After upgrading a server from 12.04 to 14.04 I found that the nginx web server wasn't starting automatically. I could start the server without error from the command line. Running "sudo /etc/init.d/nginx start" would produce no visible error, but the service would not be started. Running "sudo /etc/init.d/nginx restart" produces a visible "fail" error.
The nginx startup script (/etc/init.d/nginx) includes this line:
The issue is that awk returns the line that includes "spider", which creates an incorrect value for the location of the pid file, and the startup script fails. The version of /etc/init.d/nginx provided with 12.04 did not inlcude this awk command and the startup script worked without error.

The nginx startup script (/etc/init.d/nginx) includes this line:
PID=$(awk -F'[ \t;]+' '/[^#]pid/ {print $2}' /etc/nginx/ nginx.conf)
This is intended to find this line (or similar) in the nginx.conf file:
pid /var/run/nginx.pid;
My nginx.conf file includes this map directive:
map $http_user_agent $is_bot {
default 0;
~*(crawl| Google| Slurp|bingbot| tracker| click|parser| spider| msnbot| Gigabot) 1;
}
