perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
I was trying to install Oracle DB 21.0.0.0 on RHEL 8.4, but facing below error while executing runInstaller command due to which installation was aborted.
Error Description:
su - oracle
cd /u01/app/oracle/product/21.0.0/dbhome_1
[oracle@myblog dbhome_1]$ ./runInstaller
/u01/app/oracle/product/21.0.0/dbhome_1/perl/bin/perl: error while loading shared libraries: libnsl.so.1: cannot open shared object file: No such file or directory
[oracle@myblog dbhome_1]$
Solution:
Use below command check whether library "libnsl.so.1:" exists on server or not. This only works from your ORACLE_HOME location.
$su -
[root@myblog ~]# ldd /u01/app/oracle/product/21.0.0/dbhome_1/perl/bin/perl
linux-vdso.so.1 (0x00007ffd6addf000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f2e67321000)
libnsl.so.1 => not found
libdl.so.2 => /lib64/libdl.so.2 (0x00007f2e6711d000)
libm.so.6 => /lib64/libm.so.6 (0x00007f2e66d9b000)

libc.so.6 => /lib64/libc.so.6 (0x00007f2e665a9000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f2e66391000)
/lib64/ld-linux-x86-64.so.2 (0x00007f2e67541000)
Here, we can see that the library "libnsl.so.1:" is missing on server causing the issue. You can also verify the same by using below command. It shows whether respective packages are installed on server or not.
Install the RPM "libnsl-2.28-251.0.2.el8.x86_64.rpm"
[root@myblog ~]# rpm -ivh libnsl-2.28-251.0.2.el8.x86_64.rpm

Once you install the above RPM, you won't face this error again. You can start the installation now.
OR
You have an alternative option of creating Yum Repository and install missing RPM package.
[root@myblog ~]# dnf -q repoquery -f \*/libnsl.so.1
[root@myblog Oracle 21c]# cd /usr/lib64
[root@myblog lib64]# ls -ltr libnsl.so*
lrwxrwxrwx. 1 root root 15 Aug 12 2018 libnsl.so.2 -> libnsl.so.2.0.0
-rwxr-xr-x. 1 root root 116408 Aug 12 2018 libnsl.so.2.0.0
Solution is to install respective RPM packges through manual method or through Yum repository.
You can unzip the ISO image on your local desktop, copy the RPM package "
Here, i am using Yum repository method to install missing packges.
1) Mount the RHEL Setup CD and search the file "media.repo" file from mounted location.
Here, the mounted location is /media/sf_new/.
2) Copy the media.repo file from RHEL OS setup location "/media/sf_new/BaseOS/" to location "/etc/yum.repos.d/".
root@myblog sf_new]# cp media.repo /etc/yum.repos.d/rhel7dvd.repo
3) Make below changes in file "/etc/yum.repos.d/rhel7dvd.repo" i.e. set gpgcheck=1 and add below three parameters.
- gpgcheck=1
- enabled=1
- baseurl=file:///media/sf_new/BaseOS/
- gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
Old File:
[root@myblog sf_new]# cat /etc/yum.repos.d/rhel7dvd.repo
[InstallMedia]
name=Red Hat Enterprise Linux 8.4.0
mediaid=None
metadata_expire=-1
gpgcheck=0
cost=500
New File:
[root@myblog repodata]# cat /etc/yum.repos.d/rhel7dvd.repo
[InstallMedia]
name=Red Hat Enterprise Linux 8.4.0
mediaid=None
metadata_expire=-1
gpgcheck=1
cost=500
enabled=1
baseurl=file:///media/sf_new/BaseOS/
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
[root@myblog repodata]#
"/media/sf_new/BaseOS/" is a location where all RPMs are located from RHEL Image copy software.
[root@myblog sf_new]# chmod 644 /etc/yum.repos.d/rhel7dvd.repo
4) Install missing RPMs by using below command:
[root@myblog lib64]# yum install libnsl

5) Now verify missing library files exist or not. You can see the below output where the missing library file "libnsl.so.1:" exists post installing RPMs.
