在创builddaemon.json之后，docker服务不会启动

执行以下步骤时出现以下错误消息

● docker.service - Docker Application Container Engine Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled) Active: failed (Result: exit-code) since Wed 2017-08-30 09:21:52 CEST; 13s ago Docs: https://docs.docker.com Process: 11581 ExecStart=/usr/bin/dockerd -H fd:// (code=exited, status=1/FAILURE) Main PID: 11581 (code=exited, status=1/FAILURE) CPU: 28ms Aug 30 09:21:52 debian systemd[1]: docker.service: Failed with result 'exit-code'.

• 我在VirtualBox上创build了一个新的Ubuntu 64位虚拟机。
• 然后我使用安装脚本来安装docker： https ： //get.docker.com/
• 安装成功后，我尝试将守护程序configuration为10.0.2.15:2375以便将其转发给我的主机操作系统
• 我运行nano /etc/docker/daemon.json来创build文件

• 我粘贴下面的例子

  { "debug": true, "tls": false, "tlscert": "/var/docker/server.pem", "tlskey": "/var/docker/serverkey.pem", "hosts": ["tcp://10.0.2.15:2375"] }

• 然后我跑service docker restart

• 运行service docker status显示我上面的消息
