Which nginx

The configuration file consists of directives and their parameters. Here are some examples of simple directives. The directives you can include within a server context vary depending on the traffic type. For HTTP traffic the http context , each server directive controls the processing of requests for resources at particular domains or IP addresses. One or more location contexts in a server context define how to process specific sets of URIs. In general, a child context — one contained within another context its parent — inherits the settings of directives included at the parent level.

Some directives can appear in multiple contexts, in which case you can override the setting inherited from the parent by including the directive in the child context. For changes to the configuration file to take effect, it must be reloaded. Improve this question. Daniel Li Add a comment. Active Oldest Votes. Improve this answer.

The second anwer works — Revious. If you've installed nginx via a package manager such as HomeBrew Craig Wayne Craig Wayne 3, 3 3 gold badges 30 30 silver badges 42 42 bronze badges. I just typed it on Ubuntu to make sure I hadn't lost my mind. It definitely does not show the path for which nginx "is being used". All other answers are useful but they may not help you in case nginx is not on PATH so you're getting command not found when trying to run nginx : I have nginx 1.

Once nginx is started, it can be controlled by invoking the executable with the -s parameter. Use the following syntax:. For example, to stop nginx processes with waiting for the worker processes to finish serving current requests, the following command can be executed:. Changes made in the configuration file will not be applied until the command to reload configuration is sent to nginx or it is restarted.

To reload configuration, execute:. Once the master process receives the signal to reload configuration, it checks the syntax validity of the new configuration file and tries to apply the configuration provided in it. If this is a success, the master process starts new worker processes and sends messages to old worker processes, requesting them to shut down.

Otherwise, the master process rolls back the changes and continues to work with the old configuration. Old worker processes, receiving a command to shut down, stop accepting new connections and continue to service current requests until all such requests are serviced.

After that, the old worker processes exit. A signal may also be sent to nginx processes with the help of Unix tools such as the kill utility. In this case a signal is sent directly to a process with a given process ID. The process ID of the nginx master process is written, by default, to the nginx. For getting the list of all running nginx processes, the ps utility may be used, for example, in the following way:.

A simple directive consists of the name and parameters separated by spaces and ends with a semicolon ;. If a block directive can have other directives inside braces, it is called a context examples: events , http , server , and location. Directives placed in the configuration file outside of any contexts are considered to be in the main context.

The events and http directives reside in the main context, server in http , and location in server.
