Почему «welcome to nginx» вместо «страницы с php» (Ubuntu)?

Question

[anon123565]

/etc/nginx/sites_available/default

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

        root /var/www/html;

        index index.php index.html;

        server_name _;

        location / {
                try_files $uri $uri/ =404;
        }

        location ~ \.php$ {
                include snippets/fastcgi-php.conf;
                fastcgi_pass unix:/var/run/php/php8.0-fpm.sock;
        }
}

/etc/nginx/nginx.conf

ser www-data;
worker_processes 4;
pid /run/nginx.pid;

events {
        worker_connections 768;
}

http {

        sendfile on;
        tcp_nopush on;
        tcp_nodelay on;
        keepalive_timeout 65;
        types_hash_max_size 2048;

        include /etc/nginx/mime.types;
        default_type application/octet-stream;

        access_log /var/log/nginx/access.log;
        error_log /var/log/nginx/error.log;

        gzip on;
        gzip_disable "msie6";

        include /etc/nginx/conf.d/*.conf;
        include /etc/nginx/sites-enabled/*;
}

должна открываться эта страница в localhost:
/var/www/html/index.php

<?php
    phpinfo();
?>

а открывается страница с "welcome to nginx"

В sites-enabled есть симлинк-то на конфиг?

[Дмитрий]

Что в файле /etc/php/8.0/fpm/php-fpm.conf
Там ищите
listen = /run/php/8.0-fpm.sock
либо
listen = 127.0.0.1:9000
Нужное закоментировать добавив ;

3.ы
делаем резервные копии файлов которые будем редактировать (позже, тонкая настройка)
sudo cp /etc/nginx/nginx.conf /etc/nginx/nginx.conf.def
добавляем хост localhost
sudo cp /etc/nginx/sites-available/default /etc/nginx/sites-available/localhost
удаляем симлинк на дефолтную конфигурацию
sudo rm /etc/nginx/sites-enabled/default
активируем наш новый хост
sudo ln -nfs /etc/nginx/sites-available/localhost /etc/nginx/sites-enabled/
Потом в файле localhost надо поменять
server_name localhost;

listen = /run/php/8.0-fpm.sock

Дмитрий, у меня там такого нету вообще...

[Дмитрий]

anon123565, а вы php-fpm установили?
sudo apt install php-fpm
У вас точно 8.0 ?

[anon123565]

Дмитрий, да, вот все стоит:

/var/run/php# ls
php8.0-fpm.pid php8.0-fpm.sock php-fpm.sock

[Дмитрий]

anon123565, значит вы не внимательно просмотрели файл. Там обязательно будет listen

[Дмитрий]

anon123565, копайте nginx, после правки конфигов проверяйте
sudo service nginx configtest
Если все хорошо
sudo service nginx reload

[anon123565]

Дмитрий, его там нет

[anon123565]

Дмитрий,

sudo service nginx configtest

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

и все-равно "Welcome to nginx"

[Дмитрий]

anon123565, вечером кину все файлы

[anon123565]

Дмитрий, если мне это компожет) я столько уже всего переделывала. на одном компе все работает а на этом нет

;;;;;;;;;;;;;;;;;;;;;
; FPM Configuration ;
;;;;;;;;;;;;;;;;;;;;;

; All relative paths in this configuration file are relative to PHP's install
; prefix (/usr). This prefix can be dynamically changed by using the
; '-p' argument from the command line.

;;;;;;;;;;;;;;;;;;
; Global Options ;
;;;;;;;;;;;;;;;;;;

[global]
; Pid file
; Note: the default prefix is /var
; Default Value: none
; Warning: if you change the value here, you need to modify systemd
; service PIDFile= setting to match the value here.
pid = /run/php/php8.0-fpm.pid

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; into a local file.
; Note: the default prefix is /var
; Default Value: log/php-fpm.log
error_log = /var/log/php8.0-fpm.log

; syslog_facility is used to specify what type of program is logging the
; message. This lets syslogd specify that messages from different facilities
; will be handled differently.
; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
; Default Value: daemon
;syslog.facility = daemon

; syslog_ident is prepended to every message. If you have multiple FPM
; instances running on the same server, you can change the default value
; which must suit common needs.
; Default Value: php-fpm
;syslog.ident = php-fpm

; Log level
; Possible Values: alert, error, warning, notice, debug
; Default Value: notice
;log_level = notice

; Log limit on number of characters in the single line (log entry). If the
; line is over the limit, it is wrapped on multiple lines. The limit is for
; all logged characters including message prefix and suffix if present. However
; the new line character does not count into it as it is present only when
; logging to a file descriptor. It means the new line character is not present
; when logging to syslog.
; Default Value: 1024
;log_limit = 4096

; Log buffering specifies if the log line is buffered which means that the
; line is written in a single write operation. If the value is false, then the
; data is written directly into the file descriptor. It is an experimental
; option that can potentionaly improve logging performance and memory usage
; for some heavy logging scenarios. This option is ignored if logging to syslog
; as it has to be always buffered.
; Default value: yes
;log_buffering = no

; If this number of child processes exit with SIGSEGV or SIGBUS within the time
; interval set by emergency_restart_interval then FPM will restart. A value
; of '0' means 'Off'.
; Default Value: 0
;emergency_restart_threshold = 0

; Interval of time used by emergency_restart_interval to determine when
; a graceful restart will be initiated.  This can be useful to work around
; accidental corruptions in an accelerator's shared memory.
; Available Units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;emergency_restart_interval = 0

; Time limit for child processes to wait for a reaction on signals from master.
; Available units: s(econds), m(inutes), h(ours), or d(ays)
; Default Unit: seconds
; Default Value: 0
;process_control_timeout = 0

; The maximum number of processes FPM will fork. This has been designed to control
; the global number of processes when using dynamic PM within a lot of pools.
; Use it with caution.
; Note: A value of 0 indicates no limit
; Default Value: 0
; process.max = 128

; Specify the nice(2) priority to apply to the master process (only if set)
; The value can vary from -19 (highest priority) to 20 (lowest priority)
; Note: - It will only work if the FPM master process is launched as root
;       - The pool process will inherit the master process priority
;         unless specified otherwise
; Default Value: no set
; process.priority = -19

; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
; Default Value: yes
;daemonize = yes

; Set open file descriptor rlimit for the master process.
; Default Value: system defined value
;rlimit_files = 1024

; Set max core size rlimit for the master process.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; Specify the event mechanism FPM will use. The following is available:
; - select     (any POSIX os)
; - poll       (any POSIX os)
; - epoll      (linux >= 2.5.44)
; - kqueue     (FreeBSD >= 4.1, OpenBSD >= 2.9, NetBSD >= 2.0)
; - /dev/poll  (Solaris >= 7)
; - port       (Solaris >= 10)
; Default Value: not set (auto detection)
;events.mechanism = epoll

; When FPM is built with systemd integration, specify the interval,
; in seconds, between health report notification to systemd.
; Set to 0 to disable.
; Available Units: s(econds), m(inutes), h(ours)
; Default Unit: seconds
; Default value: 10
;systemd_interval = 10

;;;;;;;;;;;;;;;;;;;;
; Pool Definitions ;
;;;;;;;;;;;;;;;;;;;;

; Multiple pools of child processes may be started with different listening
; ports and different management options.  The name of the pool will be
; used in logs and stats. There is no limitation on the number of pools which
; FPM can handle. Your system will tell you anyway :)

; Include one or more files. If glob(3) exists, it is used to include a bunch of
; files from a glob(3) pattern. This directive can be used everywhere in the
; file.
; Relative path can also be used. They will be prefixed by:
;  - the global prefix if it's been set (-p argument)
;  - /usr otherwise
