Ubuntu 16.04 LTS was around for few months now. Today I got some free to check it out. It’s so much better than Ubuntu 14.04 I had been using. So I decided to upgrade my server to Ubuntu 16.04 LTS and thought it might be helpful to post a tutorial so my readers can upgrade their servers too.
Ubuntu 16.04 now ships with Nginx v1.10, PHP v7 and MySQL v5.7. You had only got Nginx v1.4.6, PHP v5.6 and MySQL v5.7 with my old Virtualmin-Nginx setup on Ubuntu 14.04 LTS. That right there is a good reason to upgrade. I’ve tested this setup on my server and its working. It’s working great. You’ll clearly see performance improvements of your website.
And I’m sure you all heard about PHP 7 and how it’s so much better and faster than previous versions of PHP. Now you can enjoy its benefits on your server. And MySQL is gone. It had been replaced by MariaDB. But unfortunately Virtualmin still uses MySQL. You can replace MySQL with MariaDB but i’m not going to deal with it on this post. There are so many good things to say, But I think we should get to the installation.
I’m going to assume that you already have a VPS with root access. If you don’t, you can get one from a unmanaged VPS providers I recommend. Logged in to Ubuntu 16.04 server as root user, run following command to output your server’s hostname.
If the output is anything other than your domain name or a sub-domain, you should change it before you install VIrtualmin. Refer to change Ubuntu 16.04 hostname from command line tutorial and change it now.
This part is similar on all Linux distributions. Download the Virtualmin installation script to your server,
Run the script to install Virtualmin.
sh /root/install.sh -b LEMP
You’ll be asked to confirm the action. Confirm it and Virtualmin installation will begin. It’ll take few minutes for the installer to complete. It’ll setup Nginx 1.10, PHP 7 and MySQL 5.7. You’ll be asked for permission to a swap file if your server has less than 1GB of RAM. You’ll be greeted with following message on your Putty screen when Installation completed.
Installing PHP 7 Modules
You’ll need few PHP modules installed on your server for some php applications to work. Following command will install essential PHP 7 modules on your server.
apt-get install memcached php7.0-mysql php7.0-curl php7.0-gd php-pear php-imagick php7.0-imap php7.0-mcrypt php-memcache php7.0-tidy php7.0-xmlrpc php7.0-xsl php7.0-mbstring php7.0-zip
Running Virtualmin Post-Installation Wizard
You can access Virtualmin on following URL with your root password. Make sure you replace example.com with your domain name. Your DNS should be propagated for this to work. If DNS isn’t propagated yet, you can replace eaxmple.com with your server’s IP address.
You’ll be taken to the Virtualmin Post-Installation Wizard after the login. It is pretty self-explanatory, just remember to select MySQL as database server and Only store hashed passwords as password storing method. You’ll be good with default selections for all other steps.
You’ll be given an option to check Virtualmin configurations after the Post-Installation wizard. Click Recheck and refresh configuration button to check your server for errors. The most common error I’ve encountered was system is not setup to use itself as a DNS server. If everything goes well, you’ll be greeted with .. your system is ready for use by Virtualmin.
Securing MySQL Databases
There is more you can do to secure MySQL databases. But at this point, running following command will guide you through changing some dangerous default settings. My input for the first question was No and Yes to everything else. It’ll also ask you for a new MySQL password. You don’t need to change it here just type the same password you set on Virtualmin post-installation wizard.
That concludes Virtualmin-Nginx installation on Ubuntu 16.04. Your VPS is now fully configured to host websites using Nginx as the web server.
