mysql: error while loading shared libraries: libtinfo.so.5

场景：服务器上删除mysql5.1.59版本后，安装新版本mysql 5.5 24，在初始化完成后，登录数据库时遇到如下问题：

mysql: error while loading shared libraries: libtinfo.so.5：cannot open shared object file: No such file or directory 

解决方法：

（1）先在/usr/lib64目录下查找文件，

lrwxrwxrwx. 1 root root 25 1月  11 2013 libtinfo.so -> ../../lib64/libtinfo.so.5

发现此文件不存在，

（2）直接从其他服务器上拷贝，（然后直接做软连接，此步可选择），并修改权限，即可！

scp libtinfo.so.5  root@192.168.0.X:/usr/lib64

chmod 777 libtinfo.so.5

具体方法参考如下：

ERROR:

mysql: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory 

1. checking for libmysqlclient installed.

[root@node01 mysqli]# ldconfig -v | grep mysql /usr/lib64/mysql:
libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0 libmysqlclient.so.16 -> libmysqlclient.so.16.0.0 [root@node01 mysqli]#
[root@node01 mysqli]# locate libmysqlclient.so /usr/lib64/mysql/libmysqlclient.so /usr/lib64/mysql/libmysqlclient.so.16 /usr/lib64/mysql/libmysqlclient.so.16.0.0 [root@node01 mysqli]# if output empty then simply run these commands on rpm\yum based linux:

yum install mysql-devel mysql-libs 
2. re-compile php-mysql module with path to lib64 folder.

./configure –with-php-config=/usr/local/php/bin/php-config –with-mysql=/usr/bin/ –with-libdir=lib64 
3. alternative solution is:

[root@node01 mysql]# ln -s /usr/lib64/mysql/libmysqlclient.so /usr/lib/mysql/libmysqlclient.so
