OS Installation Detailed instructions for installing Fedora are available at http://docs.fedoraproject.org/install-guide/f12/ in a number of languages. The abbreviated version is as follows... Point your browser to http://fedoraproject.org/en/get-fedora-all, locate the Install Media section and download the install DVD that matches your hardware. Burn the disk image to a DVD http://docs.fedoraproject.org/readme-burning-isos/en-US.html and boot from it. Or use the image to boot a virtual machine as I have done here. After clicking through the welcome screen, select your language and keyboard layout http://docs.fedoraproject.org/install-guide/f12/en-US/html/s1-langselection-x86.html Insert graphic here Assign your machine a host name. http://docs.fedoraproject.org/install-guide/f12/en-US/html/sn-networkconfig-fedora.html I happen to control the clusterlabs.org domain name, so I will use that here. Insert graphic here You will then be prompted to indicate the machine’s physical location and to supply a root password. http://docs.fedoraproject.org/install-guide/f12/en-US/html/sn-account_configuration.html Now select where you want Fedora installed. http://docs.fedoraproject.org/install-guide/f12/en-US/html/s1-diskpartsetup-x86.html As I don’t care about any existing data, I will accept the default and allow Fedora to use the complete drive. IMPORTANT: If you plan on following the DRBD or GFS2 portions of this guide, you should reserve at least 1Gb of space on each machine from which to create a shared volume. Insert graphic here The next step is to configure networking. Do not accept the default. Cluster machines should never obtain an ip address via DHCP. Here I will use the internal addresses for the clusterlab.org network. Insert graphic here Next choose which software should be installed. Deselect the default “Office and Productivity” as its not appropriate for a cluster node. You will want to select the “Updates” channel though. We’ll install any needed software later. After you click next, Fedora will begin installing. Insert graphic here Insert graphic here Once the node reboots, follow the on screen instructions http://docs.fedoraproject.org/install-guide/f12/en-US/html/ch-firstboot.html to create a system user and configure the time. It is highly recommended to enable NTP on your cluster nodes. Doing so ensures all nodes agree on the current time and makes reading log files significantly easier. Insert graphic here Click through the next screens until you reach the login window. Click on the user you created and supply the password you indicated earlier.
Cluster Software Installation Installing the cluster in future versions of Fedora will be significantly easier now that the entire stack has been accepted into the distribution. However for now there are still some hoops to jump through. Start a terminal by going to Applications -> System Tools -> Terminal Insert graphic here That was the last screenshot by the way, from here on in we’re going to be working from the terminal. Switch to the super user (aka. "root") account. You will need to supply the password you entered earlier during the installation process. su - [beekhof@pcmk-1 ~]$ su - Password: [root@pcmk-1 ~]# Note that the username (the text before the @ symbol) now indicates we’re running as the super user “root”. + +[root@pcmk-1 ~]# ip addr +1: lo: mtu 16436 qdisc noqueue state UNKNOWN + link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00 + inet 127.0.0.1/8 scope host lo + inet6 ::1/128 scope host + valid_lft forever preferred_lft forever +2: eth0: mtu 1500 qdisc pfifo_fast state UNKNOWN qlen 1000 + link/ether 00:0c:29:6f:e1:58 brd ff:ff:ff:ff:ff:ff + inet 192.168.9.41/24 brd 192.168.9.255 scope global eth0 + inet6 ::20c:29ff:fe6f:e158/64 scope global dynamic + valid_lft 2591667sec preferred_lft 604467sec + inet6 2002:57ae:43fc:0:20c:29ff:fe6f:e158/64 scope global dynamic + valid_lft 2591990sec preferred_lft 604790sec + inet6 fe80::20c:29ff:fe6f:e158/64 scope link + valid_lft forever preferred_lft forever +[root@pcmk-1 ~]# ping -c 1 www.google.com +PING www.l.google.com (74.125.39.99) 56(84) bytes of data. +64 bytes from fx-in-f99.1e100.net (74.125.39.99): icmp_seq=1 ttl=56 time=16.7 ms + +--- www.l.google.com ping statistics --- +1 packets transmitted, 1 received, 0% packet loss, time 20ms +rtt min/avg/max/mdev = 16.713/16.713/16.713/0.000 ms +[root@pcmk-1 ~]# + +

- Security Shortcuts - - To simplify this guide and focus on the aspects directly connected to clustering, we will now disable the machine’s firewall and SELinux installation. Both of these actions create significant security issues and should not be performed on machines that will be exposed to the outside world. - - - Create an Appendix that deals with (at least) re-enabling the firewall. - - - - - -sed -i.bak "s/SELINUX=enforcing/SELINUX=permissive/g" /etc/selinux/config -/sbin/chkconfig --del iptables - - - - - Now reboot all nodes so the new security settings take effect. - - - -

Before You Continue Repeat the Installation steps so that you have 2 Fedora nodes with the cluster software installed. For the purposes of this document, the additional node is called pcmk-2 with address 192.168.122.42.
Setup
Finalize Networking Confirm that you can communicate with the two new nodes:
Verify Connectivity by IP address ping -c 3 192.168.122.102 [root@pcmk-1 ~]# ping -c 3 192.168.122.102 PING 192.168.122.102 (192.168.122.102) 56(84) bytes of data. 64 bytes from 192.168.122.102: icmp_seq=1 ttl=64 time=0.343 ms 64 bytes from 192.168.122.102: icmp_seq=2 ttl=64 time=0.402 ms 64 bytes from 192.168.122.102: icmp_seq=3 ttl=64 time=0.558 ms --- 192.168.122.102 ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2000ms rtt min/avg/max/mdev = 0.343/0.434/0.558/0.092 ms
Now we need to make sure we can communicate with the machines by their name. If you have a DNS server, add additional entries for the three machines. Otherwise, you’ll need to add the machines to /etc/hosts . Below are the entries for my cluster nodes:
Set up /etc/hosts entries grep pcmk /etc/hosts [root@pcmk-1 ~]# grep pcmk /etc/hosts 192.168.122.101 pcmk-1.clusterlabs.org pcmk-1 192.168.122.102 pcmk-2.clusterlabs.org pcmk-2
We can now verify the setup by again using ping:
Verify Connectivity by Hostname ping -c 3 pcmk-2 [root@pcmk-1 ~]# ping -c 3 pcmk-2 PING pcmk-2.clusterlabs.org (192.168.122.101) 56(84) bytes of data. 64 bytes from pcmk-1.clusterlabs.org (192.168.122.101): icmp_seq=1 ttl=64 time=0.164 ms 64 bytes from pcmk-1.clusterlabs.org (192.168.122.101): icmp_seq=2 ttl=64 time=0.475 ms 64 bytes from pcmk-1.clusterlabs.org (192.168.122.101): icmp_seq=3 ttl=64 time=0.186 ms --- pcmk-2.clusterlabs.org ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2001ms rtt min/avg/max/mdev = 0.164/0.275/0.475/0.141 ms
Configure SSH SSH is a convenient and secure way to copy files and perform commands remotely. For the purposes of this guide, we will create a key without a password (using the -N “” option) so that we can perform remote actions without being prompted. NOTE: Unprotected SSH keys, those without a password, are not recommended for servers exposed to the outside world. Create a new key and allow anyone with that key to log in:
Creating and Activating a new SSH Key [root@pcmk-1 ~]# ssh-keygen -t dsa -f ~/.ssh/id_dsa -N "" Generating public/private dsa key pair. Your identification has been saved in /root/.ssh/id_dsa.

Short Node Names During installation, we filled in the machine’s fully qualifier domain name (FQDN) which can be rather long when it appears in cluster logs and status output. See for yourself how the machine identifies itself: [root@pcmk-1 ~]# uname -n pcmk-1.clusterlabs.org [root@pcmk-1 ~]# dnsdomainname clusterlabs.org The output from the second command is fine, but we really don’t need the domain name included in the basic host details. To address this, we need to update /etc/sysconfig/network. This is what it should look like before we start. cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=pcmk-1.clusterlabs.org GATEWAY=192.168.122.1 All we need to do now is strip off the domain name portion, which is stored elsewhere anyway. sed -i.bak 's/\.[a-z].*//g' /etc/sysconfig/network Now confirm the change was successful. The revised file contents should look something like this. [root@pcmk-1 ~]# cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=pcmk-1 GATEWAY=192.168.122.1 However we’re not finished. The machine wont normally see the shortened host name until about it reboots, but we can force it to update [root@pcmk-1 ~]# source /etc/sysconfig/network [root@pcmk-1 ~]# hostname $HOSTNAME Now check the machine is using the correct names [root@pcmk-1 ~]# uname -n pcmk-1 [root@pcmk-1 ~]# dnsdomainname clusterlabs.org Now repeat on pcmk-2.
Configuring Corosync Choose a port number and multi-cast http://en.wikipedia.org/wiki/Multicast address. http://en.wikipedia.org/wiki/Multicast_address Be sure that the values you chose do not conflict with any existing clusters you might have. For advice on choosing a multi-cast address, see http://www.29west.com/docs/THPM/multicast-address-assignment.html For this document, I have chosen port 4000 and used 226.94.1.1 as the multi-cast address. export ais_port=4000 export ais_mcast=226.94.1.1 Next we automatically determine the hosts address. By not using the full address, we make the configuration suitable to be copied to other nodes. export ais_addr=`ip addr | grep "inet " | tail -n 1 | awk '{print $4}' | sed s/255/0/` Display and verify the configuration options [root@pcmk-1 ~]# env | grep ais_ ais_mcast=226.94.1.1 ais_port=4000 ais_addr=192.168.122.0 Once you’re happy with the chosen values, update the Corosync configuration cp /etc/corosync/corosync.conf.example /etc/corosync/corosync.conf sed -i.bak "s/.*mcastaddr:.*/mcastaddr:\ $ais_mcast/g" /etc/corosync/corosync.conf sed -i.bak "s/.*mcastport:.*/mcastport:\ $ais_port/g" /etc/corosync/corosync.conf sed -i.bak "s/.*bindnetaddr:.*/bindnetaddr:\ $ais_addr/g" /etc/corosync/corosync.conf Tell Corosync to run as the root user cat <<-END >>/etc/corosync/corosync.conf aisexec { user: root group: root } END Finally, tell Corosync to start Pacemaker cat <<-END >>/etc/corosync/corosync.conf service { # Load the Pacemaker Cluster Resource Manager name: pacemaker ver: 0 } END The final configuration should look something like the sample in the appendix.
Propagate the Configuration Now we need to copy the changes so far to the other node: [root@pcmk-1 ~]# for f in /etc/corosync/corosync.conf /etc/hosts; do scp $f pcmk-2:$f ; done corosync.conf 100% 1528 1.5KB/s 00:00 hosts 100% 281 0.3KB/s 00:00 [root@pcmk-1 ~]#
