RocketMQ安装配置过程


官网

官方网站:http://rocketmq.apache.org

下载源码包:https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.8.0/rocketmq-all-4.8.0-source-release.zip

Github:https://github.com/apache/rocketmq

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:configapache-maven-3.6.2Repositoryorgapacherocketmqrocketmq-distribution4.3.2

  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

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

[root@node-113b bin]# ./mqbroker -n localhost:9876 22:30:42.307 [main] ERROR RocketmqCommon - Failed to obtain the host name java.net.UnknownHostException: node-113b: node-113b: No address associated with hostname 	at java.net.InetAddress.getLocalHost(InetAddress.java:1505) ~[na:1.8.0_181] 	at org.apache.rocketmq.common.BrokerConfig.localHostName(BrokerConfig.java:189) [rocketmq-common-4.6 .1.jar:4.6.1]	at org.apache.rocketmq.common.BrokerConfig.<init>(BrokerConfig.java:38) [rocketmq-common-4.6.1.jar:4 .6.1]	at org.apache.rocketmq.broker.BrokerStartup.createBrokerController(BrokerStartup.java:110) [rocketmq -broker-4.6.1.jar:4.6.1]	at org.apache.rocketmq.broker.BrokerStartup.main(BrokerStartup.java:58) [rocketmq-broker-4.6.1.jar:4 .6.1]Caused by: java.net.UnknownHostException: node-113b: No address associated with hostname 	at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) ~[na:1.8.0_181] 	at java.net.InetAddress$2.lookupAllHostAddr(InetAddress.java:928) ~[na:1.8.0_181] 	at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1323) ~[na:1.8.0_181] 	at java.net.InetAddress.getLocalHost(InetAddress.java:1500) ~[na:1.8.0_181] 	... 4 common frames omitted The broker[DEFAULT_BROKER, 192.168.150.213:10911] boot success. serializeType=JSON and name server is localh ost:9876 

原因:无法解析当前的主机名

hosts里添加映射即可

192.168.150.213 node-113b
