我拥有一个使用 Unicorn 作为 Web 服务器的 Rails 应用程序。
我通过 Capistrano 部署它。
这是我的deploy.rb
文件:
require "bundler/capistrano"
server "91.121.11.100", :web, :app, :db, primary: true
set :application, "myapp"
set :user, "deployer"
set :deploy_to, "/home/#{user}/apps/#{application}"
#set :deploy_via, :remote_cache
set :use_sudo, false
set :scm, "git"
set :repository, "git@github.com:therepository/#{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.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"
end
部署顺利,服务器上的当前文件夹包含预期的更新文件。
但是,发生了一些我不明白的非常奇怪的事情:
我在我的过程开始时有这条线:
logger = Logger.new "#{Rails.root}/log/web_agents.log"
并且仍然出现此错误:
No such file or directory - /home/deployer/apps/myapp/releases/20120612122610/log/web_agents.log
为什么是20120612122610???这是一个旧版本,我什至删除了。
Unicorn 为什么不指向最后一个版本?
为了测试,我什至将 Rails.root 替换为当前路径的硬编码路径。
仍然有同样的错误......我已经杀死,停止,强制停止独角兽......没关系......
任何的想法 ?
我确切地说,我确定该进程是使用“当前”文件夹中的最后更新文件启动的,因为当我删除一个时,进程无法工作并且出现许多错误。
更新
这是我的config/unicorn.rb
文件:
root = "/home/deployer/apps/myapp/current"
working_directory root
pid "#{root}/tmp/pids/unicorn.pid"
stderr_path "#{root}/log/unicorn.log"
stdout_path "#{root}/log/unicorn.log"
listen "/tmp/unicorn.myapp.sock"
worker_processes 2
timeout 30
