Linux Operating Platform Enterprise 5.4, IP address 192.168.101.222, domain name: abc.com

1. Set up a DNS server:

[Root @ Eleven ~] # Mkdir/mnt/cdrom

[Root @ Eleven ~] # Mount/dev/cdrom/mnt/cdrom/

Mount: block device/dev/cdrom is write-protected, mounting read-only

Edit yum

[Root @ Eleven ~] # Vim/etc/yum. repos. d/rhel-debuginfo.repo

[Root @ Eleven ~] # Cd/mnt/cdrom/Server/

[Root @ Eleven Server] # yum install bind-chroot caching-nameserver-y

[Root @ Eleven Server] # cd/var/named/chroot/etc/

[Root @ Eleven etc] # cp-p named. caching-nameserver.conf named. conf

[Root @ Eleven etc] # vim named. conf

(Red indicates the modified content)

Modify the region declaration File

[Root @ Eleven etc] # vim named. rfc1912.zones

Generate Database

[Root @ Eleven etc] # cd ../var/named/

[Root @ Eleven named] # cp-p localhost. zone abc.com. db

[Root @ Eleven named] # vim abc.com. db

Modify to the following content:

Modify vim/etc/resolv. conf

Modify host name:

Vim/etc/sysconfig/network

Restart system: init 6

[Root @ mail ~] # Service named start

Starting named: [OK]

[Root @ mail ~] # Chkconfig named on

DNS Installation Complete

2. Install the required rpm package, which includes the following:

[Root @ mail ~] # Mount/dev/cdrom/mnt/cdrom/

Mount: block device/dev/cdrom is write-protected, mounting read-only

[Root @ mail ~] # Yum install-y httpd mysql-server mysql-devel openssl-devel dovecot perl-DBD-MySQL tcl-devel libart_lgpl libart_lgpl-devel libtool-ltdl-devel skip CT

3. Disable sendmail and disable it with the Automatic startup function of the system:

[Root @ mail ~] # Service sendmail stop

[Root @ mail ~] # Chkconfig sendmail off

4. Install the rpm package used for the following development:

Development Libraries

Development Tools

Legacy Software Development

X Software Development

Run the command yum grouplist to view the information. If no command is available, run the command yum groupinstall "packge_group_name"

5. Start the mysql database and set the password for the root user of mysql:

[Root @ mail ~] # Service mysqld start

[Root @ mail ~] # Chkconfig mysqld on

Set the new password to "RedHat". Because there is no old password, press Enter when you need to enter the old password.

[Root @ mail ~] # Mysqladmin-u root password 'redhat'

Yes.
