这个目录下面都是一些该容器的配置信息,编辑 hostconfig.json

{"Binds":["/etc/localtime:/etc/localtime:ro","/etc/timezone:/etc/timezone:ro","/mnt/docker-data/logstash/y-activity:/usr/src/app/logs:rw"],"ContainerIDFile":"","LogConfig":{"Type":"json-file","Config":{}},"NetworkMode":"default","PortBindings":{"3909/tcp":[{"HostIp":"10.170.48.177","HostPort":"3909"}]},"RestartPolicy":{"Name":"","MaximumRetryCount":0},"AutoRemove":false,"VolumeDriver":"","VolumesFrom":[],"CapAdd":null,"CapDrop":null,"Dns":[],"DnsOptions":[],"DnsSearch":[],"ExtraHosts":null,"GroupAdd":null,"IpcMode":"","Cgroup":"","Links":["common_nginx2_1:nginxProxy"],"OomScoreAdj":0,"PidMode":"","Privileged":false,"PublishAllPorts":false,"ReadonlyRootfs":false,"SecurityOpt":null,"UTSMode":"","UsernsMode":"","ShmSize":67108864,"Runtime":"runc","ConsoleSize":[0,0],"Isolation":"","CpuShares":0,"Memory":0,"NanoCpus":0,"CgroupParent":"","BlkioWeight":0,"BlkioWeightDevice":null,"BlkioDeviceReadBps":null,"BlkioDeviceWriteBps":null,"BlkioDeviceReadIOps":null,"BlkioDeviceWriteIOps":null,"CpuPeriod":0,"CpuQuota":0,"CpuRealtimePeriod":0,"CpuRealtimeRuntime":0,"CpusetCpus":"","CpusetMems":"","Devices":null,"DeviceCgroupRules":null,"DiskQuota":0,"KernelMemory":0,"MemoryReservation":0,"MemorySwap":0,"MemorySwappiness":-1,"OomKillDisable":false,"PidsLimit":0,"Ulimits":null,"CpuCount":0,"CpuPercent":0,"IOMaximumIOps":0,"IOMaximumBandwidth":0}

删除相应的IP和端口号，然后重新 docker start mongo

如果最后还不能解决，只有一个办法，service docker stop
