Ruby on rails 使用Ansible和Capistrano部署

我通过Ansible为Ubuntu服务器14.04 LTS（HVM）创建了用户

deploy

，并希望通过capistrano部署我的应用程序。如果我以用户身份连接ubuntu，则会出现以下错误：

mkdir stderr: mkdir: cannot create directory '/home/deploy/applications/app/releases': Permission denied

INFO [da36e5d8] Running /usr/bin/env mkdir -p /tmp// as deploy@11.111.1.111

Please login as the user "ubuntu" rather than the user "root".

但当我试图运行

cap production deploy

时，会不断出现以下错误：

mkdir stderr: mkdir: cannot create directory '/home/deploy/applications/app/releases': Permission denied

INFO [da36e5d8] Running /usr/bin/env mkdir -p /tmp// as deploy@11.111.1.111

UPD:我在DO（digitalocean.com）上发布了相同的代码，它可以正常工作。但在EC2上它不起作用

sudo mkdir -p /home/deploy/applications
sudo mkdir -p /home/deploy/applications/app/
sudo chown deploy:deploy /home/deploy/applications/app/ # `chown` will change the owner ship so that `User` user can `**Read/Write**` 
umask 0002
mkdir /home/deploy/applications/app/releases ## these are convention 
mkdir /home/deploy/applications/app/shared ## these are convention 
sudo chown deploy:deploy /home/deploy/applications/app/releases
sudo chown deploy:deploy /home/deploy/applications/app/shared

希望这对你有帮助
