设置步骤:
1.勾选 Request Headers 中的 Hide if url contains 过滤项
2.贴入下方正则表达式
1 | REGEX:(?insx)/[^?/]*.(css|ico|jpg|png|gif|bmp|wav)(?.*)?$ |
REGEX: 表示启用正则表达式
(?insx) 设置正则解释的规则, 忽略大小写等.
Fiddler 过滤 css,图片等请求url 正则表达式

树莓派在 shell 下自动挂载 usb 移动存储设备
新建usb存储脚本
1 | nano /etc/udev/rules.d/10-usbstorage.rules |
输入以下内容
1 2 3 4 5 6 7 8 9 10 11 12 13 | KERNEL!="sd*", GOTO="media_by_label_auto_mount_end" SUBSYSTEM!="block",GOTO="media_by_label_auto_mount_end" IMPORT{program}="/sbin/blkid -o udev -p %N" ENV{ID_FS_TYPE}=="", GOTO="media_by_label_auto_mount_end" ENV{ID_FS_LABEL}!="", ENV{dir_name}="%E{ID_FS_LABEL}" ENV{ID_FS_LABEL}=="", ENV{dir_name}="Untitled-%k" ACTION=="add", ENV{mount_options}="relatime,sync" ACTION=="add", ENV{ID_FS_TYPE}=="vfat", ENV{mount_options}="iocharset=utf8,umask=000" ACTION=="add", ENV{ID_FS_TYPE}=="ntfs", ENV{mount_options}="iocharset=utf8,umask=000" ACTION=="add", RUN+="/bin/mkdir -p /media/%E{dir_name}", RUN+="/bin/mount -o $env{mount_options} /dev/%k /media/%E{dir_name}" ACTION=="remove", ENV{dir_name}!="", RUN+="/bin/umount -l /media/%E{dir_name}", RUN+="/bin/rmdir /media/%E{dir_name}" LABEL="media_by_label_auto_mount_end" |
现在可以像在 windows 中热插拨 usb 存储设备了.
发现设置会自动挂载到 /media 目录下. 可自行修改路径, 挂载到其他目录.
Debian Linux shell 高亮显示
编辑登录用户的 ~/.bashrc 文件, 每个用户的 ~ 目录可能不同. 用 echo ~ 即可显示实际目录.
1 | nano ~/.bashrc |

Linux VPS 性能测试工具 UnixBench 脚本
将下面这段保存为 test.sh , 并输入 ./test.sh 即可自动下载安装 UnixBench 进行性能测试.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 | mkdir -p ~/unixbench; cd ~/unixbench; yum -y install perl-Time-HiRes wget make gcc gcc-c gcc-c++ autoconf time; wget http://byte-unixbench.googlecode.com/files/unixbench-5.1.2.tar.gz; tar zxvf unixbench-5.1.2.tar.gz; cd unixbench-5.1.2; sed -i "s/GRAPHIC_TESTS = defined/#GRAPHIC_TESTS = defined/g" ./Makefile make; ./Run; echo ''; echo ''; echo ''; echo "======= Copy and paste your results to the VPSMARK ======= "; echo ''; echo 'http://blog.itnmg.net/'; echo ''; echo ''; |
CentOS 安装 phpMyAdmin
安装 phpMyAdmin
如果已经将PHP更新到5.2.x，可以自行安装phpMyAdmin最新版3.x。
phpMyAdmin是一款MySQL数据库web化的管理工具。
1 | yum install phpMyAdmin |
现在我们配置下phpMyAdmin。我们改下Apache的配置文件，使的phpMyAdmin不单单是本机访问。 如下所示:
1 | vi /etc/httpd/conf.d/phpMyAdmin.conf |
注释或删除本地ip限制. 如下
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | <Directory /usr/share/phpMyAdmin/> <IfModule mod_authz_core.c> # Apache 2.4 <RequireAny> #Require ip 127.0.0.1 Require ip ::1 </RequireAny> </IfModule> <IfModule !mod_authz_core.c> # Apache 2.2 Order Deny,Allow Deny from All Allow from All Allow from ::1 </IfModule> </Directory> <Directory /usr/share/phpMyAdmin/setup/> //这一段是web配置工具的访问权限,如果不使用,可以不修改. <IfModule mod_authz_core.c> # Apache 2.4 <RequireAny> #Require ip 127.0.0.1 Require ip ::1 </RequireAny> </IfModule> <IfModule !mod_authz_core.c> # Apache 2.2 Order Deny,Allow Deny from All Allow from All Allow from ::1 </IfModule> </Directory> |
然后修改里面的配置文件：
1 | vi /usr/share/phpMyAdmin/config.inc.php |
1 2 | $cfg['blowfish_secret'] = ‘ ‘ //单引号里面随便填一个字符串。 $cfg['Servers'][$i]['auth_type'] = 'cookie'; //这里使用 cookie 作为验证方式. |
重启Apache:
1 | service httpd restart |
然后,你就可以通过 http://domain.com/phpmyadmin/ 访问phpMyAdmin了。
CentOS 安装 VSFTP
配置 FTP 服务
1.安装 vsFTP
1 | yum install vsftpd |
编辑配置文件
1 | vi /etc/vsftpd/vsftpd.conf |
我们这里使用虚拟用户的形式, 配置如下.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | anonymous_enable=NO local_enable=YES write_enable=YES local_umask=022 dirmessage_enable=YES xferlog_enable=YES xferlog_file=/var/log/vsftpd.log connect_from_port_20=YES ftpd_banner=Welcome to My FTP Server ^_^. chroot_local_user=YES ls_recurse_enable=YES listen=YES pam_service_name=vsftpd userlist_enable=NO tcp_wrappers=YES one_process_model=no #以下是手动添加的 pasv_min_port=30000 pasv_max_port=35000 allow_writable_root=YES guest_enable=YES guest_username=root virtual_use_local_privs=YES user_config_dir=/etc/vsftpd/user_conf |
2.生成vsftpd虚拟用户数据库文件：
建立虚拟用户名单文件：
1 | vi /etc/vsftpd/ftpuser.txt |
内容如下：
1 2 3 4 | ftp1 1234 ftp2 5678 |
格式很简单：“一行用户名，一行密码！”。
CentOS 安装 Zend Guard Loader
在 Zend 官网上找到 Zend Guard Loader 的下载页, 找到 Linux 版本的 Zend Guard Loader, 点击下载, 需要登录, 登录后会弹出下载提示, 开始下载, 复制实际下载地址, 用 wget 下载.
1 2 | yum install wget wget http://downloads.zend.com/guard/6.0.0/ZendGuardLoader-70429-PHP-5.4-linux-glibc23-i386.tar.gz |
解压下载的文件
1 | tar zxvf ZendGuardLoader-70429-PHP-5.4-linux-glibc23-i386.tar.gz |
进入 ZendGuardLoader 目录, 查看 README 文档, 按照说明进行安装.
1 2 | cd ZendGuardLoader-php-5.4-linux-glibc23-i386 cat README.txt |
开始安装
复制 php-5.4.x 文件夹下的 ZendGuardLoader.so 到 /usr/lib/httpd/modules 目录或 /etc/httpd/modules 目录, 这两个目录其实是同一个位置.
1 | cp ZendGuardLoader.so /usr/lib/httpd/modules |
编辑 php配置文件.
1 | vi /etc/php.ini |
在 php.ini 文件末尾添加几行配置项.
1 2 3 4 | zend_extension=/usr/lib/httpd/modules/ZendGuardLoader.so zend_loader.enable=1 zend_loader.disable_licensing=0 zend_loader.obfuscation_level_support=3 |
重启 Apache 或 Nginx
1 2 3 4 | service httpd restart service nginx restart service php-fpm restart |
用浏览器打开 phpinfo.php 页面, 在 php 项最下面看到如图所示即完装成功.
CentOS 安装 LNMP VSFTP 服务
Nginx 的支持高并发, 强大的负载均衡, 低资源消耗 使它成为了 Linux web 服务端的首选, 尤其对于小内存的 VPS, 这点更为明显, 使它完胜 Apache.
下面就介绍 LNMP 的安装.
CentOS 安装 MySql
执行下面的命令来安装 MySQL：
1 | yum install mysql mysql-server |
然后启动 MySQL 服务器：
1 | service mysqld start |
运行下面的命令来为 root 用户设置一个密码（否则的话任何人都可以访问你的MySQL数据库！）：
1 | mysqladmin -u root -p password 12345678 |
Enter password: 输入root当前密码以确认修改，一般root初始密码为空（上面的12345678为你想要的密码）
C# 使用 Socket 实现 http 协议全功能版
有人说用 Socket 请求 http 服务效率要比 HttpWebRequest 高很多, 但是又没有提供源码或者对比测试结果. 我对此很好奇, 到底能差多少? 所以决定自己写个类实现 Socket 请求 http 的功能.
