使用 shell 脚本实现 LANMP 一键安装

使用 shell 脚本来实现 LANMP 系统的一键安装。使用的操作系统是 CentOS 6 ，不区分 32 位和 64 位，要求机器可以连通互联网。支持 LAMP 和 LNMP ，MySQL 支持 5.1 和 5.6 两个版本， php 支持 5.3 和 5.6 两个版本， apache 2.2 ，nginx 1.8。

代码如下：

#!/bin/bash
echo "It will install lamp or lnmp."
sleep 1

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

# check last command is OK or Not.
function check_ok()
{
    if [ $? != 0 ];then
        echo "Error, Check the error log."
        exit 1
    fi
}

# close seliux
function close_selinux()
{
    sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config
    selinux_s=`getenforce`
    if [ $selinux_s == "Enforcing"  -o $selinux_s == "enforcing" ];then
        setenforce 0
    fi
}

# close iptables
function clear_iptables()
{
    iptables-save > /etc/sysconfig/iptables_`date +%s`
    iptables -F
    service iptables save
}

# if the packge installed ,then omit.
function myum() {
    if ! rpm -qa|grep -q "^$1" ;then
        yum install -y $1
        check_ok
    else
        echo $1 already installed.
    fi
}
