What I encountered in elasticsearch

1. php call Curl_setopt_array (): Unable to create temporary file

At first, I thought it was a yii framework issue, and then I didn't use the framework test.

It turns out that PHP has no write permission on temporary files and directly changes PHP. INI file, find sys_temp_dir = '. /tmp ', remove the semicolon; comment; I am E: \ phpstudy \ TMP;
