AIX 7安装11.2.0.4 RAC-（主机名大写坑）

在我们安装Oracle RAC的时候，要求操作系统的主机名都要小写，8个字符以内，不要使用下划线，不然我们在配置互信验证的时候是无法通过的，在配置EMCC的时候也可能有问题。

AIX + 11G RAC 手动配置互信

After the script is executed, the user can use SSH to runcommands on the remote hosts or copy files between this host test1aand 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 copyfiles between the local host and the remote hosts.

IF THE SETUP IS CORRECTLY SETUP,THERE SHOULD BE NO OUTPUT OTHER THAN THE DATE AND SSH SHOULD NOT ASK FORPASSWORDS. If you see any output other than date or are prompted for thepassword, ssh is not setup correctly and you will need to resolve theissue 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 sshfor 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 The client public key on the server may be outdated.4.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 ormay 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 theadditional text to the /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.
