【CentOS基礎(chǔ)篇】之編譯安裝httpd

程序包編譯安裝

在linux中,程序的安裝分為rpm安裝、yum安裝和編譯安裝,rpm包和yum包在制作過程中已經(jīng)規(guī)劃好了安裝的路徑,相對普通用戶來說,這種方式相對于便捷,但是只能用在匹配的系統(tǒng)版本上,定義不同的安裝方式。很多軟件使用源碼發(fā)布,以便于應(yīng)用在不同的平臺上。用戶在編譯源碼的時候,生成適用于當(dāng)前操作系統(tǒng)的二進(jìn)制程序。linux有現(xiàn)成的編譯工具,可以批量的,自動的幫我們把成千上萬的源代碼按規(guī)則生成二進(jìn)制。這個工具叫做make(項(xiàng)目管理器),針對于c語言和c++。

本文章所用系統(tǒng)為CentOS 7,httpd源碼為httpd-2.4.27.tar.bz2

準(zhǔn)備工作:安裝開發(fā)包組

在程序的編譯安裝之前,先安裝好開發(fā)包組,執(zhí)行命令yum groupinstall "Development tools"(安裝過程過長,截取部分展示)

[root@centos7 /usr/local/src/httpd-2.4.27]#yum groupinstall "Development tools"

準(zhǔn)備工作:安裝Apache

因?yàn)榘惭bhttpd必須用到apache,在這里提前按住Apache,執(zhí)行命令yum install apr-util-devel

準(zhǔn)備工作:安裝pcre

pcre是通用的正則表達(dá)式引擎,在很多軟件中都可以使用,是必要安裝的組件之一,執(zhí)行命令yum install pcre-devel

下載httpd源碼并上傳至centos虛擬機(jī)并解壓

首先下載我們所需要的httpd源碼,這里推薦下載網(wǎng)址http://apache.fayea.com/httpd/


在這里我們需要用一個工具WinSCP,把我們已經(jīng)下載的httpd-2.4.27.tar.bz2上傳至CentOS 7虛擬機(jī)里。
使用XShell/CRT遠(yuǎn)程連接時,直接使用rz命令向Centos系統(tǒng)上傳文件
第一步:配置WinSCP客戶端,連接到CentOS 7

第二步:找到你下載在windows系統(tǒng)下的源碼包,復(fù)制進(jìn)CentOS 7系統(tǒng)里,在linux中,有一個專門放置源碼包的目錄 /usr/local/src/,推薦源碼包統(tǒng)一放置在此文件夾

第三步:在CentOS 7中檢查是否上傳完成

[root@centos7 ~]#cd /usr/local/src/ 
[root@centos7 /usr/local/src]#ll  
total 6376  
-rw-r--r--. 1 root root 6527394 Jul 31 09:55 httpd-2.4.27.tar.bz2 

第四步:用tar命令解壓已上傳的httpd源碼包,在這里已經(jīng)可以看到解壓后的httpd-2.4.27文件夾

[root@centos7 /usr/local/src]#tar xvf httpd-2.4.27.tar.bz2 
httpd-2.4.27/
httpd-2.4.27/.deps
httpd-2.4.27/.gdbinit
httpd-2.4.27/ABOUT_APACHE
httpd-2.4.27/acinclude.m4
httpd-2.4.27/ap.d
httpd-2.4.27/Apache-apr2.dsw
......
[root@centos7 /usr/local/src]#ll
total 6380
drwxr-xr-x. 11  501 games    4096 Jul  7 01:38 httpd-2.4.27

                          Apache HTTP Server

  What is it?
  -----------

  The Apache HTTP Server is a powerful and flexible HTTP/1.1 compliant
  web server.  Originally designed as a replacement for the NCSA HTTP
  Server, it has grown to be the most popular web server on the
  Internet.  As a project of the Apache Software Foundation, the
  developers aim to collaboratively develop and maintain a robust,
  commercial-grade, standards-based server with freely available
  source code.

  The Latest Version
  ------------------

  Details of the latest version can be found on the Apache HTTP
  server project page under http://httpd.apache.org/.

  Documentation
  -------------

  The documentation available as of the date of this release is
  included in HTML format in the docs/manual/ directory.  The most
  up-to-date documentation can be found at
  http://httpd.apache.org/docs/2.4/.

 APACHE INSTALLATION OVERVIEW

 Quick Start - Unix
 ------------------

 For complete installation documentation, see [ht]docs/manual/install.html or
 http://httpd.apache.org/docs/2.4/install.html

    $ ./configure --prefix=PREFIX
    $ make
    $ make install
    $ PREFIX/bin/apachectl start

    NOTES: * Replace PREFIX with the filesystem path under which 
             Apache should be installed.  A typical installation
             might use "/usr/local/apache2" for PREFIX (without the
             quotes).

           * Consider if you want to use a previously installed APR and
             APR-Util (such as those provided with many OSes) or if you
             need to use the APR and APR-Util from the apr.apache.org
             project. If the latter, download the latest versions and
             unpack them to ./srclib/apr and ./srclib/apr-util (no
             version numbers in the directory names) and use
             ./configure's --with-included-apr option. This is required
             if you don't have the compiler which the system APR was
             built with.  It can also be advantageous if you are a
             developer who will be linking your code with Apache or using
             a debugger to step through server code, as it removes the
             possibility of version or compile-option mismatches with APR
             and APR-Util code. As a convenience, prepackaged source-code
             bundles of APR and APR-Util are occasionally also provided
             as a httpd-2.X.X-deps.tar.gz download.

生成Makefile文件并安裝

執(zhí)行configure文件,定義安裝位置為/app/httpd24,開啟動態(tài)鏈接功能,開啟ssl模塊。執(zhí)行命令./configure --prefix=/app/httpd24 --enable-so --with-ssl

執(zhí)行make命令,編譯二進(jìn)制文件,這是一個漫長的過程,等待完成即可。接著執(zhí)行make install安裝

更改系統(tǒng)配置

更改配置文件,永久關(guān)閉selinux
[root@centos7 /app/httpd24]#vim /etc/selinux/config

修改文件SELINUX=permission

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=permission
# SELINUXTYPE= can take one of three two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

systemctl stop firewalld 暫停防火墻
systemctl disable firewalld 取消防火墻開機(jī)自啟動

[root@centos7 /app/httpd24]#systemctl stop firewalld
[root@centos7 /app/httpd24]#systemctl disable firewalld
