Ubuntu Static IP
Ubuntu Static IP KB ID 0001892 Problem Like most OSs out of the box the system is set to get it’s IP address from a DHCP server (i.e. dynamically). On the rare occasions I’m deploying Linux its to perform a specific task, so in nearly all cases I want it to have a static IP. Here is how to achieve that. Solution : Ubuntu Static IP Disable Cloud-Init Since Ubuntu version 18.04, it has shipped with this enabled, you can proceed with it...
KVM Bridge Network
Bridge Network KB ID 0001891 Problem Not sure why KVM does not come preconfigured for this out of the box, and it took me a very long time to work out how to do this. But if you want your KVM VMs to behave as if they are on your production LAN (rather than the default of setting up DHCP and NAT). The default is fine but if you want to access your VMs from outside the host you need to setup bridged networking. In my example I want my...
Install Ubuntu KVM
Ubuntu KVM KB ID 0001890 Problem I’ve been looking at KVM for a couple of reasons, firstly people are looking at VMware alternatives, now there’s no ‘free version’, and secondly the firm I work for have potentially a large KVM to VMware migration on the horizon, so I thought I’d build it on the test bench and see how best to address that migration scenario. Note: This was written with Ubuntu version 24.04,...
Certificate Chain Incomplete
KB ID 0001570 Problem The certificate here at PNL expired over the weekend, I got a new one and installed it. All appeared to be fine until I did an online check to make sure it was OK. The server’s certificate chain is incomplete Solution I had this problem once before, back then I was using Apache and CentOS7, and things were a little different, (now I’m using NGINX and Ubuntu 18.04). Essentially you see this error...
Linux – Install VMware Tools
KB ID 0001330 Problem Note: This is to install the VMware Tools NOT the OPEN-VM-TOOLS. I’ve had to do this a few times now, and every time I Goolge how to do it, I get pages of instructions on how to install the open vm tools. When what I really want is to install the VMware Tools. Solution I’m using vSphere ESX, but even if you are using VMware Workstation or VMware Fusion, you can still select ‘Install/Upgrade...
Nginx Error – 413 Request Entity Too Large
KB ID 0001325 Problem A few weeks ago I did a series on setting up a new WordPress site, shortly after I had some problems uploading my caching plugin (wp-rocket). This was the error I got; 413 Request Entity Too Large nginx/1.10.3 (Ubuntu) Anyway, I fixed the error, and a few days later I got an email from someone with the same problem, so I thought this time I would document the fix. Solution Note: I’m going to raise the...

Ubuntu: Allow SSH access for ‘root’ user
KB ID 0001317 Problem First of all not being able to connect to your Ubuntu server via SSH as root is ‘by design’, and it’s a perfectly good security measure. I do find it interesting that every hosting company I ever used, spin up a new machine and then email me the root password and they’ve enabled it anyway? I needed to enable this recently and the internet is full of posts saying ‘just edit the...
Ubuntu: Setting Up a WordPress Website with LEMP – Part 1
KB ID 0001318 Problem At the time of writing this site is running on CentOS7 LAMP (Linux Apache MySQL and PHP). Well I’m actually using MariaDB not MySQL as it’s ‘supposed’ to be a little faster, but they are similar enough to be accepted. I’m planning to migrate to Ubuntu 17 LEMP (Linux ‘EnginX’ MySQL and PHP) again with MariaDB. As the site is getting more traffic I want to utilise the...
