centos8 下启动rocketmq

Start Name Server

> nohup sh bin/mqnamesrv &

> tail -f ~/logs/rocketmqlogs/namesrv.log

The Name Server boot success...

1、先启动NameServer：

   在bin下执行:  nohup sh mqnamesrv &

   查看是否启动成功:  tail -f ~/logs/rocketmqlogs/namesrv.log

Start Broker

> nohup sh bin/mqbroker -n localhost:9876 &

> tail -f ~/logs/rocketmqlogs/broker.log

The broker[%s, 172.30.30.233:10911] boot success...

 

2. 启动broker:  nohup sh mqbroker -n 服务器ip:9876 autoCreateTopicEnable=true &

 

   注:      在rocketmq   的/conf/broker.conf中添加上这段代码  brokerIP1=服务器ip

 

   验证是否启动成功:  tail -f ~/logs/rocketmqlogs/broker.log

 

 

-遇到报错------------------------------------------------------------

1. linux必须已配置  JAVA_HOME

2. 修改runbroker.sh和runserver.sh，将配置的内存调小的方法

   1) runbroker.sh

      vim /usr/local/server/mq/rocketmq/distribution/bin/runbroker.sh

      JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
 
     改为：
 
     JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m"

  2) runserver.sh

     vim /usr/local/server/mq/rocketmq/distribution/bin/runserver.sh

     JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
 
    改为：
 
    JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn125m -XX:MetaspaceSize=128m    

   -XX:MaxMetaspaceSize=320m"

3.  把本地pom.xml中的引用改为和服务器上一致的版本。
