安装源码包3步骤

1.   ./configure.这一步会自动检测Linux系统与相关的套件是否有编译该源码包时所需要的库，因为一旦缺少某个库，就不能完成编译。只有检测通过后，才会生成Makefile文件。

2.    make。使用这个命令，会根据Mkefile文件中预设的参数进行编译，这一步其实就是gcc在工作。

3.    make install。这一步是安装步骤，用于创建相关软件的存放目录和配置文件。

[root@lizhipeng01 yum.repos.d]# cd
[root@lizhipeng01 ~]# cd /usr/local/src/
[root@lizhipeng01 src]# ls

[root@lizhipeng01 src]# wget http://mirrors.cnnic.cn/apache/httpd/httpd-2.2.32.tar.gz

[root@lizhipeng01 src]# ls
httpd-2.2.34.tar.gz

[root@lizhipeng01 src]# tar -zxvf httpd-2.2.34.tar.gz   解压缩

[root@lizhipeng01 httpd-2.2.34]# ./configure --prefix=/usr/local/apache2

[root@lizhipeng01 httpd-2.2.34]# echo $?             上一条命令报错了，原因是没有gcc
