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
<hr/>
文档及代码
- Apache 上开源官方地址:https://rocketmq.apache.org/
- GitHub 托管地址:https://github.com/apache/rocketmq
- 阿里官方的介绍文档:http://jm.taobao.org/2017/01/12/rocketmq-quick-start-in-10-minutes/
- Apache 官方提供的 “快速入门” 文档:https://rocketmq.apache.org/docs/quick-start/
- RocketMQ的运行方式非常简单,这里简单记录一下步骤,最主要的还是记录安装运行过程中踩过的坑
- 该篇介绍两种运行方式,均参照官方文档操作,以当前最新4.5.0版本为例,所有操作均在
/root
目录进行
<hr/>
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
> 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
> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK
> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK
<hr/>
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:
drwxr-xr-x 3 root root 4096 Mar 29 13:20 acl drwxr-xr-x 3 root root 4096 Mar 29 13:20 broker -rw-r--r-- 1 root root 997 Mar 29 13:20 BUILDING drwxr-xr-x 3 root root 4096 Mar 29 13:20 client drwxr-xr-x 3 root root 4096 Mar 29 13:20 common -rw-r--r-- 1 root root 1997 Mar 29 13:20 CONTRIBUTING.md -rw-r--r-- 1 root root 271 Mar 29 13:20 DEPENDENCIES drwxr-xr-x 2 root root 4096 Mar 29 13:20 dev drwxr-xr-x 5 root root 4096 Mar 29 13:20 distribution drwxr-xr-x 4 root root 4096 Mar 29 13:20 docs drwxr-xr-x 3 root root 4096 Mar 29 13:20 example drwxr-xr-x 3 root root 4096 Mar 29 13:20 filter -rw-r--r-- 1 root root 11365 Mar 29 13:20 LICENSE drwxr-xr-x 3 root root 4096 Mar 29 13:20 logappender drwxr-xr-x 3 root root 4096 Mar 29 13:20 logging drwxr-xr-x 3 root root 4096 Mar 29 13:20 namesrv -rw-r--r-- 1 root root 168 Mar 29 13:20 NOTICE drwxr-xr-x 3 root root 4096 Mar 29 13:20 openmessaging -rw-r--r-- 1 root root 23992 Mar 29 13:20 pom.xml -rw-r--r-- 1 root root 2521 Mar 29 13:20 README.md drwxr-xr-x 3 root root 4096 Mar 29 13:20 remoting drwxr-xr-x 3 root root 4096 Mar 29 13:20 srvutil drwxr-xr-x 3 root root 4096 Mar 29 13:20 store drwxr-xr-x 3 root root 4096 Mar 29 13:20 style drwxr-xr-x 3 root root 4096 Mar 29 13:20 test drwxr-xr-x 3 root root 4096 Mar 29 13:20 tools
- 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

- 进入编译后的目录:
cd distribution/target/apache-rocketmq
看到以下目录结构
drwxr-xr-x 2 root root 4096 Apr 8 17:53 benchmark drwxr-xr-x 3 root root 4096 Mar 29 13:20 bin drwxr-xr-x 6 root root 4096 Mar 29 13:20 conf drwxr-xr-x 2 root root 4096 Apr 8 17:53 lib -rw-r--r-- 1 root root 17336 Mar 29 13:20 LICENSE -rw-r--r-- 1 root root 1337 Mar 29 13:20 NOTICE -rw-r--r-- 1 root root 2521 Mar 29 13:20 README.md0
- 到这里源码编译完成,下面的步骤跟二进制运行方式一样,请查看二进制运行方式

采坑记录
内存分配失败
Java HotSpot(TM) 64-Bit Server VM warning: INFO: os::commit_memory(0x00000005c0000000, 8589934592, 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 8589934592 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_pid17515.log
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

以上只是我个人在安装运行过程中的一些记录和遇到的坑,如有不完善的地方欢迎指出,我也会在文中继续补充完善。
