name= "Port"  value= "8161"/>[[email protected] conf]# grep -n  8161  Jetty.xml 118:        <property name= "Port"  value= " 8161 "/>[[email protected] conf]# [[email protected] conf]# grep -n  8162  jetty.xml 118:        <property name= " Port " value=" 8162 "/>135:                     <property name= "Port"  value= "8162"  />    #默认注释的端口   No tube [[Email protected] conf]# [[email protected] conf]# grep  -n  8163&Nbsp;jetty.xml 118:        <property name= "Port"   Value= "8163"/>[[email protected] conf]#

5.4 Modifying the name of the broker

VI Activemq.xml only need to modify Brokername= "dubboedu" default is localhost three changed to the same <broker xmlns= "http://activemq.apache.org/schema/ Core "brokername=" dubboedu "datadirectory=" ${activemq.data} ">

5.5 Modifying the port of the cluster communication and the LEVELDB storage mode

Content in <persistenceAdapter> in the  vim activemq.xml file   zk01:         <persistenceAdapter>               <replicatedLevelDB                   directory= "${activemq.data}/leveldb"    # Based on LEVELDB data storage path                    replicas= "3"     #复制的分片的个数   here are three                    bind= "tcp://0.0.0.0:62621"     #集群通讯的端口                    zkaddress= "192.168.56.51:2181,192.168.56.16:2181,192.168.56.17:2181"                    hostname= "Zk01"    #主机名                    zkpath= "/activemq/leveldb-stores"  # Path                 /in Zookeeper >        </persistenceAdapter>  zk02:       <persistenceAdapter>                   <replicatedLevelDB                          directory= "${activemq.data}/leveldb"                          replicas= "3"          &nbsP;               bind= "tcp:// 0.0.0.0:62622 "                         zkaddress= " 192.168.56.51:2181,192.168.56.16:2181,192.168.56.17:2181 "                         hostname= "zk02 "                         zkpath= "/activemq/leveldb-stores"                        />         </persistenceAdapter>           zk03:           <persistenceadapter>                 <replicatedLevelDB                   directory= "${activemq.data}/leveldb"                    replicas= "3"                    bind= "tcp:// 0.0.0.0:62623 "                   zkaddress= "192.168.56.51:2181,192.168.56.16:2181,192.168.56.17:2181"                    hostname= "Zk03"                    zkpath= "/ Activemq/leveldb-stores "/>        </persistenceadapter> 

5.6 Modifying the message port

  activemq.xml configuration file  zk01   [[email protected] conf]# grep   -n  51511 activemq.xml 120:             <transportconnector name= "Openwire"  uri= "tcp://0.0.0.0:51511?maximumconnections =1000&amp;wireformat.maxframesize=104857600 "/>[[email protected] conf]#   zk02     [[email protected] conf]# grep  -n 51512  activemq.xml 120:            < Transportconnector name= "Openwire"  uri= "tcp://0.0.0.0:51512?maximumconnections=1000&amp; wireformat.maxframesize=104857600 "/>[[email protected] conf]#  zk03  [[email  protected] conf]# grep -n  51513 activemq.xml 120:             <transportconnector name= "Openwire"  uri= "tcp://0.0.0.0:51513?maximumconnections=1000& amp;wireformat.maxframesize=104857600 "/>

6. Start Activemq

8 Testing high-availability ACTIVEMQ

8.1 Positive production three nodes:

8.2 At this point the activemq02 is in the master node and the master node is deactivated

To stop the master node activemq:[[email protected] bin]# ./activemq stop  view Message Queuing information, you can see the re-elected to the master node [ZK:  192.168.56.16:2181 (CONNECTED)  4] ls /activemq/leveldb-stores[00000000002,  00000000000][zk: 192.168.56.16:2181 (CONNECTED)  5] ls /activemq/leveldb-stores/00000000002[ ][zk: 192.168.56.16:2181 (CONNECTED)  6] get /activemq/leveldb-stores/00000000002{"id": " Dubboedu "," container ": null," address ": null," position ":-1," Weight ": 1," elected ":null}czxid =  0x400000012ctime = sat dec 31 19:33:44 cst 2016mzxid =  0x400000012mtime = sat dec 31 19:33:44 cst 2016pzxid =  0x400000012cversion = 0dataversion = 0aclversion = 0ephemeralowner =  0x259544b516a0000datalength = 89numchildren = 0[zk: 192.168.56.16:2181 (CONNECTED)  7] get /activemq/leveldb-stores/00000000000{"id":" dubboedu "," container ": null," Address ":" tcp://zk01:62621 "," position ":-1," Weight ": 1," elected ":" 0000000000 "} Czxid = 0x400000005ctime = sat dec 31 19:32:51 cst 2016mzxid  = 0x40000000dmtime = sat dec 31 19:33:17 cst 2016pzxid =  0x400000005cversion = 0dataversion = 4aclversion = 0ephemeralowner =  0x359544bcfbb0000
