CentOS 7 版本

[root@gitserver ~]# uname -r  3.10.0-327.el7.x86_64  [root@gitserver ~]# cat /etc/redhat-release  CentOS Linux release 7.2.1511 (Core)

docker 版本

[root@gitserver /]# docker --version  Docker version 1.12.6, build 3a094bd/1.12.6

修改/etc/sysconfig/docker文件，在最后增加一行DOCKER_OPTS

# docker-latest daemon can be used by starting the docker-latest unitfile.  # To use docker-latest client, uncomment below lines  #DOCKERBINARY=/usr/bin/docker-latest  #DOCKERDBINARY=/usr/bin/dockerd-latest  #DOCKER_CONTAINERD_BINARY=/usr/bin/docker-containerd-latest  #DOCKER_CONTAINERD_SHIM_BINARY=/usr/bin/docker-containerd-shim-latest  DOCKER_OPTS="-H unix:///var/run/docker.sock -H 0.0.0.0:5555"

修改/usr/lib/systemd/system/docker.service

在[Service]的ExexStart=下面增加一行$DOCKER_OPTS

[Service]  Type=notify  NotifyAccess=all  EnvironmentFile=-/etc/sysconfig/docker  EnvironmentFile=-/etc/sysconfig/docker-storage  EnvironmentFile=-/etc/sysconfig/docker-network  Environment=GOTRACEBACK=crash  Environment=DOCKER_HTTP_HOST_COMPAT=1  Environment=PATH=/usr/libexec/docker:/usr/bin:/usr/sbin  ExecStart=/usr/bin/dockerd-current \            --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \            --default-runtime=docker-runc \            --exec-opt native.cgroupdriver=systemd \            --userland-proxy-path=/usr/libexec/docker/docker-proxy-current \            $DOCKER_OPTS \            $OPTIONS \            $DOCKER_STORAGE_OPTIONS \            $DOCKER_NETWORK_OPTIONS \            $ADD_REGISTRY \            $BLOCK_REGISTRY \            $INSECURE_REGISTRY

注意：也可以直接在ExecStart后面追加-H unix:///var/run/docker.sock -H 0.0.0.0:5555，

ExecStart=/usr/bin/dockerd-current \            --add-runtime docker-runc=/usr/libexec/docker/docker-runc-current \            --default-runtime=docker-runc \            --exec-opt native.cgroupdriver=systemd \            --userland-proxy-path=/usr/libexec/docker/docker-proxy-current \            -H unix:///var/run/docker.sock -H 0.0.0.0:5555 \            $OPTIONS \            $DOCKER_STORAGE_OPTIONS \            $DOCKER_NETWORK_OPTIONS \            $ADD_REGISTRY \            $BLOCK_REGISTRY \            $INSECURE_REGISTRY  systemctl dameon

让配置生效：

[root@gitserver system]# systemctl daemon-reload  [root@gitserver system]# systemctl restart docker.service

用netstat查看

[root@gitserver system]# netstat -tnlp |grep 5555  tcp6       0      0 :::5555                 :::*                    LISTEN      2025/dockerd-curren

用curl进行测试

curl 127.0.0.1:5555/info

结果如下：

Debian 8下的配置

配置文件所在的目录与centos不一样

/etc/default/docker/lib/systemd/system/docker.service

如果不知道目录，可以用find命令查找，find / -name ‘docker.service’ -print
