           ln -s /usr/local/mysql/include/- /usr/local/mysql/include/mysql/
           make ZEND_EXTRA_LIBS = '-liconv' 


在安装nginx + mysql + php 的时候出现这样的错误：
/usr/local/src/php-5.2.15/ext/mysqli/mysqli.c:644: error: (Each undeclared identifier is reported only once
/usr/local/src/php-5.2.15/ext/mysqli/mysqli.c:644: error: for each function it appears in.)

make: *** [ext/mysqli/mysqli.lo] Error 1

这样真正的解决方法是：
修改/usr/local/include/mysql/mysql.h 文件内容：
（mysql.h这个是根据个人安装的mysql路径来找  在mysql下面的include的mysql目录里  别搞错了）
找到
enum mysql_protocol_type 
{ 
MYSQL_PROTOCOL_DEFAULT, MYSQL_PROTOCOL_TCP, MYSQL_PROTOCOL_SOCKET, 
MYSQL_PROTOCOL_PIPE, MYSQL_PROTOCOL_MEMORY 
}; 
在这个中间添加这些内容
++++++++++++++++++++++++++++++++++++++++++++
/* 
There are three types of queries - the ones that have to go to 
the master, the ones that go to a slave, and the adminstrative 
type which must happen on the pivot connectioin 
*/ 
enum mysql_rpl_type 
{ 
MYSQL_RPL_MASTER, MYSQL_RPL_SLAVE, MYSQL_RPL_ADMIN 
};
++++++++++++++++++++++++++++++++++++++++++++
typedef struct character_set 
{ 
unsigned int number; /* character set number */ 
unsigned int state; /* character set state */ 
const char *csname; /* collation name */ 
const char *name; /* character set name */

아파치가 버전업하면서 해당 심볼의 명칭을 바꾼것으로 unixd_config 를 ap_unixd_config로 수정하면된다.

파일 위치는 php-5.2.xxx/sapi/apache2hander/php_functions.c

이렇게 바꾸고 compile하고 실행하면 문제없이 실행된다.
