Algunas veces tienes que trabajar con la interfaz en l\u00ednea de comandos del OVM Manager, por ejemplo para lanzar varios comandos a la vez, y es un poco tedioso tener que estar poniendo siempre la password:<\/p>\n
[root@ovmmanager1 ~]# ssh -l admin localhost -p 10000\r\nadmin@localhost's password:\r\nOVM><\/pre>\n<\/p>\n
Aqu\u00ed dejo una manera un tanto ortodoxa de configurar su acceso sin introducir una password:<\/p>\n
1) ssh<\/p>\n
[root@ovmmanager1 ~]# ssh-keygen -t rsa -f ~\/.ssh\/admin\r\nGenerating public\/private rsa key pair.\r\nCreated directory '\/root\/.ssh'.\r\nEnter passphrase (empty for no passphrase):\r\nEnter same passphrase again:\r\nYour identification has been saved in \/root\/.ssh\/admin.\r\nYour public key has been saved in \/root\/.ssh\/admin.pub.\r\nThe key fingerprint is:\r\nSHA256:MTxnKUOehUqMlXfTRpj3Jy7SLRoszH\/EmcIWgk5J\/jo root@ovmmanager1\r\nThe key's randomart image is:\r\n+---[RSA 2048]----+\r\n| +.....=. |\r\n| . =+oo=.+ |\r\n| + =X.++ . |\r\n| * .O. o .|\r\n| o +S+ + = o |\r\n| . = B O o |\r\n| . + * o |\r\n| E o . |\r\n| . . |\r\n+----[SHA256]-----+\r\n\r\n[root@ovmmanager1 ~]# cat \/root\/.ssh\/admin.pub > \/home\/oracle\/.ssh\/ovmcli_authorized_keys\r\n\r\n[root@ovmmanager1 ~]# eval `ssh-agent`\r\nAgent pid 865\r\n\r\n[root@ovmmanager1 ~]# ssh-add ~\/.ssh\/admin\r\nIdentity added: \/root\/.ssh\/admin (\/root\/.ssh\/admin)\r\n\r\n[root@ovmmanager1 ~]# ssh admin@ovmmanager1 -p 10000\r\nThe authenticity of host '[ovmmanager1]:10000 ([192.168.115.40]:10000)' can't be established.\r\nRSA key fingerprint is SHA256:3rw6ji5BCr3PeAcsKStsk8GrNU8mVaqGiC3dc\/rSxC0.\r\nRSA key fingerprint is MD5:f1:0b:f7:8f:39:e5:75:a4:e0:6e:a2:59:d8:fc:d5:32.\r\nAre you sure you want to continue connecting (yes\/no)? yes\r\nWarning: Permanently added '[ovmmanager1]:10000,[192.168.115.40]:10000' (RSA) to the list of known hosts.\r\nOVM>\r\n\r\n<\/pre>\n<\/p>\n
2) script<\/p>\n
[root@ovmmanager1 ~]# cat ovmcli.sh\r\n#!\/bin\/bash\r\neval `ssh-agent` >> \/dev\/null 2>&1\r\nssh-add ~\/.ssh\/admin >> \/dev\/null 2>&1\r\nexport ovmUser=admin\r\nexport adminServer=ovmmanager1\r\nOVMCLI=\"ssh -o ServerAliveInterval=40 $ovmUser@$adminServer -p 10000\"\r\n\r\n$OVMCLI $@\r\nssh-agent -k >> \/dev\/null 2>&1\r\n<\/pre>\n<\/p>\n
Una de las partes m\u00e1s importantes del script, es el \u00faltimo comando (que elimina el proceso ‘ssh-agent’ que hemos abierto), pues sin \u00e9l, se ir\u00edan acumulando los procesos ‘ssh-agent’ en el sistema operativo, ralentizando el mismo.<\/p>\n
<\/p>\n
3) permisos<\/p>\n
[root@ovmmanager1 ~]# chmod 700 ovmcli.sh<\/pre>\n<\/p>\n
4) alias<\/p>\n
alias ovmcli='\/root\/.\/ovmcli.sh'<\/pre>\n<\/p>\n
El alias lo puedes a\u00f1adir al final del fichero .bashrc en el $HOME del usuario.<\/p>\n
<\/p>\n
Su ejecuci\u00f3n dar\u00eda este resultado:<\/p>\n
[root@ovmmanager1 ~]# ovmcli\r\nOVM><\/pre>\n<\/p>\n
Tambi\u00e9n nos permite pasarle comandos directamente desde el prompt del SO:<\/p>\n
[root@ovmmanager1 ~]# ovmcli list server\r\nOVM> list server\r\nCommand: list server\r\nStatus: Success\r\nTime: 2019-01-08 22:32:38,899 CET\r\nData:\r\nid:37:38:36:38:33:30:5a:43:32:38:33:38:30:31:32:33 name:ovmsrv02\r\nid:37:38:36:38:33:30:5a:43:32:38:33:38:30:31:32:32 name:ovmsrv01\r\nOVM> Connection closed.\r\n<\/pre>\n<\/p>\n
Si quieres configurarlo para el usuario ‘oracle’ sigue los mismos pasos \ud83d\ude42<\/p>\n
