RocketMQ 2主2从 集群搭建

安装环境

　　jdk1.7

　　alibaba-rocketmq-3.2.6.tar.gz

　　VM虚拟机redhat6.5-x64：192.168.1.201  192.168.1.202 192.168.1.203  192.168.1.204

　　Xshell4

部署方案

IP	主机名	用途	Broker角色
192.168.1.201	broker-a	NameServer，Broker	Master
192.168.1.202	broker-b	NameServer, Broker	Master
192.168.1.203	broker-a-s	NameServer, Broker	Slave
192.168.1.204	broker-b-s	NameServer, Broker	Slave

安装步骤：【两台机器同样操作  以201为例】

步骤一：解压安装文件alibaba-rocketmq-3.2.6.tar.gz

[root@ rocketmq]# tar -zxvf alibaba-rocketmq-3.2..tar.gz -C /usr/local
[root@ rocketmq]# mv alibaba-rocketmq rocketmq

步骤二：修改配置

　　配置一：创建存储路径 用于存储队列 索引 提交日志等信息

[root@ rocketmq]# mkdir -p /usr/local/rocketmq/store
[root@ rocketmq]# mkdir -p /usr/local/rocketmq/store/commitlog
[root@ rocketmq]# mkdir -p /usr/local/rocketmq/store/consumequeue
[root@ rocketmq]# mkdir -p /usr/local/rocketmq/store/index

配置二：Hosts添加信息

192.168.1.201 rocketmq-nameserver1
192.168.1.202 rocketmq-nameserver2
192.168.1.203 rocketmq-nameserver3
192.168.1.204 rocketmq-nameserver4
192.168.1.201 rocketmq-master1
192.168.1.202 rocketmq-master2
192.168.1.203 rocketmq-slave1
192.168.1.204 rocketmq-slave2

重启网卡：service network restart

相互ping一下，在201机器上ping 192.168.1.202   ping  rocketmq-nameserver2   ping  rocketmq-master2 。 202 203 204机器上也一样。

配置三：RocketMQ配置文件：

同步双写，配置目录：2m-2s-async

异步刷盘，配置目录：2m-2s-sync

vim /usr/local/rocketmq/conf/2m-2s-sync/broker-a.properties
#
vim /usr/local/rocketmq/conf/2m-2s-sync/broker-b.properties
#

#
vim /usr/local/rocketmq/conf/2m-2s-sync/broker-b-s.properties

#所属集群名字

# 表示 Master，> 表示 Slave

注意：
brokerName:
201 broker-a
202 broker-b
203 broker-a-s
204 broker-b-s

brokerId
201 202 是master 配置brokerId=0

203 204 是slave  配置brokerId=1

brokerRole
201 202是master 配置 brokerRole=SYNC_MASTER

203 204是slave配置 brokerRole=SLAVE

配置四：修改日志配置文件

[root@ conf]# mkdir -p /usr/local/rocketmq/logs
[root@ conf]# cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml

配置五：修改启动脚本参数 Xms和Xmx至少是1G  否则启动不起来  Xmn一般是前者的一半

vim /usr/local/rocketmq/bin/runbroker.sh
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"

vim /usr/local/rocketmq/bin/runserver.sh
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"

步骤三：启动：先启动两台机器的NameServer，再启动两台机器的Borker，关机的时候顺序相反，先关闭两台机器的Broker，再关闭两台机器的Nameserver。在启动 BrokerServer 之前先关闭防火墙.

启动一：NameServer
cd /usr/local/rocketmq/bin
nohup sh mqnamesrv &
#查看进程
jps
#查看日志
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log

#启动二：BrokerServer A 192.168.1.201
cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null >& &
netstat -ntlp
jps
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/broker.log
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log 

#启动三：BrokerServer B 192.168.1.202
cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null >& &
netstat -ntlp
jps
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/broker.log
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log

#启动四：BrokerServer B 192.168.1.203
cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a-s.properties >/dev/null >& &
netstat -ntlp
jps
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/broker.log
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log

#启动五：BrokerServer B 192.168.1.204
cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b-s.properties >/dev/null >& &
netstat -ntlp
jps
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/broker.log
tail -f -n  /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log
