安装LAMP环境，服务器是CentOS（VM虚拟机上搭建的），自带有MYSQL。
也可以所以用yum命令直接安装mysql
yum install mysql
yum install mysql-server
yum install mysql-devel
然后查看所在位置：
[[email protected] php-5.5.13]# whereis mysql
mysql: /usr/bin/mysql /usr/lib64/mysql /usr/include/mysql /usr/share/mysql /usr/share/man/man1/mysql.1.gz
[[email protected] php-5.5.13]# which mysql
/usr/bin/mysql
[[email protected] php-5.5.13]# pwd
/home/default7/Downloads/php-5.5.13
[[email protected] php-5.5.13]#
[[email protected] php-5.5.13]# find / -name my.cnf
/etc/my.cnf
[[email protected] php-5.5.13]# pwd
/home/default7/Downloads/php-5.5.13
[[email protected] php-5.5.13]# ./configure --prefix=/usr/local/php5 --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql=/usr/share/mysql
运行最末尾报错（最末尾几段）：

Apache\PHP都已经安装好，就是MYsql不知到哪里去来 --with-mysql=这个路径我把 whereis mysql里面的每一个都试了都mysql错。mysql到底装到哪里去了。
configure: error: Cannot find MySQL header files under /usr/share/mysql.

/usr/share/mysql 文件夹内容

[[email protected] mysql]# cd bin

[[email protected] mysql]#
------解决方案--------------------
用whereis之类的命令找
------解决方案--------------------
[[email protected] php-5.5.13]# which mysql
/usr/bin/mysql
不是告诉你mysql在/usr/bin/mysql吗？为什么还要用/usr/share/mysql？
------解决方案--------------------
Cannot find MySQL header files
这是由于安装mysql时没有安装mysql头文件，或者是路径指定不正确,php找不到mysql的头文件引起的错误提示。
执行下
find / -name "mysql"
