php文件写入权限在aws ec2上被拒绝

Question

我尝试通过 php 在 aws ec2 上写入文件。

使用 nginx 和 php-fpm。

nginx www.conf

$ vi /etc/php-fpm-7.0.d/www.conf 

; Start a new pool named 'www'.
; the variable $pool can we used in any directive and will be replaced by the
; pool name ('www' here)
[www]

; Per pool prefix
; It only applies on the following directives:
; - 'access.log'
; - 'slowlog'
; - 'listen' (unixsocket)
; - 'chroot'
; - 'chdir'
; - 'php_values'
; - 'php_admin_values'
; When not set, the global prefix (or @php_fpm_prefix@) applies instead.
; Note: This directive can also be relative to the global prefix.
; Default Value: none
;prefix = /path/to/pools/$pool

; Unix user/group of processes
; Note: The user is mandatory. If the group is not set, the default user's group
;       will be used.
; RPM: apache Choosed to be able to access some dir as httpd
user = apache
; RPM: Keep a group allowed to write in log dir.
group = apache

文档根是...

$ ll
total 56
drwxrwxr-x 20 apache apache 4096 Jun 12 06:34 ...
... 
...

我的来源和结果是……

我试过了

$fileName = 'test.txt';
$contents = 'hello ';
$currentPath = dirname(__FILE__);

$fgc = file_get_contents($currentPath.'/'.$fileName);
file_put_contents($contents, $fgc);

结果

警告：file_get_contents(/xxx/test.txt)：打开流失败：/xxx/test.php 第 xx 行没有这样的文件或目录

试过

$fp = fopen($currentPath.'/'.$fileName, "w");
fwrite($fp, $contents);
fclose($fp);

结果

警告：fopen(/xxx/test.txt)：打开流失败：/xxx/test.php 第 xx 行的权限被拒绝

Answer 1

在PHP中，检查文件夹是否可写，如果不是，

if ( ! is_writable($currentPath.'/'.$fileName)){

    echo 'Not writable!!!';
}

然后，去ec2 via terminal，需要访问权限，使用命令

sudo chown -R www-data:www-data /var/www/html/YOUR-PROJECT-FOLDER
