htpasswd建立和更新存储用户名、密码的文本文件， 用于对HTTP用户的basic认证。
参数：
-c 创建passwdfile.如果passwdfile 已经存在,那么它会重新写入并删去原有内容.
-n 不更新passwordfile，直接显示密码
-m 使用MD5加密（默认）
-d 使用CRYPT加密（默认）
-p 使用普通文本格式的密码
-s 使用SHA加密
-b 命令行中一并输入用户名和密码而不是根据提示输入密码，可以看见明文，不需要交互
-D 删除指定的用户

# htpasswd -bc .access username password  #在当前目录生成.access文件，用户名username，密码：password，默认采用MD5加密方式。 
# htpasswd -b .access test 123456   #在原有密码文件中增加下一个用户
# htpasswd -nb test 123456  #不更新.access文件，只在屏幕上输出用户名和经过加密后的密码。 
# htpasswd -D .access test  #利用htpasswd命令删除用户名和密码

-----------------------------------
# htpasswd -c -m /etc/httpd/.htpasswd admin         #（admin是登陆时的用户名）
New password:               #输入密码

#MaxRequestWorkers设置了允许同时的最大接入请求数量。任何超过MaxRequestWorkers限制的请求将进入等候队列，在apache2.3.1以前的版本MaxRequestWorkers被称为MaxClients，旧的名字仍旧被支持。
MaxConnectionsPerChild   500
#设置的是每个子进程可处理的请求数。每个子进程在处理了“MaxConnectionsPerChild”个请求后将自动销毁。0意味着无限，即子进程永不销毁。虽然缺省设为0可以使每个子进程处理更多的请求，但如果设成非零值也有两点重要的好处：1、可防止意外的内存泄漏。2、在服务器负载下降的时侯会自动减少子进程数。因此，可根据服务器的负载来调整这个值。在Apache2.3.9之前称之为MaxRequestsPerChild。

如何查看Apache的工作模式呢？可以使用httpd -V 命令查看，另外使用httpd -l 也可以查看到

1.[root@www ~]# vi /usr/local/http-2.4.23/conf/extra/httpd-mpm.conf
2.[root@www ~]# vi /usr/local/http-2.4.23/conf/httpd.conf
LoadModule mpm_prefork_module modules/mod_mpm_prefork.so
Include conf/extra/httpd-mpm.conf
3.重启httpd服务

step 1: 
　　#sudo dd if=/dev/zero of=/home/swap bs=64M count=16 
　　注释：of=/home/swap,放置swap的空间; count的大小就是增加的swap空间的大小，64M就是块大小，这里是64MB，所以总共空间就是bs*count=1024MB.这里分配空间的时候需要一点时间，等待执行完毕。  
step 2: 
　　# sudo mkswap /home/swap (可能会提示warning: don’t erase bootbits sectorson whole disk. Use -f to force，不用理会) 
　　注释：把刚才空间格式化成swap各式 
step 3: 
　　#sudo swapon /home/swap 
　　注释：使刚才创建的swap空间 
step 4:执行你相关的操作，如make 

关闭: 
step 1:sudo swapoff /home/swap 
step 2:sudo rm /home/swap

SIEGE 4.0.2
Usage: siege [options]
       siege [options] URL
       siege -g URL
-C, --config ：查看siege当前的配置信息
-V, --version：版权说明信息
-c, --concurrent=NUM：并行启动（访问）用户数，默认是10
-t, --time=NUMm：压力测试时间，比如-t5表示持续时间是5分钟
-b, --benchmark：基准测试，请求之间没有延迟。
-g, --get get方式请求
-d, --delay=NUM 时间延迟，每个请求之间的延迟时间
-i, --internet 模拟用户，随机点击的URL。
-r, --reps=NUM：每个连接发出的请求数量，这个与t有些类似，所以设置了这个值就不需要设置t了，反之亦然。
-f, --file=FILE：对应一个文件，这个文件里每一行为一个URL链接，格式如：
-m, --mark="text"  在日志里标记的字符串标识
-H, --header="text" 在Header里增加的字符串标识
-A, --user-agent="text" 在user-agent里增加的字符串标识
