1.环境说明：

系统：CentOS 6.3 64位 Linux

PHP版本：5.3.13

Mysql版本：5.5.26

PHP安装目录：/usr/local/php

PHP配置文件：/usr/local/php/etc/php.ini

PHP扩展目录：/usr/local/php/lib/php/extensions/no-debug-non-zts-20090624/

MySQL安装目录：/usr/local/mysql

php.ini:

; Directory in which the loadable extensions (modules) reside.

extension_dir = "/usr/local/php/lib/php/extensions/no-debug-non-zts-20090624/"

2.编译安装扩展：

PHP扩展安装pdo_mysql模块，在Linux系统下进行，按以下步骤即可完成模块安装：

# tar -zxvf php-5.3.13.tgz

# cd php-5.3.13/ext/pdo_mysql

# /usr/local/php/bin/phpize

# cp /usr/local/mysql/bin/mysql_config /usr/bin/mysql_config

# ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysql-config=/usr/bin/mysql_config --with-pdo-mysql=/usr/local/mysql --enable-pdo=shared

# make && make install

备注：make test的时候会报错，但不影响编译安装的正常进行，可以忽略：

PHP扩展安装mysqli模块，在Linux系统下进行，按以下步骤即可完成模块安装：

# tar -zxvf php-5.3.13.tgz

# cd php-5.3.13/ext/mysqli

# /usr/local/php/bin/phpize

# ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysqli= /usr/bin/mysql_config

# make && make install

配置过程报错：

checking for mysql_set_server_option in -lmysqlclient... no

configure: error: wrong mysql library version or lib not found. Check config.log for more information.

configure: failed program was:

| /* confdefs.h. */

| #define PACKAGE_NAME ""

| #define PACKAGE_TARNAME ""

| #define PACKAGE_VERSION ""

| #define PACKAGE_STRING ""

| #define PACKAGE_BUGREPORT ""

| /* end confdefs.h. */

| /* Override any gcc2 internal prototype to avoid an error. */

| #ifdef __cplusplus

| extern "C"

| #endif

| /* We use char because int might match the return type of a gcc2

| builtin and then its argument prototype would still apply. */

| char mysql_set_server_option ();

| int

| main ()

| {

| mysql_set_server_option ();

| ;

| return 0;

| }

configure:3473: result: no

configure:3801: error: wrong mysql library version or lib not found. Check config.log for more information.

没有找到mysql库文件，说明mysql环境变量设置不正确或者mysql-devel库未安装。

yum -y install mysql-devel 或源码编译安装mysql-devel

3.修改PHP配置文件

sed -i '/pdo_mysql.so/d' /usr/local/php/etc/php.ini

sed -i '/^extension_dir/a extension = "pdo_mysql"' /usr/local/php/etc/php.ini

sed -i '/mysqli.so/d' /usr/local/php/etc/php.ini

sed -i '/^extension_dir/a extension = "mysqli"' /usr/local/php/etc/php.ini

4.重启apache或nginx，让配置生效：

/usr/local/apache/bin/apachectl -k restart 或 /etc/init.d/httpd restart

/usr/local/nginx/sbin/nginx -s reload 或 /etc/init.d/nginx restart

备注：

在编译 php 的时候加上了这个--with-mysqli=/usr/local/mysql/bin/mysql_config

所报错误是 configure: error: wrong mysql library version or lib not found

在编译的时候直接写--with-mysqli 不在添加路径，因为php本身有这个模块，不用再添加mysql 的配置文件路径。
