activemq+zookeeper 集群部署基于levedb
集群图
zookeeper集群，上一篇博客写了zookeeper集群的部署
Ip 服务注册端口 主机名 192.168.56.15 2181 zk01 192.168.56.16 2181 zk02 192.168.56.17 2181 zk03 activemq部署
IP 管控台端口 集群通讯端口 消息端口 192.168.56.15 8161 61621 51511 192.168.56.16 8162 61622 51512 192.168.56.17 8163 61623 51513 host解析必须做
[root@zk03 conf]# cat /etc/hosts 192.168.56.15 zk01 192.168.56.16 zk02 192.168.56.17 zk03
5.
5.1 zookeeper 集群不在配置，参看前面博客
5.2 activemq 安装包
说明：zk03 是zookeeper的 activemq03 是activemq的 jdk 是java环境 redis不用管 三台机器全部部署 [root@zk03 opt]# pwd /opt [root@zk03 opt]# ll total 12 lrwxrwxrwx 1 root root 21 Dec 31 18:20 activemq03 -> apache-activemq-5.9.0 drwxr-xr-x 10 501 games 4096 Oct 15 2013 apache-activemq-5.9.0 lrwxrwxrwx 1 root root 11 Dec 25 01:27 jdk -> jdk1.7.0_80 drwxr-xr-x 8 10 143 4096 Apr 11 2015 jdk1.7.0_80 lrwxrwxrwx 1 root root 11 Dec 25 19:35 redis -> redis-3.0.6 drwxr-xr-x 4 root root 27 Dec 25 19:38 redis-3.0.6 drwxr-xr-x 2 root root 125 Dec 31 18:20 tools lrwxrwxrwx 1 root root 15 Dec 25 01:29 zk03 -> zookeeper-3.4.9 drwxr-xr-x 12 1001 1001 4096 Dec 25 01:48 zookeeper-3.4.9 [root@zk03 opt]#
5.3 修改所有activemq管控台的端口
只需要该118行的端口 [root@zk01 conf]# pwd /opt/activemq01/conf [root@zk01 conf]# grep 8161 jetty.xml 118： <property name="port" value="http://www.mamicode.com/8161"/> [root@zk01 conf]# grep -n 8161 jetty.xml 118: <property name="port" value="http://www.mamicode.com/8161"/> [root@zk01 conf]# [root@zk02 conf]# grep -n 8162 jetty.xml 118: <property name="port" value="http://www.mamicode.com/8162"/> 135: <property name="port" value="http://www.mamicode.com/8162" /> #默认注释的端口 不用管 [root@zk02 conf]# [root@zk03 conf]# grep -n 8163 jetty.xml 118: <property name="port" value="http://www.mamicode.com/8163"/> [root@zk03 conf]#
5.4 修改broker的名称
vi activemq.xml
只需要修改brokerName="dubboedu" 默认是localhost
三台改成一样的
<broker xmlns="http://activemq.apache.org/schema/core" brokerName="dubboedu" dataDirectory="${activemq.data}">5.5 修改集群通讯的端口以及leveldb存储模式
vim activemq.xml文件中<persistenceAdapter>中的内容
zk01：
<persistenceAdapter>
<replicatedLevelDB
directory="${activemq.data}/leveldb" #基于leveldb数据存放路径
replicas="3" #复制的分片的个数 这里是三台
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" #zookeeper中的路径
/>
</persistenceAdapter>
zk02:
<persistenceAdapter>
<replicatedLevelDB
directory="${activemq.data}/leveldb"
replicas="3"
bind="tcp://0.0.0.0:62622"
zkAddress="192.168.56.51:2181,192.168.56.16:2181,192.168.56.17:2181"
hostname="zk02"
zkPath="/activemq/leveldb-stores"
/>
</persistenceAdapter>
zk03:
<persistenceAdapter>
<replicatedLevelDB
directory="${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 修改消息端口
activemq.xml配置文件 zk01 [root@zk01 conf]# grep -n 51511 activemq.xml 120: <transportConnector name="openwire" uri="tcp://0.0.0.0:51511?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> [root@zk01 conf]# zk02 [root@zk02 conf]# grep -n 51512 activemq.xml 120: <transportConnector name="openwire" uri="tcp://0.0.0.0:51512?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/> [root@zk02 conf]# zk03 [root@zk03 conf]# grep -n 51513 activemq.xml 120: <transportConnector name="openwire" uri="tcp://0.0.0.0:51513?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
6.启动activemq
zookeeper一定要提前启动 顺序启动activemq [root@zk01 bin]# /opt/activemq01/bin/activemq start INFO: Using default configuration (you can configure options in one of these file: /etc/default/activemq /root/.activemqrc) INFO: Invoke the following command to create a configuration file /opt/activemq01/bin/activemq setup [ /etc/default/activemq | /root/.activemqrc ] INFO: Using java ‘/opt/jdk/bin/java‘ INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details INFO: pidfile created : ‘/opt/activemq01/data/activemq-zk01.pid‘ (pid ‘4541‘) [root@zk02 conf]# /opt/activemq02/bin/activemq start INFO: Using default configuration (you can configure options in one of these file: /etc/default/activemq /root/.activemqrc) INFO: Invoke the following command to create a configuration file /opt/activemq02/bin/activemq setup [ /etc/default/activemq | /root/.activemqrc ] INFO: Using java ‘/opt/jdk/bin/java‘ INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details INFO: pidfile created : ‘/opt/activemq02/data/activemq-zk02.pid‘ (pid ‘4492‘) [root@zk02 conf]# [root@zk03 conf]# /opt/activemq03/bin/activemq start INFO: Using default configuration (you can configure options in one of these file: /etc/default/activemq /root/.activemqrc) INFO: Invoke the following command to create a configuration file /opt/activemq03/bin/activemq setup [ /etc/default/activemq | /root/.activemqrc ] INFO: Using java ‘/opt/jdk/bin/java‘ INFO: Starting - inspect logfiles specified in logging.properties and log4j.properties to get details INFO: pidfile created : ‘/opt/activemq03/data/activemq-zk03.pid‘ (pid ‘2296‘)
7.查看分片以及zookeeper的信息
登录任意一台zookeeper就行
[root@zk02 bin]# pwd
/opt/zk02/bin
[root@zk02 bin]# ./zkCli.sh -server 192.168.56.16:2181
[zk: 192.168.56.16:2181(CONNECTED) 0] ls /
[activemq, dubbo, zookeeper]
[zk: 192.168.56.16:2181(CONNECTED) 1] ls /activemq
[leveldb-stores]
[zk: 192.168.56.16:2181(CONNECTED) 2] ls /activemq/leveldb-stores
[00000000002, 00000000001, 00000000000]
[zk: 192.168.56.16:2181(CONNECTED) 3]
elected值不为空的是消息activemq的master节点
[zk: 192.168.56.16:2181(CONNECTED) 3] get /activemq/leveldb-stores/00000000002
{"id":"dubboedu","container":null,"address":null,"position":-1,"weight":1,"elected":null}
cZxid = 0x400000012
ctime = Sat Dec 31 19:33:44 CST 2016
mZxid = 0x400000012
mtime = Sat Dec 31 19:33:44 CST 2016
pZxid = 0x400000012
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x259544b516a0000
dataLength = 89
numChildren = 0
[zk: 192.168.56.16:2181(CONNECTED) 4] get /activemq/leveldb-stores/00000000001
{"id":"dubboedu","container":null,"address":null,"position":-1,"weight":1,"elected":null}
cZxid = 0x400000008
ctime = Sat Dec 31 19:33:16 CST 2016
mZxid = 0x400000015
mtime = Sat Dec 31 19:33:45 CST 2016
pZxid = 0x400000008
cversion = 0
dataVersion = 8
aclVersion = 0
ephemeralOwner = 0x359544bcfbb0001
dataLength = 89
numChildren = 0
[zk: 192.168.56.16:2181(CONNECTED) 5] get /activemq/leveldb-stores/00000000000
{"id":"dubboedu","container":null,"address":"tcp://zk01:62621","position":-1,"weight":1,"elected":"0000000000"}
cZxid = 0x400000005
ctime = Sat Dec 31 19:32:51 CST 2016
mZxid = 0x40000000d
mtime = Sat Dec 31 19:33:17 CST 2016
pZxid = 0x400000005
cversion = 0
dataVersion = 4
aclVersion = 0
ephemeralOwner = 0x359544bcfbb0000
dataLength = 111
numChildren = 0
[zk: 192.168.56.16:2181(CONNECTED) 6]8 测试高可用activemq
8.1 正产三个节点：
[zk: 192.168.56.16:2181(CONNECTED) 3] ls /activemq/leveldb-stores [00000000002, 00000000001, 00000000000] [zk: 192.168.56.16:2181(CONNECTED) 4]
8.2 此时activemq02处于主节点，停掉主节点
停掉主节点activemq：
[root@zk02 bin]# ./activemq stop
查看消息队列的信息，可以看出重新选出来主节点
[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 = 0x400000012
ctime = Sat Dec 31 19:33:44 CST 2016
mZxid = 0x400000012
mtime = Sat Dec 31 19:33:44 CST 2016
pZxid = 0x400000012
cversion = 0
dataVersion = 0
aclVersion = 0
ephemeralOwner = 0x259544b516a0000
dataLength = 89
numChildren = 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 = 0x400000005
ctime = Sat Dec 31 19:32:51 CST 2016
mZxid = 0x40000000d
mtime = Sat Dec 31 19:33:17 CST 2016
pZxid = 0x400000005
cversion = 0
dataVersion = 4
aclVersion = 0
ephemeralOwner = 0x359544bcfbb00008.3 启动activemq02
[root@zk02 bin]# ./activemq start 查看消息队列的信息 [zk: 192.168.56.16:2181(CONNECTED) 8] ls /activemq/leveldb-stores [00000000003, 00000000002, 00000000000] #重新加进来 [zk: 192.168.56.16:2181(CONNECTED) 9]
8.5java代码链接activemq
java conf 消息队列的配置文件
failover:(tcp://192.168.56.15:51511,tcp://192.168.56.16:51512.tcp://192.168.56.17:51513)?random=false mq.username=admin my.password=admin #这是消息队列的用户名和密码 生产场景自己修改 mq.pool.maxConnection=10 queueName=队列的名称
9.开机自动启动不要忘了做了！！
