分析安装包lnmp中的apache.sh脚本

分析shell脚本，学习方法，这个其实是在lnmp环境下再安装apache,实现lnmpa环境。

#!/bin/bash
#定义PATH变量
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
#声明PATH为环境变量
export PATH
# Check if user is root
#id -u 当前用户的uid，也可以使用反引号`id -u`，效果一样，0为root的用户id
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script, please use root to install lnmp"

#这个重点说一下，察看ip,
#通过1次grep,过滤掉不包含inet的行
#2次反向grep也就是取不包含的行，过滤掉包含127.0.0.1和inet6的行
#awk 打印第2列
#tr -d 去掉addr:，这样就只剩下ip
ipv4=`ifconfig -a|grep inet|grep -v 127.0.0.1|grep -v inet6|awk '{print $2}'|tr -d "addr:"`
