+title: "Four Methods to Feed Name Server Address List"
+categories:
+ - RocketMQ
+tags:
+ - RocketMQ
+ - Name Server
+---
+
+Apache RocketMQ is a distributed system that each components should be properly coordinated to work smoothly. Name
+servers are designed to take much of this responsibility through managing topic route information.
+
+The management, roughly speaking, consists two parts. The first one is that brokers report to name servers on meta data
+of themselves and topics they have. The second is serving clients, including producer, consumer and command line
+ executables these meta data.
+
+As a result, before launching brokers and clients, we need to feed name server address list to them. Apache RocketMQ
+provides four methods to achieve this goal.
+
+1. Programmatic Way
+
+ For broker, we may specify `namesrvAddr=name-server-ip1:port;name-server-ip2:port` in broker configuration file.
+ Alternatively, we may pass a parameter like `-n name-server-ip1:port;name-server-ip2:port` to `mqbroker` script.
+
+ For producers and consumers, we may feed name server address list to them as follows:
+
+ `
+ DefaultMQProducer producer = new DefaultMQProducer("please_rename_unique_group_name");
+ producer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");`
+
+ `
+ DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("please_rename_unique_group_name");
+ consumer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");`
+
+ If you use admin command line from shell, you may specify this way:
+ `sh mqadmin command-name -n name-server-ip1:port;name-server-ip2:port -x other-options`
+
+ a simple example is:
+ `sh mqadmin -n localhost:9876 clusterList`
+ assuming to query cluster info on the name server node.
+
+ If integrating admin tool into your own dashboard, you may
+ `DefaultMQAdminExt defaultMQAdminExt = new DefaultMQAdminExt("please_rename_unique_group_name");
+ defaultMQAdminExt.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");`
+
+
+2. Environment Variable
+
+ You can export `NAMESRV_ADDR` environment variable. Brokers and clients will examine and use its value if set.
+
+
+3. Java Options
+
+ Similar to environment variable, you may specify the sequel java option `rocketmq.namesrv.addr` before launching your
+ application.
+
+4. HTTP endpoint
+
+ If you do not specify name server address list using previously mentioned methods, Apache RocketMQ will periodically
+ access the following HTTP end point to acquire and update name server address list.
+
+ On default, the end point is:
+
+ `http://jmenv.tbsite.net:8080/rocketmq/nsaddr`
+
+ You may override `jmenv.tbsite.net` by this java option: `rocketmq.namesrv.domain`,
+ You may also override `nsaddr` part by this java option: `rocketmq.namesrv.domain.subgroup`
+
+ This method is recommended because it gives you maximum flexibility, aka, you can dynamically add or
+ remove name server node without necessity of rebooting your brokers and clients according to your name servers'
+ system load.

<meta itemprop="description" content="The following questions are frequently asked with regard to the RocketMQ project in general. If you have further questions, make sure to consult the documentation or ask the community.General1. Why create rocketmq project instead of selecting other products?In some cases, slower consumers can slow down the producers. We tried our best efforts to handle this problems through throttling, circuit breaker or degradation, but it cannot scale out gracefully. So we begin to focus on the popular messaging solution Kafka at that time. Unfortunately, Kafka can not meet our requirements such as low latency and high reliability. So we decided to innovate a new messaging middleware to handle a broad set of use cases, ranging from traditional publish/subscribe scenario to demandingly high volume realtime transaction system that tolerates no message loss.">

+and fulfill much of this responsibility through managing topic route information.</p>
+
+<p>The management, roughly speaking, consists two parts:</p>
+<ul>
+ <li>Brokers periodically renew meta data, including topics they have, which are kept in every name servers.</li>
+ <li>Name servers are serving clients, including producers, consumers and command line clients with the latest routing information.</li>
+</ul>
+
+<p>Therefore, before launching brokers and clients, we need to tell them how to reach name servers by feeding them with a name server address list.
+In Apache RocketMQ, this can be done in four ways.</p>
+
+<ol>
+ <li>
+ <p>Programmatic Way</p>
+
+ <p>For broker, we may specify <code class="highlighter-rouge">namesrvAddr=name-server-ip1:port;name-server-ip2:port</code> in broker configuration file.</p>
+
+ <p>For producers and consumers, we may feed name server address list to them as follows:</p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQProducer producer = new DefaultMQProducer("please_rename_unique_group_name");
+producer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("please_rename_unique_group_name");
+consumer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p>If you use admin command line from shell, you may specify this way:
+<code class="highlighter-rouge">sh mqadmin command-name -n name-server-ip1:port;name-server-ip2:port -X OTHER-OPTION</code></p>
+
+ <p>a simple example is:
+<code class="highlighter-rouge">sh mqadmin -n localhost:9876 clusterList</code>
+assuming to query cluster info on the name server node.</p>
+
+ <p>If integrating admin tool into your own dashboard, you may
+<code class="highlighter-rouge">DefaultMQAdminExt defaultMQAdminExt = new DefaultMQAdminExt("please_rename_unique_group_name");
+ defaultMQAdminExt.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+ </li>
+ <li>
+ <p>Java Options</p>
+
+ <p>Name server address list may also be fed to your application through specifying the sequel java option
+ <code class="highlighter-rouge">rocketmq.namesrv.addr</code> before launching.</p>
+ </li>
+ <li>
+ <p>Environment Variable</p>
+
+ <p>You can export <code class="highlighter-rouge">NAMESRV_ADDR</code> environment variable. Brokers and clients will examine and use its value if set.</p>
+ </li>
+ <li>
+ <p>HTTP Endpoint</p>
+
+ <p>If you do not specify name server address list using previously mentioned methods, Apache RocketMQ will access
+ the following HTTP end point to acquire and update name server address list every two minutes with initial delay of
+ ten seconds.</p>
+
+ <p>On default, the end point is:</p>
+
+ <p><code class="highlighter-rouge">http://jmenv.tbsite.net:8080/rocketmq/nsaddr</code></p>
+
+ <p>You may override <code class="highlighter-rouge">jmenv.tbsite.net</code> by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain</code>,
+ You may also override <code class="highlighter-rouge">nsaddr</code> part by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain.subgroup</code></p>
+
+ <p>If you are running Apache RocketMQ in production, this method is recommended because it gives you maximum flexibility
+ \u2013 you can dynamically add or remove name server nodes without necessity of rebooting your brokers and clients
+ according to your name servers\u2019 system load.</p>
+ </li>
+</ol>
+
+<ul>
+ <li>
+ <p>Priority</p>
+
+ <p>Methods introduced first take precedence over the latter, namely, <br />
+ <code class="highlighter-rouge">Programmatic Way &gt; Java Options &gt; Environment Variable &gt; HTTP Endpoint</code></p>

+ <p>In Apache RocketMQ, name servers are designed to coordinate each component of the distributed system
+and fulfill much of this responsibility through managing topic route information.</p>
+
+<p>The management, roughly speaking, consists two parts:</p>
+<ul>
+ <li>Brokers periodically renew meta data, including topics they have, which are kept in every name servers.</li>
+ <li>Name servers are serving clients, including producers, consumers and command line clients with the latest routing information.</li>
+</ul>
+
+<p>Therefore, before launching brokers and clients, we need to tell them how to reach name servers by feeding them with a name server address list.
+In Apache RocketMQ, this can be done in four ways.</p>
+
+<ol>
+ <li>
+ <p>Programmatic Way</p>
+
+ <p>For broker, we may specify <code class="highlighter-rouge">namesrvAddr=name-server-ip1:port;name-server-ip2:port</code> in broker configuration file.</p>
+
+ <p>For producers and consumers, we may feed name server address list to them as follows:</p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQProducer producer = new DefaultMQProducer("please_rename_unique_group_name");
+producer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p><code class="highlighter-rouge">
+DefaultMQPushConsumer consumer = new DefaultMQPushConsumer("please_rename_unique_group_name");
+consumer.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+
+ <p>If you use admin command line from shell, you may specify this way:
+<code class="highlighter-rouge">sh mqadmin command-name -n name-server-ip1:port;name-server-ip2:port -X OTHER-OPTION</code></p>
+
+ <p>a simple example is:
+<code class="highlighter-rouge">sh mqadmin -n localhost:9876 clusterList</code>
+assuming to query cluster info on the name server node.</p>
+
+ <p>If integrating admin tool into your own dashboard, you may
+<code class="highlighter-rouge">DefaultMQAdminExt defaultMQAdminExt = new DefaultMQAdminExt("please_rename_unique_group_name");
+ defaultMQAdminExt.setNamesrvAddr("name-server1-ip:port;name-server2-ip:port");</code></p>
+ </li>
+ <li>
+ <p>Java Options</p>
+
+ <p>Name server address list may also be fed to your application through specifying the sequel java option
+ <code class="highlighter-rouge">rocketmq.namesrv.addr</code> before launching.</p>
+ </li>
+ <li>
+ <p>Environment Variable</p>
+
+ <p>You can export <code class="highlighter-rouge">NAMESRV_ADDR</code> environment variable. Brokers and clients will examine and use its value if set.</p>
+ </li>
+ <li>
+ <p>HTTP Endpoint</p>
+
+ <p>If you do not specify name server address list using previously mentioned methods, Apache RocketMQ will access
+ the following HTTP end point to acquire and update name server address list every two minutes with initial delay of
+ ten seconds.</p>
+
+ <p>On default, the end point is:</p>
+
+ <p><code class="highlighter-rouge">http://jmenv.tbsite.net:8080/rocketmq/nsaddr</code></p>
+
+ <p>You may override <code class="highlighter-rouge">jmenv.tbsite.net</code> by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain</code>,
+ You may also override <code class="highlighter-rouge">nsaddr</code> part by this java option: <code class="highlighter-rouge">rocketmq.namesrv.domain.subgroup</code></p>
+
+ <p>If you are running Apache RocketMQ in production, this method is recommended because it gives you maximum flexibility
+ \u2013 you can dynamically add or remove name server nodes without necessity of rebooting your brokers and clients
+ according to your name servers\u2019 system load.</p>
+ </li>
+</ol>
+
+<ul>
+ <li>
+ <p>Priority</p>
+
+ <p>Methods introduced first take precedence over the latter, namely, <br />
+ <code class="highlighter-rouge">Programmatic Way > Java Options > Environment Variable > HTTP Endpoint</code></p>
+ </li>
+</ul>
