1. SceneIn front, I have a blog post about how to solve the wordpress upload file size limit http://blog.51cto.com/superpcm/2094252, but when I set up the following architecture, upload a picture larger than 2M appears this situation:2. SolutionConfirmed the PHP and Nginx configuration files of Web01 and web02 several times, confirming that there is no problemBef
Configure PHP.ini files (for example, files of the size of 500M below)
Look for the following options and modify the->
File_uploads = on; open File upload option
upload_max_filesize = 500M; upload file upper limit
If you want to upload a larger file, only the above two i
Label:A file if a few 10 trillion words, upload may be wrong, because the execution time is not enough,For example, I encountered the Ecshop database file is more than 40 m first execution failure.So simply set everything up at once. Look for the following in php.ini (PHP configuration file in Apache) file:"Max_executi

Maximum Post size:Post_max_size=2mChange to the size you need, the second is generally larger than the first value3. There is also a placeMax_execution_time=30This is the maximum execution time, if the file is too large to uploa
1. Modify Max_execution_time
In PHP, the default page execution time is 30 seconds, more than 30 seconds, and the script stops executing.This will cause you to be unable to open the page. Then we can modify the Max_execution_timeLook in the php.ini.
Max_execution_time
The default is 30 seconds.
Max_execution_time = 0
0 means no Limit
2. Modify Post_max_size
Post_max_size sets the maximum size allowed
encryption. Operating systems that support NTFS disk formats include windows nt, windows xp, WINDOWS vista, and WINDOWS 7. Therefore, NTFS is still the mainstream disk format, and a large number of users are using it.

security and stability, and it is not easy to generate file fragments during use. It records user operations and imposes strict restrictions on user permissions, so that each user can only perform operations according to the permissions granted by the system, fully protecting the security of the system and data. In addition, the most intuitive advantage of NTFS for most users is that the size of a single
number of users in use.NTFS file system benefits: NTFS partitioning has high security and stability and is not easy to produce file fragmentation in use. It can record the operation of the user, through a very strict restrictions on user rights, so that each user can only follow the system-assigned permissions to operate, and fully protect the system and data security. In addition, for most users, the most
Use FAT32 File System
When saving files, the computer usesFile SystemControls how files or folders are saved on the hard disk. Older versions of MS-DOS and Windows use the unique fat16 file system. By default, fat16 is used for Windows 98, but FAT32 is used. The FAT32
their corresponding cluster is in an unassigned state.Root Folder AreaBrief introduction:In the FAT32 file system, the location of the root folder is no longer rigidly fixed and can be stored in an addressable cluster within a partition, except that the root folder is usually the oldest (formatted) folder table. So, what we're seeing is basically the first cluster of root folders next to FAT2, which is the

If a file occupies many clusters, the first FAT entry records the number of the next FAT item (both cluster number), and if the file is closed, it is denoted by "0F FF FF FF".8, after the partition format, the user file
structure of the FAT32 file system continues the basic structure of the FAT file system, as shown in figure 4, which consists of the following three parts:(1) DBR (Dos Boot Record), including jump command, vendor logo, OS version number, BPB (Bios Parameter Block), extension BPB, Boot program and terminator;(2) FAT table: The ing table of the actual data storage

8, after the partition format, the user file
manages the storage space of the Data zone by cluster, and the cluster is the basic unit of space allocation and recovery. That is, a file always occupies several clusters. The remaining space of the last cluster used by the file will not be used, but will be wasted. From the table 6-16, we can see that using FAT32 in logical partitions of hard disks with the sa

Microsoft in 2001 for its own XP system local disk default use of the NTFS file system, but 12 years later, the market of USB mobile devices and SD card external storage is still in use in the FAT32 file format, what is the reason for hardware vendors to choose outdated file system format?Obviously, this is not the har

A fat table item value indicates a cluster number occupied by the file and specifies the location of the next cluster number.
The fat table records the usage of each cluster on the disk in sequence. Use 32-bit binary codes for the usage of each cluster. Do not enter zero in the corresponding location of the unallocated cluster; enter a
