以下的情况一般出现在php和mysql不装在一台机器上的情况。
yum安装的mysql如果提示缺少libclient.so.20，则把libclientmysql.so.20放到/usr/lib64/下。
| 1 | ln -s /usr/lib/mysql /usr/lib64/mysql |
其目的就是让/usr/lib64/下存在libclient.so.20
| 1 | 注意：要保证/etc/ld.so.conf.d/mysql-x86_64.conf文件中存在/usr/lib64/mysql |
编译安装的mysql缺少libclient.so.20，则：
| 1 | cp /usr/local/mysql/lib/libmysqlclient.so.20 /usr/lib64/ |

默认的插件在/usr/local/php/lib/php/extension/no*
编辑php.ini把php插件统一放到extension目录：
| 12 | vi /usr/local/php/lib/php.iniextension_dir = "/usr/local/php/lib/php/extensions" |
安装pdo扩展：
#进入到php的安装包目录：cd php-5.6.30cd ext/pdo/usr/local/php/bin/phpize./configure --with-php-config=/usr/local/php/bin/php-config --enable-pdo=sharedmake && make installcp /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/pdo.so /usr/local/php/lib/php/extensions/ |
安装pdo_mysql扩展：
wget http://pecl.php.net/get/PDO_MYSQL-1.0.2.tgztar -zxvf PDO_MYSQL-1.0.2.tgzcd PDO_MYSQL-1.0.2/usr/local/php/bin/phpize #生成configure文件./configure -with-php-config=/usr/local/php/bin/php-config -with-pdo-mysql=/usr/local/mysqlln -s /usr/local/mysql/include/* /usr/local/include/make && make install 拷贝生成的文件：cp /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/pdo_mysql.so /usr/local/php/lib/php/extensions/编辑配置文件php.iniextension=pdo_mysql.so |
安装php-mysql扩展：
| 1 | cd php-5.6.30/ext/mysql |
/usr/local/php/bin/phpize ./configure --with-php-config=/usr/local/php/bin/php-config --with-mysql=/usr/local/mysqlmake && make install 拷贝生成的文件：cp /usr/local/php/lib/php/extensions/no-debug-non-zts-20131226/mysql.so /usr/local/php/lib/php/extensions/编辑配置文件：extension=mysql.so |
