RocketMQ安装过程遇到的坑以及解决方案

周末,按照网上教程安装了rocketMQ集群,期间遇到一些小问题,导致耽误不少时间

记录下来

本文只涉及安装过程,原理不涉及

下图是环境要求

![18824][]

环境:

centos 6 64位

jdk:1.8

rocketMQ版本:4.3.2

模式:两 master 两 slave 同步双写模式

IP 部署服务 角色

192.168.168.101 NameServer –

192.168.168.102 NameServer –

192.168.168.101 broker-a master

192.168.168.101 broker-b-s slave

192.168.168.102 broker-b master

192.168.168.102 broker-a-s slave

1.首先安装好jdk并配置好环境变量(其它文章有,不再详述)

2.下载安装rocketMQ

不要选择先配置一个机器,直接拷贝到第二台机器这种方式!!!

要配置好第一个,再去配置第二个,因为总共就两台,直接复制容易出错(当然熟练的也可以复制后修改文件内容和文件名,初学者还是一步一个脚印)

官网下载链接:[http://mirror.bit.edu.cn/apache/rocketmq/4.3.2/rocketmq-all-4.3.2-bin-release.zip][http_mirror.bit.edu.cn_apache_rocketmq_4.3.2_rocketmq-all-4.3.2-bin-release.zip]

2.1下载后解压(两台机器都需要下载解压,如果linux没有安装.zip格式解压压缩软件的话,安装一个,安装命令:yum -y install zip unzip)

![18835][]

![18833][]

2.1.1解压后配置rocketMQ环境变量(两台都需要配置)

命令:vi /etc/profile

追加如下内容:

\#set rocketMQ environment

export ROCKETMQ\_HOME=/usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release

export PATH=$PATH:$ROCKETMQ\_HOME/bin

![18990][]

使修改生效

命令:source /etc/profile

![18999][]

2.1.2修改rocketMQ内存配置(两台都需要修改)

进入到rocketMQ的bin目录修改

命令:vi runserver.sh

将内存修改如下(默认分别是4g 8g,如果电脑配置达到那么高可以不用修改,否则启动不了,提示内存不足)

![19006][]

命令:vi runbroker.sh

将内存修改如下

![19012][]

2.2配置

2.2.1先配置192.168.168.101这台机器

2.2.2.3上面配置中用到了几个目录,需要创建下目录

命令:mkdir -p /usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release/data/store/slave/commitlog

![18912][]

3.启动

3.1先启动192.168.168.101

3.1.1启动nameserver

进入到rocketMQ的bin目录

命令:cd ../../bin

![18921][]

看一下都有什么命令

命令:ll

![18925][]

启动nameserver

命令:nohup sh mqnamesrv &

![18931][]

3.1.2启动broker-a Master

命令:nohup sh mqbroker -c /usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release/conf/2m-2s-sync/broker-a.properties &

![18935][]

3.1.3启动broker-b Slave

命令:nohup sh mqbroker -c /usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release/conf/2m-2s-sync/broker-b-s.properties &

![18939][]

3.2启动启动192.168.168.102

3.2.1启动nameserver

进入到rocketMQ的bin目录

cd ../../bin

![18952][]

启动nameserver

命令:nohup sh mqnamesrv &

![18960][]

3.2.2启动broker-b Master

命令:

nohup sh mqbroker -c /usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release/conf/2m-2s-sync/broker-b.properties &

![18970][]

3.2.3启动broker-a Slave

命令:

nohup sh mqbroker -c /usr/local/src/rocketmq/rocketmq-all-4.3.2-bin-release/conf/2m-2s-sync/broker-a-s.properties &

![18973][]

4.查看状态

进入192.168.168.101的rocketMQ的bin目录后输入命令查看集群状态(进入到192.168.168.102的bin目录输入下面的命令效果一样;将rocketmq的bin配置到path后任意目录输入下面的命令均可)

命令:sh mqadmin clusterlist -n 192.168.168.101:9876

![18982][]

5.遇到的坑

坑1:

其实不算坑

就是安装的时候先安装好一个,另外一个直接scp复制第一个安装目录到第二台机器导致的问题

所以,不熟练的时候,一定要一个安装好再安装另一个,以防止出错,不要眼高手低,犯低级错误!

坑2.直接将Master的配置复制到Slave,只修改brokerId

这样会导致Slave无法启动,因为Slave的storePathRootDir会和另一个broker的Master冲突,错误提示是:lock failed, MQ already started

这个只需要保证Master和Slave的storePathRootDir不一样即可(broker-x 的Slave和broker-y的Master不能一致,本例中broker-a的Master不能和broker-b Slave一样)

6.可以使用rocketmq-console来更直观查看rocketmq信息

![19052][]

把rocketmq-console的war包放在192.168.168.101的tomcat下,启动tomcat即可

访问地址:[http://192.168.168.101:8080/rocketmq\_console-0.0.1-SNAPSHOT][http_192.168.168.101_8080_rocketmq_console-0.0.1-SNAPSHOT]

war包地址:[https://note.youdao.com/share/?id=34a49baab8606ac2cde7533e395afb1c&type=note\#/][https_note.youdao.com_share_id_34a49baab8606ac2cde7533e395afb1c_type_note](由于百度云上传下载太慢,放了一个有道云笔记的分享链接,下载很快,该war包是下载的源码,但是源码无法导入eclipse,所以新建的项目,将源码中内容加入后打包的)
