报错处理：libmysqlclient.so.20: cannot open shared object file: No such file or directory

此次错误出现在R安装RMySQL时报错。

libmysqlclient.so.20: cannot open shared object file: No such file or directory

原因是libmysqlclient.so.20文件找不到，一般会出现在二进制包安装MySQL。
解决方法：

[root@TestServer ~]# find / -name libmysqlclient.so.20
/usr/local/mysql/lib/libmysqlclient.so.20
[root@TestServer ~]# ln -s /usr/local/mysql/lib/libmysqlclient.so.20 /usr/lib64/libmysqlclient.so.20

重新安装RMySQL就不会再报错了。
