阿里云服务器web环境Apache+Nginx重新换回Tengine

Apache+Nginx这种方式有好有坏，应用在一些流量大的站点是可以有的，而且效率惊人，具体怎么样不扯那么多，不好之处就是是

会消耗服务器过多资源， 这样下来，服务器配置就高了！所以一般中小站点，没什么必要这种搭配使用。比如公司网站这类流量少

的，用一种即可。客家网络之前是Apache+Nginx的方式撑了8个月，整整八个月！一点问题没有。下面介绍下阿里云服务器web环境

Apache+Nginx重新换回Tengine. 

大致的步骤：

第一步：比较敏感的操作，重装系统。一般是用centos 6.5 32位/64位  

第二步：挂载数据盘，然后恢复数据，确保数据完好，一般提前备份快照！

第三步：安装军哥lnmp，现在是1.1，非常赞的集成，关键自主管理及其方便，不、譬如升级PHP、Apache等扩展都很灵活，推荐

使用。

安装什么http://lnmp.org/都有详细的描述。安装完成了LNMP先不要配置虚拟主机，直接平滑升级Tengine

之前有人做过了脚本，昨晚也测试确实可用！链接如下：http://www.zntec.cn/archives/upgrade_tengine.html

升级脚本如下：

#!/bin/bash
PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin:~/bin
export PATH

# Check if user is root
if [ $(id -u) != "0" ]; then
    echo "Error: You must be root to run this script, please use root to install lnmp"
    exit 1
fi

clear
echo "========================================================================="
echo "Upgrade Tengine for LNMP,  Modify by Tomas"
echo "========================================================================="
echo "LNMP is tool to auto-compile & install Tengine+MySQL+PHP on Linux "
echo ""

echo "========================================================================="

old_nginx_version=`echo $nv | cut -c22-`
#echo $old_nginx_version

if [ "$1" != "--help" ]; then

#set nginx version

	nginx_version=""
	echo "Current tengine Version:$old_nginx_version"
	echo "Please input tengine version you want:"
	echo "You can get version number from http://tengine.taobao.org/download_cn.html"
	read -p "(example: 2.0.2 ):" nginx_version
	if [ "$nginx_version" = "" ]; then
		echo "Error: You must input tengine version!!"
		exit 1
	fi
	echo "==========================="

	echo "You want to upgrade tengine version to $nginx_version"

	echo "==========================="

	get_char()

	SAVEDSTTY=`stty -g`

echo "============================check files=================================="
if [ -s tengine-$nginx_version.tar.gz ]; then
  echo "tengine-$nginx_version.tar.gz [found]"
  else
  echo "Error: tengine-$nginx_version.tar.gz not found!!!download now......"
  wget -c http://tengine.taobao.org/download/tengine-$nginx_version.tar.gz
  if [ $? -eq 0 ]; then
	echo "Download tengine-$nginx_version.tar.gz successfully!"

保存到root目录

执行一下：

sh upgrade_tengine.sh.txt

http://www.zntec.cn/archives/upgrade_tengine.html这篇写的确实可用！搞完就开始配置虚拟主机和LNMP的使用是一样的！

升级成功，网站速度是不是快很多？
