今日重启php-fpm重启不了 ，报错信息如下：
[root@su ~]# /etc/init.d/php-fpm start
Starting php-fpm /usr/local/php/sbin/php-fpm: error while loading shared libraries: libmysqlclient.so.18: cannot open shared object file: No such file or directory
failed
解决方法：
[root@su~]# find / -name 'libmysqlclient.so.18'
/usr/local/webserver/mysql56/lib/libmysqlclient.so.18
进入到/usr/lib64目录下是否有该文件软链接
[root@su lib64]# ls libmysqlclient.so.18
ls: cannot access libmysqlclient.so.18: No such file or directory -不存在
重新软连接：
[root@su ~]# ln -s /usr/local/webserver/mysql56/lib/libmysqlclient.so.18 /usr/lib64/
[root@su ~]# /etc/init.d/php-fpm start
Starting php-fpm done
就OK了 。
