Install Docker
I installed Centos7 in a virtual machine, linux 3.10 kernel, docker official says at least 3.8 or above, and recommends 3.10 or above (linux kernel 3.8 or above is required under ubuntu, the RHEL/Centos kernel has been patched, and the centos6.5 version is fine-this is fine try)
1, log in with the root account, check the kernel version as follows
[root@localhost ~]# uname -a Linux localhost.localdomain 3.10.0-957.el7.x86_64 #1 SMP Thu Nov 8 23:39:32 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
2, update the yum package to the latest
[root@localhost ~]# yum update Plugin loaded: fastestmirror Loading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.cn99.com base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 Resolving dependencies --> checking transaction ---> Package NetworkManager.x86_64.1.1.12.0-6.el7 will be upgraded ---> Package NetworkManager.x86_64.1.1.12.0-10.el7_6 will be updated
(To select confirmation during the period, just enter y)
3, install the required software packages, yum-util provides the yum-config-manager function, and the other two are dependent on the devicemapper driver
[root@localhost ~]# yum install -y yum-utils device-mapper-persistent-data lvm2 Plugin loaded: fastestmirror Loading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.cn99.com Package device-mapper-persistent-data-0.7.3-3.el7.x86_64 is installed and up to date Package 7:lvm2-2.02.180-10.el7_6.8.x86_64 is installed and up to date Resolving dependencies --> checking transaction ---> Package yum-utils.noarch.0.1.1.31-50.el7 will be installed --> Processing dependency python-kitchen, which is required by package yum-utils-1.1.31-50.el7.noarch ... ...
4, set yum source (choose one)
#central warehouse yum-config-manager --add-repo http://download.docker.com/linux/centos/docker-ce.repo #Ali Warehouse yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[root@localhost ~]# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo Plugin loaded: fastestmirror adding repo from: https://download.docker.com/linux/centos/docker-ce.repo grabbing file https://download.docker.com/linux/centos/docker-ce.repo to /etc/yum.repos.d/docker-ce.repo repo saved to /etc/yum.repos.d/docker-ce.repo
5, you can view all docker versions in all warehouses, and select a specific version to install
[root@localhost ~]# yum list docker-ce --showduplicates | sort -r Plugin loaded: fastestmirror Installable Packages * updates: mirrors.cn99.com Loading mirror speeds from cached hostfile * extras: mirrors.aliyun.com docker-ce.x86_64 3:19.03.2-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.1-3.el7 docker-ce-stable docker-ce.x86_64 3:19.03.0-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.8-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.7-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.6-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.5-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.4-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.3-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.2-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.1-3.el7 docker-ce-stable docker-ce.x86_64 3:18.09.0-3.el7 docker-ce-stable docker-ce.x86_64 18.06.3.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.2.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.1.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.06.0.ce-3.el7 docker-ce-stable docker-ce.x86_64 18.03.1.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 18.03.0.ce-1.el7.centos docker-ce-stable docker-ce.x86_64 17.12.1.ce-1.el7.centos docker-ce-stable
6, install Docker, command: yum install docker-ce-version number, I chose docker-ce-18.03.1.ce, as follows
[root@localhost ~]# yum install docker-ce-18.03.1.ce Plugin loaded: fastestmirror Loading mirror speeds from cached hostfile * base: centos.ustc.edu.cn * extras: mirrors.aliyun.com * updates: mirrors.cn99.com Resolving dependencies --> checking transaction ---> Package docker-ce.x86_64.0.18.03.1.ce-1.el7.centos will be installed
(To select confirmation during the period, just enter y)
7, Start Docker, command: systemctl start docker, and then add startup, as follows
[root@localhost ~]# systemctl start docker [root@localhost ~]# systemctl enable docker Created symlink from /etc/systemd/system/multi-user.target.wants/docker.service to /usr/lib/systemd/system/docker.service. [root@localhost ~]# docker version Client: Version: 18.03.1-ce API version: 1.37 Go version: go1.9.5 Git commit: 9ee9f40 Built: Thu Apr 26 07:20:16 2018 OS/Arch: linux/amd64 Experimental: false Orchestrator: swarm Server: Engine: Version: 18.03.1-ce API version: 1.37 (minimum version 1.12) Go version: go1.9.5 Git commit: 9ee9f40 Built: Thu Apr 26 07:23:58 2018 OS/Arch: linux/amd64 Experimental: false
8, set docker source
