Mysql报错

mysql登录报错：mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

解决：mysql命令登录不成功，报错：mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory。按照百度的方法都不成功，应该和系统版本有关，后来自己想到一个方法：yum install libncurses*，完美解决问题。
