I am new to this unmanaged vps host so wanting to setup a linode server. I want to install secured ubuntu os with lamp stack also vesta control panel for my wordpress site. So I need help to setup all these things. Also I need some tweaks to make my website super fast & secure. I want low maintenance on servers after setup gets finished as I don't have enough knowledge if any trouble occurs in future. Please provide me a full guide on this.
Uhm... you clearly shouldn't be doing this - as you say yourself, you don't have any knowledge if you get into trouble. And believe me, you will. Besides, there are hundreds of tutorials out there - just Google? Or have a look at the support / forums at Linode.
I am going to have to agree here. You are going to at least want some sorta UI. It would take me longer to write you the guide than it would to build it real fast but even as a part time server guy I have no interest in having to command line stuff like a wp install. That is just silly these days. I would have probably suggested centos as well. N.
If this site is a production level site, I have to agree with what the previous posters said. If you " don't have enough knowledge if any trouble occurs in future," you probably shouldn't be running an unmanaged vps, as there is always a possibility of a problem arising, no matter how good your setup is. Instead, you might want to look into a shared hosting provider. Most of them even have a one-click WordPress install feature. However, if you really want to learn how to manage a vps, I would suggest starting in the tutorial section of either Linode's or DigitalOcean's website. I find that their articles are very informative and very well written. Here's a couple articles to get you started: https://www.linode.com/docs/getting-started https://www.linode.com/docs/security/securing-your-server https://www.linode.com/docs/websites/lamp/lamp-on-ubuntu-14-04 https://www.linode.com/docs/websites/cms/how-to-install-and-configure-wordpress
