Docker 实战之 CentOS7 系统环境配置

LinuxProbe

本文档详细介绍 Docker 实战之 CentOS7 系统环境配置，为后期安装 Docker 做准备。

0 优化环境

直接复制以下代码，优化环境，如果执行了一下代码，那么接下来的1和2步骤可以不用再操作了。

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/null1 关闭SELinux和防火墙
[root@Docker ]# vim /etc/selinux/configSELINUX=disabled[root@Docker ]# setenforce 0[root@Docker ]# getenforcePermissive2 关闭Firewalld 和 iptables
[root@Docker ]# systemctl stop firewalld[root@Docker ]# systemctl disable firewalld[root@Docker ]# systemctl status firewalld[root@Docker ]# iptables -F3 配置 yum 源

手动改时间： date -s "2019-09-09 19:19"

7 配置 pip 镜像源，方便快速下载python库（这一步很重要）
[root@Docker ]# mkdir /.pip[root@Docker ]# vim  /.pip/pip.conf  #写入下以内容[global]index-url = http://mirrors.aliyun.com/pypi/simple/[install]trusted-host=mirrors.aliyun.com8  配置网卡信息
[root@Docker ]# vim /etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=EthernetPROXY_METHOD=noneBROWSER_ONLY=noBOOTPROTO=staticDEFROUTE=yesIPV4_FAILURE_FATAL=noNAME=ens33DEVICE=ens33ONBOOT=yesIPADDR=192.168.10.7GATEWAY=192.168.10.2NETMASK=255.255.255.0总结

以上的操作就是 CentOS7 系统环境配置的过程，为安装 Docker 做好准备。想看怎么安装 Docker 的朋友请持续关注我的文章，希望我的文章能给大家带来帮助。
