centos 安装并配置为系统服务- nginx脚本

前提：在   /root  下

/root 下有nginx压缩文件 

nginx-1.20.2.tar.gz

创建脚本文件 

vim startNginx

脚本内容

echo "创建nginx文件夹 /mydata/nginx"
sleep 2
  mkdir -p /mydata/nginx
echo "创建静态资源文件夹 /mnt/data"
sleep 2
  mkdir -p /mnt/data
    echo "开始安装nginx的必要组件……"
    #安装 nginx 需要先将官网下载的源码进行编译，编译依赖 gcc 环境
    yum install gcc-c++
    #pcre是一个perl库，包括perl兼容的正则表达式库，nginx的http模块使用pcre来解析正则表达式，所以需要安装pcre库
    yum install -y pcre pcre-devel
    #zlib库提供了很多种压缩和解压缩方式nginx使用zlib对http包的内容进行gzip，所以需要安装
    yum install -y zlib zlib-devel
    #nginx 不仅支持 http 协议，还支持 https（即在ssl协议上传输http），所以需要在 Centos 安装 OpenSSL 库
    yum install -y openssl openssl-devel
