libmysqlclient.so.15: cannot open shared object file: No such file or directory

错误：

./mafsInRegion: error while loading shared libraries: libmysqlclient.so.15: cannot open shared object file: No such file or directory

解决方法：
1.下载 libmysqlclient.so.15 或是拷贝 libmysqlclient.so.15 到 /usr/lib (32位) 、/usr/lib64 (64位)

以64位centos为例：

下载地址 http://files.directadmin.com/services/es_5.0_64/libmysqlclient.so.15

#cd /usr/lib64
#wget http://files.directadmin.com/services/es_5.0_64/libmysqlclient.so.15

2.给libmysqlclient.so.15加x权限
#chmod 755 /usr/lib64/libmysqlclient.so.15

3.重新载入ldconfig
#ldconfig
