[root@localhost rocketmq]# cd store/
[root@localhost store]# mkdir commitlog
[root@localhost store]# mkdir consumequeue
[root@localhost store]# mkdir index

修改配置文件，进入2s-2m-async目录修改第一个配置文件

vim broker-a.properties
替换文件中所有内容
brokerClusterName=rocketmq-cluster
brokerName=broker-a
brockerId=0
namesrvAddr=192.168.31.21:9876//配置主机ip

将RocketMQ目录下所有xml文件内容中${user.home}替换成RocketMQ目录路径

sed -i 's#${user.home}#/root/software/rocketmq#g' *.xml

修改bin目录下runbroker.sh和runserver.sh文件

runbroker.sh

# 修改前
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
# 修改后
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn1g"

runbroker.sh

# 修改前
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
# 修改后
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

先启动namesrv（bin目录下脚本文件）

nohup sh mqnamesrv &

再启动broker（bin目录下）

nohup sh mqbroker -c /root/software/rocketmq/conf/2m-2s-async/broker-a.properties > /dev/null 2>&1 &

查看启动进程是否有启动成功

[root@localhost bin]# jps
11600 BrokerStartup
12066 Jps
