I encountered the following error in Nginx.
$./nginx ./nginx: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directory $
If you are getting above error while starting Nginx, you can fix by following.
This happens due to following three reasons.
- You don’t have PCRE installed
- Nginx was not compiled & installed using
- PCRE library is not set in
There are multiple ways to troubleshoot and fix this issue.
Let’s understand the error and fix it accordingly.
nginx: error while loading shared libraries: libpcre.so.1
Nginx is looking for a file
libpcre.so.1 which comes under PCRE library and usually installed on UNIX.
libpcre.so.1 using find command
$find / -name libpcre.so.1 /usr/local/lib/libpcre.so.1 $
Ok, so I do have this file which means PCRE is already installed and will proceed with next troubleshooting step.
Note: If you don’t get find results then you got to install PCRE with the below command.
yum install pcre
If you don’t have root privilege, then you may ask the system administrator to install it.
Now, let’s set LD_LIBRARY_PATH as we could see libpcre.so.1 is available under /usr/local/lib
Start Nginx, it should be right now.
