The location of the error log file can be check by using phpinfo() function. Create a simple PHP file containing phpinfo() function and run it. It will display the information about PHP configuration.
Run the above program and search for error_log directive using f3 on chrome. This will show the location of the logfile. Following is an example run on WAMP server, but the procedures will be the same as described below for every development stack. Open your php.ini file as specified and edit following directives to specify the path of the error log file to some other location. With FPM you can run several pools of processes with different setting. These are settings that can be tweaked per pool. listen stringThe address on which to accept FastCGI requests. Valid syntaxes are: 'ip.add.re.ss:port', 'port', '/path/to/unix/socket'. This option is mandatory for each pool. listen.backlog intSet listen(2) backlog. A value of listen.allowed_clients stringList of IPv4 or IPv6 addresses of FastCGI clients which are allowed to connect. Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original PHP FastCGI (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: not set (any ip address accepted). listen.owner stringSet 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 0660. listen.group stringSee listen.mode stringSee listen.backlog 1 stringWhen POSIX Access Control Lists are supported you can set them using this option. When set, listen.backlog 4 stringSee listen.backlog 6 stringUnix user of FPM processes. This option is mandatory. listen.backlog 7 stringUnix group of FPM processes. If not set, the default user's group is used. listen.backlog 8 stringChoose how the process manager will control the number of child processes. Possible values:
-1 3 intThe number of child processes to be created when This option sets the limit on the number of simultaneous requests that will be served. Equivalent to the ApacheMaxClients directive with mpm_prefork and to the PHP_FCGI_CHILDREN environment variable in the original PHP FastCGI. -1 5 intThe number of child processes created on startup. Used only when -1 9 intThe desired minimum number of idle server processes. Used only when -1 0 intThe desired maximum number of idle server processes. Used only when 511 5 intThe number of rate to spawn child processes at once. Used only when The number of seconds after which an idle process will be killed. Used only when listen.allowed_clients 0 intThe 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. listen.allowed_clients 1 stringThe address on which to accept FastCGI status request. This creates a new invisible pool that can handle requests independently. This is useful if the main pool is busy with long running requests because it is still possible to get the FPM status page before finishing the long running requests. The syntax is the same as for directive. Default value: none. listen.allowed_clients 2 stringThe URI to view the FPM status page. This value must start with a leading slash (/). If this value is not set, no URI will be recognized as a status page. Default value: none. listen.allowed_clients 3 stringThe 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. Please note that the value must start with a leading slash (/). listen.allowed_clients 4 stringThis directive may be used to customize the response to a ping request. The response is formatted as text/plain with a 200 response code. Default value: pong. listen.allowed_clients 5 intSpecify the nice(2) priority to apply to the worker process (only if set). The value can vary from -19 (highest priority) to 20 (lower priority). Default value: not set. listen.allowed_clients 6 boolSet the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user or group is different than the master process user. It allows to create process core dump and ptrace the process for the pool user. Default Value: no. Since PHP 7.0.29, 7.1.17 and 7.2.5. listen.allowed_clients 7 stringSpecify prefix for path evaluation 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 does not stop script execution for some reason. A value of '0' means 'Off'. Available units: s(econds)(default), m(inutes), h(ours), or d(ays). Default value: 0. The timeout set by is not engaged after a fastcgi_finish_request or when application has finished and internal shutdown functions are being called. This directive will enable timeout limit to be applied unconditionally even in such cases. Default value: no. Since PHP 7.3.0. The timeout for serving a single request after which a PHP backtrace will be dumped to the 'slowlog' file. A value of '0' means 'Off'. Available units: s(econds)(default), m(inutes), h(ours), or d(ays). Default value: 0. listen.allowed_clients 8 intThe depth of slowlog log stack trace. Default value: 20. Since PHP 7.2.0. listen.allowed_clients 9 stringThe log file for slow requests. Default value: listen.owner 1 intSet open file descriptor rlimit for child processes in this pool. Default value: system defined value. listen.owner 2 intSet max core size rlimit for child processes in this pool. Possible Values: 'unlimited' or an integer greater or equal to 0. Default value: system defined value. listen.owner 3 stringChroot 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. listen.owner 4 stringChdir to this directory at the start. This value must be an absolute path. Default value: current directory or / when chroot. 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. Default value: no. listen.owner 5 boolEnable the output decoration for workers output when is enabled. Default value: yes. Available as of PHP 7.3.0. listen.owner 6 boolClear 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. Default value: Yes. listen.owner 7 stringLimits 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. Default value: .php .phar listen.owner 8 stringIf AppArmor is enabled, it allows to change a hat. Default value: not set listen.owner 9 stringThe access log file. Default value: not set listen.group 0 stringThe access log format. Default value: listen.group 2%CPUlisten.group 3duration µslisten.group 4fastcgi envlisten.group 5scriptlisten.group 6content lengthlisten.group 7methodlisten.group 8memorylisten.group 9pool namelisten.owner 0header outputlisten.owner 1PIDlisten.owner 2query stringlisten.owner 3the glue between %q and %rlisten.owner 4request URIlisten.owner 5remote IP addresslisten.owner 6statuslisten.owner 7timelisten.owner 8timelisten.owner 9remote userIt's possible to pass additional environment variables and update PHP settings of a certain pool. To do this, you need to add the following options to the pool configuration file. |
