FATA[0000] Cannot connect to the Docker daemon. Is 'docker -d' running on this host"color: #ff0000">二、解决方法

以及类似的错误,就连docker version命令都报错了,楼主开始找啊找,找到了好多东西,结果发现没一个能行的,最后楼主使用这样的命令:




# vim /etc/default/docker 


在该文件中添加如下内容:




DOCKER_OPTS="-H unix:///var/run/docker.sock -H 0.0.0.0:5555" 




# service docker restart 


这样就行了..我也不知道怎么样就行了.真的好神奇.


楼主赶快使用了一下




syx@syx-VB:~$ docker version 
Client version: 1.6.2 
Client API version: 1.18 
Go version (client): go1.3.3 
Git commit (client): 7c8fca2 
OS/Arch (client): linux/amd64 
Server version: 1.6.2 
Server API version: 1.18 
Go version (server): go1.3.3 
Git commit (server): 7c8fca2 
OS/Arch (server): linux/amd64 


好神奇,终于可以了,楼主赶快把docker升级到最新版本.




$ sudo add-apt-repository ppa:docker-maint/testing 
$ sudo apt-get update 
$ sudo apt-get install docker.io 


楼主这样就行了一次,然后就又不行了楼主开始找原因,这次楼主问了问别了,别人说在ubuntu下安装一个devicemapper


楼主使用的命令如下:




root@syx-VB:~# apt-get install -y libdevmapper-dev 


还是不行啊


root@syx-VB:~# service docker restart  
root@syx-VB:~# docker version  
root@syx-VB:~# docker version 
Client version: 1.7.0-dev 
Client API version: 1.19 
Go version (client): go1.4.2 
Git commit (client): 9234460 
OS/Arch (client): linux/amd64 
FATA[0000] Get http:///var/run/docker.sock/v1.19/version: read unix /var/run/docker.sock: connection reset by peer. Are you trying to connect to a TLS-enabled daemon without TLS"htmlcode">

root@syx-VB:~# docker -d 
INFO[0000] Listening for HTTP on unix (/var/run/docker.sock) 
FATA[0000] Error starting daemon: error initializing graphdriver: "/var/lib/docker" contains other graphdrivers: devicemapper; Please cleanup or explicitly choose storage driver (-s <DRIVER>) 


看不懂,接着问大神!!!

大神说了把/var/lib/docker下的devicemapper清掉,楼主一看:




root@syx-VB:/var/lib/docker# ls 
aufs containers devicemapper graph init linkgraph.db repositories-aufs repositories-devicemapper tmp trust volumes 


还真有这个目录,于是使用:




root@syx-VB:/var/lib/docker# rm -r devicemapper/ 


接着:




root@syx-VB:/var/lib/docker# docker version 
Client version: 1.7.0-dev 
Client API version: 1.19 
Go version (client): go1.4.2 
Git commit (client): 9234460

root@syx-VB:/var/lib/docker# service docker restart 
root@syx-VB:/var/lib/docker# docker version
