Hello,
First, I'm new to this Mailing List. As say my signature I'm non-English
and I'm trying the best to be understandable. If something isn't clear or
noisy, please tell me.
I'm using Nginx 1.2.1 on Debian Wheezy 64 bits, I want to host some
personals website on my dedicated server. I've installed php5-fpm, looked
at the configuration file which is /etc/php5/fpm/pool.d/www.conf and the
"listen" parameters is '/var/run/php5-fpm.sock'.
Some peoples on #nginx@freenode.org tell me I need to put 'fastcgi_pass
unix:/var/run/php5-fpm.sock;' into the virtual host configuration file
into /etc/nginx/conf.d/ directory.
I do that and then I've checked one of my website which given me a "502
Bad Gateway", it worked.
But when I'm trying to test if PHP is working with phpinfo, I've a 502 and
Wordpress doesn't works so it's clear. My configuration is messed up.
This is my configuration:
/etc/nginx/nginx.conf:
user www-data;
worker_processes 1;
error_log /var/log/nginx/error.log debug;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
}

default_type application/octet-stream;
index index.html index.php;
log_format main '$remote_addr - $remote_user [$time_local]

/etc/php5/fpm/pool.d/www.conf (unchanged):
; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by
the
; pool name ('www' here)
[www]
; Per pool prefix
; It only applies on the following directives:
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or /usr) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool
; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's
group
; will be used.
user = www-data
group = www-data
; The address on which to accept FastCGI requests.
; Valid syntaxes are:
; 'ip.add.re.ss:port' - to listen on a TCP socket to a specific
address on
; a specific port;
; 'port' - to listen on a TCP socket to all addresses on
a
; specific port;
; '/path/to/unix/socket' - to listen on a unix socket.
; Note: This value is mandatory.
listen = /var/run/php5-fpm.sock
; Set listen(2) backlog.
; Default Value: 128 (-1 on FreeBSD and OpenBSD)
;listen.backlog = 128
; Set permissions for unix socket, if one is used. In Linux, read/write
; permissions must be set in order to allow connections from a web server.
Many
; BSD-derived systems allow connections regardless of permissions.
; Default Values: user and group are set as the running user
; mode is set to 0666
;listen.owner = www-data
;listen.group = www-data
;listen.mode = 0666
; List of ipv4 addresses of FastCGI clients which are allowed to connect.
; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the
original
; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each
address
; must be separated by a comma. If this value is left blank, connections
will be
; accepted from any ip address.
; Default Value: any
;listen.allowed_clients = 127.0.0.1
; Choose how the process manager will control the number of child
processes.
; Possible Values:
; static - a fixed number (pm.max_children) of child processes;
; dynamic - the number of child processes are set dynamically based on
the
; following directives. With this process management, there
will be
; always at least 1 children.
; pm.max_children - the maximum number of children that
can
; be alive at the same time.
; pm.start_servers - the number of children created on
startup.
; pm.min_spare_servers - the minimum number of children in
'idle'
; state (waiting to process). If the
number
; of 'idle' processes is less than this
; number then some children will be
created.
; pm.max_spare_servers - the maximum number of children in
'idle'
; state (waiting to process). If the
number
; of 'idle' processes is greater than
this
; number then some children will be
killed.
; ondemand - no children are created at startup. Children will be forked
when
; new requests will connect. The following parameter are used:
; pm.max_children - the maximum number of children
that
; can be alive at the same time.
; pm.process_idle_timeout - The number of seconds after which
; an idle process will be killed.
; Note: This value is mandatory.
pm = dynamic
; The number of child processes to be created when pm is set to 'static'
and the
; maximum number of child processes when pm is set to 'dynamic' or
'ondemand'.
; This value sets the limit on the number of simultaneous requests that
will be
; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original
PHP
; CGI. The below defaults are based on a server without much resources.
Don't
; forget to tweak pm.* to fit your needs.
; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
; Note: This value is mandatory.
pm.max_children = 5
; The number of child processes created on startup.
; Note: Used only when pm is set to 'dynamic'
; Default Value: min_spare_servers + (max_spare_servers -
min_spare_servers) / 2
pm.start_servers = 2
; The desired minimum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.min_spare_servers = 1
; The desired maximum number of idle server processes.
; Note: Used only when pm is set to 'dynamic'
; Note: Mandatory when pm is set to 'dynamic'
pm.max_spare_servers = 3
; The number of seconds after which an idle process will be killed.
; 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
; recognized as a status page. It shows the following informations:
; pool - the name of the pool;
; process manager - static, dynamic or ondemand;
; start time - the date and time FPM has started;
; start since - number of seconds since FPM has started;
; accepted conn - the number of request accepted by the pool;
; listen queue - the number of request in the queue of pending
; connections (see backlog in listen(2));
; max listen queue - the maximum number of requests in the queue
; of pending connections since FPM has started;
; listen queue len - the size of the socket queue of pending
connections;
; idle processes - the number of idle processes;
; active processes - the number of active processes;
; total processes - the number of idle + active processes;
; max active processes - the maximum number of active processes since FPM
; has started;
; max children reached - number of times, the process limit has been
reached,
; when pm tries to start more children (works
only for
; pm 'dynamic' and 'ondemand');
; Value are updated in real time.
; Example output:
; pool: www
; process manager: static
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 62636
; accepted conn: 190460
; listen queue: 0
; max listen queue: 1
; listen queue len: 42
; idle processes: 4
; active processes: 11
; total processes: 15
; max active processes: 12
; max children reached: 0
;
; 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, ...);
; start time - the date and time the process has started;
; start since - the number of seconds since the process has
started;
; 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
; it's always 0 if the process is not in Idle
state
; because memory calculation is done when the
request
; processing has terminated;
; If the process is in Idle state, then informations are related to the
; last request the process has served. Otherwise informations are related
to
; the current request being served.
; Example output:
; ************************

; state: Running
; start time: 01/Jul/2011:17:53:49 +0200
; start since: 63087

;
; Note: There is a real-time FPM status monitoring sample web page
available
; It's available in: ${prefix}/share/fpm/status.html
;
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension
or it
; may conflict with a real PHP file.
; Default Value: not set
;pm.status_path = /status
; The ping URI to call the monitoring page of FPM. If this value is not
set, no
; URI will be recognized as a ping page. This could be used to test from
outside
; that FPM is alive and responding, or to
; - create a graph of FPM availability (rrd or such);
; - remove a server from a group if it is not responding (load balancing);
; - trigger alerts for the operating team (24/7).
; Note: The value must start with a leading slash (/). The value can be
; anything, but it may not be a good idea to use the .php extension
or it
; may conflict with a real PHP file.
; Default Value: not set
;ping.path = /ping
; This directive may be used to customize the response of a ping request.
The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
;ping.response = pong
; The access log file
; Default: not set
;access.log = log/$pool.access.log
; The access log format.
; The following syntax is allowed
; %%: the '%' character

; The log file for slow requests
; Default Value: not set
; Note: slowlog is mandatory if request_slowlog_timeout is set
;slowlog = log/$pool.log.slow
; The timeout for serving a single request after which a PHP backtrace
will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
; Default Value: 0
;request_slowlog_timeout = 0
; The timeout for serving a single request after which the worker process

; Possible Values: 'unlimited' or an integer greater or equal to 0
; 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 = /
; Redirect worker stdout and stderr into main error log. If not set,
stdout and
; stderr will be redirected to /dev/null according to FastCGI specs.
; Note: on highloaded environement, this can cause some delay in the page
; process time (several ms).
; Default Value: no
;catch_workers_output = yes
; 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
; exectute php code.
; Note: set an empty value to allow all extensions.
; Default Value: .php
;security.limit_extensions = .php .php3 .php4 .php5
; 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
This is the kind of log (/var/log/nginx/error.log, debug enabled) I have
when I'm trying to connect on a page which give 502, exactly the same
vhost configuration as above except for domain and document root:
