Linux under Compile and install Apache HTTPD 2.4

Apache is the world's most used Web server software. It can run on almost all widely used computer platforms and is one of the most popular Web server-side software due to its widespread use across platforms and security. The current Apache version is 2.4, this article mainly describes the installation of Apache httpd based on the CentOS 6.5 source method.

First, the advantages of compiling and installing

源码的编译安装一般由3个步骤组成：    配置(configure)，通常依赖gcc编译器，binutils，glibc。配置软件特性，检查编译环境，生成 Makefile文件    编译(make)    安装(make install)优势    自定义软件功能    优化编译参数，提高性能    解决不必要的软件间依赖    方便清理与卸载configure是一个可执行脚本，它有很多选项，在待安装的源码路径下使用命令./configure –-help输出详细的选项列表。常用的选项--prefix    该选项是配置安装的路径，如果不配置该选项，安装后可执行文件默认放在/usr /local/bin，    库文件默认放在/usr/local/lib，配置文件默认放在/usr/local/etc，其它的资源文件放在/usr /local/share    如果配置--prefix，如： ./configure --prefix=/usr/local/test    则可以把所有资源文件放在/usr/local/test的路径中，不会杂乱。    用了—prefix选项的另一个好处是卸载软件或移植软件。    当某个安装的软件不再需要时，只须简单的删除该安装目录，就可以把软件卸载得干干净净；    移植软件只需拷贝整个目录到另外一个机器即可（相同的操作系统）。    当然要卸载程序，也可以在原来的make目录下用一次make uninstall，但前提是make文件指定过uninstall。

Second, the httpd version

版本：    httpd-1.3    httpd-2.0    httpd-2.2    httpd-2.4

V. Configuration http2.4 start and stop

1, modify the port number to modify the port number so that2.2The version uses different ports and can be run at the same time, modified as follows# cat/etc/httpd24/httpd.conf |grep Listen |grep-v ^#Listen80802, Start and stop#/usr/local/apache/bin/apachectl Start    # Netstat-nltp|grepTcp0      0:::8080:::* LISTEN17365/httpd#/USR/LOCAL/APACHE/BIN/APACHECTL StatusNot Found the requested Url/server-status was notFound onThis server. By modifying the httpd.conf, add the following configuration# grep Server-stat/etc/httpd24/httpd.conf-a5<Location/server-status> SetHandler Server-status# Order Deny,allow        # Deny from allAllow from 192.168.. 157 192.168..
