Install php 5.2 in Ubuntu

Installing PHP 5.2

Adding the Dotdeb repository

We’re going to add the Dotdeb repository, which will provide the latest versions of PHP for Debian. We need to modify the sources.list file by running the following command

vi /etc/apt/sources.list

Once you have sources.list file open, add the two following lines

deb http://packages.dotdeb.org stable all
deb-src http://packages.dotdeb.org stable all

Now let’s update the packet database to add those of Dotdeb. The version of Dotdeb packets being always superior to those of Debian, the Dotdeb versions will be automatically selected during the installation of PHP

Installing PHP 5

After having added the Dotdeb repository, we can move on to installing PHP:

apt-get install php5-mysql
apache2ctl restart

Test PHP by checking the phpinfo page

MySql >= 4.1 Client does not support authentication protocol…

If you upgrade your MySql server to >= 4.1 you might get the following error:

Client does not support authentication protocol requested by server; consider upgrading MySQL client

This happens because the latest versions of MySql uses a new format for the password (it’s a longer hash). In order for old clients to continue to use the newer server, you have to set the passwords on the server to their old format or upgrade your client. Because upgrading the client can sometimes be a pain, it’s often easier to just update the passwords to the old format on the server.

Run mysql and login as root:
mysql -u root -p

Then, paste the following command, editing as necessary, to change the password of the user to the old format.

UPDATE mysql.user
SET password=OLD_PASSWORD(’somepassword’)
WHERE user=’someuser’
AND host=’somehost’;

After you have set the passwords to the old format, flush the tables.

flush privileges;

Then exit the mysql client with “quit” and you are set.

For windows.

In my.ini file in the mySQL directory (C:\Program Files\MySQL\MySQL Server 4.1\my.ini),
add the following line after [mysqld]

old_passwords

top: error while loading shared libraries: libncurses.so.4: cannot open shared object file: Error 40

This error is received when top command is executed.

top
top: error while loading shared libraries: libncurses.so.4: cannot open shared object file: Error 40

Fix.

locate libncurses.so.5

lib/libncurses.so.5
/usr/lib/libncurses.so.5
/usr/lib/libncurses.so.5.5

create symblinks
ln -s /lib/libncurses.so.5 /lib/libncurses.so.4
ln -s /usr/lib/libncurses.so.5 /usr/lib/libncurses.so.4

the location may be different. Just create symblink from libncurses.so.4 to libncurses.so.5

load the configuration
ldconfig

Uninstall APF

rm -rf /etc/apf
rm -f /etc/cron.daily/fw
rm -f /etc/init.d/apf
rm -f /usr/local/sbin/apf

change site’s IP address in Plesk

In order to change the IP.

Plesk > click Domain.com > setup > IP address dropdown box.

However, if you have only one IP, dropdown will not be shown.

If you are the admin and you see only one IP and no drop down under IP in setup.
First you need to add the IP in the pool of client.

Let me explain it more clearly.

eg: client >>> john is having domains>> abc.com , xyz.com

If you need to change the IP of abc.com

clients > John > abc.com > setup > IP

Here is you see only one IP, then that means only one IP is in the pool of John. so first add the required IP in the pool of John

clients > John > IP pool > Add new IP address.

Now this added IP will in the dropdown at

clients > John > abc.com > setup > IP

About Partition Image

Partition Image is a Linux/UNIX utility which saves partitions in the EXT2, Reiserfs, NTFS, HPFS, FAT16, and FAT32 file system formats to an image file.

The image file can be compressed with gzip or bzip2 in order to save disk space, and it can be split in order to fit onto a series of floppy disks. This program is mainly used for backup purposes.

A boot disk is also provided, allowing you to run Partition Image without Linux installed on the hard disk.
