   Here's a helpful tip for those using #Linux or #Unix web servers. Before you hit that reload command, it's always a good idea to test your server config file for syntax errors. You can do this easily as follows:

   - For nginx: nginx -t
   - For lighttpd: lighttpd -t -f lighttpd.conf
   - For apache2: apache2 -t

   If you want to check for syntax errors on other Linux/Unix servers, I have compiled a complete list for you https://www.cyberciti.biz/tips/check-unix-linux-configuration-file-for-syntax-errors.html

     @nazokiyoubinbou yes: "sshd -T" would have saved your butt :P

     @nazokiyoubinbou Sad story: I have added that as a hook to Ansible to check SSHD config after 20 VMs lost SSH connectivity. So, if an error is found in my VM's sshd_config, it will not reboot the server and give me enough time to fix it manually.
