/runInstaller Oracle 19c-无法验证图形显示设置

Question

在CentOS 8上安装Oracle 19c时出现问题。

[hadoop@localhost dbhome_1]$ sudo ./runInstaller
[sudo] password for hadoop: 
ERROR: Unable to verify the graphical display setup. This application requires X display. Make sure that xdpyinfo exist under PATH variable.
/u01/app/oracle/product/19.0.0/dbhome_1/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
[hadoop@localhost dbhome_1]$ 

• X跑步

[hadoop@localhost dbhome_1]$ ps -e | grep X 
2171 tty1     00:00:00 Xwayland
2578 tty2     00:00:22 Xwayland

• 是否会因为使用localhost.domain而发生此错误

环境变量：

# Java 
export JAVA_HOME=/opt/jdk
export PATH=$PATH:$JAVA_HOME/bin
# Oracle
export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=localhost.localdomain
export ORACLE_UNQNAME=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/19.0.0/dbhome_1
export ORA_INVENTORY=/u01/app/oraInventory
export ORACLE_SID=orcl
export DATA_DIR=/u02/oradata
export PATH=/usr/sbin:/usr/local/bin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib

• /etc/hosts根据ifconfig进行文件配置：

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.15.3 localhost.localdomain

• IP地址192.168.15.3是从ifconfig中提取的：

[hadoop@localhost dbhome_1]$ ifconfig
wlo1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
inet 192.168.15.3  netmask 255.255.255.0  broadcast 192.168.15.255

• Java版本：

[hadoop@localhost dbhome_1]$ java -version
java version "1.8.0_281"
Java(TM) SE Runtime Environment (build 1.8.0_281-b09)
Java HotSpot(TM) 64-Bit Server VM (build 25.281-b09, mixed mode)

Answer 1

解决图形显示错误的方法是将设备名称从"更改为"；localhost"；至"；数据服务器"；并使用另一个用户名"；甲骨文；组名称为"；oinstall"；。

此外，我将dbhome_1的所有权从"；根"；至"；甲骨文：oinstall"用户名和组名。

使用sudo dnf install libnsl可以很容易地安装libnsl.so.1库。
