安装过程中不使用图形界面的新建分区，就不会有100M分区的问题。后续安装只要在命令行新建的分区中进行就可以。（注：用图形界面新建分区，会自动产生一个100M隐藏分区）。具体操作如下：安装Windows2008R2进行到【开始安装】界面的时候，不点击【开始安装】，也不点击【修复计算机】，直接按快捷键“Shift+F10”打开CMD命令行，然后输入>diskpart.exe进入diskpart命令窗口。然后执行以下命令：>list disk     【查看硬盘编号，大小，有U盘的话注意辨别】>select disk 0【选择硬盘编号，使之处于选中焦点状态】>create partition primary size=25064 【创建主分区，后面的数字是大小，单位MB】>format fs=ntfs quick 【格式化主分区，格式为ntfs格式】>create partition extended 【创建扩展分区，如果已有，在图形界面中错误的删掉了系统C盘，这步可不操作】>exit 【退出程序】关闭CMD命令窗口，开始安装，就可以避免100M隐藏分区了。注意，不要在图形界面删除分区再新建，本人经常这样做，但在windows2008R2等新系统就不行了，这样会产生100M隐藏分区。后面的自动安装就可以了。

Apache PHP Server Issue : Warning: POST Content-Length exceeding the limit PHP Warning: POST Content-Length of xxxxx bytes exceeds the limit of xxxxxx bytes in Unknown on line 0You receive the “POST Content-Length” error message when a file greater than the size defined in the php.ini file is uploaded via the browser.The file you are uploading using the POST method should not exceed the value of post_max_size defined in php.ini file. If it does, it results in the above error message.Solution:In case you are looking to upload a larger file size, you need to increase the value of “post_max_size” in php.ini.1) To locate the exact php.ini file, your PHP is using php -i | grep php.ini 2) Edit the php configuration file pico /usr/local/lib/php.ini 3) If you are looking to upload a file of 30M, set post_max_size and to upload_max_filesize to 40M. post_max_size = 40M upload_max_filesize = 40M 4) Save the file and restart the httpd service service httpd restart cha...

centos下安装php的ZipArchive扩展 系统：centos6.5 64位系统 下载ZipArchivewget http://pecl.php.net/get/zip-1.12.4.tgz 解压:tar zxvf zip-1.12.4.tgz 切换到zip-1.12.4目录一看，没有configure，这怎么编译呢，于是网上一 阵狂搜。后来在意个论坛的一片帖子的回复中有人提到了phpize，我也试着执行了一下phpize命令，提示没有该命令，于是又是一阵狂搜。原来phpize是php.devel带的，于是又安装了php.devel，命令为：yum -y install php.devel 然后再执行phpize，接着ls一下，果然configure出现了，然后执行:./configure --with-php-config=/usr/bin/php-config 出现错误，提示缺少zlib什么的，于是执行yum -y install zlib-devel 进行安装，然后重新./configure --with-php-config=/usr/bin/php-config 接着make，但是又遇到了错误，提示缺少pcre啥的，于是执行yum install pcre-devel 然后make && make install 搞定！

介绍一个强大的分析网络的shell脚本，此脚本是从EZHTTP拆分出来的，觉得有必要单独介绍下。脚本运行效果截图：此脚本包含的功能有：1、实时监控任意网卡的流量2、统计10秒内平均流量3、统计每个端口在10秒内的平均流量，基于客户端和服务端端口统计。可以看出哪些端口占流量比较大，对于web服务器，一般是80端口。其它端口受到攻击时，也有可能其它端口流量比较大。所以此功能可以帮助我们端口流量是否正常。4、统计在10s内占用带宽最大的前10个ip。此项功能可以帮助我们来查出是否有恶意占用带宽的ip。5、统计连接状态。此项功能可以让我们看出哪些连接状态比较大。如果SYN-RECV状态比较多的话，有可以受到半连接攻击。如果ESTABLISED非常大，但通过日志发现没有那么多请求，或者通过tcpdump发现大量ip只建立连接不请求数据的话，可能是受到了全连接攻击，这时候如果你使用的是nginx服务器，可以在配置文件增加listen 80 deferred来防止。6、统计各端口连接状态。当可能受到攻击时，此项功能可以帮助我们发现是哪个端口受到攻击。7、统计端口为80且状态为ESTAB连接数最多的前10个IP。此项功能可以帮助我们来找出创建连接过多的Ip，进而屏蔽。8、统计端口为80且状态为SYN-REC...
