执行命令：mysql -u root -p
错误：error while loading shared libraries: libncurses.so.5: cannot open shared object file
分析：缺少 libncurses.so.5
解决方案:
yum install libncurses.so.5
另外一个方案参考博客:解决CentOS缺少共享库：libstdc++.so.6
当在CentOS 6.2下执行某些命令时，有缺少共享库的报错：
error while loading shared libraries: libstdc++.so.6: cannot open shared object file: No such file or directory
解决办法：
1、执行命令： yum whatprovides libstdc++.so.6
然后会提示哪个安装包有这个库文件如下：
[root@localhost ~]# yum whatprovides libstdc++.so.6
Loaded plugins: aliases, changelog, downloadonly, fastestmirror, kabi, presto, refresh-packagekit, security, tmprepo, verify,

libstdc++-4.4.7-3.el6.i686 : GNU Standard C++ Library
Repo : base
Matched from:
Other : libstdc++.so.6
2、然后执行：
yum install libstdc++-4.4.7-3.el6.i686
搞定！
