Hello again, I am now starting up on upgrading my services through Nginx (have worked with Apache for a few years now). I have stood up a new server and followed this tutorial: https://www.howtoforge.com/tutorial/perfect-server-ubuntu-18-04-nginx-bind-dovecot-and-ispconfig-3/ Even though it appears that all is working, but I want your help to be sure before doing a lot more work on this new server. I have the following concerns/questions: 1. On section 6. (Mysql), the instruction is: However, what I got was this: I did comment the "[client-server]" line, as I interpreted this to be the same as the step in the tutorial. Is this OK? or should I worry or do something different? 2. On step 16, (Installing ISP Config, at the step where the RSA key is created to secure it, instead of showing (as in the tutorial) "Generating a 4096 bit RSA private key" In my server, the output was only "Generating a RSA private key". Is this an error? Or an omission on my end to set it up? Would there it be any negative impact to the set up? 3. I was intending to upgrade the server to Ubuntu 20 after setting ISP Config up, but I would like your insight on that. Would you please advise me whether I should upgrade the OS or just keep it as-is? 4. On the same token, I noticed that Nginx installed as version 1.14 while there is a latest build (1.18/1.19) available. Is there a way to correctly upgrade versions? 5. And lastly, when I finished installing ISP Config 3.2.2. I remembered that there are dependencies to be installed, and then I went and did install them. Is that wrong? Should I re-do the set up installing the dependencies first? At the point I'm at I can comfortably trash everything and re-do it all if needed, I appreciate your help!
