mysql 登录报错

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,
              : versionlock
 Loading support for CentOS kernel ABI
 Loading mirror speeds from cached hostfile
  * base: centos.ustc.edu.cn
  * centosplus: centos.ustc.edu.cn
  * contrib: centos.ustc.edu.cn
  * extras: centos.ustc.edu.cn
  * updates: centos.ustc.edu.cn
 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
