[英]Puma .state file
I'm attempting to deploy my rails application w/ puma using Capistrano. 我正在尝试使用Capistrano部署我的rails应用程序w / puma。 Towards the end ofthe deployment it attempts to run 在部署结束时,它会尝试运行
bundle exec pumactl -S /home/deployer/production/shared/sockets/puma.state restart
which fails w/ 失败w /
undefined method `has_key?' for false:FalseClass.
I have simply created a empty file for puma.state
. 我只是为puma.state
创建了一个空文件。 My question is what exactly is this file and what is supposed to be in it? 我的问题是这个文件到底是什么以及它应该是什么?
Puma has a state file that records the PID of the process. Puma有一个状态文件,记录进程的PID。 If you are deploying for the first time, you should delete the .state file, and do a 如果您是第一次部署,则应删除.state文件,然后执行
cap deploy:cold
or, you can start puma manually using something like 或者,您可以使用类似的东西手动启动美洲狮
cap puma:start
This will start the process and create a valid state file. 这将启动该过程并创建一个有效的状态文件。 Here is my puma start command in capistrano: 这是我在capistrano的puma start命令:
namespace :puma do
desc "Start the application"
task :start, :roles => :app, :except => { :no_release => true } do
run "cd #{current_path} && RAILS_ENV=#{rails_env} bundle exec puma -t 8:32 -b 'unix://#{shared_path}/sockets/puma.sock' -S #{shared_path}/sockets/puma.state --control 'unix://#{shared_path}/sockets/pumactl.sock' >> #{shared_path}/log/puma-#{rails_env}.log 2>&1 &", :pty => false
end
after "deploy:start", "puma:start"
end
