1 最好先安装组件

[root@localhost ~]# yum groupinstall additional development
[root@localhost ~]# yum groupinstall development tool

2 安装ap1.5.2r(Apache Portable Runtime),安装apr-util 1.5.4工具

[root@localhost ~]wget http://mirrors.cnnic.cn/apache//apr/apr-1.5.2.tar.gz
[root@localhost ~]# tar xzvf  apr-1.5.2.tar.gz
[root@localhost apr-1.5.2]# ./configure --prefix=/usr/local/apr/

如果报错：rm: cannot remove `libtoolT': No such file or directory，请编辑configure这个文件，将 $RM "$cfgfile" 那行注释掉

[root@localhost apr-1.5.2]#make&&make install

安装apr-util工具

[root@ns2 ~]wget http://mirrors.cnnic.cn/apache//apr/apr-util-1.5.4.tar.gz

编译选项注意有 --apr选项

[root@localhost ~]# tar xf apr-util-1.5.4.tar.gz
[root@localhost ~]# cd 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&&make install

3 centos默认安装了pcre，所以不需要安装pcre，否则请安装pcre-devel哦

4 安装httpd 2.4.12（2015-6-6新）

[root@localhost ~]# tar xf httpd-2.4.12.tar.bz2
[root@localhost ~]# cd httpd-2.4.12

打算编译选项加上（注意不明确的请查看./configure -h不要瞎写，写完和自己的对照一下，是否有问题）

基本选项，包括安装路径，配置文件路径

--prefix=/usr/local/apache指定安装的大路径

--sysconfdir=/etc/httpd指定配置文件的路径

模块允许选项，允许模块使用，大部分动态允许mpm等

--enable-so允许模块化使用

--enable-modules=most添加大多数的模块

--enable-mods-shared=most

--enable-mpms-shared=all支持所有的mpm模型

--enable-cgi --enable-cgid支持cgi程序

--enable-ssl支持ssl从而支持https

--enable-rewrite支持url重定向

指定和apr，apr-util的联系与绑定

--with-include-apr

--with-apr=/usr/local/apr指定apr

--with-apr-util=/usr/local/apr-util指定apr-util

[root@localhost httpd-2.4.12]# ./configure --prefix=/usr/local/apache  --sysconfdir=/etc/httpd --enable-so --enable-modules=most --enable-mods-shared=most --enable-mpms-shared=all --enable-cgi --enable-cgid --enable-ssl --enable-rewrite --with-include-apr --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
[root@localhost httpd-2.4.12]#make&&make install

如果报错

configure: WARNING: OpenSSL version is too old

no

checking whether to enable mod_ssl... configure: error: mod_ssl has been requested but can not be built due to prerequisite failures

安装openssl-devel即可

编译安装完

进入安装后的目录

[root@localhost bin]# cd /usr/local/apache
[root@localhost apache]# ls
bin  build  cgi-bin  error  htdocs  icons  include  logs  man  manual  modules
[root@localhost apache]# cd bin/
[root@localhost bin]# ./apachectl

然后打开网页试试，输入你的虚拟机ip即可

如果不能打开，考虑如下

[root@localhost bin]# service iptables stop
[root@localhost bin]# getenforce
Enforcing
[root@localhost bin]# setenforce 0
[root@localhost bin]# vim /etc/selinux/config

改为permissive

修改文件夹属性

[root@localhost bin]#chmod 755 /usr/local/apache/

再刷新试试

上述的好了，网页出现it works！后

我们可以把命令复制到/etc/init.d/httpd实现service调用，总之，一切为了实现之前使用httpd rpm包的那个习惯，嘿嘿

[root@localhost bin]# cp /root/httpd-2.4.12/build/rpm/httpd.init /etc/init.d/httpd
[root@localhost bin]# chmod +x /etc/init.d/httpd

修改文件

建议三处

1. httpd=${HTTPD-/usr/local/apache/bin/httpd}

2. pidfile=${PIDFILE-/var/run/httpd/${prog}.pid}

3. CONFFILE=/etc/httpd/httpd.conf

别急着启用服务

创建相应的目录

[root@localhost bin]# mkdir /var/run/httpd/

为了使用httpd -t等命令，修改~/.bash_profile

修改为PATH=$PATH:$HOME/bin:/usr/local/apache/bin

[root@localhost bin]# vim ~/.bash_profile
[root@localhost bin]# source  ~/.bash_profile
[root@localhost bin]# httpd -t
Syntax OK

在/etc/httpd/httpd.conf加上这行

PidFile "/var/run/httpd/httpd.pid"

为log文件创建符合链接

[root@localhost bin]# ln -s /usr/local/apache/logs/* /var/log/httpd/

然后重启服务看是否ok

如果不行请查看日志文件等

[root@localhost bin]# service httpd restart
Stopping httpd:                                            [ OK ]
Starting httpd:                                            [ OK ]

如果不能重启，比如这个错误

Stopping httpd:                                            [FAILED]

Starting httpd: (98)Address already in use: AH00072: make_sock: could not bind to address [::]:80

(98)Address already in use: AH00072: make_sock: could not bind to address 0.0.0.0:80

no listening sockets available, shutting down

AH00015: Unable to open logs

[FAILED]

[root@testA bin]# service httpd stop

Stopping httpd:                                            [FAILED]

这时候去找httpd.pid文件即可

把/usr/local/apache/logs/httpd.pid 移到/var/run/httpd/下即可

然后再次查看网页是否正常，最终搭建最新httpd2.4.12的任务已经完成！
