not
quite
the
Orchestra

33. A
way
to
achieve
that…

34. #!/bin/bash -e
for node in $(mco find --np -C roles::node)
do
echo "restarting ssh on $node"
mco service --np sshd restart -I $node >/dev/null
sleep 2
mco rpc service status service=sshd -I $node -j |
grep "status.*running" >/dev/null 2>&1
echo "ssh is up on $node"
done

35. #!/usr/bin/ruby
require 'mcollective'
include MCollective::RPC
util = rpcclient("rpcutil")
util.progress = false
util.class_filter /roles::node/
nodes = []
util.ping.each do |resp|
nodes << resp[:sender]
end
util.disconnect
status = ""
nodes.each do |node|
srv = rpcclient("service")
srv.progress = false
srv.identity_filter node
puts "restarting sshd on #{node}"
srv.restart(:service => "sshd")
srv.reset
i = 0
while i < 3 do
srv.status(:service => "sshd").each do |resp|
status = resp[:data][:status]
