原料：

    鸡，蒜，姜，葱，香菇

调味料：

    盐，老抽，糖，鸡精

做法：

1、将鸡斩成小块，蒜去皮拍烂，姜拍烂，葱切成段，香菇对切；

2、锅里下油，鸡块放入锅中，炒至颜色变白后加水600-700毫升；

3、锅中加入1汤匙酱油，2汤匙糖，少许盐、鸡精；

4、大火煮开之后，小火炖煮至水基本上收干即可。

原料：

鸭子  半只  啤酒  一罐  姜  4小块  冰糖  适量

调味料：

盐  老抽

做法：

1  把鸭子剁块，锅中加水烧开，放入鸭子煮几分钟，捞出沥干水分

 2  炒锅加油烧热，放入鸭块和姜翻炒，盖上锅盖闷一会，逼出水分打开盖子把鸭子炒干

 3  转小火加老抽冰糖和盐炒匀，开大火加入啤酒，把汁烧的浓稠即可

切的丁小了点,难看点,味道还不错。

mysql安装在/usr/local/下

perl Makefile.PL --mysql_config=/usr/local/mysql/bin/mysql_config --testuser=root --testpassword=s3kr1t
make
make test
出现以下错误:

升级Test-Simple

make test
继续出错
Can't load '/usr/local/DBD-mysql-4.008/blib/arch/auto/DBD/mysql/mysql.so' for module DBD::mysql: libmysqlclient.so.16:

make test

测试顺利通过

mod_perl下载地址:
http://perl.apache.org/dist/mod_perl-2.0-current.tar.gz

Apache2::Request
http://search.cpan.org/~joesuf/libapreq2-2.12/glue/perl/lib/Apache2/Request.pm
http://search.cpan.org/CPAN/authors/id/J/JO/JOESUF/libapreq2-2.12.tar.gz



在/home/modperl下安装mod_perl和libapreq2

cd /home/modeperl
tar zxvf mod_perl-2.0-current.tar.gz
cd mod_perl-2.0.4/
perl Makefile.PL MP_APXS=/usr/local/apache2/bin/apxs
make
make test
make install

编译libapreq2 for apache2
cd /home/modeperl
tar zxvf libapreq2-2.12.tar.gz
cd libapreq2-2.12
./configure --with-expat=/usr/local/apr-util/ --with-apache2-apxs=/usr/local/apache2/bin/apxs
make
make test
make install

配置httpd.conf
LoadModule perl_module          modules/mod_perl.so
LoadModule apreq_module         modules/mod_apreq2.so


再安装Apache2::Request模块
perl Make.PL  --with-expat=/usr/local/apr-util/ --with-apache2-apxs=/usr/local/apache2/bin/apxs
make
make test
make install

man proc得到以下解释：
       /proc/loadavg
              The  load  average  numbers  give the number of jobs in the run queue (state R) or waiting for disk I/O (state D) averaged over 1, 5, and 15 minutes.  They are the
              same as the load average numbers given by uptime(1) and other programs.
使用ps找出这两种状态的进程数
ps aux |grep ' [D|R] '|wc -l
上面所获得的值和uptime得到的值基本相同。
如果状态为R的进程数很多，说明CPU瓶颈，如果状态为D的进程很多，说明IO出现瓶颈。

    一般来说只要每个CPU的当前活动进程数不大于3那么系统的性能就是良好的，如果每个CPU的任务数大于5，那么就表示这台机器的性能有严重问题。对于上面的例子来说，假设系统有两个CPU，那么其每个CPU的当前任务数为：8.13/2=4.065。这表示该系统的性能是可以接受的。

单进程打开文件数上限设置
编缉文件/etc/security/limits.conf

* - nofile 65536

此文件还可以对特定的用户进行限制

如果在/etc/rc.local中运行程序，涉及到文件数的限制
在运行命令前添加：

ulimit -SHn 65536

查看单进程打开文件数上限:

ulimit -n


所有进程打开文件数的限制
/proc/sys/fs/file-max


同时要更改

/proc/sys/fs/inode-max

此值为file-max的3-4倍，具本描述查看man文档

man proc

启动"组策略"：开始-运行-gpedit.msc-确定

左侧"用户配置"-管理模板-windows组件-windows资源管理器

右侧双击第三项：  从"工具"菜单删除"文件夹选项"菜单

选中"已禁用"-确定

    dmidecode  is a tool for dumping a computer's DMI (some say SMBIOS) table contents in a human-readable format. This table contains a description of the system's hardware components, as well as other  useful  pieces  of  information such as serial numbers and BIOS revision. Thanks to this table, you can retrieve this information without having to probe for the actual hardware.  While this is a good point in terms of report speed and safeness, this  also  makes the presented information possibly unreliable.

命令行工具：

将其存放至
