APACHE(3)
3.21 Port 指令
语法: Port 数字
预设: Port 80
用於: server config
状态: 核心
这个 Port 指令设定服务器监听的网路端口号。数字是 0 到 65535 的
一个数目;某些端口号(特别是低於 1024 的)保留给特殊的协定。参阅
/etc/services 里定义的一些端口的列表;标准 http 协定使用 80 端口。
Port 80 是 Unix's 的一个特别端口。所有低於 1024 的端口号都是保留给
系统使用的,例如,一般使用者(non-root)不能使用它们;取而代之的
是他们可以使用较高的端口号。
要使用 80 端口你必须以 root 帐号启动服务器。在连接到该端口後,接受
请求之前,阿帕奇将会切换为藉由 User 指令所设定权限较低的使用者
身分。
如果你不能使用 80 端口,选择任何其它没有使用到的端口。非 root 使用
者必须选择高於 1023 的端口号,像是 8000 。
安全: 如果你是以 root 启动服务器,确定不要把 User 设为 root 。
如果你以 root 身分处理连线的话,你的站台可能会暴露在攻击下。
3.22 require 指令
语法: require 项目名称 项目 项目 ...
用於: directory, .htaccess
需求: AuthConfig
状态: 核心
这个指令选择经过验认可以存取目录的使用者。允许使用的语法是:
。require user 使用者辨识码 使用者辨识码 ...
只有注明的使用者能存取该目录。
。require group 群组名称 群组名称 ...
只有在注明群组里的使用者能存取该目录。
。require valid-user
所有合法的使用者都可以存取该目录。
如果 require 出现在 节段里,那麽它会限制所注明的存取
方式,否则它会限制所有的存取方式。例如:
AuthType Basic
AuthName somedomain
AuthUserFile /web/users
AuthGroupFile /web/group
Limit
require group admin
Require 必须藉由 AuthName 以及 AuthType 这些指令,以及配合像是
AuthUserFile 以及 AuthGroupFile 指令(用来定义使用者与群组)
以便正确运作。
3.23 ResourceConfig 指令
语法: ResourceConfig 文件名称
预设: ResourceConfig conf/srm.conf
用於: server config, virtual host
状态: 核心
此服务器读取 httpd.conf 文件之後将会继续读取这个文件以取得更多

This article discusses how to improve Hadoop data processing efficiency on Debian systems. Optimization strategies cover hardware upgrades, operating system parameter adjustments, Hadoop configuration modifications, and the use of efficient algorithms and tools. 1. Hardware resource strengthening ensures that all nodes have consistent hardware configurations, especially paying attention to CPU, memory and network equipment performance. Choosing high-performance hardware components is essential to improve overall processing speed. 2. Operating system tunes file descriptors and network connections: Modify the /etc/security/limits.conf file to increase the upper limit of file descriptors and network connections allowed to be opened at the same time by the system. JVM parameter adjustment: Adjust in hadoop-env.sh file
