Centos 7离线部署Nginx 高效省时

1. 给脚本执行权限：chmod +x install_nginx.sh
2. 以root用户运行：sudo ./install_nginx.sh

脚本如下：

#!/bin/bash
# Nginx一键化部署脚本（修复版本）
# 需要以root权限运行

set -e # 任何命令失败时立即退出脚本

# 定义彩色输出函数
color_echo() {
    local color=$1
    shift
    case $color in
        red) echo -e "\033[31m$@\033[0m" ;;
        green) echo -e "\033[32m$@\033[0m" ;;
        yellow) echo -e "\033[33m$@\033[0m" ;;
        *) echo "$@" ;;
    esac
}
