RocketMQ分布式消息中间件-Centos7安装运行

RocketMQ分布式消息中间件-Centos7安装运行

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

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

# 安装方式二:源码编译运行

  • 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1

  • 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

runbroker.sh

同理,将默认的8g调整为合适的大小,我这里也给了256m

JAVA_OPT="${JAVA_OPT} -XX:MaxDirectMemorySize=15g"

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。
