So, it’s time to update my server! Currently, it’s hosted at DigitalOcean with an old Centos 6.5/2GB/40gb droplet. I pay a cool $20/month for my server for hosting, email, and about 10 other domains. It’s time to update!
So, I have to decide whether I will go with a Centos 7 or a Centos 8 image at $15/month. The only main difference is that I have to determine whether I need the updated Kernel and the additional updates and if my software/configs are easily portable to the new host.
I start my pre-migration experiment in 2 Virtual Machines using Oracle Virtuabox and the Centos7/Centos8 Minimal images. I get them installed, connected to the internet, yum update, and begin to install the necessary services that I’m currently running. I take a cool inventory of the versions I’m running, and the version that is currently available for install.
| – | Centos 6 | Centos 7 | Centos 8 |
|---|---|---|---|
| httpd | 2.2.15 | 2.4.6 | 2.4.37 |
| PHP | 7.2.26 | 5.4.16 | 7.2.11 |
| MySQL | 5.1.73 | (mariadb)5.5.65 | (mariadb)10.3.17 |
| dovecot | 2.0.9 | 2.2.36 | 2.2.36 |
| nginx | 1.10.3 | 1.16.1 | 1.14.1 |
| sendmail | 8.14.4 | 8.14.7 | 8.15.2 |
| postfix | 2.6.6 | 2.10.1 | 3.3.1 |
From the looks of what’s offered I quickly decide to go with Centos 8.
LET THE UPGRADE BEGIN!
