使用Capistrano进行Rails应用部署杀死资产预编译

Question

上限部署：冷滚上限部署，触发错误

[out :: xxx.xxx.xxx.xxx] Killed

我已经尝试了很多建议，但是对我来说很实用。

我的deploy.rb

deploy.rb：

require "bundler/capistrano" 

server "xxx.xxx.xxx.xxx", :web, :app, :db, primary: true

set :application, "app" 
set :user, "user" 
set :deploy_to, "/home/#{user}/apps/#{application}" 
set :deploy_via, :remote_cache 
set :use_sudo, false

set :scm, "git" 
set :repository, "git@github.com:git_user/#{application}.git" 
set :branch, "master"

default_run_options[:pty] = true 
ssh_options[:forward_agent] = true


after "deploy", "deploy:cleanup" # keep only the last 5 releases

namespace :deploy do 

%w[start stop restart].each do |command|
    desc "#{command} unicorn server" 
    task command, roles: :app, except: {no_release: true} do
        run "/etc/init.d/unicorn_#{application} #{command}" 
    end
end

task :setup_config, roles: :app do 
    sudo "ln -nfs #{current_path}/config/nginx.conf /etc/nginx/sites-enabled/#{application}" 
    sudo "ln -nfs #{current_path}/config/unicorn_init.sh /etc/init.d/unicorn_#{application}" 
    run "mkdir -p #{shared_path}/config" 
    put File.read("config/database.example.yml"), "#{shared_path}/config/database.yml" 
    puts "Now edit the config files in #{shared_path}."
end
after "deploy:setup", "deploy:setup_config"

task :symlink_config, roles: :app do 
    run "ln -nfs #{shared_path}/config/database.yml #{release_path}/config/database.yml"
end
after "deploy:finalize_update", "deploy:symlink_config"
desc "Make sure local git is in sync with remote." 
task :check_revision, roles: :web do
    unless `git rev-parse HEAD` == `git rev-parse origin/master` 
        puts "WARNING: HEAD is not the same as origin/master"
        puts "Run `git push` to sync changes." 
        exit
    end 
end 
before "deploy", "deploy:check_revision" 
#rake seed task
desc "Seed the database on already deployed code"
task :seed, :only => {:primary => true}, :except => { :no_release => true } do
    run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:seed"
end
desc "Seed the database on already deployed code"
task :drop, :only => {:primary => true}, :except => { :no_release => true } do
    run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:drop:all"
    run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:create:all"
    run "cd #{current_path}; RAILS_ENV=#{rails_env} bundle exec rake db:migrate"
end
end

在我的production.rb中

config.assets.compress = true

和我的文件

load 'deploy'
# Uncomment if you are using Rails' asset pipeline
load 'deploy/assets'
Dir['vendor/gems/*/recipes/*.rb','vendor/plugins/*/recipes/*.rb'].each { |plugin| load(plugin) } 
load 'config/deploy' # remove this line to skip loading any of the default tasks

执行带有“捆绑执行耙资产：precompile RAILS_ENV = production --trace”的本地预编译，不会出现任何错误。

我的错误在哪里？ 热调试吗？ 还是某个地方有一些capistano日志文件，可以在其中查找更多详细信息？

Answer 1

我自己找到答案

从capfile中删除“加载'deploy / assets'”，然后运行

cap deploy:cold

这将正常工作，但仅在初始部署时有效。 然后像往常一样在服务器上“ sudo服务nginx重新启动”，并添加回已删除的代码段。

And BAMM!! It works :)

Answer 2

听起来它使您用光了内存，这个问题和答案帮助了我-我增加了数字海洋服务器上的交换，并且一切正常： 在capistrano失败的情况下进行部署

Answer 3

对于面临相同问题且Andrey回答不起作用的任何人，请停止服务器“ sudo service nginx stop”，然后进行帽部署，然后再次启动服务器“ sudo service nginx start”。 它为我工作。
