MySQL master-slave replication is well covered so I won’t go deep into explanations and details. This supposes to be a simple how-to tutorial. However, I’m going to pinpoint a few details that might lead you astray while doing this easy setup.
When you enter the field of multiple MySQL instances on one physical server you might run into the trouble. Lack of documentation, cryptic bugs, and insane settings is something you need to get used to. I almost quit a few times in the process and only my habit of trying unusual things when everything logical failed kept me up to the solution.
There are many reasons for BIND server not to work. BIND is quite old and stable open source project so if it doesn’t work it’s usually something related to configuration and less likely something due to the compilation, installation or bug in the package. Also, there are more than few uses of BIND server so configurations can vary from one use case to another.
There are some situations when you need to check size of directories on your Linux server. Usually it’s due to logging which can consume your hard disk, especially if you have heavy traffic web site or if you log some common type events. Log rotation can help but you need to configure it properly according to your hard disk size.
It’s not always easy or possible to setup port forwarding so you can access your home PC or any other device through public IP your internet service assigns you. Problem is also if your ISP rotate IPs so you always need to keep track of it. One option is to try to convince ISP to give you static IP but traffic routing on ISP side can be also behind NAT, which might be complicated to configure and guys from ISP tend to tell you forwarding is not possible.
So what can you do about that? Sometimes nothing. 🙂
So you’re trying to install Hitch for SSL termination on your Ubuntu 16.04 server? Or you might think it’s good idea because you have it working on some other Linux distribution like CentOS?

This is where you can return to Google to look for other site if you’are looking for how to tutorial on Hitch with Ubuntu. However you might continue reading to see what kind of mess you might encounter.
