In the 5.0 version, the Proxy and Broker can be divided into Local mode and Cluster mode according to actual requirements. Generally, if there are no special requirements or if you follow the approach of smoothly upgrading from earlier versions, you can use Local mode.</p><ul><li>In Local mode, the Broker and Proxy are deployed in the same process, and you can run it by simply adding a Proxy configuration based on the original Broker configuration.</li><li>In Cluster mode, the Broker and Proxy are deployed separately, that is, in addition to the existing cluster, you can deploy the Proxy separately.</li></ul><h2 class="anchor anchorWithStickyNavbar_LWe7" id="deployment-in-local-mode">Deployment in Local Mode<a href="#deployment-in-local-mode" class="hash-link" aria-label="Direct link to heading" title="Direct link to heading"></a></h2><p>Since the Proxy and Broker are deployed in the same process in Local mode, the Proxy is stateless, so the main cluster configuration can still be based on the Broker.</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="start-nameserver">Start NameServer<a href="#start-nameserver" class="hash-link" aria-label="Direct link to heading" title="Direct link to heading"></a></h3><div class="language-bash codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#393A34;--prism-background-color:#f6f8fa"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-bash codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#393A34"><span class="token comment" style="color:#999988;font-style:italic">### Start Name Server first</span><span class="token plain"></span><br></span><span class="token-line" style="color:#393A34"><span class="token plain">$ </span><span class="token function" style="color:#d73a49">nohup</span><span class="token plain"> </span><span class="token function" style="color:#d73a49">sh</span><span class="token plain"> mqnamesrv </span><span class="token operator" style="color:#393A34">&</span><span class="token plain"></span><br></span><span class="token-line" style="color:#393A34"><span class="token plain"> </span><br></span><span class="token-line" style="color:#393A34"><span class="token plain"></span><span class="token comment" style="color:#999988;font-style:italic">### Verify that the Name Server has started successfully.</span><span class="token plain"></span><br></span><span class="token-line" style="color:#393A34"><span class="token plain">$ </span><span class="token function" style="color:#d73a49">tail</span><span class="token plain"> -f ~/logs/rocketmqlogs/namesrv.log</span><br></span><span class="token-line" style="color:#393A34"><span class="token plain">The Name Server boot success</span><span class="token punctuation" style="color:#393A34">..</span><span class="token plain">.</span><br></span></code></pre><div class="buttonGroup__atx"><button type="button" aria-label="Copy code to clipboard" title="Copy" class="clean-btn"><span class="copyButtonIcons_eSgA" aria-hidden="true"><svg viewBox="0 0 24 24" class="copyButtonIcon_y97N"><path fill="currentColor" d="M19,21H8V7H19M19,5H8A2,2 0 0,0 6,7V21A2,2 0 0,0 8,23H19A2,2 0 0,0 21,21V7A2,2 0 0,0 19,5M16,1H4A2,2 0 0,0 2,3V17H4V3H16V1Z"></path></svg><svg viewBox="0 0 24 24" class="copyButtonSuccessIcon_LjdS"><path fill="currentColor" d="M21,7L9,19L3.5,13.5L4.91,12.09L9,16.17L19.59,5.59L21,7Z"></path></svg></span></button></div></div></div><h3 class="anchor anchorWithStickyNavbar_LWe7" id="start-brokerproxy">Start Broker+Proxy<a href="#start-brokerproxy" class="hash-link" aria-label="Direct link to heading" title="Direct link to heading"></a></h3><h4 class="anchor anchorWithStickyNavbar_LWe7" id="single-node-single-replica-mode">Single Node Single Replica Mode<a href="#single-node-single-replica-mode" class="hash-link" aria-label="Direct link to heading" title="Direct link to heading"></a></h4><div class="theme-admonition theme-admonition-caution alert alert--warning admonition_LlT9"><div class="admonitionHeading_tbUL"><span class="admonitionIcon_kALy"><svg viewBox="0 0 16 16"><path fill-rule="evenodd" d="M8.893 1.5c-.183-.31-.52-.5-.887-.5s-.703.19-.886.5L.138 13.499a.98.98 0 0 0 0 1.001c.193.31.53.501.886.501h13.964c.367 0 .704-.19.877-.5a1.03 1.03 0 0 0 .01-1.002L8.893 1.5zm.133 11.497H6.987v-2.003h2.039v2.003zm0-3.004H6.987V5.987h2.039v4.006z"></path></svg></span>caution</div><div class="admonitionContent_S0QG"><p>This method carries a high risk, as there is only one node for the Broker, and if the Broker restarts or goes down, the entire service will be unavailable.

configured with one Slave, and there are multiple Master-Slave pairs. HA uses synchronous dual write, which only returns success to the application if both the primary and the standby have written successfully. The advantages and disadvantages of this mode are as follows:</p><ul><li>Advantages: Both data and service are free from single point failures. In the event of a Master crash, there is no delay in messages, and both the availability of the service and the availability of the data are very high.</li><li>Disadvantages: Performance is slightly lower than in the asynchronous replication mode (about 10% lower), RT for sending a single message is slightly higher, and in the current version, the standby cannot automatically switch to the primary after the primary node goes down.</li></ul><div class="language-bash codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#393A34;--prism-background-color:#f6f8fa"><div
