（1）尝试通过Yum安装，提示已安装
[root@localhost yum.repos.d]# yum install -y libncurses*

[root@localhost yum.repos.d]# 


（2）查找libncurses开头的文件
[root@localhost yum.repos.d]# find / -name 'libncurses*'
/usr/lib64/libncurses++.so
/usr/lib64/libncurses++w.so
/usr/lib64/libncurses++w.so.6.3
/usr/lib64/libncursesw.so.6
/usr/lib64/libncurses++.so.6.3
/usr/lib64/libncurses.so.6.3
/usr/lib64/libncurses++.so.6
/usr/lib64/libncursesw.so.6.3
/usr/lib64/libncurses++w.so.6
/usr/lib64/libncurses.so
/usr/lib64/libncurses.so.6
/usr/lib64/libncursesw.so
[root@localhost yum.repos.d]# cd /usr/lib64/


（3）查看链接文件，实际文件为libncurses.so.6.3
[root@localhost lib64]# ls -l libncurses.so.*
lrwxrwxrwx. 1 root root     17 12月 27 18:04 libncurses.so.6 -> libncurses.so.6.3
-rwxr-xr-x. 1 root root 174128 12月 27 18:04 libncurses.so.6.3


（4）配置软链接
[root@localhost lib64]# ln -sf libncurses.so.6.3 /usr/lib64/libncurses.so.5
[root@localhost lib64]# ls -l libncurses.so.*
lrwxrwxrwx. 1 root root     17  4月 18 18:54 libncurses.so.5 -> libncurses.so.6.3
lrwxrwxrwx. 1 root root     17 12月 27 18:04 libncurses.so.6 -> libncurses.so.6.3
-rwxr-xr-x. 1 root root 174128 12月 27 18:04 libncurses.so.6.3
[root@localhost lib64]# 

（5）测试正常访问
[root@localhost lib64]# /opt/mysql/mysql_base/bin/mysql -uroot -p
