源码安装Apache，报错：Cannot use an external APR with the bundled APR-util和httpd: Could not reliably determine the server's fully qualified domain name, using

一、解决APR和APR-util错误：

    1.1、安装APR：

[root@ganglia httpd-2.2.23]# cd srclib/apr
[root@ganglia apr]#  ./configure --prefix=/usr/local/apr   
root@ganglia apr]# make && make install

    1.2、安装APR-util：

[root@ganglia apr]# cd ../apr-util/
[root@ganglia apr-util]#  ./configure --prefix=/usr/local/apr-util --with-apr=/usr/local/apr
[root@ganglia apr-util]# make && make install

    1.3、安装apache，加入参数(--with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util)

[root@ganglia httpd-2.2.23]# ./configure --prefix=/usr/local/apache2 --enable-so --enable-mods-shared=most  --with-apr=/usr/local/apr --with-apr-util=/usr/local/apr-util
[root@ganglia httpd-2.2.23]# make && make install

二、解决httpd: Could not reliably determine the server's fully qualified domain name, using问题：
    2.1、进入apache的安装目录；

       Windows：D:Program FilesApache Software FoundationApache2.2conf

       Linux：/usr/local/apache/conf

    2.2、修改httpd.conf

     将里面的#ServerName localhost:80 注释去掉即可。

    2.3、再次重启http。
