Setting up a DNS Server on Red Hat Enterprise Linux 5.5

Time Required: 20 minutes

Class Materials:

  • Red Hat Enterprise Linux 5.5 64-bit install media

The following steps show how to install your own DNS server into Red Hat Enterprise Linux 5.5

These steps were developed as part of my ten part blog series on installing your own Oracle 11gR2 RAC cluster on VMWare Workstation 8.

I am re-blogging this as a separate post for the sake of clarity to those not interested in the RAC components.

First, locate and mount your RHEL 5.5 install media.

Oracle 11gR2 RAC – sshUserSetup.sh script to swap ssh keys between hosts

Oracle 11gR2 RAC Grid install includes a useful script to establish and exchange ssh keys between hosts of the cluster.

The process to set up and exchange ssh keys between hosts to facilitate unchallenged logins between trusted users has been well documented already. Oracle simply provides a handy wrapper script over the whole process.

Although the main Grid install process will set up ssh keys, this is a useful verification step to ensure all nodes are reachable, as well as a prerequisite to having the cluvfy script succeed.

Oracle 11gR2 – clean up after failed database install

So your Oracle database install crashes and burns and you are left with a mess to clean up.

Oracle now provides some canned de-install scripts to try to do this for you, but in my experience they are about as useful as a chocolate teapot.

First, let’s verify where Oracle did the install.  Check the oraInst.loc file in the /etc directory:

Oracle 11gR2 RAC install – installer hangs at 65%

During the install of Oracle 11gR2 RAC Grid, the installer hangs at 65%, with no errors on screen or in the log file.

The problem is the Linux firewall interfering with the install.

Before running the runInstaller script, make sure the firewall is disabled on ALL nodes. Connect as root and disable it as follows:

[root@tbird1 ~]# service iptables stop
Flushing firewall rules: [  OK  ]
Setting chains to policy ACCEPT: filter [  OK  ]
Unloading iptables modules: [  OK  ]

 

To make sure it stays permanently disabled use the following:

[root@tbird1 init.d]# chkconfig iptables off
