为什么我的capistrano失败了？

Question

行，所以我有一个新的EC2实例，它是所有设置和我ssh与用户EC2用户和我的本地机器上，我跑了检查命令

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 

所有似乎确定那里，但是当我这样做帽部署在结尾

[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/2012/var/www/projects/current'" on 50.19.84.170 

然后我看看是否有什么在版本目录中并没有什么

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 .. 

不知道我在做什么WR得到这个错误翁...这里是我的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 

什么，我需要改变

这里是目录

任何想法

ls -la /var/www/projects/shared/ 
total 20 
drwxrwxr-x 5 apache webshare 4096 Jan 23 13:32 . 
drwxrwxr-x 5 apache webshare 4096 Jan 20 03:03 .. 
drwxrwxr-x 2 apache webshare 4096 Jan 20 03:31 log 
drwxrwxr-x 2 apache webshare 4096 Jan 23 13:32 pids 
drwxrwxr-x 2 apache webshare 4096 Jan 23 13:32 system 

Answer 1

所以，从输出你可以看到：

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

Mkdir那些失踪的dirs，并确保他们的权限是确定的。
