今天从db01上copy复制一个mysql库到db02上,前面操作已经顺利。数据库也可以正常启动。本以为ok了,结果在执行命令登录mysql库时,报如下错误:

- [root@db02 ~]# mysql3306
- /data/mysql-3306/bin/mysql: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory
解决方法:
1.从db01好用的一台mysql服务器上,将两个lib包拷贝到db02相应路径:

- [root@fz-db01 ~]# scp -r /lib/libtinfo.so.5.7 192.168.1.2:/lib/
- libtinfo.so.5.7 100% 96KB 95.8KB/s 00:00
- [root@fz-db01 ~]# scp -r /lib64/libtinfo.so.5.7 192.168.1.2:/lib64/
- libtinfo.so.5.7 100% 135KB 135.0KB/s 00:00
2.在db02上创建相应的软链接:

- [root@db02 ~]# ln -sn /lib/libtinfo.so.5.7 /lib/libtinfo.so.5
- [root@db02 ~]# ln -sn /lib64/libtinfo.so.5.7 /lib64/libtinfo.so.5
3.再次执行连接命令进行测试如下:

- [root@db02 ~]# mysql3306

本来是一个很简单的问题,从网上下载lib包啥的,查资料愣是折腾了好半天;其实,回头认真思考一下,就很容易想到可以从好用的那台mysql库入手,将问题解决掉的。简单记录下来,留做备忘吧!
