Re: MySQL v8.0: Unable to run MySQL binary

[Bjørn Munch]

First, 8.0.21 is nine releases and over two years old, I recommend using the newest version 8.0.30 if you're upgrading anyway.

You did not mention what MySQL package you installed, but I see mysql is linked with OpenSSL 1.1.1 and not with system OpenSSL 1.0.2. So this would be either the generic tarball or the el7 tarball.

Both packages includes a bundled OpenSSL 1.1.1 library but in order for mysql to find it, it needs to be installed in ../lib/private relative to the mysql binary. So if mysql is in /usr/bin, the bundled library needs to be in /usr/lib/private. This is also the case for the other libraries in lib/private in the MySQL tarball.

I assume you unpacked the 8.0.21 package somewhere and then moved the binaries to /usr/bin, but for 8.0 that is not enough. You also need those libraries. This is not needed for 5.7 since that links OpenSSL statically into the mysql binary.
