CentOS上面用Shell脚本一键安装LNMP环境

由于Nginx是一款高性能的HTTP和反向代理服务器。Nginx在反向代理，Rewrite规则，稳定性，静态文件处理，内存消耗等方面表现了很强的优势。因此公司线上和测试环境的WEB服务大多数采用的是LNMP环境，经常要进行LNMP环境的搭建，下面是用SHELL脚本写的一键安装LNMP环境的脚本。

推荐阅读：

1）系统环境介绍
Centos 5.8 64位 （已测试）
Nginx: nginx-1.4.1.tar.gz
PHP:  php-5.3.27.tar.gz
Mysql: mysql-5.6.5-m8.tar.gz

2）一键安装LNMP环境

cd /root/sh
wget http://sourceforge.net/projects/opensourcefile/files/Install_Centos_LNMP_v.0.1.sh/download
Install_Centos_LNMP_v.0.1.sh

3)查看LNMP一键安装脚本的SHELL脚本
cat Install_Centos_LNMP_v.0.1.sh
#!/bin/bash
#author:sfzhang
mkdir -p /software
cd /software
wget http://sourceforge.net/projects/opensourcefile/files/Centos_LNMP_v.0.1.tar.gz/download
if [ $? -eq 0 ]
  then
  unzip Centos_LNMP_v.0.1.tar.gz
  rm -f Centos_LNMP_v.0.1.tar.gz
else
  echo "Downloading http://sourceforge.net/projects/opensourcefile/files/Centos_LNMP_v.0.1.tar.gz/download failured!"
  exit 1
fi
echo "Installing lnmp depend  packages... "
sh /software/install_packages.sh
if [ $? -eq 0 ]
  then
    echo "Lnmp depend packages install sucessfull!"
else
    echo "Lnmp depend packages install failured!"
  exit 1
fi
echo "Installing php library files..."
sh /software/install_php_lib.sh
if [ $? -eq 0 ]
  then
    echo "PHP library install sucessfull!"
else
    echo "PHP library install failured!"
  exit 1
fi
echo "Installing mysql,please waitting..."
sh /software/install_mysql_5.6.sh
if [ $? -eq 0 ]
  then
    echo "mysql install sucessfull!"
else
    echo "mysql install failured!"
  exit 1
fi
echo "Now Installing php,please waitting..."
sh /software/install_php_5.3.sh
if [ $? -eq 0 ]
  then
    echo "PHP install sucessfull!"
else
    echo "PHP install failured!"
  exit 1
fi
echo "Installing php extensions...."
sh /software/install_php_ext.sh
if [ $? -eq 0 ]
  then
    echo "PHP extensions install sucessfull!"
else
    echo "PHP extensions install failured!"
  exit 1
fi
echo "Installing nginx....."
sh /software/install_nginx.sh
if [ $? -eq 0 ]
  then
    echo "Nginx install sucessfull!"
else
    echo "Nginx install failured!"
  exit 1
fi
echo "optimizing the environment of the lnmp!"
sh /software/install_optimiz.sh
if [ $? -eq 0 ]
  then
    echo "optimizing the environment of the lnmp sucessfull!"
else
    echo "optimizing the environment of the lnmp failured!"
  exit 1
fi
echo "Congratulations to you,a key installation LNMP is successful!"

    脚本说明：该脚本用(if...fi)语句共分为以下8个部分,方便脚本的可读性，并更具不同的需求方便用户自定义安装，比如需要安装Nginx,只需手工执行sh /software/install_nginx.sh这个脚本即可，如果需要安装mysql，则执行 /software/install_mysql_5.6.sh 这个脚本。

  1.下载LNMP源码包及其各部分的安装脚本。
  2.yum安装LNMP所依赖的包。
  3.源码安装PHP所需要的库文件。
  4.源码安装mysql数据库。
  5.源码安装PHP。
  6.源码安装PHP扩展。
  7.源码安装NGINX。
  8.优化LNMP性能。
