场景1： httpd server不能够编译，

错误如下：

configure: error: in `/opt/httpd-2.2.19/srclib/apr':
configure: error: no acceptable C compiler found in $PATH
See `config.log' for more details.
configure failed for srclib/apr

原因:缺少c编辑器，比如 GCC或GCC+等。

解决方案：下载GCC编译器并编译它。

场景2 Apache不能够使用make命令编译，显示已存在该进程。

Error: make is not able to compile the code

原因：make不能够执行该函数

解决方案： 运行下面命令

make clean
#Then
make
make install

场景3 Apache HTTP服务器不能够连接到TOMCAT7

Error:不能通过 AJP连接

原因：端口被阻止或者AJP的配置有错误

解决方案：使用下列命令检查日志
