Docker 安装配置

Centos 6.x 安装

https://dl.fedoraproject.org/pub/epel/6Server/x86_64/docker-io-1.7.1-2.el6.x86_64.rpm

  1. 安装 rpm

    关闭 seLinux

    1
    2
    setenforce 0
    sed -i '/^SELINUX=/c\SELINUX=disabled' /etc/selinux/config

    使用 sohu 源安装

    1
    2
    rpm -ivh https://mirrors.sohu.com/fedora-epel/6/x86_64/epel-release-6-8.noarch.rpm
    sed -i 's/^mirrorlist=https/mirrorlist=http/' /etc/yum.repos.d/epel.repo

    或者使用 fedora-epel 安装

    1
    yum install -y https://dl.fedoraproject.org/pub/epel/6Server/x86_64/epel-release-6-8.noarch.rpm

  2. 安装 docker-io

    1
    yum install -y docker-io

  3. 启动 docker

    1
    service docker start

  4. 修改 docker 默认 IP 段

    docker 启动时默认使用 172.17.x.x 作为容器的 ip 地址

    1
    2
    3
    service docker stop
    ip link set docker0 down
    brctl delbr docker0

    修改/etc/sysconfig/docker 文件 添加-bip 参数

    # Other arguments to pass to the docker daemon process
    # These will be parsed by the sysv initscript and appended
    # to the arguments list passed to docker -d

    other_args=-bip=172.16.10.1/24
    DOCKER_CERT_PATH=/etc/docker

    # Resolves: rhbz#1176302 (docker issue #407)
    DOCKER_NOWARN_KERNEL_VERSION=1

    # Location used for temporary files, such as those created by
    # # docker load and build operations. Default is /var/lib/docker/tmp
    # # Can be overriden by setting the following environment variable.
    # # DOCKER_TMPDIR=/var/tmp

Docker 网络配置

Centos 默认配置文件位置 /etc/sysconfig/docker

docker 默认添加 docker0 网桥
修改 docker0 IP

ifconfig docker0 172.12.10.1 netmask 255.255.255.0 up

ip link set dev docker0 down 停用docker0
ip link set dev docker0 up 启用docker0

brctl delbr docker0 删除docker0(service docker restart 后自动创建)

添加 linux 网桥

service docker restart 重启使用设置生效（使用 br0 网桥）

使用 brctl 命令
查看网桥

[root@localhost hadoop-cluster-docker]# brctl show
bridge name	bridge id		STP enabled	interfaces
br0		8000.82edf9468ced	no		eth0
							veth1pl12684
							veth1pl12880
							veth1pl13068

添加网桥

1
brctl addbr

删除网桥

1
brctl delbr

brctl addif add interface to bridge
brctl delif delete interface from bridge

设置网桥生效

1
ip link set dev br0 up

设置网桥失效

1
ip link set dev docker0 down

ip addr 查看信息

1
ip addr

brctl 创建临时网桥

1
brctl addbr br1

设置网桥地址并生效

1
ifconfig br1 192.168.56.111 netmask 255.255.255.0 up

将网卡设备 eth0 加入网桥

1
brctl addif br1 eth0

pipework 设置 docker 静态 ip

docker 启动指定网络自定

1
docker run --net=none
1
wget https://github.com/jpetazzo/pipework/archive/master.zip
1
unzip master.zip
1
cd pipework-master/
1
cp pipework /usr/local/bin/

pipework 网桥 容器 id IP/24@GATEWAY
