I phased out and removed the CentOS 7.5 WordPress servers.  The backup performance was over 2x as slow as Ubuntu 16.04 using VEEAM.   I will keep this page for my CentOS notes for other users out there. 

I upgraded from 5.5.56 to 10.3.8 by creating /etc/yum.repos.d/MariaDB.repo

# MariaDB 10.3 CentOS repository list – created 2018-07-16 19:32 UTC
# http://downloads.mariadb.org/mariadb/repositories/
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.3/centos7-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY -MariaDB
gpgcheck=1

Check out my MariaDB pages.   When going to 10.3, you really need to go to 10.1 and I give a trick to get mysql-upgrade working.   

Re: BIOS choice.  I was on 4.18.11 because of a report of a serious bug in 4.18.10 and earlier.   The other day I upgraded to 4.19 becausee it is LTSR for 6 years with 4.18.11 was 2 years. 

I created an alias called CentVer for rpm -q centos-release: 

 alias CentVer=”rpm -q centos-release”

CentVer
centos-release-7-6.1810.2.el7.centos.x86_64
 

I created a file server with SAMBA share for a second CentOS 7 server. 

As of 2.15.2018,  I have phased out my CentOS7 WP server.   The server was slow to backup compared to Ubuntu in VEAAM.   It was more complex putting new SSL Certificates on.    I created two new WP Servers in Ubuntu 16.04.5.   I migrated all the web sites to them from this server.
