系統已安裝了gcc和cmake，如果沒有安裝請參考《CentOS-6.3安裝配置Cmake》。
執行以下操作：

代碼如下:
#檢查是否安裝了apache
[root@localhost /]# rpm -qa | grep httpd
httpd-2.2.15-15.el6.centos.1.x86_64
httpd-tools-2.2.15-15.el6.centos.1.x86_64
#卸載系統自帶的apache
[root@localhost /]# rpm -e --nodeps httpd-2.2.15-15.el6.centos.1.x86_64
[root@localhost /]# rpm -e --nodeps httpd-tools-2.2.15-15.el6.centos.1.x86_64
#使用yum卸載
[root@localhost apache]# yum remove apache

#檢驗apr版本，卸載安裝新版本
[root@localhost apache]# rpm -qa | grep apr
apr-1.3.9-5.el6_2.x86_64
apr-util-1.3.9-3.el6_0.1.x86_64
apr-util-ldap-1.3.9-3.el6_0.1.x86_64
#卸載apr
[root@localhost apache]# yum remove apr
yum remove apr-util-devel apr apr-util-mysql apr-docs apr-devel apr-util apr-util-docs
#安裝pcre
[root@localhost local]#  tar -zxv -f pcre-8.32.tar.gz
[root@localhost local]#  cd pcre-8.32
[root@localhost apr-1.4.6]# ./configure
[root@localhost apr-1.4.6]# make
[root@localhost apr-1.4.6]# make install

#安裝新版本apr
[root@localhost local]#  tar -zxv -f apr-1.4.6.tar.gz
[root@localhost local]#  cd apr-1.4.6
[root@localhost apr-1.4.6]# ./configure --prefix=/usr/local/apr
[root@localhost apr-1.4.6]# make
[root@localhost apr-1.4.6]# make install

#安裝apr-util
[root@localhost local]#  tar -zxv -f apr-util-1.5.1.tar.gz
[root@localhost local]# cd apr-util-1.5.1
[root@localhost apr-util-1.5.1]# ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@localhost apr-util-1.5.1]# make
[root@localhost apr-util-1.5.1]# make install

安裝apache
將httpd-2.4.3.tar.gz上傳到/usr/local中，執行以下操作：

代碼如下:
#執行安裝
[root@localhost local]# cd /usr/local
[root@localhost local]# tar -zxv -f httpd-2.4.3.tar.gz           #解壓壓縮包
[root@localhost local]# rm -rf httpd-2.4.3.tar.gz            #刪除壓縮包
[root@localhost local]# mv httpd-2.4.3 apache
[root@localhost local]# cd apache
#設置參數安裝
[root@localhost php5.4]# ./configure --prefix=/usr/local/apache --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util/
[root@localhost php5.4]# make
[root@localhost php5.4]# make install
