runInstaller安装时报错，提示缺少库文件

刘泽宇

部署oracle19c，执行./runInstaller，无论调用图形界面还是试用静默安装，都是报错，提示：
/soft/oracle/app/oracle/product/19.3.0/db_1/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory。
该问题实际原因是缺失库文件导致

报错信息：
[oracle@DATABASE db_1]$ ./runInstaller

ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
/soft/oracle/app/oracle/product/19.3.0/db_1/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory

解决方案
安装库包libnsl，命令为yum install libnsl

安装该库包后重新执行 ./runInstaller ，原来的报错“/soft/oracle/app/oracle/product/19.3.0/db_1/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory”消失。
