ECstore

ECstore采用pathinfo做资源定位，所以要求$_SERVER环境变量中必须要有PATHINFO或则ORGI_PATHINFO
一般在apache或者iis下都没有什么问题，但是在nginx下需要对配置文件做一些设置才可以
这些设置主要是在php fast cgi的配置文件中，设置代码为


set $real_script_name $fastcgi_script_name;
if ($fastcgi_script_name ~ "(.+?.php)(/.+)") {
set $real_script_name $1;
set $path_info $2;
}

fastcgi_param SCRIPT_FILENAME $document_root$real_script_name;
fastcgi_param SCRIPT_NAME $real_script_name;
fastcgi_param PATH_INFO $path_info;

可参考我的nginx配置

利用VPS+Chrome SwitchySharp插件 进行翻墙

vps

一般新买的VPS都会装好SSH服务，并提供了root来远程管理的，我用的vps装的ubuntu系统，ssh己装好。要用ssh代理来翻墙也很容易，为了避免和我的管理账户冲突，我新建了一个ssh用户，并且禁用了该用户的shell。以下是相关命令：


$groupadd sshfq (增加组sshfq）

$useradd -d /home/sshfq -m -g sshfq -s /bin/false sshfq (增加用户sshfq创建同名目录并属于组sshfq并禁止shell)

$passwd sshfq (修改sshfq密码）

这样服务器端就设置完成了。

如果要修改服务器监听ssh的端口，可 运行如下命令：


ssh -qTfnN -D  端口  sshfq@你VPS的IP

接下来Chrome安装好SwitchySharp进行以下配置即可

Tips:

ssh -qTfNn用于建立纯端口转发用途的ssh连接，参数具体含义如下：

  • -q: quiet模式，忽视大部分的警告和诊断信息（比如端口转发时的各种连接错误）
  • -T: 禁用tty分配(pseudo-terminal allocation)
  • -f: 登录成功后即转为后台任务执行
  • -N: 不执行远程命令（专门做端口转发）
  • -n: 重定向stdin为/dev/null，用于配合-f后台任务

运行

sudo launchctl load -w /Library/LaunchDaemons/org.macports.phpfcgi.plist

运行

sudo lsof -i:80

和

sudo lsof -i:9000

检查nginx和fastcgi是否分别正常监听80和9000端口
如果安装php扩展，安装后重启fastcgi即可

sudo killall php-cgi53
sudo php-cgi53 -b 127.0.0.1:9000  &

在未使用memcache锁时，使用ab进行并发测试，会有很大几率出现重复数据的插入。
在使用memcache锁后，用ab进行并发测试，已经解决了上述问题

php过滤html的函数：strip_tags(string) 这样就可以过滤掉所有的html标签了。
如果想过滤掉除了<img src=””>之外的所有html标签，则可以这样写：strip_tags(string,”<img>”);
过滤除了<img src=””><p>xxx</p><b></b>之外的所有html标签，则可以这样写：strip_tags(string,”<img><p><b>”);
