AIX 7安装11.2.0.4 RAC-（主机名大写坑）

分别在grid用户和oracle用户下执行 $ ./sshsetup/sshUserSetup.sh -user grid -hosts "test1a test1b" -advanced -noPromptPassphrase The output of this script is also logged into /tmp/sshUserSetup_2018-03-20-22-42-12.log Hosts are test1a test1b user is grid Platform:- AIX Checking if the remote hosts are reachable PING test1a: (20.1.1.3): 56 data bytes 64 bytes from 20.1.1.3: icmp_seq=0 ttl=255 time=0 ms 64 bytes from 20.1.1.3: icmp_seq=1 ttl=255 time=0 ms 64 bytes from 20.1.1.3: icmp_seq=2 ttl=255 time=0 ms 64 bytes from 20.1.1.3: icmp_seq=3 ttl=255 time=0 ms 64 bytes from 20.1.1.3: icmp_seq=4 ttl=255 time=0 ms --- test1a ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 0/0/0 ms PING test1b: (20.1.1.4): 56 data bytes 64 bytes from 20.1.1.4: icmp_seq=0 ttl=255 time=0 ms 64 bytes from 20.1.1.4: icmp_seq=1 ttl=255 time=0 ms 64 bytes from 20.1.1.4: icmp_seq=2 ttl=255 time=0 ms 64 bytes from 20.1.1.4: icmp_seq=3 ttl=255 time=0 ms 64 bytes from 20.1.1.4: icmp_seq=4 ttl=255 time=0 ms --- test1b ping statistics --- 5 packets transmitted, 5 packets received, 0% packet loss round-trip min/avg/max = 0/0/0 ms Remote host reachability check succeeded. The following hosts are reachable: test1a test1b. The following hosts are not reachable: . All hosts are reachable. Proceeding further... firsthost test1a numhosts 2 The script will setup SSH connectivity from the host test1a to all the remote hosts. After the script is executed, the user can use SSH to run commands on the remote hosts or copy files between this host test1a and the remote hosts without being prompted for passwords or confirmations. NOTE 1: As part of the setup procedure, this script will use ssh and scp to copy files between the local host and the remote hosts. Since the script does not store passwords, you may be prompted for the passwords during the execution of the script whenever ssh or scp is invoked. NOTE 2: AS PER SSH REQUIREMENTS, THIS SCRIPT WILL SECURE THE USER HOME DIRECTORY AND THE .ssh DIRECTORY BY REVOKING GROUP AND WORLD WRITE PRIVILEDGES TO THESE directories. Do you want to continue and let the script make the above mentioned changes (yes/no)? yes The user chose yes User chose to skip passphrase related questions. Creating .ssh directory on local host, if not present already Creating authorized_keys file on local host Changing permissions on authorized_keys to 644 on local host Creating known_hosts file on local host Changing permissions on known_hosts to 644 on local host Creating config file on local host If a config file exists already at /home/grid/.ssh/config, it would be backed up to /home/grid/.ssh/config.backup.

SSH setup is complete. ------------------------------------------------------------------------ Verifying SSH setup =================== The script will now run the date command on the remote nodes using ssh to verify if ssh is setup correctly. IF THE SETUP IS CORRECTLY SETUP, THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FOR PASSWORDS. If you see any output other than date or are prompted for the password, ssh is not setup correctly and you will need to resolve the issue and set up ssh again. The possible causes for failure could be: 1. The server settings in /etc/ssh/sshd_config file do not allow ssh for user grid. 2. The server may have disabled public key based authentication. 3. The client public key on the server may be outdated. 4. /home/grid or /home/grid/.ssh on the remote host may not be owned by grid. 5. User may not have passed -shared option for shared remote users or may be passing the -shared option for non-shared remote users. 6. If there is output in addition to the date, but no password is asked, it may be a security alert shown as part of company policy. Append the additional text to the <OMS HOME>/sysman/prov/resources/ignoreMessages.txt file. ------------------------------------------------------------------------ --test1a:-- Running /usr/bin/ssh -x -l grid test1a date to verify SSH connectivity has been setup from local host to test1a. IF YOU SEE ANY OTHER OUTPUT BESIDES THE OUTPUT OF THE DATE COMMAND OR IF YOU ARE PROMPTED FOR A PASSWORD HERE, IT MEANS SSH SETUP HAS NOT BEEN SUCCESSFUL. Please note that being prompted for a passphrase may be OK but being prompted for a password is ERROR.
