CentOS6上编译安装httpd2.4

sunren

在CentOS6上无法直接使用rpm包安装httpd2.4，因为httpd2.4依赖于：
  apr-1.4及以上版本

  apr-util-1.4及以上版本
而直接升级apr和apr-util会覆盖直接版本的程序，影响其他程序的依赖关系，所以一般使用编译安装的方式安装apr和apr-util，然后编译安装httpd2.4。


具体步骤如下：
1、准备安装环境和源码包
[root@localhost ~] # yum groupinstall "Development Tools" "Server Platform Development" -y
[root@localhost ~] # yum install pcre-devel -y下载源码包，这里我用到的是：
apr-1.5.0.tar.bz2
apr-util-1.5.3.tar.bz2
httpd.2.4.9.tar.bz2
2、编译安装apr和apr-util
[root@localhost ~] # tar xf apr-1.5.0.tar.bz2
[root@localhost ~] # cd apr-1.5.0
[root@localhost apr-1.5.0 ] # ./configure --prefix=/usr/local/apr   
//  为避免影响原有版本apr，将新版本apr安装到新的目录/usr/local/apr，--prefix选项为指定安装
目录
[root@localhost apr-1.5.0 ] # make && make install
[root@localhost ~] # tar xf apr-util-1.5.3.tar.bz2
[root@localhost ~] # cd apr-util-1.5.3
[root@localhost apr-util-1.5.3] # ./configure --prefix=/usr/local/apr-util --with-apr=/usr
/local/apr
//  同样将apr-util安装到新的目录，--with-apr指定apr所在目录
[root@localhost apr-util-1.5.3 ] # make && make install3、编译安装httpd2.4
[root@localhost ~] # tar xf httpd-2.4.9.tar.bz2
[root@localhost ~] # cd httpd-2.4.9
[root@localhost httpd-2.4.9 ] # ./configure --prefix=/usr/local/apache --sysconf=/etc/http
d24 --enable-so --enable-ssl --enable-cgi --enable-rewrite --with-zlib --with-pcre --with-
apr=/usr/local/apr --with-apr-util=/usr/local/apr-util --enable-modules=most --enable-mpms
-shared =all --with-mpm=prefork
// --prefix=/usr/local/apache ：安装位置
// -sysconf=/etc/httpd24 ：配置文件位置
// --enable-so ：支持DSO动态装载模块
// --enable-ssl ：支持SSL/TLS，可实现https协议访问，需要安装openssl-devel
// --enable-cgi ：支持CGI脚本
// --enable-rewrite ：支持URL重写
// --with-zlib ：使用指定的zlib压缩库，不指定路径会自动寻找
// --with-pcre ：使用指定的pcre库，增强的正则表达式分析工具；不指定路径会自动寻找，需要安装
pcre-devel
// --with-apr=/usr/local/apr ：指定依赖的apr程序安装位置
// --with-apr-util=/usr/local/apr-util ：指定依赖的apr-util程序安装位置
// --enable-modules=most ：支持动态启用模块：all：所有；most：常用
// --enable-mpms-shared=all ：编译并共享的模块
// --with-mpm=event ：默认启用的mpm模块；可选项有prefork|worker|event
[root@localhost httpd-2.4.9 ] # make && make install4、安装后配置
（1）添加环境变量，并重读文件
因为是编译安装的httpd，所以PATH环境变量里并没有我们所安装的目录，需要手动添加
[root@localhost ~] # vim /etc/profile.d/httpd24.sh
export PATH=/usr/local/apache/bin:$PATH
[root@localhost ~] # source /etc/profile.d/httpd24.sh添加完成后，执行httpd命令时，就可以正常使用，如果不添加到环境变量，则需要在绝对路径下使用，十分不便。
（2）导出头文件
[root@localhost ~] # ln -sv /usr/local/apache/include /usr/include/httpd不需要复制，创建软链接即可
（3）导出man手册
[root@localhost ~] # vim /etc/man.confg（4）编写服务脚本

[root@localhost ~]# vim /etc/rc.d/init.d/httpd
#!/bin/bash

exit $RETVA编写完服务脚本后，需要将服务脚本设为开机启动
