https: // emqx.io. On the EMQ X Enterprise download page, click Get FREE Trial License.
Register to log in and apply for a trial license file, then download the license file.
Replace the license file (
etc/emqx.lic) in the default certificate directory. You can also choose to change the read path of the certificate file, modify
etc/emqx.conffile, and make sure that the license file is in the updated read path and EMQ X Enterprise has read permission. Then, start EMQ X Enterprise. EMQ X Enterprise is started in the same way as EMQ X Broker, which can be seen below.
If the running EMQ X Enterprise needs to update the license file, you can use the
emqx_ctl license reload [path of the license file]command to directly update the license file without restarting EMQ X Enterprise. It should be noted that the certificate loaded by the
emqx_ctl license reloadcommand will only take effect during this run of EMQ X Enterprise. If you need to permanently update the license certificate path, you still need to replace the old certificate or modify the configuration file, which can be seen from the previous step.
