    使用shell脚本安装lnmp的方法步骤

    1、简介

    使用shell脚本安装lnmp,纯粹是偷懒,平时安装一些东西都写成脚本了,方便以后在其他机器安装的时候不用再去查找文档。

    2、环境说明

    阿里云ECS(1G1核)CentOS 7.4 64位

    3、shell脚本

    3.1   cnl_function.sh

    #!/bin/bash
    #chennailuan's function
    
    
    #check last command id Ok or not.
    check_ok(){
      if [ $? != 0 ]
      then 
        echo Error,Check the error log.
        exit 1
      fi
    }
    
    #if the packge installed ,then omit
    myum(){
      if ! rpm -qa|grep -q "^$1"
      then 
        yum install -y $1
        check_ok
      else
        echo $1 already installed.
      fi
    }
    
    #check service is running or not ,example nginx ,httpd ,php-fpm
    check_service(){
      if [ $1 == "phpfpm" ]
      then
        s="php-fpm"
      else
        s=$1
       fi
      
      n=`ps aux | grep $s | wc -l`
      if [ $n -gt 1 ]
      then
        echo "$1 service is already started."
      else 
        if [ -f /etc/init.d/$1 ]
        then
          /etc/init.d/$1 start

      lnmp
    else
      echo "Cancel the installation."
    fi

    4、开始安装

    上面上个文件放在同一目录

      

    在shell目录执行 sh cnl_install_lnmp.sh

      

    输入 Y 确认执行安装,需要安装的安装包会自己检查,本人在自己的几台服务器都测试过,安装正常。

    安装完会自己加到系统服务 ,并启动。

    以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持脚本之家。
