php引擎的实时日志

Question

有没有任何方法可以在线观看php活动？我正在寻找类似apache日志的东西，我可以在终端中运行tail -f /var/log/httpd/access.log，然后在浏览器中打开URL并查看apache打印的内容。

因此，我正在为php网页寻找类似的东西。php为7.2

UPDATE1：

尝试使用tail -f /var/log/messages查看系统日志时，当页面从浏览器重新加载时，我在终端中得到许多类似于此的消息。

这是个丑陋的信息！我想我必须用一些路径运行semanage fcontext -a -t。不知道到底是哪条路！

UPDATE2：

下面的命令提供了一个更清晰的日志

[root@localhost html]# sealert -l e254cabb-7005-4a3c-8f91-8620c924c5e0
SELinux is preventing /usr/sbin/httpd from write access on the file /var/www/html/ow_includes/config.php.

*****  Plugin httpd_write_content (92.2 confidence) suggests   ***************

If you want to allow httpd to have write access on the config.php file
Then you need to change the label on '/var/www/html/ow_includes/config.php'
Do
# semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/ow_includes/config.php'
# restorecon -v '/var/www/html/ow_includes/config.php'

*****  Plugin catchall_boolean (7.83 confidence) suggests   ******************

If you want to allow httpd to unified
Then you must tell SELinux about this by enabling the 'httpd_unified' boolean.

Do
setsebool -P httpd_unified 1

*****  Plugin catchall (1.41 confidence) suggests   **************************

If you believe that httpd should be allowed write access on the config.php file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'httpd' --raw | audit2allow -M my-httpd
# semodule -i my-httpd.pp

Answer 1

这是一个SELinux问题，从日志消息中可以看出.

SELinux is preventing /usr/sbin/httpd from write access on the directory /var/www/html/ow_userfiles/plugins/admin.#012#012*****  
...
If you want to allow httpd to have write access on the admin directory
Then you need to change the label on '/var/www/html/ow_userfiles/plugins/admin'

 semanage fcontext -a -t httpd_sys_rw_content_t '/var/www/html/ow_userfiles/plugins/admin'
 restorecon -v '/var/www/html/ow_userfiles/plugins/admin'

从第一个错误开始，按照它的说法做。看看这能不能解决其他人。

如果在运行这些命令后仍然存在其他错误，请按照您收到的非常清楚的错误消息中的指示执行。

Answer 2

这里是一个php的尾巴，从我的笔记周围玩。

它类似于 -n 5 access.log

这将回答access.log的最后5行。

要使它像-f一样运行，只需使用一个循环。

$check = "access.log";
$end = "5";

$fp= fopen($check, "r");
$count=0;
while($line = fgetss($fp))
$count++;
// echo "Total lines ".$count.PHP_EOL;
fclose($fp);

$start = $count - $end;

$file = new SplFileObject($check);
$file->seek($start);
for($i = 0; !$file->eof() && $i < $end; $i++) {
  echo $file->current(); 
  $file->next();
}

它也非常快，整个文件没有在内存中，就像尾巴。
