ProxySQL is a high-performance SQL proxy. ProxySQL runs as a daemon watched by a monitoring process. The process monitors the daemon and restarts it in case of a crash to minimize downtime. The daemon accepts incoming traffic from MySQL clients and forwards it to backend MySQL servers.</p> <h2 id="installing-proxysql">Installing ProxySQL</h2> <h3 id="node-configuration">Node configuration</h3> <div class="pl-table-scroll" role="region" tabindex="0" aria-label="Table 1"> <table> <thead> <tr> <th style="text-align: left">Node</th> <th style="text-align: left">Host</th> <th style="text-align: left">IP</th> </tr> </thead> <tbody> <tr> <td style="text-align: left">Node 1</td> <td style="text-align: left">db1</td> <td style="text-align: left">192.168.50.31</td> </tr> <tr> <td style="text-align: left">Node 2</td> <td style="text-align: left">db2</td> <td style="text-align: left">192.168.50.32</td> </tr> <tr> <td style="text-align: left">Node 3</td> <td style="text-align: left">db3</td> <td style="text-align: left">192.168.50.33</td> </tr> <tr> <td style="text-align: left">Node 4</td> <td style="text-align: left">proxysql</td> <td style="text-align: left">192.168.50.34</td> </tr> </tbody> </table> </div> <h3 id="prerequisites">Prerequisites</h3> <ol> <li> <p>Install CentOS 7</p>
