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

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.so.0: cannot open shared object file: No such file or directory

It's an old post, but hopefully might be useful for someone. I was trying to install/start up an older version of NGINX on Amazon-Linux 2 and encountered this error. NGINX is expecting libpcre.so.0, but the library wasn't available on Amazon-Linux 2.

Solution

  1. Searched for a later version of libpcre.so using find / -name libpcre.so*
  2. I found libpcre.so.1 symlinked to libpcre.so.1.2.0 in /usr/lib64/
  3. I created a new symlink to libpcre.so.1.2.0 and named it libpcre.so.0 using ln -s libpcre.so.1.2.0 libpcre.so.0
  4. Restarted NGINX and it worked

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

I copied those from other server and uninstalled ClamAV.

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.

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.
