以扩展的mysql.so的形式安装
2、找不到header file之类的
要yum install mysql-devel
find / -name mysql.h
/usr/include/mysql/mysql.h
查找到mysql.h文件，我们更改参数为--with-mysql=/usr，
如果没有的话，请安装mysql-devel包，
yum install mysql-devel
重新运行编译命令
3、要做软链接把mariadb的lib里的18（我是18）那个软连接过去
解决configure: error: Cannot find libmysqlclient under /usr.
今天在64位centos5.6系统上编译PHP5.2.17报错
checking for MySQL support... yes, shared checking for specified location of the MySQL UNIX socket... no checking for the location of libz... no checking for MySQL UNIX socket location... /var/lib/mysql/mysql.sock configure: error: Cannot find libmysqlclient under /usr. Note that the MySQL client library is not bundled anymore! [root@zjlca mysql]#
经查，问题是64位系统中 libmysqlclient 默认安装到了 /usr/lib64/mysql/ 目录下
而/usr/lib 目录下没有相应文件，但是php编译时，要去 /usr/lib目录下查找
解决方法：
ln -s /usr/lib64/mysql/libmysqlclient.so.18.0.0/usr/lib/libmysqlclient.so
