Batch exec command on servers & written by golang.

• Exec command on cluster servers.
• Server clusters support.
• Hosts support simple preg(just IPs).
• scp supported(using sftp), can upload file to batch servers(NOTE: supported file only).

Get the package, add the src to workspace path and build it.

But, first you should get golang ssh packages

$ git clone github.com/youngsn/go-ssh
$ go build -o bsh -v -x $GOPATH/go-ssh/src/main.go
$ cp go-ssh/elfgate.yml /etc/
$ sudo cp bsh /usr/local/bin/
$ bsh uptime       # example

Usage:

Execute command just like below, the outputs will print on screen or using > redirect to file.

Now also sudo command are supported, but at first you should enter password if not config pasword.

• -c, config file location, default: /etc/elfgate.yml
• -t, command timeout, default: 0, no timeout
• -g, groups that execute commands, default: default
• enter command directly.

$ bsh -c $CONF -t $TIMEOUT -g $GROUP $CMD

If you want to upload file to batch server, just do like below. Very easy and now only supported file, not directory.

$ bsh -c $CONF -g $GROUP scp $LOCAL_PATH $REMOTE_PATH

username: youngsn        # server username
password:                # login password, if don't config, you will enter through stdin
public_key:              # ssh public authorized key path, if using this, add here

groups:
    default:             # Group default
        - 127.0.0.[1-5]        # simple preg support
        - 127.0.0.[6-7]:233
        - 127.0.0.8            # default port 22
        - 127.0.0.9:25         # port 25
    example:             # Group example
        - 127.0.0.2
        - 127.0.0.3:25
