Subsys lock problem with CentOS 6.2 and Apache

Fabric tutorial 2 – File transfer & error handling

On the first turorial we learned to run commands on remote hosts with Fabric. Now we move on to
transfering files. Transfering new configuration files is usually quite important part of system administration.
Also retrieving log files from the remote machines might be useful.

Sending files

Let’s assume we’ve made a new ssh_config file with important changes and we want to send it to our
remote hosts. Here’s a task for sending files.

def file_send(localpath,remotepath):

Run it with:
fab file_send:path/to/edited/ssh_config,/etc/ssh/ssh_config
or if the modified ssh_config is in the directory where you’re running Fabric:
fab file_send:ssh_config,/etc/ssh/ssh_config

If we’re sending the file to a location that doesn’t need sudo eg. /tmp/, we don’t need the use_sudo=True.
