apache安装前常见错误:checking for pcre-config... false

apache常见错误总结:
1、./configure报错
Configuring Apache Portable Runtime library ...

checking for APR... configure: error: the --with-apr parameter is incorrect. It must specify an install prefix, a build directory, or an apr-config file.
解决办法:
下载安装
apr:http://apache.etoak.com//apr/apr-1.4.6.tar.gz
apr-utils:http://apache.etoak.com//apr/apr-util-1.4.1.tar.gz
或者yum -y install apr apr-util

 checking for pcre-config... false
configure: error: pcre-config for libpcre not found. PCRE is required and available from 
http://pcre.org/
解决办法:
[[email protected] httpd-2.4.1]# yum -y install pcre-devel
2、启动报错:
[[email protected] bin]# service apache start
AH00558: httpd: Could not reliably determine the server's fully qualified domain name, using localhost.localdomain. Set the 'ServerName' directive globally to suppress this message
httpd (pid 912) already running
其实在这里并不是报错,只是个提醒信息,解决办法比较多
(1)、在/etc/hosts写下当前ip与主机名的对应关系
(2)、在本机指能解析本机主机名的DNS

(3)、修改主配置文件,找到ServerName这一行写入本机主机名
