1-docker操作系统安装要求(1-docker operating system installation requirements)

1)操作系统

centos7版本系统,最小化安装

2)vmware net模式

IP配置 需要配置DNS,不然不能ping通域名

TYPE=Ethernet
BOOTPROTO=static
NAME=ens33
UUID=ab5bdcb8-4a71-473c-856d-c1e6a2b8b326
DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.40.180
NETMASK=255.255.255.0
GATEWAY=192.168.40.2
DNS1=192.168.40.2

 3)安装阿里源

cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak
wget http://mirrors.aliyun.com/repo/Centos-7.repo
yum repolist

4)补安装tab提示功能

yum -y install bash-completion

5)系统优化

A)设置主机名
hostnamectl set-hostname master1 && bash

B)关闭防火墙
service iptables stop && systemctl disable iptables
yum install iptables-services -y
service iptables stop && systemctl disable iptables
iptables -F

C)selinux关闭
/etc/selinux/config
SELINUX=disabled

getenforce

D)对时
yum install -y ntp ntpdate
crontab -e
* */1 * * * /usr/sbin/ntpdate cn.pool.ntp.org
systemctl restart crond

DEVICE=ens33
ONBOOT=yes
IPADDR=192.168.40.180
NETMASK=255.255.255.0
GATEWAY=192.168.40.2
DNS1=192.168.40.2

cd /etc/yum.repos.d/
mkdir bak
mv *.repo bak
wget http://mirrors.aliyun.com/repo/Centos-7.repo
yum repolist

4) Supplementary installation tab prompt function

yum -y install bash-completion
