http://www.lsproc.com/blog/use_ob_flush_on_nginx_fastcgi/

Nginx与php-cgi是两个独立的程序，通过TCP或Unix套接字通信，不像Apache那样是集成在一起的。所以，Nginx有fastcgi 缓冲区，数据超出缓冲区大小、或程序执行完，才会将内容输出到客户端。如果要使用ob_flush，不能开启gzip压缩输出。

nginx.conf:

fastcgi_buffer_size 4k;
fastcgi_buffers 8 4k;
gzip off;

php.ini:

output_buffering = Off

<?php
set_time_limit(0);
ob_end_clean();
ob_implicit_flush(1);

for($i = 0; $i < 10; $i++)
{
    echo $i . "<br />\n";
    echo str_repeat('', 1024*4);
    sleep(1);
}

其中 echo str_repeat('', 1024*4);
使得fastcgi_buffer_size 4k; 的缓冲区满，从而输出内容到浏览器

首先你需要一个中文字体
如simsun 等
将它放进 /usr/share/fonts目录中

然后执行下面的命令刷新字体缓存

fc-cache -f -v

然后再cacti 中设置 默认字体的路径为你使用的中文字体的路径

测试发现, 字体只能放到系统字体路径当中, 并要刷新字体缓存

linux下:

vim ~/.subversion/config

windows下

%APPDATA%\Subversion\config

编辑此文件

[auto-props]
*.html = svn:keywords=Id Reversion Date Author
*.php = svn:keywords=Id Reversion Date Author
*.css = svn:keywords=Id Reversion Date Author
*.js = svn:keywords=Id Reversion Date Author

并启用auto-props

[miscellany]
enable-auto-props = yes

这样在 svn add 和 svn import 时就会自动添加keywords

现有的源代码还是没有这个属性，我们得批量的设置一下，一行命令就搞定了（比如我们的目标是当前目录下的所有python源代码文件）：

find ./ -type f -name "*.py" | xargs svn propset svn:keywords "Id Reversion Date Author"

使用OpenSSL生成证书

1、生成RSA密钥的方法

openssl genrsa -des3 -out privkey.pem 2048
这个命令会生成一个2048位的密钥，同时有一个des3方法加密的密码，如果你不想要每次都输入密码，可以改成：
openssl genrsa -out privkey.pem 2048
建议用2048位密钥，少于此可能会不安全或很快将不安全。

2、生成一个证书请求
openssl req -new -key privkey.pem -out cert.csr
这个命令将会生成一个证书请求，当然，用到了前面生成的密钥privkey.pem文件
这里将生成一个新的文件cert.csr，即一个证书请求文件，你可以拿着这个文件去数字证书颁发机构（即CA）申请一个数字证书。CA会给你一个新的文件cacert.pem，那才是你的数字证书。

如果是自己做测试，那么证书的申请机构和颁发机构都是自己。就可以用下面这个命令来生成证书：
openssl req -new -x509 -key privkey.pem -out cacert.pem -days 1095
这个命令将用上面生成的密钥privkey.pem生成一个数字证书cacert.pem

配置nginx

server
{
    listen       443;
    ssl on;
    ssl_certificate  /var/www/sslkey/cacert.pem;
    ssl_certificate_key /var/www/sslkey/privkey.pem;
    server_name  192.168.1.1;
    index index.html index.htm index.php;
    root  /var/www/test;

    .....
    ...
}
