configure: error: Cannot find libmysqlclient under /usr. Note that the MySQL client library is not bundled anymore!
这个错误时因为在64位的linux系统中，libmysqlclient 默认安装到了 /usr/lib64/mysql/ 目录下，但是php编译时，要去/usr/lib目录下查找
解决办法：在/usr/lib目录下创建一个软连接
[root@localhost ~]# ls /usr/lib64/mysql/libmysqlclient*
/usr/lib64/mysql/libmysqlclient_r.so /usr/lib64/mysql/libmysqlclient_r.so.16.0.0 /usr/lib64/mysql/libmysqlclient.so.16
/usr/lib64/mysql/libmysqlclient_r.so.16 /usr/lib64/mysql/libmysqlclient.so /usr/lib64/mysql/libmysqlclient.so.16.0.0
[root@localhost ~]# ln -s /usr/lib64/mysql/libmysqlclient.so.16 /usr/lib/libmysqlclient.so
最后编译成功：
