role :app, "#{ipaddr}" role :web, "#{ipaddr}"
最后，执行
hadoop@rubypc:~/src/jshop$ cap -vT

求助，哪里错了？
deploy.rb 一般应该是这样的语法吧？
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
# Your restart mechanism here, for example:
execute :touch, release_path.join('tmp/restart.txt')
execute :curl, '-s -D - apc.sandisk.com -o /dev/null'
end
end
after :publishing, :restart
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end
end
