max_execution_time = 30 ; Maximum execution time of each script, in seconds
max_input_time = 60 ; Maximum amount of time each script may spend parsing request data
;max_input_nesting_level = 64 ; Maximum amount of memory a script may consume (128MB)
; Maximum size of POST data that PHP will accept.
post_max_size = 105M
; Generally speaking, when uploading files, you first need to ensure the upload memory. Check the default configuration of PHP.INI. The default memory_limit is 128M, which is the amount of memory that can be consumed by executing a script. If the upload limit is 100M, then such a large amount of memory is enough (or generally speaking, for example, if multiple files are uploaded at the same time, it may not be enough).
2. Adjust the execution time set_time_limit

max_execution_time is set to 30 seconds by default. For uploading 100M files, judging from the current network conditions, it is almost impossible to upload 100M files in 30 seconds. The 10M bandwidth is completely symmetrical, and one megabyte per second takes one and a half minutes. . Therefore, even if this setting is adjusted, it is difficult to estimate the actual execution time, and if the adjustment is too long, it is not friendly to APACHE. Therefore, it is recommended not to adjust max_execution_time, but only use it in PHP programs: set_time_limit(0); Make temporary adjustments. Setting 0 means there is no time limit. Of course, from the perspective of program execution, setting 0 solves the timeout problem, but it is not actually a good solution. If the program supports breakpoint resuming, then setting 600 seconds or 3600 seconds seems to be a better idea, and the breakpoint will automatically break when the timeout occurs. Just resume the upload.

3. Restart the APACHE server
