1，下載apache(httpd)源碼；
2，檢查當前系統中是否已安裝過apache，如安裝過，則需要先卸載；
3，需要依賴APR，所以要先安裝APR庫支持和PCRE；
APR下載：http://apr.apache.org/download.cgi
PCRE下載：http://www.pcre.org/
注：編譯pcre時報錯要求安裝c++編譯器：
configure: error: You need a C++ compiler for C++ support.
安裝編譯器即可：
[root@localhost pcre-8.38]# yum install gcc-c++
[root@localhost pcre-8.38]# yum install gcc
------------以下安裝APR+PCRE----------------
[root@localhost apr-1.4.5]# pwd
/usr/local/apr-1.4.5
[root@localhost apr-1.4.5]# ./configure --prefix=/usr/local/apr
[root@localhost apr-1.4.5]#make
[root@localhost apr-1.4.5]#make install
[root@localhost apr-util-1.5.4]# pwd
/usr/local/apr-util-1.5.4
[root@localhost apr-util-1.5.4]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr/
[root@localhost apr-util-1.5.4]#make
[root@localhost apr-util-1.5.4]#make install
[root@localhost pcre-8.38]# pwd
/usr/local/pcre-8.38
[root@localhost pcre-8.38]#./configure --prefix=/usr/local/pcre
[root@localhost pcre-8.38]# make
[root@localhost pcre-8.38]# make install
4，解壓apache，進行安裝即可。
1）進入當前apache目錄：#./configure --prefix=/usr/local/apache --with-apr-util=/usr/local/apr-util/ --with-pcre=/usr/local/pcre/
2）make
3) make install
5，完成安裝後進行相關配置。
啓動httpd服務（實際路徑：/usr/local/apache/bin/apachect1，拷貝到/etc/init.d服務目錄下）
提示servername未設置：
[root@localhost apache]# /etc/init.d
/httpd restart
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
[root@localhost apache]#
解決：
[root@localhost apache]#vi /usr/local/apache/conf/httpd.conf
添加主機名即可：
………………
ServerRoot "/usr/local/apache/"
#+++++++++++++++++++++++++
ServerName localhost:80
#+++++++++++++++++++++++++
………………
重啓服務不會再提示servername的問題。
測試httpd://x.x.x.x顯示It works!即說明安裝正常。
