介绍
基本信息
作者：朱明宇
名称：自动化部署 LNMP + SSL 平台
作用：自动化安装 LNMP + SSL，即通过 Linux、Nginx、MariaDB、PHP、php-fpm、SSL，实现 HTTPS
使用方法
1. 将网站的网页数据备份、网站的 SSL 公钥、网站的 SSL 私钥、网站的数据库备份和本脚本，5 个文件放在同一目录下
2. 如果没有网站的数据库备份则将网页数据备份、网站的 SSL 公钥、网站的 SSL 私钥和本脚本，4 个文件放在同一目录下
3. 在此脚本的分割线内写入相应的内容
4. 服务器都要开启 SELinux
5. 给此脚本添加执行权限
6. 执行此脚本：./<此脚本>
脚本分割线里的变量
1. webdomain=”eternalcenter.com” #网站的域名，注意不要在前面加任何前缀
2. webtar=”eternalcenter-backup-*.tar.gz”网站的网页数据备份，如果没有这个备份，可以下载一个开源的 WordPress 网页程序
3. webcrt=”eternalcenter.com.crt” #网站 SSL 的公钥，可以自己创建也可以在 FreeSSL 上申请
4. webkey=”eternalcenter.com.key” #网站 SSL 的私钥，可以自己创建也可以在 FreeSSL 上申请
5. sqlbackup=”eternalcenter-backup-*.sql” #网站数据库数据备份，如果没有这个备份（数据库是全量备份），则这里可以为空
6. db=”ec” #网站在数据库中库
7. dbuser=”ec” #网站在数据库中的用户
8. dbuserpw=”eternalcenter” #网站在数据库中的用户密码
9. dbrootpw=”eternalcenter” #数据库的 root 密码
注意
1. 服务器的系统需要是 CentOS 8 版本
2. 服务器系统要配置好可用的软件源
3. 服务器要能够连接外网
