查一下文件夹目录的权限
# namei -om /home/ubuntu/campo/releases/20150824101227/tmp/cache f: /home/ubuntu/campo/releases/20150824101227/tmp/cache drwxr-xr-x root root / drwxr-xr-x root root home drwxr-xr-x ubuntu ubuntu ubuntu drwxr-xr-x root root campo drwxr-xr-x root root releases drwxr-xr-x root root 20150824101227 drwxr-xr-x root root tmp lrwxrwxrwx root root cache -> /home/ubuntu/campo/shared/tmp/cache drwxr-xr-x root root / drwxr-xr-x root root home drwxr-xr-x ubuntu ubuntu ubuntu drwxr-xr-x root root campo drwxr-xr-x root root shared drwxr-xr-x root root tmp drwxr-xr-x root root cache
网上看了一下没有太好的方法，只能先修改下权限了
# chmod 777 /home/ubuntu/campo/shared/tmp/cache/
