RocketMQ部署文档

1、整体规划

IP	HOSTNAME	用户	角色	模式
137.32.117.11	rocketmq-master1	root	nameServer1，brokerServer1	Master1
137.32.117.12	rocketmq-master2	root	nameServer1，brokerServer2	Master2

/etc/hosts主机映射
137.32.117.11	rocketmq-nameserver1
137.32.117.11	rocketmq-master1
137.32.117.12	rocketmq-nameserver2
137.32.117.12	rocketmq-master2

2、环境准备

• 修改hosts文件添加主机映射

  root@localhost ~]# vi /etc/hosts
  137.32.117.11 rocketmq-nameserver1
  137.32.117.11 rocketmq-master1
  137.32.117.12 rocketmq-nameserver2
  137.32.117.12 rocketmq-master2
  

• ping映射名称验证是否更改成功

  [root@localhost ~]# ping rocketmq-master2
  PING rocketmq-master2 (137.32.117.12) 56(84) bytes of data.
  64 bytes from rocketmq-nameserver2 (137.32.117.12): icmp_seq=1 ttl=64 time=0.011 ms
  64 bytes from rocketmq-nameserver2 (137.32.117.12): icmp_seq=2 ttl=64 time=0.020 ms
  

• 安装jdk

  • 上传安装包，解压

    [root@localhost usr]# mkdir java
    [root@localhost java]# tar -zxvf jdk-8u181-linux-x64.tar.gz -C /usr/java
    [root@localhost java]# pwd
    /usr/java
    [root@localhost java]# ls
    jdk1.8.0_181  jdk-8u181-linux-x64.tar.gz
    

  • 修改/etc/profile文件

    [root@localhost java]# vim /etc/profile
    # 添加下面三行
    export JAVA_HOME=/usr/java/jdk1.8.0_181
    export CLASSPATH=.:${JAVA_HOME}/jre/lib/rt.jar:${JAVA_HOME}/lib/dt.jar:${JAVA_HOME}/lib/tools.jar
    export PATH=$PATH:${JAVA_HOME}/bin
    

  • 重新加载配置文件，并验证

    [root@localhost java]# source /etc/profile
    [root@localhost java]# java -version
    java version "1.8.0_181"
    Java(TM) SE Runtime Environment (build 1.8.0_181-b13)
    Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
    

3、修改配置文件

• 解压重命名

  [root@localhost local]# tar -zxvf alibaba-rocketmq-3.2.6.tar.gz 
  [root@localhost local]# ls
  alibaba-rocketmq  alibaba-rocketmq-3.2.6.tar.gz  bin  etc  games  include  lib  lib64  libexec  sbin  share  src
  [root@localhost local]# mv alibaba-rocketmq rocketmq
  [root@localhost local]# ls
  alibaba-rocketmq-3.2.6.tar.gz  bin  etc  games  include  lib  lib64  libexec  rocketmq  sbin  share  src
  
  

• 创建存储路径

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

• 修改日志配置文件

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

• 修改启动脚本参数

  [root@localhost bin]# vi /usr/local/rocketmq/bin/runbroker.sh
  JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"
  [root@localhost bin]# vi /usr/local/rocketmq/bin/runserver.sh
  JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"
  

4、启动

• 启动nameserver

  [root@localhost java]# cd /usr/local/rocketmq/bin
  [root@localhost bin]# nohup sh mqnamesrv &
  [1] 1837
  [root@localhost bin]# nohup: ignoring input and appending output to ‘nohup.out’
  
  [root@localhost bin]# 
  

• 启动brokerServer A，在11主机

  [root@localhost bin]# cd /usr/local/rocketmq/bin
  [root@localhost bin]# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &
  [2] 1867
  [root@localhost bin]# jps
  1874 BrokerStartup
  1843 NamesrvStartup
  1934 Jps
  
  
  # 查看启动日志
  [root@localhost bin]# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/namesrv.log
  [root@localhost bin]# tail -f -n 500 /usr/local/rocketmq/logs/rocketmqlogs/broker.log
  

• 启动brokerServer B，在12主机

  [root@localhost bin]# cd /usr/local/rocketmq/bin
  [root@localhost bin]# nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null 2>&1 &
  

• 停应用

  [root@localhost bin]# cd /usr/local/rocketmq/bin
  [root@localhost bin]# sh mqshutdown broker
  [root@localhost bin]# sh mqshutdown namesrv
