CentOS-7服务器基础环境搭建

一、更换阿里云yum镜像

yum install -y wget

• 1.备份本地yum源

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo_bak

2 获取阿里yum源配置文件

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

• 更新cache

yum makecache

• 查看

yum -y update

二、基础工具安装

• 安装netstat

yum install -y net-tools  lrzsz vim wget lsof

三、修改静态IP地址

vi /etc/sysconfig/network-scripts/ifcfg-eth0

• 添加/修改如下配置

ONBOOT=yes
BOOTPROTO=static
NETMASK=255.255.255.0
IPADDR=192.168.0.163
GATEWAY=192.168.0.1
DNS1=114.114.114.114 
DNS2=8.8.8.8

• 重启网卡服务

/etc/init.d/network restart
或使用命令：
service network restart

关闭防火墙

临时关闭防火墙命令。重启电脑后，无效
systemctl stop firewalld
永久关闭防火墙命令。重启后，有效。
systemctl disable firewalld
查看防火墙状态
systemctl status firewalld

修改主机名

hostnamectl set-hostname node01

设置主机间免密登录

ssh-keygen
ssh-copy-id [email protected]

yum安装nginx

• 安装nginx的yum源

rpm -ivh http://nginx.org/packages/centos/7/noarch/RPMS/nginx-release-centos-7-0.el7.ngx.noarch.rpm

                  docker-selinux \
                  docker-engine

• 安装依赖的工具包

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo

• 安装Docker CE

sudo yum makecache fast

安装最新版本的Docker CE
sudo yum install docker-ce

安装指定版本，列出可用版本
yum list docker-ce.x86_64  --showduplicates | sort -r
安装
sudo yum install docker-ce-

• 启动Docker

sudo systemctl start docker
sudo systemctl enable docker

{
  "registry-mirrors": ["https://n0st2wzy.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
