脚本实现自动化安装lamp&lnmp

#备注：前提是将lnmp和lnmp自动化脚本写好放在相应的路径, 脚本已写好，请查看我博客中的 shell脚本 专栏！

 #!/bin/bash
 #安装lamp或者lnmp

 path=/server/scripts        #定义两个脚本路径
 [ ! -d "$path" ] && mkdir -p $path

 cat <<EOF
     1.[ install lamp ]
     2.[ install lnmp ]
     3.[ exit ]
     please input num you want:
 EOF

 read num
 [[ ! $num =~ [1-3] ]] && {
     echo "the num you input must be:  1 | 2 | 3 "
     exit 4
 }

 [ $num -eq 1 ] && {            #如果用户选择1，则执行lamp安装命令
     echo "start installing lamp..."
     [ -x "$path/lamp.sh" ] && {        #判断脚本是否可执行
         echo "$path/lamp.sh does not exist or can not be exec"
         exit 1
     }
 source $path/lamp.sh
 exit $?
 }

 [ $num -eq 2 ] && {            #如果用户选择2，则执行lnmp安装命令
     echo "start installing lnmp..."
     [ -x "$path/lnmp.sh" ] && {        #判断脚本是否可执行
         echo "$path/lnmp.sh does not exist or can not be exec"
         exit 1
     }
 source $path/lnmp.sh
 exit $?
 }

 [ $num -eq 3 ] && {
     echo goodbye!
     exit 3
 }
