Let's take a closer look at the Etsy slash engine x slash engine x dot com file, which is engine X's
main configuration file.
The file rarely needs to be changed.
The settings for Engine X are written in the file as simple directives on a single line or as blocks
of directives on multiple lines.
The blocks are made up of a directive, open brackets, more directives and a closing bracket.
Here user w w w data specifies the user under which engine x should run.
This is usually the user named w w w data in a debian based system.
Worker underscore processes auto sets the number of worker processes to be spawned.
The keyword auto means that engine X will automatically determine the number of worker processes to
run based on the number of available CPU cores.
PID slash run slash engine x PID sets the location of the engine X process ID file.
The file is used to store the process idea of the engine x master process and can be used to send signals
to the engine X process.
Include slash tk slash engine x slash modules enabled slash dot com is an include directive that loads
configuration files from the specified directory.
The wildcard character means that all the configuration files with the conf extension in the slash tk
slash engine x slash module's enabled slash directory will be included.
This events code block provided is a configuration section in engine X's main configuration file usually
located at slash TK slash engine x slash engine x conf.
The events block specifies the settings that control how Engine X handles connection requests and manages
worker processes.
The worker underscore connection settings sets the maximum number of simultaneous connections that each
worker process can handle.
The default value is usually set to 512.
In this case, the value is set to 768.
The line hashtag multi underscore exception is commented out, meaning it won't have any effect.
The multi underscore accept setting determines whether a worker process should handle multiple connections
at once.
If multi underscore accept is set on worker processes will accept new connections as quickly as possible.
Improving performance is set to off worker processes will accept new connections one at a time.
The HTTP code block of a configuration file for the Engine X web server.
It sets various options for engine excess behavior such as file transfer, send file, TCP underscore.
No push mime type handling types underscore hash underscore max underscore size include slash TK slash
engine x slash mime types default underscore type SSL slash TLS handling SSL underscore protocols,
SSL underscore prefer underscore server underscore ciphers, logging access underscore log error, underscore
log GZIP compression g zip on and virtual host configurations include slash Etsy slash engine x, slash,
conf, slash conf include slash, Etsy slash engine x slash sites enabled slash.
Some options are commented out prefixed by hashtag and are not currently in effect.
There are different ways of adding more configurations to engine x.
One way is to put a file with the extension dot com from the conf directory and the other is to put
configurations in the site's enabled directory.
The site's enabled directory has a wildcard for all files, while the conf directory has a wildcard
for files that end in dot com.
