鉴于docker 安装的方式非常多种类，也鉴于docker发展太快，或多或少会有一些问题暴露，本文就针对Docker 的安装过程中的问题进行收集
1、service docker start/systemctl start docker执行时报这“"systemctl status docker.service" and "journalctl -xe" for details”错误
Job for docker.service failed because the control process exited with error code. See "systemctl status docker.service" and "journalctl -xe" for details.解决方案（针对自己在docker 官网下载最新的rpm 后自己使用yum install **/**/**.rpm 安装出现这个问题）：

Apr 3 15:31:11 Docker systemd: docker.service: main process exited, code=exited, status=1/FAILURE
Apr 3 15:31:11 Docker systemd: Failed to start Docker Application Container Engine.很明显了：mkfs.xfs版本太低，遂更新：
yum update xfsprogs
重启docker服务，正常！
2、docker ps -a /docker images 时报“Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?”
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?解决方案
使用 service docker start / systemctl start docker 启动docker ,如果问题依旧，使用docker version 查看，如果只有客户端docker,那么重启服务尝试。（reboot可以解决很多问题）
服务器重启之后，sudo docker -ps 这个错

之后便可以正常运行 docker 了。记住是服务器（电脑）重启的情况。
3、docker-runc not installed on system（https://blog.csdn.net/qq_33448670/article/details/80058408）
[root@vm173 ~]# cat /etc/docker/daemon.json
{
"log-level":"warn",
"hosts": ["unix:///var/run/docker.sock","tcp://0.0.0.0:2375"],
"runtimes": {
"docker-runc": {
"path": "/usr/libexec/docker/docker-runc-current"
}
},
"add-runtime": "docker-runc=/usr/libexec/docker/docker-runc-current",
"default-runtime": "docker-runc"
}
加入上述配置后重启docker服务4、exec: "docker-proxy": executable file not found in $PATH （https://www.cnblogs.com/cxbhakim/p/9149596.html）
在执行 docker run 操作的时候，一直报如下错误：
[root@etcd1 vagrant]# docker run --name redis-6379 -p 6379:6379 -d --rm daocloud.io/library/redis
9e3e4650004bfd68030ea23c4a1e300556721c516160464afe45554b2184c111
/usr/bin/docker-current: Error response from daemon: driver failed programming external connectivity on endpoint redis-6379 (78ec2496afe55876e51d8e062bb09a6fcda7f36e292b99ad902efc27c65aa555): exec: "docker-proxy": executable file not found in $PATH
可知，启动需要执行 /usr/bin/docker-proxy
查看下 docker-proxy 的位置：
1
2
[root@etcd1 vagrant]# cat /usr/lib/systemd/system/docker.service | grep prox
--userland-proxy-path=/usr/libexec/docker/docker-proxy-current \
创建一条软连接到 /usr/bin/ 下：
1
[root@etcd1 vagrant]# ln -s /usr/libexec/docker/docker-proxy-current /usr/bin/docker-proxy
重新执行操作：
1
2
[root@etcd1 vagrant]# docker run --name redis-6379 -p 6379:6379 -d --rm daocloud.io/library/redis
