PHP 引擎的实时日志

Question

有什么方法可以在线观看php活动吗？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，看看 apache 打印了什么。

所以，我正在为php网页寻找类似的东西。php 是 7.2

UPDATE1：

尝试使用tail -f /var/log/messages观看系统日志，当从浏览器重新加载页面时，我在终端中收到许多与此类似的消息。

这是一个丑陋的信息！我想我必须用一些路径跑semanage fcontext -a -t。不确定到底是哪条路径！

UPDATE2：

以下命令提供了更清晰的日志

[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

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，从日志消息中可以明显看出...

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，完全按照它所说的去做......看看这是否能解决其他错误。

如果在运行这些命令后仍然存在其他错误，请按照显示的非常清晰的错误消息中的说明进行操作。

Answer 2

这是我笔记中的一个 php « 尾巴»可以玩。

它类似于尾巴 -n 5 访问.log

这将回答最后 5 行访问.log。

要使其像尾巴 -f一样，只需使用循环即可。

$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，整个文件不会像尾巴一样被占用在内存中。

SplFileObject
