Instalación

Os usuarios da edición Plus (de pago) reciben asistencia técnica por parte do equipo de NGINX durante o proceso de instalación. Polo xeral, a instalación faise utilizando un xestor de paquetes, pois a maioría de distribucións Linux teñen o paquete nginx incluido por defecto no seu repositorio. Con todo, se o paquete non está incluído, o código fonte pódese descargar facilmente desde a páxina web oficial do proxecto. A continuación, mostrámosche como instalar e configurar NGINX nun servidor Linux:

Tamén é posible instalar a última versión acudindo aos repositorios oficiais. Primeiro hai que instalar os requirimentos previos:

# Debian
sudo apt install curl gnupg2 ca-certificates lsb-release debian-archive-keyring
# Ubuntu
sudo apt install curl gnupg2 ca-certificates lsb-release ubuntu-keyring

E despois, actualizamos a lista de respositorios:

curl https://nginx.org/keys/nginx_signing.key | gpg --dearmor | \
    sudo tee /usr/share/keyrings/nginx-archive-keyring.gpg >/dev/null
# Debian
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
    http://nginx.org/packages/debian lsb_release -cs nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list
# Ubuntu
echo "deb [signed-by=/usr/share/keyrings/nginx-archive-keyring.gpg] \
    http://nginx.org/packages/ubuntu `lsb_release -cs` nginx" \
    | sudo tee /etc/apt/sources.list.d/nginx.list

Actualizamos o repositorio:

sudo apt update

Instalamos NGINX:

sudo apt install nginx -y
