部署Vue+Django 04c，mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

Ubuntu 22.04 LTS

 

root@VM-4-7-ubuntu:~# mysql
mysql: error while loading shared libraries: libncurses.so.5: cannot open shared object file: No such file or directory

 

使用find命令查找本机的libncurses文件

root@VM-4-7-ubuntu:~# find / -name 'libncurses*'
/usr/lib/x86_64-linux-gnu/libncursesw.so.6.4
/usr/lib/x86_64-linux-gnu/libncurses.so.6.4
/usr/lib/x86_64-linux-gnu/libncursesw.so.6
/usr/lib/x86_64-linux-gnu/libncurses.so.6
/usr/share/doc/libncurses6
/usr/share/doc/libncursesw6
/var/lib/dpkg/info/libncursesw6:amd64.shlibs
/var/lib/dpkg/info/libncurses6:amd64.shlibs
/var/lib/dpkg/info/libncurses6:amd64.triggers
/var/lib/dpkg/info/libncurses6:amd64.list
/var/lib/dpkg/info/libncursesw6:amd64.md5sums
/var/lib/dpkg/info/libncursesw6:amd64.list
/var/lib/dpkg/info/libncursesw6:amd64.triggers
/var/lib/dpkg/info/libncursesw6:amd64.symbols
/var/lib/dpkg/info/libncurses6:amd64.symbols
/var/lib/dpkg/info/libncurses6:amd64.md5sums

根据上面显示内容，没有对应的libncurses.so.5文件，这个时候可以将高版本创建软连接到5版本

ln -s /usr/lib/x86_64-linux-gnu/libncurses.so.6  /usr/lib/x86_64-linux-gnu/libncurses.so.5

 

root@VM-4-7-ubuntu:~# mysql
mysql: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

从描述中可以看出还缺少libtinfo.so.5文件

使用find命令查找本机的libtinfo文件
查找libtinfo

find / -name libtinfo.so*

/usr/lib/x86_64-linux-gnu/libtinfo.so.6.4
/usr/lib/x86_64-linux-gnu/libtinfo.so.6

同样的道理，将对应的高版本创建一个低版本的软连接

ln -s /usr/lib/x86_64-linux-gnu/libtinfo.so.6 /usr/lib/x86_64-linux-gnu/libtinfo.so.5
