ruby-on-rails - 为什么我的 Capistrano 失败了？

Question

好的，所以我有一个新的 ec2 实例，它已全部设置好，我通过 ssh 与用户 ec2-user 连接，并在我的本地机器上运行了检查命令

cap deploy:check
  * executing `deploy:check'
  * executing "test -d /var/www/projects/releases"
    servers: ["50.19.84.170"]
    [50.19.84.170] executing command
    command finished in 101ms
  * executing "test -w /var/www/projects"
    servers: ["50.19.84.170"]
    [50.19.84.170] executing command
    command finished in 106ms
  * executing "test -w /var/www/projects/releases"
    servers: ["50.19.84.170"]
    [50.19.84.170] executing command
    command finished in 103ms
  * executing "which git"
    servers: ["50.19.84.170"]
    [50.19.84.170] executing command
    command finished in 104ms
You appear to have all necessary dependencies installed

那里一切似乎都很好，但是当我进行 cap deploy 时，我在最后得到了这个错误

 [50.19.84.170] executing command
    command finished in 150ms
failed: "sh -c 'rm -f /var/www/projects/current && ln -s /var/www/projects/releases/20120123133717 /var/www/projects/current'" on 50.19.84.170

然后我查看发布目录中是否有任何内容，但什么都没有

 ls -la /var/www/projects/releases/total 8
drwxrwxr-x 2 ec2-user ec2-user 4096 Jan 23 13:37 .
drwxrwxr-x 5 ec2-user ec2-user 4096 Jan 20 03:03 ..

不确定我做错了什么...这是我的 deploy.rb

set :application, "projects"
set :deploy_to, "/var/www/#{application}"
set :keep_releases, 3

set :scm, :git
set :repository,  "git@github.com:railsdevmatt/fat_free_crm.git"
set :git_shallow_clone, 1
set :branch, "master"
set :use_sudo, true

set :user, "ec2-user"
ssh_options[:forward_agent] = true
default_run_options[:pty] = true

role :app, "50.19.84.170"
role :web, "50.19.84.170"
role :db,  "50.19.84.170", :primary => true

after "deploy:setup", :fix_perms
after "deploy:update_code", :fix_perms

# ssh_options[:keys] = ["#{ENV['HOME']}/Downloads/important.pem"]

task :fix_perms do
  # sudo "chown apache:webshare -R /var/www/projects"
  # sudo "chmod 666 -R /var/www/projects/shared/log/*"
end

任何我需要改变的想法

更新

这是我的全部输出

这是目录

Answer 1

因此，从输出中您可以看到:

chmod: cannot access `/var/www/projects/shared/log/*': No such file or directory

Mkdir 那些丢失的目录并确保它们的权限没问题。
