  • Install the RSH service on all nodes

1.1 install RSH on node01

[Root @ db2-node01 ~] # Rpm-qa | grep-I rsh-server
[Root @ db2-node01 ~] # Yum install rsh-server
[Root @ db2-node01 ~] # Chkconfig xinetd on
[Root @ db2-node01 ~] # Chkconfig rsh on
[Root @ db2-node01 ~] # Chkconfig rlogin on
[Root @ db2-node01 ~] #/Etc/init. d/xinetd restart

1.2 set remote access to RSH
[Root @ db2-node01 ~] # Vi/root/. rhosts
Db2-node01 root
Db2-node02 root

1.3 modify rsh in kerberos

[Root @ db2-node01 ~] # Cd/usr/kerberos/bin
[Root @ db2-node01 ~] # Mv rsh. sav
[Root @ db2-node01 ~] # Ln-s/usr/bin/rsh
[Root @ db2-node01 ~] #/Etc/init. d/xinetd restart
[Root @ db2-node01 ~] # Ls-al/usr/bin/rsh

1.4 add rsh to the/etc/securetty File

[Root @ db2-node01 ~] # Echo rsh>/etc/securetty

1.5 Add a DB2 instance user RSH
[Root @ db2-node01 ~] # Vi/home/db2inst2/. rhosts
Db2-node01 root
Db2-node02 root

1.6 Test
[Root @ db2-node01 ~] # Rsh db2-node01 ls
[Root @ db2-node01 ~] # Rsh db2-node02 ls


2.1 install RSH on node02

[Root @ db2-node02 ~] # Rpm-qa | grep-I rsh-server
[Root @ db2-node02 ~] # Yum install rsh-server
[Root @ db2-node02 ~] # Chkconfig xinetd on
[Root @ db2-node02 ~] # Chkconfig rsh on
[Root @ db2-node02 ~] # Chkconfig rlogin on
[Root @ db2-node02 ~] #/Etc/init. d/xinetd restart

2.2 set remote access to RSH
[Root @ db2-node02 ~] # Vi/root/. rhosts
Db2-node01 root
Db2-node02 root

2.3 modify rsh in kerberos

[Root @ db2-node01 ~] # Cd/usr/kerberos/bin
[Root @ db2-node01 ~] # Mv rsh. sav
[Root @ db2-node01 ~] # Ln-s/usr/bin/rsh
[Root @ db2-node01 ~] #/Etc/init. d/xinetd restart
[Root @ db2-node01 ~] # Ls-al/usr/bin/rsh

2.4 Add rsh to the/etc/securetty File

[Root @ db2-node01 ~] # Echo rsh>/etc/securetty


2.5 Add a DB2 instance user RSH
[Root @ db2-node01 ~] # Vi/home/db2inst2/. rhosts
Db2-node01 root
Db2-node02 root

2.6 Test
[Root @ db2-node01 ~] # Rsh db2-node01 ls
[Root @ db2-node01 ~] # Rsh db2-node02 ls

Initialize RSCT cluster nodes
The following actions are performed by the root user on the db2-node01 and db2-node01
[Root @ db2-node01 ~] # Preprpnode db2-node01 db2-node02
[Root @ db2-node02 ~] # Preprpnode db2-node01 db2-node02

  • Disable all node firewalls and selinux
[Root @ db2-node01 ~] #/Etc/init. d/iptables stop
[Root @ db2-node02 ~] #/Etc/init. d/iptables stop
