centos6.5 64bit 上安装 docker-1.7.1 权威实践教程

1.检查系统和内核版本

[root@centos01 ~]# uname -r 2.6.32-431.el6.x86_64 [root@centos01 ~]# cat /etc/redhat-release CentOS release 6.5 (Final)

2.检查系统是否已经安装了docker

[root@centos01 ~]# rpm -qa |grep -i docker

3.centos6.5需要安装额外的EPEL镜像源才可以用yum来拉取安装docker,所以先安装EPEL镜像源

[root@centos01 ~]# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm --2017-12-13 23:08:48-- https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm Resolving dl.fedoraproject.org... 209.132.181.23,209.132.181.24,209.132.181.25 Connecting to dl.fedoraproject.org|209.132.181.23|:443... connected.

[root@centos01 ~]# ls -lt epel-release-latest-6.noarch.rpm -rw-r--r--. 1 root root 14540 Nov 5 2012 epel-release-latest-6.noarch.rpm [root@centos01 ~]# rpm -ivh epel-release-latest-6.noarch.rpm warning: epel-release-latest-6.noarch.rpm.1: Header V3 RSA/SHA256 Signature,key ID 0608b895: NOKEY Preparing... ########################################### [100%] 1:epel-release ########################################### [100%]

4.开始安装docker服务器端

[root@centos01 ~]# yum install docker-io -y Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * base: mirrors.163.com * epel: ftp.cuhk.edu.hk * extras: ftp.sjtu.edu.cn * updates: mirrors.163.com Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package docker-io.x86_64 0:1.7.1-2.el6 will be installed --> Processing Dependency: bridge-utils for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: device-mapper-libs for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: libcgroup for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: libdevmapper.so.1.02(Base)(64bit) for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: lxc for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: xz for package: docker-io-1.7.1-2.el6.x86_64 --> Processing Dependency: libdevmapper.so.1.02()(64bit) for package: docker-io-1.7.1-2.el6.x86_64 --> Running transaction check ---> Package bridge-utils.x86_64 0:1.2-10.el6 will be installed ---> Package device-mapper-libs.x86_64 0:1.02.117-12.el6_9.1 will be installed --> Processing Dependency: device-mapper = 1.02.117-12.el6_9.1 for package: device-mapper-libs-1.02.117-12.el6_9.1.x86_64 --> Processing Dependency: libudev.so.0()(64bit) for package: device-mapper-libs-1.02.117-12.el6_9.1.x86_64 ---> Package libcgroup.x86_64 0:0.40.rc1-24.el6_9 will be installed ---> Package lxc.x86_64 0:1.0.11-1.el6 will be installed --> Processing Dependency: lua-lxc(x86-64) = 1.0.11-1.el6 for package: lxc-1.0.11-1.el6.x86_64 --> Processing Dependency: lua-alt-getopt for package: lxc-1.0.11-1.el6.x86_64 --> Processing Dependency: liblxc.so.1()(64bit) for package: lxc-1.0.11-1.el6.x86_64 ---> Package xz.x86_64 0:4.999.9-0.5.beta.20091007git.el6 will be installed --> Processing Dependency: xz-libs = 4.999.9-0.5.beta.20091007git.el6 for package: xz-4.999.9-0.5.beta.20091007git.el6.x86_64 --> Running transaction check ---> Package device-mapper.x86_64 0:1.02.117-12.el6_9.1 will be installed ---> Package libudev.x86_64 0:147-2.73.el6_8.2 will be installed ---> Package lua-alt-getopt.noarch 0:0.7.0-1.el6 will be installed ---> Package lua-lxc.x86_64 0:1.0.11-1.el6 will be installed --> Processing Dependency: lua-filesystem for package: lua-lxc-1.0.11-1.el6.x86_64 ---> Package lxc-libs.x86_64 0:1.0.11-1.el6 will be installed --> Processing Dependency: rsync for package: lxc-libs-1.0.11-1.el6.x86_64 ---> Package xz-libs.x86_64 0:4.999.9-0.3.beta.20091007git.el6 will be updated ---> Package xz-libs.x86_64 0:4.999.9-0.5.beta.20091007git.el6 will be an update --> Running transaction check ---> Package lua-filesystem.x86_64 0:1.4.2-1.el6 will be installed ---> Package rsync.x86_64 0:3.0.6-12.el6 will be installed --> Finished Dependency Resolution

Complete!

5.检查是否已经安装docker 及版本

[root@centos01 ~]# rpm -qa |grep -i docker docker-io-1.7.1-2.el6.x86_64

[root@centos01 ~]# docker version Client version: 1.7.1 Client API version: 1.19 Go version (client): go1.4.2 Git commit (client): 786b29d/1.7.1 OS/Arch (client): linux/amd64 Server version: 1.7.1 Server API version: 1.19 Go version (server): go1.4.2 Git commit (server): 786b29d/1.7.1 OS/Arch (server): linux/amd64

6.启动docker 服务 [root@centos01 ~]# service docker start Starting cgconfig service: [ OK ] Starting docker: [ OK ]

[root@centos01 ~]# ps -ef | grep docker root 1200 1 1 23:18 pts/0 00:00:00 /usr/bin/docker -d root 1315 1057 0 23:19 pts/0 00:00:00 grep docker

[root@centos01 ~]# netstat -an | grep docker unix 2 [ ACC ] STREAM LISTENING 12699 /var/run/docker.sock

7.设置docker 开机自启动 [root@centos01 ~]# chkconfig docker on [root@centos01 ~]# chkconfig --list | grep docker docker 0:off 1:off 2:on 3:on 4:on 5:on 6:off

8.从docker hub中下载centos 镜像

[root@centos01 ~]# docker pull centos latest: Pulling from centos 99d067612410: Pull complete fb2a47779ef8: Pull complete 358bf47a7a64: Pull complete Digest: sha256:7192ec204ee4b953a9c9212ebd78575a334d041333d8f58387aa648f72a7fd8a Status: Downloaded newer image for centos:latest

9.检查centos镜像是否已经下载成功

[root@centos01 ~]# docker images centos REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE centos latest 358bf47a7a64 13 days ago 203.5 MB [root@centos01 ~]#

10.运行一个简单的脚本测试镜像，其实就是进入docker 镜像容器里

[root@centos01 ~]# docker run -i -t centos /bin/bash [root@8bff017f6fd2 /]# df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/docker-8:2-392684-8bff017f6fd2a261b2f44925a51c3d16cb25ef17e098f44af2bc69e6c47c6e08 9.9G 365M 9.0G 4% / tmpfs 116M 0 116M 0% /dev shm 64M 0 64M 0% /dev/shm /dev/sda2 18G 1.7G 16G 10% /etc/hosts [root@8bff017f6fd2 /]# cat /etc/redhat-release CentOS Linux release 7.4.1708 (Core) [root@8bff017f6fd2 /]# uname -r 2.6.32-431.el6.x86_64 [root@8bff017f6fd2 /]#

上述表明已经成功。
