Set Bitnami Wordpress Application to Start on Boot on Ubuntu 20.04

To set a bitnami wordpress application to start on boot, you just need to make sure that systemctl can use the ctlscript. To do that:

1. Locate the installation directory of your bitnami wordpress. If you are following the default setting, the location should be in /opt

2. Locate the ctlscript.sh file, which is the script to start, stop and restart bitnami-application.

$ sudo find / -iname "ctlscript.sh" -type f

/opt/bitnami-wordpress-5.6-0/ctlscript.sh

3. Copy the script to /etc/init.d, and rename it to bitnami-wordpress

$ sudo cp /opt/bitnami-wordpress-5.6-0/ctlscript.sh /etc/init.t/bitnami-wordpress

4. Edit the script, and add "INIT INFO" settings below #!/bin/sh to ensure systemd can understand the script

#!/bin/sh

### BEGIN INIT INFO

# Provides:          bitnami-wordpress

# Required-Start:    $remote_fs $syslog

# Required-Stop:     $remote_fs $syslog

# Default-Start:     2 3 4 5

# Default-Stop:      0 1 6

# Short-Description: Start daemon at boot time

# Description:       Enable services provided by daemon.

### END INIT INFO

...

5. Save the file, and make systemd aware of the new startup script

$ sudo systemctl daemon-reload

6. Test the new bitnami-wordpress script

$ sudo systemctl status bitnami-wordpress

7. Enable bitnami-wordpress on boot

$ sudo systemctl enable bitnami-wordpress

8. Test it out by rebooting your machine...

$ sudo reboot

9. ...and check the status of the bitnami-wordpress service after reboot

$ sudo systemctl status bitnami-wordpress
