Rails - capistrano和chmod

Question

我想通過capistrano使用chmod來爲文件夾添加權限。例如，我想這樣做：

chmod 777 -R /vol/www/apps/ror_tutorial/current/log/ 

所以，我想通過capistrano的任務來做到這一點。我試過：

desc "Fix permission" 
    task :fix_permissions, :roles => [ :app, :db, :web ] do 
    run "#{try_sudo} chmod 777 -R #{current_path}/log" 
    end 

    after "deploy:update_code", :fix_permissions 

但它不起作用。該文件夾的權限是一樣的：

$ ls -alh /vol/www/apps/ror_tutorial/current/log/ 
total 1008K 
drwxrwxrwx 2 root root 4.0K 2012-02-03 20:22 . 
drwxrwxr-x 7 root root 4.0K 2012-01-25 20:50 .. 
-rwxrwxrwx 1 root root 419K 2012-02-03 14:35 development.log 
-rwxrwxrwx 1 root root 530K 2012-02-03 20:16 production.log 
-rwxrwxrwx 1 root root 0 2012-02-02 14:21 searchd.development.pid 
-rwxrwxrwx 1 root root 15K 2012-02-03 20:22 searchd.log 
-rw------- 1 root root 6 2012-02-03 20:22 searchd.production.pid 
-rwxrwxrwx 1 root root 19K 2012-02-03 18:07 searchd.query.log 

如果我嘗試打印文件模式通過ssh手動它的工作原理：

$ chmod 777 -R /vol/www/apps/ror_tutorial/current/log/ 
$ ls -alh /vol/www/apps/ror_tutorial/current/log/ 
total 1008K 
drwxrwxrwx 2 root root 4.0K 2012-02-03 20:22 . 
drwxrwxr-x 7 root root 4.0K 2012-01-25 20:50 .. 
-rwxrwxrwx 1 root root 419K 2012-02-03 14:35 development.log 
-rwxrwxrwx 1 root root 530K 2012-02-03 20:16 production.log 
-rwxrwxrwx 1 root root 0 2012-02-02 14:21 searchd.development.pid 
-rwxrwxrwx 1 root root 15K 2012-02-03 20:22 searchd.log 
-rwxrwxrwx 1 root root 6 2012-02-03 20:22 searchd.production.pid 
-rwxrwxrwx 1 root root 19K 2012-02-03 18:07 searchd.query.log 

我怎麼能寫Capistrano的正確的任務做到這一點？

Answer 1

嘗試更改掛鉤後部署：符號鏈接，我認爲您正在更新'以前'當前目錄中的權限。注意：部署：symlink將很快更改爲部署：create_symlink，如果在將Capistrano升級到2.10或更高版本後發生故障，請記住這一點。
