Linux系统安装Apache 2.4.6

Apache简介

 

        Apache HTTP Server（简称Apache）是Apache软件基金会的一个开放源码的网页服务器，可以在大多数计算机操作系统中运行，由于其多平台和安全性被广泛使用，是最流行的Web服务器端软件之一。它快速、可靠并且可通过简单的API扩展，将Perl/Python等解释器编译到服务器中。关于更多Apache的介绍，可以参考百科“http://baike.baidu.com/view/28283.htm或官网http://www.apache.org/ 或 http://httpd.apache.org/的介绍

Apache安装要求

下面是官方文档的要求，必须安装APR、APR-Util、PCRE，gcc-c++等包，文档URL地址http://httpd.apache.org/docs/2.4/install.html

 

Requirements

The following requirements exist for building Apache httpd:

APR and APR-Util

Make sure you have APR and APR-Util already installed on your system. If you don't, or prefer to not use the system-provided versions, download the latest versions of both APR and APR-Util from Apache APR, unpack them into ./srclib/apr and ./srclib/apr-util (be sure the directory names do not have version numbers; for example, the APR distribution must be under ./srclib/apr/) and use ./configure's --with-included-apr option. On some platforms, you may have to install the corresponding -dev packages to allow httpd to build against your installed copy of APR and APR-Util.

Perl-Compatible Regular Expressions Library (PCRE)

This library is required but not longer bundled with httpd. Download the source code from http://www.pcre.org, or install a Port or Package. If your build system can't find the pcre-config script installed by the PCRE build, point to it using the --with-pcre parameter. On some platforms, you may have to install the corresponding -dev package to allow httpd to build against your installed copy of PCRE.

Disk Space

Make sure you have at least 50 MB of temporary free disk space available. After installation the server occupies approximately 10 MB of disk space. The actual disk space requirements will vary considerably based on your chosen configuration options, any third-party modules, and, of course, the size of the web site or sites that you have on the server.

ANSI-C Compiler and Build System

Make sure you have an ANSI-C compiler installed. The GNU C compiler (GCC) from the Free Software Foundation (FSF) is recommended. If you don't have GCC then at least make sure your vendor's compiler is ANSI compliant. In addition, your PATH must contain basic build tools such as make.

Accurate time keeping

Elements of the HTTP protocol are expressed as the time of day. So, it's time to investigate setting some time synchronization facility on your system. Usually thentpdate or xntpd programs are used for this purpose which are based on the Network Time Protocol (NTP). See the NTP homepage for more details about NTP software and public time servers.

Perl 5 [OPTIONAL]

For some of the support scripts like apxs or dbmmanage (which are written in Perl) the Perl 5 interpreter is required (versions 5.003 or newer are sufficient). If you have multiple Perl interpreters (for example, a systemwide install of Perl 4, and your own install of Perl 5), you are advised to use the --with-perl option (see below) to make sure the correct one is used by configure. If no Perl 5 interpreter is found by the configure script, you will not be able to use the affected support scripts. Of course, you will still be able to build and use Apache httpd.

 

Apache安装过程

 

Step 1：安装包gcc或gcc-c++

[root@getlnx05 pcre-8.33]# yum list gcc-c++

Loaded plugins: product-id, security, subscription-manager

Updating Red Hat repositories.

Available Packages

gcc-c++.x86_64                                                               4.1.2-51.el5                                                                rhel-debuginfo

[root@getlnx05 pcre-8.33]# yum list gcc

Loaded plugins: product-id, security, subscription-manager

Updating Red Hat repositories.

Installed Packages

gcc.x86_64                                                                    4.1.2-51.el5                                                                    installed

[root@getlnx05 pcre-8.33]# rpm -q gcc

gcc-4.1.2-51.el5

从上面可见gcc包已经安装，缺少gcc-c++包，那么接下来安装包gcc-c++,如果此处不安装该包，后面安装过程中会报错

[root@getlnx05 pcre-8.33]#yum install  gcc-c++

 

Step 2：安装包APR和APR-Util

[root@getlnx05 kerry]# ls apr*

apr-1.4.8.tar.gz  apr-util-1.5.2.tar.gz

[root@getlnx05 kerry]#

[root@getlnx05 kerry]# tar -zxf apr-1.4.8.tar.gz

[root@getlnx05 kerry]# cd apr-1.4.8

[root@getlnx05 apr-1.4.8]# ls

新建目录/usr/local/apr，用作安装目录：

[root@getlnx05 apr-1.4.8]# mkdir /usr/local/apr

[root@getlnx05 apr-1.4.8]# ./configure --prefix=/usr/local/apr

[root@getlnx05 apr-1.4.8]# make

[root@getlnx05 apr-1.4.8]# make install

安装完成后，可以验证一下

[ root@getlnx05 apr]# ls -lrt

total 32

drwxr-xr-x 3 root root 4096 Aug 15 06:57 include

drwxr-xr-x 3 root root 4096 Aug 15 06:57 lib

drwxr-xr-x 2 root root 4096 Aug 15 06:57 build-1

drwxr-xr-x 2 root root 4096 Aug 15 06:57 bin

[root@getlnx05 kerry]# mkdir /usr/local/apr-util

[root@getlnx05 kerry]# tar -zxf apr-util-1.5.2.tar.gz

[root@getlnx05 kerry]# cd apr-util-1.5.2

[root@getlnx05 apr-util-1.5.2]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/bin/apr-1-config

[root@getlnx05 apr-util-1.5.2]# make

[root@getlnx05 apr-util-1.5.2]# make install

 

Step 3：安装包PRCE

[root@getlnx05 kerry]# unzip pcre-8.33.zip

[root@getlnx05 kerry]# cd pcre-8.33

[root@getlnx05 kerry]#mkdir /usr/local/pcre

[root@getlnx05 pcre-8.33]# ./configure --prefix= /usr/local/pcre--with-apr=/usr/local/apr/bin/apr-1-config

[root@getlnx05 pcre-8.33]# make

[root@getlnx05 pcre-8.33]# make install

 

Step 4：安装Apache Http Server

[root@getlnx05 kerry]# tar zxvf httpd-2.4.6.tar.gz

[root@getlnx05  kerry]#cd httpd-2.4.6

[root@getlnx05 httpd-2.4.6]# ./configure --prefix=/usr/local/apache --with-pcre=/usr/local/pcre --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util

[root@getlnx05 httpd-2.4.6]#make

[root@getlnx05 httpd-2.4.6]#make install

Step 5：启动Apache服务

[root@getlnx05 httpd-2.4.6]#  /usr/local/apache/bin/apachectl start

用浏览器访问http://localhost时提示It works!

 

 

Apache安装问题锦集

 

问题1：缺少包gcc-c++导致安装包apr-util不通过

 

[root@getlnx05 kerry]# unzip pcre-8.33.zip

[root@getlnx05 kerry]# cd pcre-8.33

[root@getlnx05 pcre-8.33]# ./configure --prefix=/usr/local/apr-util -with-apr=/usr/local/apr/bin/apr-1-config

一般出现这个错误是因为没有安装包gcc-c++,可以通过如下命令检查，

[root@getlnx05 pcre-8.33]# yum list gcc-c++

Loaded plugins: product-id, security, subscription-manager

Updating Red Hat repositories.

Available Packages

gcc-c++.x86_64                                                               4.1.2-51.el5                                                                rhel-debuginfo

[root@getlnx05 pcre-8.33]# yum list gcc

Loaded plugins: product-id, security, subscription-manager

Updating Red Hat repositories.

Installed Packages

gcc.x86_64                                                                    4.1.2-51.el5                                                                    installed

[root@getlnx05 pcre-8.33]# rpm -q gcc

gcc-4.1.2-51.el5

[root@getlnx05 pcre-8.33]# rpm -q gcc-c++

 

问题2：checking for APR-util... configure: error: the --with-apr-util parameter is incorrect

[root@getlnx05 httpd-2.4.6]#

一般是由于APR-util没有安装成功，可以通过验证该目录是否为空来判断，因为你有时候执行了make，忘了执行make isntall命令有可能导致这个错误。

[root@getlnx05 apr]# cd /usr/local/apr-util

[root@getlnx05 apr-util]# ls

 

问题3：没有指定PCRE参数
