Вот вывод из Capistrano:
02:05 sidekiq:start
01 sudo service sidekiq start index=1
01 sidekiq (1) start/running, process 26392
✔ 01 deployer@IP 0.721s
02 sudo service sidekiq start index=2
02 sidekiq (2) start/running, process 26505
✔ 02 deployer@IP 0.728s
После входа на сервер и ps aux | grep sidekiq процесс не выполняется. Поэтому я go возвращаюсь на вкладку локального терминала и запускаю
cap staging sidekiq:start
, и новый процесс Sidekiq появляется на сервере в течение нескольких секунд:
ps aux | grep sidekiq
deployer 489 52.0 1.0 76344 40856 ? Rs 13:13 0:00 /home/deployer/.rvm/rubies/ruby-2.6.3/bin/ruby /home/deployer/.rvm/gems/ruby-2.6.3/bin/bundle exec sidekiq -i 1 -e staging
deployer 695 0.0 0.0 10472 936 pts/0 S+ 13:13 0:00 grep --color=auto sidekiq
deployer 32744 42.2 1.4 111100 56188 ? Rs 13:13 0:02 /home/deployer/apps/app-staging/shared/bundle/ruby/2.6.0/bin/sidekiq -i 2 -e staging
Но через несколько секунд он исчезнет.
Если я запускаю с сервера RAILS_ENV=staging bundle exec sidekiq - Sidekiq запущен. Но когда я перезагружаю сервер / развертываю новый код, процесс Sidekiq убивается.
Вот мои грабли для Sidekiq:
namespace :sidekiq do
desc "Tells Sidekiq (with signal TSTP) it will be shutting down at some point in the near future."\
" It will stop accepting new work but continue working on current messages"
task :quiet do
on roles(:app) do
puts capture("pgrep -f 'sidekiq' | xargs kill -TSTP")
end
end
desc "Signals that Sidekiq should shut down within the -t timeout option given at start-up (see config/sidekiq.yml)."\
" It will stop accepting new work, but continue working on current messages (as with USR1)."\
" Any workers that do not finish within the timeout are forcefully terminated"\
" and their messages are pushed back to Redis to be executed again when Sidekiq starts up. "
task :terminate_gracefully do
on roles(:app) do
puts capture("pgrep -f 'sidekiq' | xargs kill -TERM")
end
end
desc "Starts sidekiq workers. Fails if there are already running processes."
task :start do
on roles(:app) do
pids = capture("pgrep -f 'sidekiq'; true")
puts "Present sidekiq process pids #{pids}"
if pids.split("\n").count == 1
# For each worker service with index ID is called
execute "sudo service sidekiq start index=1"
execute "sudo service sidekiq start index=2"
else
puts "##------------------------------------------------------------------##"
puts "Sidekiq was not terminated before start execution. Wait untils it is finished and start it again (or kill the processes)."
puts "##------------------------------------------------------------------##"
end
end
end
task :restart do
invoke "sidekiq:terminate_gracefully"
invoke "sidekiq:start"
end
end
Почему Sidekiq v6 не запускается автоматически Capistrano?
