Overview<\/h2>\n
\n
Warning:<\/div>\n
\n

We deprecated the MyDNS and NSD nameservers in cPanel & WHM version 78 and plan to remove them a future release. We strongly recommend that you migrate to PowerDNS. For more information, read our cPanel Deprecation Plan.<\/p>\n<\/p><\/div>\n<\/div>\n

MyDNS-NG (MyDNS) is DNS server software for Linux servers. MyDNS uses a database to store the server\u2019s DNS zone files, which allows it to efficiently manage large numbers (hundreds of thousands) of zone records.<\/p>\n

MyDNS requires the following minimum configuration to run on your cPanel & WHM server:<\/p>\n

    \n
  • cPanel & WHM version 11.32 or later.<\/li>\n
  • MySQL\u00ae version 5.0 or later.<\/li>\n
  • BIND<\/li>\n<\/ul>\n
    \n
    Note:<\/div>\n
    \n
      \n
    • MyDNS does not remove BIND from the system. cPanel & WHM requires the BIND service.<\/li>\n
    • MyDNS does not support Domain Name System Security Extensions (DNSSEC) or PostgreSQL\u00ae.<\/li>\n<\/ul><\/div>\n<\/div>\n

      Install MyDNS<\/h2>\n
      \n
      Note:<\/div>\n
      \n

      Currently, you cannot<\/strong> install MyDNS during the cPanel & WHM installation process.<\/p>\n<\/p><\/div>\n<\/div>\n

      To install MyDNS through the WHM interface, perform the following steps:<\/p>\n

        \n
      1. Navigate to WHM\u2019s Nameserver Selection<\/em> interface (WHM >> Home >> Service Configuration >> Nameserver Selection<\/em>).<\/li>\n
      2. Select MyDNS<\/em>.<\/li>\n
      3. Click Save<\/em>.<\/li>\n<\/ol>\n

        To install MyDNS through the command line, run the following command as the root<\/code> user:\n<\/p>\n

        \n
        \/usr\/local\/cpanel\/scripts\/setupnameserver mydns<\/code><\/pre>\n<\/div>\n
        Return to MyDNS from another DNS server<\/h2>\n
        \n
        Important:<\/div>\n
        \n
        If you change to a different DNS server and then change back to MyDNS, you must<\/strong> run a forced DNS import and restart MyDNS.<\/p>\n<\/p><\/div>\n<\/div>\n
        To perform the import and restart MyDNS, perform the following steps:<\/p>\n
          \n
        1. \n
          Run the following command as the root<\/code> user to force a DNS import:<\/p>\n
          \n
          Warning:<\/div>\n
          \n
            \n
          • This script will clear the rr<\/code> database table, which will cause DNS lookup errors until your server refreshes that table.<\/li>\n
          • You will receive a confirmation email when this command finishes. Do not<\/strong> proceed until you receive that email.<\/li>\n<\/ul><\/div>\n<\/div>\n<\/li>\n
          • \n
            Run the following command as the root user to restart MyDNS:\n<\/p>\n
            \n
            \/usr\/local\/cpanel\/scripts\/restartsrv_mydns<\/code><\/pre>\n<\/div>\n<\/li>\n<\/ol>\n
            MyDNS on your server<\/h2>\n
            The system installs MyDNS to the \/usr\/local\/cpanel\/3rdparty\/<\/code> directory. After installation, the system syncs the zone files in the \/var\/named\/<\/code> directory with the records in the MyDNS database.<\/p>\n
            Each server that uses MyDNS includes its own MySQL database for MyDNS. The server\u2019s database name corresponds to the mydns_hostname<\/code> format, where hostname<\/code> represents the server\u2019s hostname.<\/p>\n
            MyDNS on remote MySQL servers<\/h2>\n
            cPanel & WHM\u2019s implementation of MyDNS can function with a remote MySQL server.<\/p>\n
              \n
            • To set up the connection to the remote MySQL server, navigate to WHM\u2019s Manage MySQL\u00ae Profiles<\/em> interface (WHM >> Home >> SQL Services >> Manage MySQL Profiles<\/em>).<\/li>\n
            • When you run MyDNS on a dedicated MySQL server, each connected server maintains its own unique database of zone files. The MySQL server retrieves these zone files from the servers and does not retain a central copy of them.<\/li>\n<\/ul>\n
              Troubleshoot MyDNS<\/h2>\n
              Because MyDNS uses a MySQL database to store zone files, any problem with MySQL will affect MyDNS\u2019s performance. If you experience problems with MyDNS, first make certain that MySQL responds.<\/p>\n
              To confirm that MySQL responds to WHM, perform one of the following actions:<\/p>\n
                \n
              • Navigate to WHM\u2019s Show MySQL Processes<\/em> interface (WHM >> Home >> SQL Services >> Show MySQL Processes<\/em>). If MySQL responds, the system will display the SHOW PROCESSLIST<\/code> query.<\/li>\n
              • Run the following command as the root<\/code> user:\n
                \n
                netstat -tap | grep mysql<\/code><\/pre>\n<\/div>\n<\/li>\n<\/ul>\n
                If MySQL responds, the system will return information that resembles the following example:\n<\/p>\n
                \n
                tcp        0<\/span>      0<\/span> *:mysql                     :<\/em>                         LISTEN      17280<\/span>\/mysqld<\/code><\/pre>\n<\/div>\n
                To troubleshoot MyDNS further, check the following error logs:<\/p>\n
                  \n
                • \/usr\/local\/cpanel\/logs\/error_log<\/code> \u2014 The WHM error log.<\/li>\n
                • \/var\/log\/messages<\/code> \u2014 The MyDNS error log.<\/li>\n
                • \/usr\/local\/cpanel\/logs\/dnsadmin_log<\/code> \u2014 The dnsadmin<\/code> error log. WHM\u2019s dnsadmin<\/code> service interacts with DNS zone files.<\/li>\n<\/ul><\/div>\n","protected":false},"excerpt":{"rendered":"
