准备工作
给三台机器准备yum，这一步三台机器都做
//搭建yum的脚本 [root@RedHat ~]# cat yum.sh #!/bin/bash curl -o /etc/yum.repos.d/CentOS-Base.repo https://mirrors.aliyun.com/repo/Centos-8.repo sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo sed -i 's#$releasever#8#g' /etc/yum.repos.d/CentOS-Base.repo yum install -y https://mirrors.aliyun.com/epel/epel-release-latest-8.noarch.rpm sed -i 's|^#baseurl=https://download.fedoraproject.org/pub|baseurl=https://mirrors.aliyun.com|' /etc/yum.repos.d/epel* yum clean all && yum makecache //执行脚本 [root@RedHat ~]# bash yum.sh
关闭防火墙和selinux（三台机器都要做）
# systemctl disable --now firewalld # setenforce 0 # vim /etc/selinux/config SELINUX=disabled
搭建nginx（此操作在第一台机上做"192.168.100.20"）
