FcgidBusyScanInterval command
Description: Scan busy timeout process interval
Syntax: FcgidBusyScanInterval seconds
Default: FcgidBusyScanInterval 120
Environment: Server Configuration
Status: External
Corresponding old command: BusyScanInterval
This module will perform FcgidBusyTimeout check in this interval.
FcgidBusyTimeout command
Description: Kill FastCGI applications that process requests for more than the time set by FcgidBusyTimeout
Syntax: FcgidBusyTimeout seconds
Default: FcgidBusyTimeout 300
Environment: Server configuration, virtual host
Status: External
Corresponding old command: BusyTimeout
This is the maximum time limit for processing requests. If the FastCGI request exceeds the number of seconds set by FcgidBusyTimeou, the request will be terminated. The time when the check is performed will be defined by FcgidBusyScanInterval, and the request processing is valid within the set time. The purpose of this command is to terminate a hung application. The default timeout may need to be increased so that applications can take longer to process requests.
FcgidBusyScanInterval 120 #Corresponds to FcgidBusyTimeout, checks every 120 seconds
FcgidBusyTimeout 300 #Fastcgi requests exceeding 300 seconds will be terminated
FcgidConnectTimeout command
Description: Fastcgi service times out after waiting for the set time parameter (Fastcgi connection timeout)
Syntax: FcgidConnectTimeout seconds
Default: FcgidConnectTimeout 3
Environment: Server configuration, virtual host
Status: External
Corresponding old command: IPCConnectTimeout
This is the maximum cycle time set by the Fastcgi module in Windows when it tries to connect to an application. When the waiting time exceeds this time, a timeout will occur. (This command is not suitable for UNIX)
FcgidErrorScanInterval command
Description: Scan and exit suspended processes within the interval
Syntax: FcgidErrorScanInterval seconds
Default: FcgidErrorScanInterval3
Environment: Server Configuration
Status: External
Corresponding old command: ErrorScanInterval
This is the interval module that will handle pending process termination. Terminate any process on which FcgidIdleTimeout or FcgidProcessLifeTime is waiting.
FcgidIdleScanInterval command
Description: Scan interval for idle timeout process
Syntax: FcgidIdleScanInterval seconds
Default: FcgidFixPathinfo120
Environment: Server Configuration
Status: External
Corresponding old command: IdleScanInterval
Within this set time interval, the module will search for processes that have exceeded the maximum valid time set by FcgidIdleTimeout or FcgidProcessLifeTime, and processes that exceed this time will be terminated.
FcgidIdleTimeout command
Note: The idle Fastcgi program will be killed after exceeding the set time
Syntax: FcgidIdleTimeout seconds
Default: FcgidIdleTimeout 300
Environment: Server Configuration
Status: External
Corresponding old command: IdleTimeout
After the set idle time, the Fastcgi program that does not process the request will be terminated. The check of the idle process is used in conjunction with the FcgidIdleScanInterval above.
FcgidIdleScanInterval 120 #Corresponds to FcgidIdleTimeout, checks every 120 seconds
FcgidIdleTimeout 300 #fastcgi idle process that exceeds 300 seconds will be terminated
FcgidInitialEnv command
Description: Pass the value of the environment variable and some optional values to Fastcgi

Fastcgi applications attempting to read or write will wait for the set time to do the work,
FcgidFixPathinfo command
Description: Mirror PHP cgi.fix_pathinfo setting
Syntax: FcgidFixPathinfo 1
Default: FcgidFixPathinfo0
Environment: Server Configuration
Status: External
Corresponding old command: PHP_Fix_Pathinfo_Enable
The pathinfo mode is not supported by default and only the normal url access mode is supported. If this command is used here, the settings in php.ini will be used, as follows:
cgi.fix_pathinfo=1
pathinfo mode refers to non-traditional URL access modes, such as pseudo-static, rewrite
FcgidMaxProcesses command
Note: The maximum number of processes for php-cgi
Syntax: FcgidMaxProcesses value
Default: FcgidMaxProcesses 1000
Environment: Server Configuration
Status: External
Corresponding old instruction: MaxProcessCount
This command sets the maximum number of FastCGI processes that can be activated at one time when running the program. The more RAM you have, the higher you can set the value.
FcgidMaxProcessesPerClass directive
Note: The maximum number of FCGI processes that each virtual host can open
Syntax: FcgidMaxProcessesPerClass value
Default: FcgidMaxProcessesPerClass 100
Environment: Server Configuration
Status: External
Corresponding old instruction: DefaultMaxClassProcessCount
The default is 100. Each virtual host can open up to 100 Fastcgi processes, that is, a single customer can have 100 PHP service requests at the same time. I would suggest values from 8 to 20. NOTE: If there are more requests at the same time, they will be queued instead of rejected. (The size of the value cannot be greater than the value set by FcgidMaxProcesses)
FcgidMinProcessesPerClass directive
Description: Opposite of FcgidMaxProcessesPerClass
Syntax: FcgidMaxProcessesPerClass value
Default: FcgidMaxProcessesPerClass3

FcgidMaxRequestInMem directive
Description: The maximum size stored in memory for each request
Syntax: FcgidMaxRequestInMem bytes
Default: FcgidMaxRequestInMem 65536
Environment: Server Configuration
Status: External
This module reads the entire request body from the client and sends it to the application. Normally, the request body will be stored in memory. Once the amount of the request body read from the client exceeds the number of bytes set by FcgidMaxRequestInMem, the remainder of the request body will be stored in a temporary file.
FcgidMaxRequestLen command
Description: Maximum length of HTTP request
Syntax: FcgidMaxRequestLen bytes
Default: FcgidMaxRequestLen 131072
Environment: Server Configuration
Status: External
If the HTTP request size exceeds this amount, the request will fail and a 500 Server Error will occur. Error usually occurs when uploading files.
Warning: Before 2.3.6, the default was 1GB, and now the default is 128K. Users should use this command to set a more reasonable limit. For example, when I use 2.3.6, I should use this parameter to set it to upload larger files. data.
FcgidMaxRequestsPerProcess directive
Description: The maximum number of requests per php-cgi process
Syntax: FcgidMaxRequestsPerProcess value
Default: FcgidMaxRequestsPerProcess 0
Environment: Server configuration, virtual host

FcgidSpawnScoreUpLimit command
Description: Control value that allows the process to spawn speed
Syntax: FcgidSpawnScoreUpLimit value
Default: FcgidSpawnScoreUpLimit 10
Environment: Server Configuration
Status: External
Generate speed control value. When a process is spawned or terminated, this value will increase and decrease over time; when this value is higher than FcgidSpawnScoreUpLimit, the spawning process will stop for a while until the existing process is idle or The value of FcgidSpawnScoreUpLimit is lower than the set value. The higher this number is, the faster the build process will be.
FcgidSpawnScore command
Description: Weight of process generation speed
Syntax: FcgidSpawnScore value
Default: FcgidSpawnScore 1
Environment: Server Configuration
Status: External
Generate speed weights. For each process, this value is added to the spawn speed control value (FcgidSpawnScoreUpLimit). The larger this value, the faster the CGI generation speed.
FcgidTerminationScore command
Description: Increase the value of each terminated process activity
Syntax: FcgidTerminationScore value
Default: FcgidTerminationScore 2
Environment: Server Configuration
Status: External
Death weight. The larger this value is, the slower the CGI process will be generated.

FcgidMaxRequestLen 1500000
Attachment:
1. AddHandler command
Description: Establish a mapping between file extensions and specific processors
AddHandler fcgid-script .fcgi .php
The explanation of the above statement is: Once the above definition is placed in your http.conf file, all files containing .fcgi, .php extensions will be regarded as FCGID programs.
2. AddType Command
Description: Establishes a mapping between a given file extension and a specific content type
AddType application/x-httpd-php .php
The explanation of the above statement is: Once the above definition is placed in your http.conf file, all files containing the .php extension will be regarded as PHP type programs.
