mysql.so' for module DBD::mysql: libmysqlclient.so

在用perl连接数据库的时候出现错误，参考下：

写了一个备份程序，BackupMasterDB.pl    ，执行时报如下错误：
install_driver(mysql) failed: Can't load '/usr/lib64/perl5/site_perl/5.8.5/x86_64-linux-thread-multi/auto/DBD/mysql/mysql.so' for module DBD::mysql: libmysqlclient.so.15 无法打开共享对象文件: 没有那个文件或目录 at /usr/lib64/perl5/5.8.5/x86_64-linux-thread-multi/DynaLoader.pm line 230.
at (eval 3) line 3
Compilation failed in require at (eval 3) line 3.
Perhaps a required shared library or dll isn't installed where expected
at /home/admin/local/BackupMasterDB.pl line 51

上面错误一看是找不到libmysqlclient.so.15 ，先find吧

# find /usr/ -name "libmysqlclient.so*"                           
/usr/local/mysql/lib/mysql/libmysqlclient.so.15.0.0
/usr/local/mysql/lib/mysql/libmysqlclient.so.15
/usr/local/mysql/lib/mysql/libmysqlclient.so

解决方法：

echo "/usr/local/mysql/lib/mysql/" >>   /etc/ld.so.conf
ldconfig

完成
