Error while loading shared libraries: 'libpcre.so.0: cannot open shared object file: No such file or directory'

Question

I just installed Passenger 3.0.11 and nginx and got this error:

Starting nginx: /opt/nginx/sbin/nginx: error while loading shared libraries: libpcre.s

Answer 1

I got the same error, and I fixed the problem by running sudo ldconfig.

Answer 2

just reinstall h5py conda, solved for me

Answer 3

I got the same error after I installed ClamAV, Antivirus for my Linux server.

Later I found below libraries got deleted from /lib64

libjson-c.so.2.0.1
libjson.so.0.1.0
libpcre.so.0 -> libpcre.so.0.0.1

I copied those from other server and uninstalled ClamAV.

Answer 4

There are few recommendations, with this I have solved the issue which I had.

• As mentioned above add the lib path in the /etc/ld.so.conf and check the same is updated or not by using ldconfig -v
• Add the LD_LIBRARY_PATH in the .bash_profile and refresh the same with . . bash profile.
• If the lib file is not get updated then use the updatedb to refresh the library list.

Answer 5

The message means what it says. The nginx executable was compiled to expect the PCRE (Perl-compatible Regular Expression) shared library to be available somewhere on LD_LIBRARY_PATH or specified in /etc/ld.so.conf or whatever equivalent library-locating mechanisms apply to your operating system, and it cannot find the library.

You will need to install PCRE - or configure your environment so that nginx will look for the PCRE library where it is installed.

Answer 6

Execute below command and restart server again.

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
