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
      check_ok
    else
      install_$1
     fi
  fi
}

3.2   cnl_install_lnmp_init.sh  

#!/bin/bash
source ./cnl_function.sh

echo "It will install lamp=========================================================================================begin"
#sleep 2

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。
