请注意阅读git上的README.md

1、本脚本支持离线与在线安装：

脚本自行判断连接：

curl -I -m 10 -o /dev/null -s -w %{http_code}'\n' 

是否返回200，返回200表示有网络，将使用yum安装相关依赖，否则视为无网络情况，将使用rpm -ivh方式安装所需依赖包（在无网络条件时，请切记上传packages_nginx、packages_gcc否则脚本将无法自动安装自动安装部署）

2、脚本也可以自行根据需要修改于在线使用wget直接下载相关软件包，这样会更灵活

（1）pcre8.44软件包下载地址如下：

（2）zlib1.2.11软件包下载址如下：

（3）openssl1.1.1g软件包下载地址如下：

（4）nginx1.19.1软件包下载地址如下：

3、所有gcc依赖包、nginx依赖包下载地址：

4、nginx服务已添加自启动，启停采用systemctl管理

停止# systemctl stop nginx启动# systemctl start nginx

5、脚本内容如下，请参阅，执行如有疑问，请反馈给我修改，谢谢支持：
