RocketMQ 安装

RocketMQ 安装

记录如何安装rocketMQ 以及使用service脚本进行管理

注意:请确保当前机器上安装了JDK 并且有JAVA_HOME 环境变量

一、RocketMQ 下载安装

  1. 从官网上下载最新安装包，下载完成后并解压到/opt 目录中

    [root@VM-4-14-centos ~] tar -zxvf rocketmq-4.9.3.tar.gz -C /opt/

  2. 修改runbroker.sh、runserver.sh 将其中的去掉-Xms参数，避免内存不足无法启动

    2

  3. 创建rocketmq 用户，并进行建立软链接参数

    [root@VM-4-14-centos bin] useradd -r -M rocketmq  # 创建rocketmq用户
[root@VM-4-14-centos bin] ln -s /opt/rocketmq-4.9.3/ /usr/local/rocketmq # 建立软链接
[root@VM-4-14-centos rocketmq] echo 'export PATH=/usr/local/rocketmq/bin:$PATH' >> /etc/profile && source /etc/profile # 加入path环境变量

  4. 将rocketmq.sh 文件放到rocketmq bin目录下，并修改权限

    [root@VM-4-14-centos bin] mv /root/rocketmq.sh /usr/local/rocketmq/bin/ 
[root@VM-4-14-centos bin] chown rocketmq:rocketmq -R /usr/local/rocketmq/ #修改文件所有者
[root@VM-4-14-centos bin] chmod +x -R /usr/local/rocketmq/bin/

  5. 将rockemq service 脚本复制到 /etc/init.d/ 目录下

    [root@VM-4-14-centos ~] cp /root/rocketmq /etc/init.d/
[root@VM-4-14-centos ~] chmod +x /etc/init.d/rocketmq # 增加执行权限
[root@VM-4-14-centos ~] chkconfig rocketmq # 服务自启动

二、RocketMQ 启动测试

  1. 输入service rocketmq start 启动rocketMQ

    [root@VM-4-14-centos ~] service rocketmq start # rocketmq 启动
 Starting RocketMQ... 
Name Server Start Success
Broker Start Success
 Start RocketMQ  ...............................  [OK]

  2. 输入service rocketmq status 查看rocketMQ 状态

    [root@VM-4-14-centos bin] service rocketmq status
 Broker is running on 27614   
 NameServer is running on 27570

三、问题排查

如果出现问题可以查看rockeMQ 的日志

  1. 进入/usr/local/rocketmq/log 目录下，查看rocketMQ 日志，所有日志以日期为单位进行分割

四、附录

  1. rocketmq.sh 脚本

    #!/bin/bash
# this is rocketmq start stop script
FRONT="\033[34;49;1m"
BACK="\033[39;49;0m"
# 应用目录
ROCKETMQ_HOME=${ROCKETMQ_HOME:-/usr/local/rocketmq}
# () 括号可以用于命令执行结果,即将该命令执行结果作为参数传给变量
TODAY=$(date +%y%m%d)
IP=$(ip addr | awk '/^[0-9]+: / {}; /inet.*global/ {print gensub(/(.*)\/(.*)/, "\\1", "g", $2)}')

start_server () {
  cd ${ROCKETMQ_HOME}
  nohup sh $ROCKETMQ_HOME/bin/mqnamesrv 1>${ROCKETMQ_HOME}/log/rocketmq_nameserver_${TODAY}.log 2>&1 &
  SERVER_PID="$!"

  if [[ $? != 0 ]]; then
    echo -e "${FRONT}Name Server Start Failed${BACK}"
    exit 2
  else
    echo -e "${FRONT}Name Server Start Success${BACK}"  
  fi

}

start_broker () {
  cd ${ROCKETMQ_HOME}
  nohup sh $ROCKETMQ_HOME/bin/mqbroker -n ${IP}:9876 -c $ROCKETMQ_HOME/conf/broker.conf >${ROCKETMQ_HOME}/log/rocketmq_broker_${TODAY}.log 2>&1 &
  BROKER_PID="$!"

  if [[ $? != 0 ]]; then
    echo -e "${FRONT}Broker Start Failed${BACK}"
    exit 2
  else
    echo -e "${FRONT}Broker Start Success${BACK}"  
  fi

}

do_stop () {
  cd ${ROCKETMQ_HOME}
  if [[ -f $ROCKETMQ_HOME/bin/mqshutdown ]]; then

    sh ./bin/mqshutdown namesrv >> ${ROCKETMQ_HOME}/log/rocketmq_shutdown_${TODAY}.log
    sleep  2s
    sh ./bin/mqshutdown broker >> ${ROCKETMQ_HOME}/log/rocketmq_shutdown_${TODAY}.log

    if [[ $? = 0 ]]; then
    echo -e "${FRONT}stop success${BACK}"
    fi

  else
    echo -e "${FRONT}no stop script,exit${BACK}"
    exit 2
  fi
}

do_status () {
  STATUS1=$(jps | grep BrokerStartup)
  if [[ ${STATUS1} != "" ]]; then
    echo -e "$FRONT Broker is running on $(echo ${STATUS1} | sed "s/BrokerStartup/""/g") $BACK " 
  else
    echo -e "$FRONT Broker NOT RUNNING $BACK "
  fi

  STATUS2=$(jps | grep NamesrvStartup)
  if [[ ${STATUS2} != "" ]]; then
    echo -e "$FRONT NameServer is running on $(echo ${STATUS2} | sed "s/NamesrvStartup/""/g") $BACK "
  else
    echo -e "$FRONT NameServer NOT RUNNING $BACK "
  fi

}

do_start (){
  start_server
  sleep 1 
  start_broker
}

case "$1" in
  start)
    do_start
  ;;
  stop)
    do_stop
  ;;
  restart)
    do_stop
   # 由于broker 在停止时是不会立即退出的，所以此处需要将sleep时间略微长一点,如果2s不足可以再延长些
    sleep 2
    do_start
  ;;
  status)
    do_status
  ;;
  *)
    echo "$0 <start|stop|restart|status> [id]"
  ;;
