In-Depth Information
If you have a relatively recent version of Red Hat or Fedora, you can also use the
yum
(short for Yellowdog Updater Modified) program to automatically download and in-
stall the necessary packages from the Internet. This is very convenient because you
don't have to spend time digging up your installation CDs. More importantly, the latest
version of a package generally has patches for known bugs and security vulnerabilities.
If you've never used
yum
before, you need to configure it first. First, type
su -
to log in
as the system root user, and then update your
/etc/yum.conf
configuration file by
typing:
#
wget http://www.fedorafaq.org/samples/yum.conf
#
/bin/mv /etc/yum.conf /etc/yum.conf.bak
#
/bin/mv yum.conf /etc
Now, update the
yum
indexes that list packages and the locations that they can be
downloaded from:
#
rpm --upgrade --verbose --hash http://www.fedorafaq.org/yum

Once you've configured
yum
, you can download and install all the programs you need
by simply specifying them from the command line:
#
yum update mysql mysql-server httpd php php-mysql
[root@saiedpc ~]# yum update mysql mysql-server httpd php php-mysql
