Docker 實戰(zhàn)之 CentOS7 系統(tǒng)環(huán)境配置

本文檔詳細介紹 Docker 實戰(zhàn)之?CentOS7 系統(tǒng)環(huán)境配置，為后期安裝 Docker 做準備。

0 優(yōu)化環(huán)境

直接復制以下代碼，優(yōu)化環(huán)境，如果執(zhí)行了一下代碼，那么接下來的1和2步驟可以不用再操作了。

sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config &> /dev/nullsetenforce 0systemctl stop firewalldsystemctl disable firewalldiptables -Fsystemctl stop NetworkManager &> /dev/nullsystemctl disable NetworkManager &> /dev/null

1 關(guān)閉SELinux和防火墻

[root@Docker ]# vim /etc/selinux/config

SELINUX=disabled

[root@Docker ]# setenforce 0

[root@Docker ]# getenforce

Permissive

2 關(guān)閉Firewalld 和 iptables

[root@Docker ]# systemctl stop firewalld

[root@Docker ]# systemctl disable firewalld

[root@Docker ]# systemctl status firewalld

[root@Docker ]# iptables -F

3 配置 yum 源

[root@Docker ]# mv /etc/yum.repos.d/Cent* /tmp

[root@Docker ]# vim /etc/yum.repos.d/CentOS7.repo

[aliyun-os]

name=aliyun-os

添加 epel 源

[root@Docker ]# yum install epel-release -y

添加 docker-ce 源

[root@Docker ]# yum install -y yum-utils

[root@Docker ]# yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

[root@Docker ]# cat /etc/yum.repos.d/docker-ce.repo?

[root@Docker ]# yum clean all && yum makecache

4 配置 hostname

[root@Docker ]# vim /etc/hostname

Docker

5 配置/etc/hosts

[root@Docker ]# vim /etc/hosts

127.0.0.1?? localhost localhost.localdomain localhost4 localhostlocaldomain4

::1???????? localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.10.7 Docker

[root@Docker ]# ping $HOSTNAME

6 同步時間

[root@Docker ]# find / -name Shanghai

/usr/share/zoneinfo/Asia/Shanghai

/usr/share/zoneinfo/posix/Asia/Shanghai

/usr/share/zoneinfo/right/Asia/Shanghai

[root@Docker ]# cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

cp: overwrite ‘/etc/localtime’? y

[root@Docker ]# yum install -y ntp ntpdate

[root@Docker ]# systemctl enable ntpd

[root@Docker ]# systemctl start ntpd

[root@Docker ]# ntpdate cn.pool.ntp.org

[root@Docker ]# ntpdate 0.rhel.pool.ntp.org

手動改時間： date -s "2019-09-09 19:19"

7 配置 pip 鏡像源，方便快速下載python庫（這一步很重要）

[root@Docker ]# mkdir /.pip

[root@Docker ]# vim ?/.pip/pip.conf? #寫入下以內(nèi)容

[global]

index-url = http://mirrors.aliyun.com/pypi/simple/

[install]

trusted-host=mirrors.aliyun.com

8? 配置網(wǎng)卡信息

[root@Docker ]# vim /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet

PROXY_METHOD=none

BROWSER_ONLY=no

BOOTPROTO=static

DEFROUTE=yes

IPV4_FAILURE_FATAL=no

NAME=ens33

DEVICE=ens33

ONBOOT=yes

IPADDR=192.168.10.7

GATEWAY=192.168.10.2

NETMASK=255.255.255.0
