/usr/sbin/postconf: error while loading shared libraries: libmysqlclient.so.16

Last week I had an issue,  I am not able to log in Plesk Panel. The following error cracked my head:

Code: [Select]

ERROR: PleskUtilException

Up Level
Fatal error: plesk::Exc<&(plesk::ExecCmd::Failed(bool))>(Execution of /usr/sbin/postconf -d -h mail_version failed with return code 127.
Stderr is
/usr/sbin/postconf: error while loading shared libraries: libmysqlclient.so.16: cannot open shared object file: No such file or directory)
'/usr/lib64/libmysqlclient.so.16' exists, however 'ldd' command indicates that dynamic library is not found:

Code: [Select]

[root@ ~]# ldd /usr/sbin/postconf
        linux-vdso.so.1 =>  (0x00007fff6cdfe000)
        libsasl2.so.2 => /usr/lib64/libsasl2.so.2 (0x00007fdbb1e9d000)
        libpcre.so.0 => /lib64/libpcre.so.0 (0x00007fdbb1c71000)
        libmysqlclient.so.16 => not found
Yeah its because Dynamic library is being searched in the '/usr/lib64' or '/usr/lib' folders, but subfolders are ignored.

And here is the fix:

Create the symbolic link in the '/usr/lib64' folder and reconfigure the libraries links:

Code: [Select]

[root@ ~]# ln -s  /usr/lib64/mysql/libmysqlclient.so.16.0.0 /usr/lib64/libmysqlclient.so.16

[root@ ~]# ldconfig
