Step-by-Step Guide to Building and Deploying Nginx from Source on Linux

First, change to the

/opt

directory and download the Nginx 1.18.0 source archive:

<code>cd /opt
wget http://nginx.org/download/nginx-1.18.0.tar.gz</code>

Extract the archive:

<code>tar xf nginx-1.18.0.tar.gz</code>

Create the installation directory and compile Nginx:

<code>cd nginx-1.18.0
./configure --prefix=/apps/nginx
make && make install</code>

After compilation, create a symbolic link to the binary if needed and copy any additional configuration files.

Next, create a systemd service unit file (e.g.,

/etc/systemd/system/nginx.service

) with the following content:

<code>[Unit]
Description=The nginx HTTP and reverse proxy server

[Service]
PIDFile=/apps/nginx/logs/nginx.pid
ExecStart=/apps/nginx/sbin/nginx
ExecStop=/usr/bin/kill -s TERM $MAINPID
ExecReload=/apps/nginx/sbin/nginx -s reload

[Install]
WantedBy=multi-user.target</code>

Reload systemd to recognize the new unit, then start and enable Nginx:

<code>systemctl daemon-reload
systemctl start nginx
systemctl enable nginx
systemctl status nginx</code>

These commands verify that Nginx is running correctly and will start automatically on boot.
