2. Check /runtime/logs/app.log, and report an error:[warning][yii\validators\FileValidator::validateValue]Missing the temperature folder to store the uploaded file: 360wallpaper(0).jpg

Figure 2

4. Check the upload_tmp_dir value of file uploads; upload_tmp_dir =, the temporary directory used to store the file when uploading the file. Any user running PHP must be writable. If not specified, PHP will use the default value of the system. The default temporary directory of the system is /tmp, check the permissions of the current version /tmp directory, as shown in Figure 3

Figure 3

drwxrwxr-x   1 root root

5. Check the permissions of the previous version /tmp directory, there is a difference in permissions, and the analysis draws the conclusion, because the /tmp directory is overwritten and the permissions are modified, as shown in Figure 4

Figure 4

drwxrwxrwt   1 root root
