至
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128 -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
6.2修改runbroker文件：
vi runbroker.sh
修改
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
至
JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m"
7.启动nameserver
cd /usr/local/lib/rocketmq-all-4.7.1-bin-release/bin./mqnamesrv

11.消息测试
11.1配置nameserver地址：
#编辑profile文件 vi /etc/profile #设置nameserver服务器，添加如下一行export NAMESRV_ADDR=192.168.1.101:9876#刷新 source /etc/profile
11.2测试消息发送命令
sh tools.sh org.apache.rocketmq.example.quickstart.Producer
