Wordpress site with http error 500

donaldpooh · August 22, 2020, 3:53am

Goal: Configure a VPS for my own wordpress hosting.

1. Caddy version (`caddy version`):

v2.1.1 h1:X9k1+ehZPYYrSqBvf/ocUgdLSRIuiNiMo7CvyGUQKeA=

2. How I run Caddy:

configured systemd service

a. System environment:

openSUSE Leap 15.2 server with systemd.

The system has also php7, php-fpm, mariadb, wordpress installed, configured and running. Side note: I’m an intermediate linux user but a complete newbie on web server knowledge, so I read many online instructions to configure these services. All of their status show that they are actively running.

b. Command:

/usr/bin/caddy

c. Service/unit/compose file:

systemd service file:

[Unit]
Description=Caddy
Documentation=https://caddyserver.com/docs/
After=network.target

[Service]
User=caddy
Group=caddy
ExecStart=/usr/bin/caddy run --environ --config /etc/caddy/Caddyfile
ExecReload=/usr/bin/caddy reload --config /etc/caddy/Caddyfile
TimeoutStopSec=5s
LimitNOFILE=1048576
LimitNPROC=512
PrivateTmp=true
ProtectSystem=full
AmbientCapabilities=CAP_NET_BIND_SERVICE

[Install]
WantedBy=multi-user.target

d. My complete Caddyfile or JSON config:

mydomain.com:443 {
        root * /srv/www/wordpress
        php_fastcgi unix:/var/run/php-fpm.sock
        file_server
        log {
                output file /var/log/caddy/wordp.log
        }
}

3. The problem I’m having:

I’m setting the VPS as my wordpress blog page.
wordpress was installed via opensuse’s webserver repo, to the directory /srv/www/wordpress. I edited /etc/wordpress/wp-config.php to use the mariadb database I created.
For php, I edited /etc/php7/fpm/php-fpm.d/www.conf to listen to 127.0.0.1:9000 and the user:owner to caddy:caddy.

Results: When I visit my domain name in my browser, it shows an “HTTP ERROR 500” page.

4. Error messages and/or full log output:

I do not know how to format these logs from the linux command “tail …/caddylog”

5. What I already tried:

Changed many times how the caddyfile looks.There was a time when I visited the domain name, it started to download a file “setup-config.php”, in which the content started with:

* Retrieves and creates the wp-config.php file.
 *
 * The permissions for the base directory must allow for writing files in order
 * for the wp-config.php to be created using this page.
 *
 * @package WordPress
 * @subpackage Administration
 */

/**
 * We are installing.
 */
....

But now it’s just “HTTP ERROR 500”

Read too many instructions to list here.

In Caddy v2, for unix sockets, the syntax is unix/<path>. See the examples:

donaldpooh · August 22, 2020, 5:21am

Hello, thank you for the help.

I changed it to unix//var/run/php-fpm.sock

Now the http error code just becomes 502.

francislavoie · August 22, 2020, 5:57am

That would be because Caddy is unable to connect to php-fpm. Make sure it’s correctly running and that Caddy has permissions to the socket file.

Here’s the php-fpm config file:

; Start a new pool named 'www'.
; the variable $pool can be used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:

; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none

; Choose how the process manager will control the number of child processes.
; Possible Values:
;   static  - a fixed number (pm.max_children) of child processes;

; Note: Used only when pm is set to 'ondemand'
; Default Value: 10s
;pm.process_idle_timeout = 10s;

; The number of requests each child process should execute before respawning.
; This can be useful to work around memory leaks in 3rd party libraries. For
; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
; Default Value: 0
;pm.max_requests = 500

; The URI to view the FPM status page. If this value is not set, no URI will be

; By default the status page output is formatted as text/plain. Passing either
; 'html', 'xml' or 'json' in the query string will return the corresponding
; output syntax. Example:
;   http://www.foo.bar/status
;   http://www.foo.bar/status?json
;   http://www.foo.bar/status?html
;   http://www.foo.bar/status?xml
;
; By default the status page only outputs short status. Passing 'full' in the
; query string will also return status for each pool process.
; Example:
;   http://www.foo.bar/status?full
;   http://www.foo.bar/status?json&full
;   http://www.foo.bar/status?html&full
;   http://www.foo.bar/status?xml&full
; The Full status returns for each process:
;   pid                  - the PID of the process;
;   state                - the state of the process (Idle, Running, ...);

;   requests             - the number of requests the process has served;
;   request duration     - the duration in µs of the requests;
;   request method       - the request method (GET, POST, ...);
;   request URI          - the request URI with the query string;
;   content length       - the content length of the request (only with POST);
;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
;   script               - the main script called (or '-' if not set);
;   last request cpu     - the %cpu the last request consumed
;                          it's always 0 if the process is not in Idle state
;                          because CPU calculation is done when the request
;                          processing has terminated;
;   last request memory  - the max amount of memory the last request consumed

;                          because memory calculation is done when the request
;                          processing has terminated;
; If the process is in Idle state, then informations are related to the

; Default Value: 0
;request_slowlog_timeout = 0

; Depth of slow log stack trace.
; Default Value: 20

; The timeout for serving a single request after which the worker process will
; be killed. This option should be used when the 'max_execution_time' ini option

; Default Value: system defined value
;rlimit_core = 0

; Chroot to this directory at the start. This value must be defined as an
; absolute path. When this value is not set, chroot is not used.
; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
; of its subdirectories. If the pool prefix is not set, the global prefix
; will be used instead.
; Note: chrooting is a great security feature and should be used whenever
;       possible. However, all PHP paths will be relative to the chroot
;       (error_log, sessions.save_path, ...).
; Default Value: not set
;chroot =

; Chdir to this directory at the start.
; Note: relative path can be used.
; Default Value: current directory or / when chroot
;chdir = /var/www

; Redirect worker stdout and stderr into main error log. If not set, stdout and

; process time (several ms).
; Default Value: no
;catch_workers_output = yes

; Decorate worker output with prefix and suffix containing information about
; the child that writes to the log and if stdout or stderr is used as well as
; log level and time. This options is used only if catch_workers_output is yes.
; Settings to "no" will output data as written to the stdout or stderr.
; Default value: yes
;decorate_workers_output = no

; Clear environment in FPM workers
; Prevents arbitrary environment variables from reaching FPM worker processes
; by clearing the environment in workers before env vars specified in this
; pool configuration are added.
; Setting to "no" will make all environment variables available to PHP code
; via getenv(), $_ENV and $_SERVER.
; Default Value: yes
;clear_env = no

; Limits the extensions of the main script FPM will allow to parse. This can
; prevent configuration mistakes on the web server side. You should only limit
; FPM to .php extensions to prevent malicious users to use other extensions to
; execute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5 .php7

; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
; the current environment.
; Default Value: clean env
;env[HOSTNAME] = $HOSTNAME
;env[PATH] = /usr/local/bin:/usr/bin:/bin
;env[TMP] = /tmp
;env[TMPDIR] = /tmp
;env[TEMP] = /tmp

; Additional php.ini defines, specific to this pool of workers. These settings
; overwrite the values previously defined in the php.ini. The directives are the
; same as the PHP SAPI:
;   php_value/php_flag             - you can set classic ini defines which can
;                                    be overwritten from PHP call 'ini_set'.
;   php_admin_value/php_admin_flag - these directives won't be overwritten by
;                                     PHP call 'ini_set'
; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.

; Defining 'extension' will load the corresponding shared extension from
; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
; overwrite previously defined php.ini values, but will append the new value
; instead.

; Note: path INI options can be relative and will be expanded with the prefix
; (pool, global or /usr)

; Default Value: nothing is defined by default except the values in php.ini and
;                specified at startup with the -d argument
;php_admin_value[sendmail_path] = /usr/sbin/sendmail -t -i -f www@my.domain.com
;php_flag[display_errors] = off
;php_admin_value[error_log] = /var/log/fpm-php.www.log
;php_admin_flag[log_errors] = on
;php_admin_value[memory_limit] = 32M

Can you check if it is correct? I remember I only changed user/group, listen.owner/group/mode. Should I change the pool name “www”?

This means it uses a TCP socket rather than a unix socket. Change your config to use 127.0.0.1:9000 instead of the unix socket.

Also make sure the service is running!

Thank you very much for the help. I finally see the wordpress page. You helped me to accomplish an otherwise impossible task. There could be so many things I need to understand to get through…
