RocketMQ安装配置过程

官网

Linux+JDK1.8

服务器配置

1. 服务器内配置JDK环境，将压缩包上传到/usr/local下进行解压

tar -zxvf jdk-8u231-linux-x64.tar.gz /usr/local

1. 配置环境变量

vim /etc/profile

#插入内容
export JAVA_HOME=/usr/local/jdk1.8.0_231
export JRE_HOME=$JAVA_HOME/jre
export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib
export PATH=$JAVA_HOME/bin:$PATH

#即时生效
source /etc/profile

1. 在Windows上进入rocketmq主目录使用maven编译项目

mvn -Prelease-all -DskipTests clean install -U

编译后在这个文件夹找到压缩包

D:\config\apache-maven-3.6.2\Repository\org\apache\rocketmq\rocketmq-distribution\4.3.2

1. 将编译好的压缩包上传到Linux系统中解压

#创建rocketmq目录
mkdir /usr/local/rocketmq

#解压rocketmq压缩包
tar -zxvf rocketmq-distribution-4.3.2.tar.gz -C /usr/local/rocketmq

1. 运行rocketmq

#进入/usr/local/rocketmq/bin目录
cd /usr/local/rocketmq/bin

#修改配置文件runserver.sh与runbroker.sh启动参数
#JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m"

#执行mqnamesrv
./mqnamesrv

#执行runbroker
./mqbroker -n localhost:9876

控制台rocketmq-console编译安装

上传到服务器并解压缩

编译

进入rocketmq-console目录

执行编译

mvn clean package -Dmaven.test.skip=true

启动

编译成功后在rocketmq-console/target目录下执行rocketmq-console-ng-1.0.1.jar

启动时，直接动态添加nameserver地址或编辑application.properties添加属性

java -jar rocketmq-console-ng-1.0.1.jar --rocketmq.config.namesrvAddr=127.0.0.1:9876

编译时包无法在mirror上找到 提示502错误

原因：网络不好或maven仓库服务器出错

重试即可，或者换一个镜像仓库

发送失败提示connect to null failed

./tools.sh org.apache.rocketmq.example.quickstart.Producer
22:49:02.470 [main] DEBUG i.n.u.i.l.InternalLoggerFactory - Using SLF4J as the default logging framework
RocketMQLog:WARN No appenders could be found for logger (io.netty.util.internal.PlatformDependent0).
RocketMQLog:WARN Please initialize the logger system properly.
java.lang.IllegalStateException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to
null failed

原因：不知道nameserver在哪儿

在tools脚本中添加

export NAMESRV_ADDR=localhost:9876

启动broker失败 Cannot allocate memory

原因：jvm启动初始化内存分配大于物理内存

[root@node-113b bin]# ./mqbroker -n localhost:9876
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:
# /usr/local/rocketmq/bin/hs_err_pid1997.log

修改启动脚本中的jvm参数

runbroker.sh broker

runserver.sh nameserver

默认数值给的都很大，改小即可

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=64m -XX:MaxMetaspaceSize=100m"

启动broker成功但提示：Failed to obtain the host name

原因：无法解析当前的主机名

hosts里添加映射即可
