不能与从本地主机PHP FTP_CONNECT连接到FTP [英] Can't connect to FTP with PHP ftp_connect from localhost
问题描述
我我一直试图做一些脚本通过FTP从我的本地主机的Apache CentOS中下载文件，我无法得到它的工作！
在code我现在用的是很一按任何基本的FTP请求中使用：
＆LT; PHP
$ IP = FTP_IP_HERE;
$端口= '21';
$超时= '90';
$ UN ='用户名';
$ PW ='密码';//连接到FTP
$ conn_id = FTP_CONNECT（$ IP，端口$，$超时）;//打开一个会话到外部FTP站点
$ login_result = ftp_login（$ conn_id，联合国$，$ PW）;//检查开
如果（（！$ conn_id）||（！$ login_result））{
打印FTP连接失败！;
出口（）;
}//打开被动模式传输
如果（ftp_pasv（$ conn_id，真实）== FALSE）{
打印被动FTP连接失败！;
出口（）;
}
我试过远程服务器上相同的脚本和它的工作！
我不知道这是否是任何Apache配置来完成，或者PHP本身的限制。

好吧，我有同样的问题，我发现我的情况的解决方案。在这里张贴帮助别人。
我的PHP脚本会失败，但我通过命令行可以很容易地FTP。我验证了我的防火墙没有阻止脚本，我并没有在我的日志得到任何PHP错误...
周围搜索后，就出现了我的问题是的SELinux 。我不想把它关掉，所以我检查的状态 httpd_can_network_connect 。
运行检查状态：
getsebool httpd_can_network_connect
如果你得到：
httpd_can_network_connect - ＆GT;离
这可能是你的问题。
注意：
如果你已经有这个在：
httpd_can_network_connect - ＆GT;上
或
的SELinux被禁用
那么这是不会解决您的问题...祝你好运找到你的解决方案。
的修复
启用 httpd_can_network_connect 运行：
setsebool httpd_can_network_connect = 1
再次测试脚本，看看它是否工作。这为我工作，所以我确信设置策略来保持这个功能。
setsebool -P httpd_can_network_connect = 1
注： -P 设置策略，以便它坚持在重新启动
I I've been trying to make some script to download files through FTP from my localhost Apache in CentOS and I can't get it to work!
The code I am using is the very one used by any basic ftp request:
<?php
$ip= FTP_IP_HERE;
$port='21';
$timeout='90';
$un='username';
$pw='password';
// Connect to ftp
$conn_id = ftp_connect($ip,$port,$timeout);
// Open a session to an external ftp site
$login_result = ftp_login ($conn_id, $un, $pw);
// Check open
if ((!$conn_id) || (!$login_result)) {
print "FTP connection failed!";
exit();
}
// turn on passive mode transfers
if (ftp_pasv($conn_id, true) == FALSE) {
print "Passive FTP connection failed!";
exit();
}
I tried the same script on remote server and it worked! I am not sure if it is any apache configuration to be done, or a PHP limitation itself.
UPDATE:
Here is the error log:
Warning: ftp_login() expects parameter 1 to be resource, boolean given in /var/www/html/ftp/FTP.php on line 16
Warning: ftp_get() expects parameter 1 to be resource, boolean given in /var/www/html/ftp/FTP.php on line 22

Ok, I had the same issue and I found the solution for my case. Posting it here to help others.
My PHP script would fail but I could easily FTP via command line. I verified my firewall wasn't blocking the script and I was not getting any PHP errors in my log...
After searching around, it appeared my issue was SELinux. I didn't want to turn it off so I checked the status of httpd_can_network_connect.
Check your status by running:
getsebool httpd_can_network_connect
If you get:
httpd_can_network_connect --> off
This may be your issue.
Note:
If you already have this on:
httpd_can_network_connect --> on
or
SELinux is disabled
Then this is not going to solve your issue... Good luck finding your solution.
The Fix
Enable httpd_can_network_connect by running:
setsebool httpd_can_network_connect=1
Test your script again and see if it works. This worked for me so I made sure to set a policy to keep this enabled.
setsebool -P httpd_can_network_connect=1
NOTE: -P sets the policy so it persists over a reboot
