Hi,

You can try the following method for restarting the Webuzo service on reboot:
1. Rename the /etc/init.d/webuzo file on your server using the following command as root:
mv /etc/init.d/webuzo /etc/init.d/webuzo_bak

2. Edit the following file existing on your server:
/etc/systemd/system/webuzo.service

3. Replace the following in the opened file:
ExecStart=/etc/init.d/webuzo start
ExecStop=/etc/init.d/webuzo stop
ExecReload=/etc/init.d/webuzo restart

with:

ExecStart=/usr/local/webuzo/conf/webuzo/emps/emps start
ExecStop=/usr/local/webuzo/conf/webuzo/emps/emps stop
ExecReload=/usr/local/webuzo/conf/webuzo/emps/emps restart

4. Once done, save the file and then execute the following command as root:
systemctl enable webuzo

For restarting Nginx on Reboot you can try the following solution:
sudo systemctl unmask nginx.service
sudo systemctl enable nginx
