PHP 5 Local

As php5 compiled in the cgi mode customers cannot to use .htaccess directives like php_admin, php_value, php_flag. In phpsuexec setup (for main php) it is overridden by allowing customers place custom php.ini with the variables.

However if you build the php5 as the secondary php it will not have such ability. So how to solve it? To write very simple wrapper to pass php.ini line of the current directory if exists.

The steps to be done after php5 setup.

Moving php5 binary:

mv /usr/local/cpanel/cgi-sys/php5 /usr/local/cpanel/cgi-sys/php5.bin

Then creating wrapper file in the /usr/local/cpanel/cgi-sys/php5 with the following content:

#!/bin/bash

# This will fake the name & path and hide the /usr/local/cpanel/cgi-sys/php5 path!
export SCRIPT_NAME=$REQUEST_URI
export SCRIPT_FILENAME=$PATH_TRANSLATED
export PWD=`echo $PATH_TRANSLATED|egrep -o “(.*?/)”`

if [ -f “$PWD/php.ini” ]; then
exec /usr/local/cpanel/cgi-sys/php5.bin -c $PWD
else
exec /usr/local/cpanel/cgi-sys/php5.bin
fi

Save the file and change the permissons:

chown root:wheel /usr/local/cpanel/cgi-sys/php5*;
chmod 755 /usr/local/cpanel/cgi-sys/php5*;

We are done! By default php5 will use the global php.ini, but if the customer has the own php.ini in its folder php5 will use it instead

Wild Card DNS

For the DNS, edit the DNS zone file and add the following:
Code:

* IN A x.x.x.x

(where x.x.x.x is the IP for the hosting account using the wildcard)

Edit your httpd.conf config file for your web server and add a
server alias wildcard for the host you want to have wildcards:
Code:

ServerAlias *.mydomain.com

OpenDNS error

change etc/named.conf from:

options {
directory “/var”;
auth-nxdomain no;
pid-file “/var/run/named/named.pid”;

to this:

options {
directory “/var”;
auth-nxdomain no;
pid-file “/var/run/named/named.pid”;
allow-recursion { 127.0.0.1; };

mysql showing wrong version on cpanel

edit /home/username/.cpanel-datastore/_usr_sbin_mysqld_–version

if you have multiple accounts with problem

find ./*/.cpanel-datastore/ | grep _usr_sbin_mysqld_–version | awk ‘{system (“rm ” $1)}’

Ssh not restarting in vps

Please do this commands in shell

Kernel compilation

Go to the /usr/src directory
Unpack the source code with tar -xvzf linux-2.x.x.tag.gz.
Move to the /usr/src/linux sub-directory.

make mrproper
make menuconfig
make all     — make vmlinux
— make modules
— make bzimage
make modules_install
make install
cp /usr/src/linux/arch/i386/boot/zImage /zImage

Making an initrd Image

An initrd image is needed for loading your SCSI module at boot time or if you are compiling the kernel with ext3 support as a module. If you do not need an initrd image, do not make one and do not edit lilo.conf or grub.conf to include this image.

Use the /sbin/mkinitrd shell script to build an initrd image for your machine. To use this command, the loopback block device must be available.

To build the new initrd image, run /sbin/mkinitrd with parameters such as this:

/sbin/mkinitrd /boot/initrd-2.4.18-0.12-jul2001.img 2.4.18-0.12-jul2001

In the above example, /boot/initrd-2.4.18-0.12-jul2001.img is the file name of the new initrd image. 2.4.18-0.12-jul2001 is the kernel whose modules (from /lib/modules) should be used in the initrd image. This is not necessarily the same as the version number of the currently running kernel.

Unable to load iptables module (ipt_state), aborting

Starting APF:Unable to load iptables module (ipt_state), aborting.

Just enable the no kernel option in /etc/apf/conf.apf
It should be like this:
SET_MONOKERN=”1″
Save and then restart apf: /usr/sbin/local/apf -r
