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。

• PHP版本5.6.6
• MYSQL版本5.6.26
• NGINX版本1.15.6

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

#get the archive of the system ,i686 or x86_64
ar=`arch`

#close selinux
sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
selinux_s=`getenforce`
if [ $selinux_s == "enforcing" ]
then
setenforce 0
fi

#install some packges

#install epel.
if rpm -qa epel-release > /dev/null
then
rpm -e epel-release
fi
if ls /etc/yum.repos.d/epel-7.repo* > /dev/null 2>&1
then
rm -f /etc/yum.repos.d/epel-7.repo*

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。
