启动服务器
~/aliSpace/recketmq/rocketmq-all-4.2.0/distribution/target/apache-rocketmq ⌚ 15:00:25
$ nohup sh bin/mqnamesrv &查看启动日志
~/aliSpace/recketmq/rocketmq-all-4.2.0/distribution/target/apache-rocketmq ⌚ 15:00:44

Before sending/receiving messages, we need to tell clients the location of name servers. RocketMQ provides multiple ways to achieve this. For simplicity, we use environment variable NAMESRV_ADDR
译：在发送/接收消息前，我们需要告诉客户端：消息服务器的地址：端口（本地的话可以用localhost：端口）。RocketMQ提供多种方式来实现它。
1.下面我们以命令行设置NAMESRV_ADDR的方式来实现它。
注意需要进入到mq目录下：
~/aliSpace/recketmq/rocketmq-all-4.2.0/distribution/target/apache-rocketmq ⌚ 15:17:31
$ export NAMESRV_ADDR=localhost:98762.发送一条消息
~/aliSpace/recketmq/rocketmq-all-4.2.0/distribution/target/apache-rocketmq ⌚ 15:26:44
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

Send shutdown request to mqbroker(2207) OK好了，一个简单的开始就结束了
