Estou utilizando o nginx para PHP. No caso do Codeligniter, fiz os mesmo passos da video aula e das atividades e não consigo carregar as páginas depois do index.php/

Acredito que seja um problema com o nginx. Testei com este tutorial http://localhost/codelgniter/user_guide/general/controllers.html#let-s-try-it-hello-world do próprio website do codeligniter e ocorre o mesmo problema.

Acesso a URL http://localhost/codelgniter/index.php/blog/ Aparece o erro > 404 Not Found nginx/1.14.0 (Ubuntu)

Meu nginx default está assim:

Default server configuration

# server { listen 80 default_server; listen [::]:80 default_server;

# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332
#
# Read up on ssl_ciphers to ensure a secure configuration.
# See: https://bugs.debian.org/765782
#
# Self signed certs generated by the ssl-cert package
# Don't use them in a production server!
#
# include snippets/snakeoil.conf;

root /var/www;

# Add index.php to the list if you are using PHP
index index.php index.html index.htm index.nginx-debian.html;

server_name _;

location / {
    # First attempt to serve request as file, then
    # as directory, then fall back to displaying a 404.
    try_files $uri $uri/ /index.php;
            #try_files $uri $uri/ =404;
}

# pass PHP scripts to FastCGI server
#
location ~ \.php$ {
    include snippets/fastcgi-php.conf;
#
#    # With php-fpm (or other unix sockets):
    fastcgi_pass unix:/var/run/php/php7.2-fpm.sock;
#    # With php-cgi (or other tcp sockets):
#    fastcgi_pass 127.0.0.1:9000;
}

# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
location ~ /\.ht {
    deny all;
}

}
