本文字数： 9k 阅读时长 ≈ 8 分钟

消息队列作为高并发系统的核心组件之一，能够帮助业务系统解构提升开发效率和系统稳定性。最近公司的项目也是用上了RocketMQ，所以这里记录一下RocketMQ环境安装部署过程。

环境准备

我们假设你已经设置好如下环境，没有的先自行安装环境，这里不做展开

  • Centos7：我这里用的是阿里云服务器，Centos7，内核：3.10.0-693.2.2.el7.x86_64
  • JDK1.8：JDK版本：JDK_1.8.0_201_64-Bit
  • Maven：Apache Maven 3.6.0
  • unzip：解压工具，用来解压安装包，没有该工具可直接使用 yum install unzip -y 安装
# 文档及代码
# 安装方式一：二进制直接运行

  • 二进制文件：http://mirrors.shu.edu.cn/apache/rocketmq/4.5.0/rocketmq-all-4.5.0-bin-release.zip

  • 下载二进制文件：wget http://mirrors.shu.edu.cn/apache/rocketmq/4.5.0/rocketmq-all-4.5.0-bin-release.zip

  • 解压：unzip rocketmq-all-4.5.0-bin-release.zip

  • 进入解压后的二进制文件目录：cd rocketmq-all-4.5.0-bin-release

  • 看到以下目录结构：

    drwxr-xr-x 2 root root  4096 Mar 29 17:37 benchmark
    drwxr-xr-x 3 root root  4096 Mar 29 17:37 bin
    drwxr-xr-x 6 root root  4096 Mar 29 17:37 conf
    drwxr-xr-x 2 root root  4096 Mar 29 17:37 lib
    -rw-r--r-- 1 root root 17336 Mar 28 19:52 LICENSE
    -rw-r--r-- 1 root root  1337 Mar 28 19:53 NOTICE
    -rw-r--r-- 1 root root  2521 Mar 28 19:53 README.md

    启动NameServer服务

  • 后台启动Name Server服务：nohup sh bin/mqnamesrv &

  • 查看启动日志：tail -f ~/logs/rocketmqlogs/namesrv.log

这里如果你的系统配置如果不够高那么你可能会遇到如下错误：

Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000006ec800000, 2147483648, 0) failed; error='Cannot allocate memory' (errno=12)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 2147483648 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /root/rocketmq-all-4.5.0-bin-release/hs_err_pid16614.log

日志已经提示出来了，你也可以打开日志文件查看详细信息：tail -f ~/logs/rocketmqlogs/broker.log

这里的报错是因为内存分配失败，解决方法请往下翻到第五节查看。

启动Broker服务

  • 后台启动Broker服务：nohup sh bin/mqbroker -n localhost:9876 &

  • 查看启动日志：tail -f ~/logs/rocketmqlogs/broker.log

这里同样可能会遇到内存分配失败的错误

运行消息生产者测试

> export NAMESRV_ADDR=localhost:9876
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
SendResult [sendStatus=SEND_OK, msgId= ...

运行消息消费者测试

1
2
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
ConsumeMessageThread_%d Receive New Messages: [MessageExt...

两项测试如果均运行成功那么RocketMQ服务安装没什么问题了

关闭服务

# 安装方式二：源码编译运行

下载及编译

  • 源代码地址：http://mirrors.shu.edu.cn/apache/rocketmq/4.5.0/rocketmq-all-4.5.0-source-release.zip

  • 下载源码：wget http://mirrors.shu.edu.cn/apache/rocketmq/4.5.0/rocketmq-all-4.5.0-source-release.zip

  • 解压：unzip rocketmq-all-4.5.0-source-release.zip

  • 进入解压后的源码目录：cd rocketmq-all-4.5.0

  • 可以看到有如下文件：

  • 执行mvn命令编译：mvn -Prelease-all -DskipTests clean install -U，该过程可能会下载若干依赖，耐心等待即可

  • 有如下显示表示编译成功

遇到这个错误，请修改 bin 目录下的 runserver.sh 和 runbroker.sh 这两个文件：

runserver.sh

将默认的4g调整为合适的大小，我这里给了256m
