docker實戰centos 7.4 安裝docker
首發：arppinging
一、docker安裝條件
1.64 bit cpu
2.linux kernel 3.10+
3.linux kernel 支援 cgroups and namespaces
centos 7.4 x64為的滿足條件。實際上centos 6.x系列也能安裝docker。
二、下載和安裝yum源
下載yum檔案
[[email protected] yum.repos.d]# wget https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/centos/docker-ce.repo
修改yum檔案，因為yum檔案中的地址為docker官方地址，下載比較慢
vim中替換網址為清華的地址:
%[email protected]://download.docker.com/@https://mirrors.tuna.tsinghua.edu.cn/docker-ce/@yum repolist檢視
[[email protected] yum.repos.d]# yum repolist 已載入外掛：fastestmirror, langpacks base | 3.6 kB 00:00:00 docker-ce-stable | 3.5 kB 00:00:00 extras | 3.4 kB 00:00:00 updates | 3.4 kB 00:00:00 zabbix | 2.9 kB 00:00:00 zabbix-non-supported | 951 B 00:00:00 (1/6): base/7/x86_64/group_gz | 166 kB 00:00:01 (2/6): updates/7/x86_64/primary_db | 1.3 MB 00:00:00 (3/6): extras/7/x86_64/primary_db | 153 kB 00:00:01 (4/6): base/7/x86_64/primary_db | 6.0 MB 00:00:01 (5/6): docker-ce-stable/x86_64/primary_db | 19 kB 00:00:02 (6/6): docker-ce-stable/x86_64/updateinfo | 55 B 00:00:03 Loading mirror speeds from cached hostfile * base: mirrors.cn99.com * extras: mirrors.cn99.com * updates: mirrors.cn99.com 源標識 源名稱 狀態 base/7/x86_64 CentOS-7 - Base 10,019 docker-ce-stable/x86_64 Docker CE Stable - x86_64 25 extras/7/x86_64 CentOS-7 - Extras 312 updates/7/x86_64 CentOS-7 - Updates 574 zabbix/x86_64 Zabbix Official Repository - x86_64 236 zabbix-non-supported/x86_64 Zabbix Official Repository non-supported - x86_64 4 repolist: 11,170
可以看到有docker-ce了。docker現有兩個版本，一個是付費的商業版(docker-ee),一個是免費的社群版(docker-ce)
三、安裝docker
[[email protected] yum.repos.d]# yum install docker-ce -y
已載入外掛：fastestmirror, langpacks

使用者ID : "Docker Release (CE rpm) < 四、配置網路加速器
這裡我配置的是官網的加速器，大家可以配置和阿里雲的加速器，比較快。
mkdir /etc/docker
vim /etc/docker/daemon.json
{
"registry-mirrors":["https://registry.docker-cn.com"]
}如果加速檔案配置不正確，啟動服務時會報錯
