docker安装出现"Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?"

今天按照这个教程使用WSL安装docker时遇到了个问题:

• 使用命令:$ docker search mysql

• 出现:Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

进一步测试发现其他命令也都不能使用

必应搜索一番之后找到了一些解决方案:例如这个博客

$ systemctl daemon-reload
$ sudo service docker restart
$ sudo service docker status

不过我在执行第一个命令时就出现了:

System has not been booted with systemd as init system (PID 1). Can't operate

后来找到了这个issue

@craigloewen-msft

"Instead of using sudo systemctl start docker use: sudo /etc/init.d/docker start , as of right now we do not have systemd in WSL 2."

尝试了sudo /etc/init.d/docker start启动docker之后便不再出现片头那个问题
