RSH configuration (each machine in the cluster does the following)

1. Since SUSE LINUX does not come with the RSH-SERVER service, you first need to download the RPM package of the rsh-server service from www.rpmfind.net.

Then switch to the ROOT user to install the corresponding file rpm-ivh rsh-server-0.17-15mdk.x86_64.rpm

two。 Configure / etc/hosts to confirm that each machine in the cluster has three identical files / etc/hosts / etc/hosts.equiv / root/.rhosts

3. Edit / etc/securetty file to add three rsh rexec rlogin services

4. Edit / etc/xinetd.d/rexec, rlogin, rsh. Change "disable = YES" to "disable = NO", which needs to be removed or commented out.

5. Restart the service service xinetd restart

6. After the service is restarted successfully, test the RSH NODEX and enter.

7. Configure a mutual trust relationship

First, execute the following command on two nodes

Mkdir / .ssh

Chmod 700. ssh

Ssh-keygen-t rsa

Ssh-keygen-t dsa

Then, execute the following command on the node dbtest1

Cat ~ / .ssh/id_rsa.pub > > ~ / .ssh/authorized_keys

Cat ~ / .ssh/id_dsa.pub > > ~ / .ssh/authorized_keys

Ssh dbtest2 cat ~ / .ssh/id_rsa.pub > > ~ / .ssh/authorized_keys
