# Description: PHP-FastCgi start script from http://blog.kovyrin.net/2006/05/30/nginx-php-fastcgi-howto/
#
# Author: Alexey Kovyrin http://blog.kovyrin.net
# Comments by: Geoffrey Grosenbach http://topfunky.com
#
# This script is started once and receives PHP requests from Nginx for 
# all apps. The Nginx config passes the full path to the script being requested, so
# only one fastcgi runner is needed for all apps, virtual hosts, etc.
#
# See also the init.d script for starting this on boot.
#
# To install PHP, I had to also compile the following:
#
#   * http://www.gnu.org/software/m4/
#   * http://flex.sourceforge.net/
#   * http://php.net/ with './configure --prefix=/usr/local --enable-fastcgi'

## ABSOLUTE path to the PHP binary
PHPFCGI="/usr/local/bin/php"

## tcp-port to bind on
FCGIPORT="9000"

## IP to bind on
FCGIADDR="127.0.0.1"

## number of PHP children to spawn
PHP_FCGI_CHILDREN=5

## number of request before php-process will be restarted
PHP_FCGI_MAX_REQUESTS=1000

# allowed environment variables sperated by spaces
ALLOWED_ENV="PATH USER"

## if this script is run as root switch to the following user
USERID=deploy

################## no config below this line

if test x$PHP_FCGI_CHILDREN = x; then
  PHP_FCGI_CHILDREN=5
fi

ALLOWED_ENV="$ALLOWED_ENV PHP_FCGI_CHILDREN"
ALLOWED_ENV="$ALLOWED_ENV PHP_FCGI_MAX_REQUESTS"
ALLOWED_ENV="$ALLOWED_ENV FCGI_WEB_SERVER_ADDRS"

if test x$UID = x0; then
  EX="/bin/su -m -c \"$PHPFCGI -q -b $FCGIADDR:$FCGIPORT\" $USERID"
else
  EX="$PHPFCGI -b $FCGIADDR:$FCGIPORT"
fi

echo $EX

# copy the allowed environment variables
E=

for i in $ALLOWED_ENV; do
  E="$E $i=${!i}"
done

# clean environment and set up a new one
nohup env - $E sh -c "$EX" &> /dev/null &

find

By 清茶 on February 5, 2008 2:57 PM |
我们经常要在日常的工作中查找文件，要说linux下最强大的文件查找工具，非find莫属。find可以从文件名、读取修改时间、大小、类型等等来筛选文件，可以完成日常几乎所有的查找需求。

来看一个简单的例子：

find /tmp/ -name 'galeki*'

意思就是在/tmp目录下找出以"galeki"开头的文件，-name指出是对文件名进行筛选，是不是很简单明了？除了文件名，find还有更强大的筛选条件：
1.时间：
参数     意义
-atime n     上一次存取时间在n*24小时前以内的文件
-ctime n     上一次状态改变在n*24小时前以内的文件
-mtime n     上一次修改时间在n*24小时前以内的文件
-newer file     比file所指的文件还要新的文件

2.大小：
参数     意义
-size n[bkMG]     大小为n（b为比特，k为KB，M为MB，G为GB）的文件

3.所有者：
参数     意义
-user name     所有者用户名称是name的文件
-group name     所有者用户组群名称是name的文件

例子：
find /tmp/ -name 'sess*' -mtime 1   #在/tmp目录下找到所有以'sess'开头、并且在一个小时以内修改过的文件
find ./ -name '*.zip' -size 546k       #在当前目录下找到所有546KB的zip压缩包文件
find /tmp/ -user 'galeki'               #在/tmp目录下找到所有所有者为galeki的文件

另外，还可以用"+"、"-"来进一步修饰时间和大小的条件：
find src/ -mtime +2            #找出src目录下上一次修改时间在2天以前的文件
find download/ -size +50M    #在download目录下找出大于50M的文件

光找出文件还不够，我们还要对找出的文件进行处理才有意义，一般来讲可以把find的查找结果传递给其他的命令做进一步处理。find本身也提供了许多处理动作的选项。
常用的处理动作：
参数     意义
-print
    打印出找出文件的完整地址，一个文件一行
-delete
    删除找出的文件
-exec command {} \;
    对每一个找到的文件执行command命令，并用文件替换"{}"，"\;"是固定的结束符。

例子：
find /tmp/ -ctime +7 -delete            #删除/tmp目录下一周以前创建的文件
find ./ -name '*.unk' -exec file {} \;   #找出当前文件夹下后缀是unk的文件，并用file命令显示每个文件的文件类型

以上只是find的一些简单的用法.

xcache ZendOptimizer

By 清茶 on February 4, 2008 1:19 AM |
之前一直是eaccelerator + ZendOptimizer的组合
现在换成了xcache+ZendOptimizer, 按照其安装方法,没有什么难度,尤其在BSD上,还是通过ports来安装
不过在重启php就出现问题了,总是报错.......
最终的解决方法是,把xcache.ini里
[xcache-common]
;; install as zend extension (recommended, but not working yet)
;; zend_extension = /usr/local/lib/php/20060613/xcache.so
; zend_extension_ts = /usr/local/lib/php/20060613/xcache.so
;; or install as extension
;;extension = xcache.so
关于用zend 扩展模式的两个加入到php.ini里在ZendOptimizer之前即可
