rhc ssh [No system SSH available] error

问题

I want view my openshift application log in my cmd. I did try :
rhc ssh appname

that time i am getting:

No system SSH available. Please use the --ssh option to specify the path to your SSH executable, or install SSH.

My system have already ssh key.so how can i solve that problem?

回答1:

You need to make sure:

you are in a cmd session where HOME is define (type set HOME to check its value: it must be C:\Users\yourLogin, because ssh needs to look for keys in %HOME%\.ssh)

your ssh.exe parent folder is referenced in the %PATH%, or you can type:

rhc ssh -ssh "c:\prgs\git\PortableGit-2.8.3-64-bit\usr\bin\" -a appname

Replace c:\prgs\git\PortableGit-2.8.3-64-bit with the actual installation path of your Git for Windows.

The easiest solution is to add the git\usr\bin folder (which includes ssh.exe) to the PATH environment variable.

回答2:

If you installed Git for Windows¹, then you can try something similar to:

`rhc ssh --ssh C:\PROGRA~1\Git\usr\bin\ssh.exe -a <appname>`

e.g.

rhc ssh --ssh C:\PROGRA~1\Git\usr\bin\ssh.exe -a myawesomeapp

If you are not interested in adding your git path to PATH you will need to use a 8.3 style path because rhc can't seem to handle spaces in the path.

For x86 versions of git use rhc ssh myapp --ssh C:\Progra~2\Git\usr\bin\ssh.exe
For x64 versions of git use rhc ssh myapp --ssh "C:\Progra~1\Git\usr\bin\ssh.exe

If you leave the spaces like C:\Users\me>rhc ssh myapp --ssh "C:\Program Files (x86)\Git\usr\bin\ssh.exe"

You will get the following error:

Install 'SSH' client like Cygwin.

回答5:

You may want to first got to Openshift Web Console >> Settings and delete the exiting keys. Then run rhc setup in command line. Then try rhc ssh -a yourApp --ssh C:\PROGRA~1\Git\usr\bin\ssh.exe. This is what worked for me so am sharing this answer. Hope this helps. Good Luck.
