Lighttpd can't start, libssl.so.4&libcrypto.so.4 is missing.

LIGHTTD error Log in log/out_lighttpd, when the LIGHTTD can not start, the document will explain why.

Today's error is
Error while loading shared libraries:libssl.so.4

This is the failure to load the dynamic library, why failed, because the dynamic library is not found. There is no dynamic library called Libssl.so.4 in your environment.

The solution is to find a way to get one.

Method 1, copy one over the other machine.
For example, the machine 1 lighttd can get up, the Machine 2 does not come. Then the machine 1 must have this library, found, and then copied over to the good,
Find the method Find/-name "Libssl.so.4"
Copy over the general put in a few dynamic library place/lib,/lib64,/usr/lib,/usr/lib64. Here are a few of the default places to put the dynamic library, the program will go here to find.
Don't forget to chmod +x libssl.so.4 design executable permissions.

Method 2, if I can't copy it on another machine, or I don't see it, or not. That's right there.
Yum-y Install OpenSSL Openssl-devel
