Configuration File

5 min to read

Introduction

For a Web Server, nginx's job is to run static/dynamic content. And which content of the system to run will be determined in the Configuration files.

📘

The nginx config file will have the extension .conf

Access

The nginx config file is usually located in the /etc/nginx/ directory, use the cd command to access the nginx folder.

cd /etc/nginx

Next, we use the ls command to list all files in the application.

ls -lh

Assume that the result of the file list is as follows

# drwxr-xr-x 2 root root 4.0K Apr 21  2020 conf.d
# -rw-r--r-- 1 root root 1.1K Feb  4  2019 fastcgi.conf
# -rw-r--r-- 1 root root 1007 Feb  4  2019 fastcgi_params
# -rw-r--r-- 1 root root 2.8K Feb  4  2019 koi-utf
# -rw-r--r-- 1 root root 2.2K Feb  4  2019 koi-win
# -rw-r--r-- 1 root root 3.9K Feb  4  2019 mime.types
# drwxr-xr-x 2 root root 4.0K Apr 21  2020 modules-available
# drwxr-xr-x 2 root root 4.0K Apr 17 14:42 modules-enabled
# -rw-r--r-- 1 root root 1.5K Feb  4  2019 nginx.conf
# -rw-r--r-- 1 root root  180 Feb  4  2019 proxy_params
# -rw-r--r-- 1 root root  636 Feb  4  2019 scgi_params
# drwxr-xr-x 2 root root 4.0K Apr 17 14:42 sites-available
# drwxr-xr-x 2 root root 4.0K Apr 17 14:42 sites-enabled
# drwxr-xr-x 2 root root 4.0K Apr 17 14:42 snippets
# -rw-r--r-- 1 root root  664 Feb  4  2019 uwsgi_params
# -rw-r--r-- 1 root root 3.0K Feb  4  2019 win-utf

In those files, we will find a file named nginx.conf, this is the main config file of nginx.

We will use the cat command to read this config file.

cat nginx.conf

After running the above command, we will see the following content

# user www-data;

# worker_processes auto;

# pid /run/nginx.pid;

# include /etc/nginx/modules-enabled/*.conf;


# events {

#     worker_connections 768;

#     include /etc/nginx/conf.d/*.conf;

#     include /etc/nginx/sites-enabled/*;

# }



# #mail {

# #    # See sample authentication script at:

# #    # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript

# # 

# #    # auth_http localhost/auth.php;

# #    # pop3_capabilities "TOP" "USER";

# #    # imap_capabilities "IMAP4rev1" "UIDPLUS";

# # 

# #    server {

# #        listen     localhost:110;

# #        protocol   pop3;

# #        proxy      on;

# #    }

# # 

# #    server {

# #        listen     localhost:143;

# #        protocol   imap;

# #        proxy      on;

# #    }

# #}

There seems to be a lot of information in the config and it seems difficult to understand, but don't worry, we will create a new config file and start learning.
