Prevent a package to be installed, upgraded, or removed:
aptitude install <package>=
Reconfigure broken package configuration:
It’s a handy tool if you have libapache2-mod-suphp and libapache2-mod-php installed, but you want to remove one of them, because sometimes Apache doesn’t know what you prefer; PHP or SuPHP.
dpkg-reconfigure <package>
Download a package without install:
apt-get -d install <packageName>

Make A New Partition with FDisk
Filed in Linux System Leave a comment
Assume we have /dev/sda:
1. fdisk /dev/sda
2. Create a new partition: type ‘n’
3. Choose logical or primary partition: type ‘l’ or ‘p’
4. Set the size you want,
5. Write the changes you have made: type ‘w’
6. Exit from fdisk, then make a new file system, for example: mkfs -t ext4 /dev/sda3

How to override php.ini:
1. If you allow user to override php.ini, then edit /home/user/public_html/.htacces :
suPHP_ConfigPath /home/user
Or if you don’t want user freely edit their php.ini file, then add these directive in virtual host configuration /etc/apache2/sites-enabled/:
<VirtualHost *:80>
…………………
IfModule mod_suphp.c
suPHP_ConfigPath /home/perpus
</IfModule>
</VirtualHost>
2. Copy /etc/php5/cgi/php.ini into /home/user/php.ini, then edit accordingly. Warning, if you just create a new php.ini and add a few options in it, then the other options (max upload, disabled function, etc) will be resetted in to default php configuration. So, it will be better if you copy from the main php configuration.
