Gunjan — Sun, 22 Jan 2012 09:24:01 +0000

After enabling the suphp on the server,many time 500 Internal Server Error occur due to the incorrect permission,ownership and incorrect php module defined in the .htaccess file and we can’t make the changes manually therefore we can use the following script to make the all the changes server.

linux7802@server[~]#cat /root/suphppermission.sh

#!/bin/bash

# Reset the directory permissions.
chmod 755 /opt/suphp
find /opt/suphp -type d -exec chmod 755 {} \;

# Reset permission,ownership for cPanel user
for user in `/bin/ls /var/cpanel/users`; do

chown -R ${user}:${user} /home/${user}/public_html
chmod 755 /home/${user}/public_html
find /home/${user}/public_html -type f -exec chmod 644 {} \;
find /home/${user}/public_html -type d -exec chmod 755 {} \;

# Remove php_values in the .htaccess file.
find /home/${user}/public_html -name ‘.htaccess’ -exec sed -ie ‘s/php_value/#php_value/’ {} \;
find /home/${user}/public_html -name ‘.htaccess’ -exec sed -ie ‘s/php_flag/#php_flag/’ {} \;
done

How to access Awstats From Outside the control panel

How to access Awstats From Outside the control panel

Accessing Awstats from outside the control panel is easy.

Step 1.
Download awstats from http://awstats.sourceforge.net

Step 2.
Uncompress awstats-5.6.tgz

Step 3.
Copy the contents of the uncompressed cgi-bin folder from your hard drive to the user cgi-bin directory (this includes awstats.pl, awstats.model.conf, and the lang, lib and plugins sub-directories).

Step 4.
If necessary (should not be needed with most setups), edit the first (top-most) line of awstats.pl file that is
#!/usr/bin/perl
to reflect the path were your Perl interpreter is installed. Default value works for most of Unix OS, but it also might be #!/usr/local/bin/perl

Step 5.
Move AWStats icon sub-directories and its content into a directory readable by your web server, for example /home/users/public_html/icons

Step 6.
Copy awstats.model.conf file into a new file named awstats.myvirtualhostname.conf. This new file must be stored in /home/user/public_html/cgi-bin.

Step 7.
Edit this new config file with your own setup :
- Change LogFile value with full path of your web server log file (The path is: LogFile=”/usr/local/apache/domlogs/domain.com”).
- Check if LogFormat has the value “1″ (it means “NCSA apache combined/ELF/XLF log format”).
- Change DirIcons parameter to reflect relative path of icon directory. (DirIcons=”/icons”)
- Edit SiteDomain parameter with the main domain name or the intranet web server name used to reach the web site to analyze (Example: www.mydomain.com).

IMPORTANT!
- Change DirData to use the same Statics file than Cpanel Awstats and do not loose any entry.
(DirData=”/home/user/tmp/awstats/”)

Step 8.
Access AwStats by the URL:
www.yourdomain.com/

Send mail by using phpmail function.

Gunjan — Mon, 21 Sep 2009 04:28:58 +0000

You can create a simple php mail form by using following code..

————————–

$to = ‘supp0rt@xyz.com’;
$subject = ‘The test for mail function’;
$message = ‘Hello’;
$headers = ‘From: test@abc123.com’ . “\r\n” .
‘Reply-To: test@testforever123.com’ . “\r\n” .
‘X-Mailer: PHP/’ . phpversion();
mail($to, $subject, $message, $headers);
?>

————————–

If you are not able to receive the E-mail then you need to check whether your server is allowing to send an E-mail by using phpmail() or not?’ if you are having root login then check the servers main php.ini file.

root@Gunjan []# php -i | grep php.ini
Configuration File (php.ini) Path => /usr/local/lib
Loaded Configuration File => /usr/local/lib/php.ini

root@Gunjan []# cat /usr/local/lib/php.ini | grep disable_function
disable_functions=”system,passthru,popen,proc_close,proc_get_status,proc_nice,proc_open,proc_terminate,shell_exec,highlight_file,phpmail”

and remove the phpmail() from server mail php.ini file and restart the Apache web server.

If you are not having root login details then contact your hosting provider and ask them to enable the phpmail() for your hosting account.

You can also send me an E-mail at nsk.gunjan@gmail.com if you have any queries…
