How can I see which flags Nginx was compiled with?

Question

How can I check what modules have been added to an nginx installation?

Another way of saying this is "how can I see which flags Nginx was compiled with?" Just wanted to add that to increase searchability.

nginx -V will list all the configured modules. There is no explicit enable/load command.

Note for noobs: If not logged in as root user, the command would be sudo nginx -V – its_me Feb 8 at 4:08

Diff-able one-liner:

2>&1 nginx -V | tr -- - '\n' | grep _module

Convenient for comparing two environments:

lsmodn="2>&1 nginx -V | tr -- - '\n' | grep _module"
diff -y <(ssh www-prd eval $lsmodn) <(ssh www-qa eval $lsmodn)

2>&1 nginx -V | tr -- - '\n' | grep _module command is totally wrong as it lists without-* options as installed! – Roman Newaza Mar 28 at 9:07
