一、课前准备

二、环境简述

  • node20, 192.168.26.20/24, gw: 192.168.26.2, ansible管理端
  • node21, 192.168.26.21/24, gw: 192.168.26.2，被管理端
  • node22, 192.168.26.22/24, gw: 192.168.26.2，被管理端
  • node23, 192.168.26.23/24, gw: 192.168.26.2, 被管理端

三、搭建流程

  1. 最小化安装1台CentOS，安装后关机，给虚拟机创建一个快照；
  2. 从快照克隆新虚拟机，使用链接克隆方式，克隆出4台虚拟机；
  3. 打开这4台虚拟机，配置静态ip地址、主机名，完成后开机；
  4. 在node20上安装Ansible，使用ssh-keygen生成服务端公钥对；
  5. 在node20上使用copy-ssh-id命令，与node21/22/23配置无密码访问；
  6. 完成后关机，对node21/22/23创建虚拟机快照；

四、本地配置

  • 下载安装git客户端msi安装包, https://www.git-scm.com/
  • 下载安装VSCode，https://code.visualstudio.com/
  • 在VSCode插件库里安装Remote-SSH插件
  • git客户端安装后桌面右键Git bash here,使用ssh-keygen生成密钥对，使用ssh-copy-id连接node20配置无密码登录

  • 打开VScode，在remote-ssh插件配置文件中填写如下内容，配置文件位置：C:\Users\lixm.ssh\config

    Host 192.168.26.20
HostName 192.168.26.20
User root
Port 22
IdentityFile "C:\Users\lixm\.ssh\id_rsa"
  • 完成后即可在本地Windows远程编辑Linux主机中的文件

五、 LAMP环境搭建步骤

1. Install Base Environment

  • epel-release
  • turn off selinux

2. Install Apache Server

  • Install httpd
  • Set httpd service enable and start service
  • Open http 80/tcp port

3. Install PHP

  • Install remi-repo
  • Install php82 packages
  • Restart httpd

4. Install Mariadb

  • Install mariadb-server
  • Set mariadb service enable and start service
  • Install Python Library PyMySQL
  • Create database wordpressdb
  • Create user wordpress@localhost and grant permission to access wordpressdb

5. Install Wordpress

  • Download wordpress package
  • Unarchive package to target directory
  • Recursive modify files permission
  • Upload httpd virtualhost config file
  • Restart httpd service
  • Upload wordpress config file
