Setup few CentOS/Plesk settings

-------------------------------------- VPS configuration: Hostname: [login to view URL] IP address originally assigned by my hosting company: [login to view URL] Current IP address of [login to view URL] domain: [login to view URL] OS: ‪CentOS Linux 7.1.1503 (Core)‬ Product: Plesk Onyx Version 17.5.3 Update #4 -------------------------------------- - Make the IP [login to view URL] shared IP - Move all domains from IP [login to view URL] to shared IP [login to view URL] - Server's main IP address assigned by the hosting copany was originally [login to view URL] and the parent's DNS servers are set to this IP, and my main domain is "[login to view URL]", so please change the IP address for the domain "[login to view URL]" back to [login to view URL] - Make the IP [login to view URL] dedicated IP - Update SSL certificates for all domains that were moved to diffent IP adresses (Let's Encrypt certificates are ok) - Be careful and double-check the DNS records for domains, because some of them contain manually added DNS entries and they need to point to the right IP, after you moved the domains to a new IP address. - Setup rDNS for all IPs correctly (I have only 5 IPs on this server) - When I create subdomains, Plesk creates DNS entry only for "subdomain.<domain>", but it also needs to create DNS entry for "www.subdomain.<domain>" - Setup the domain template in Plesk correctly. If I create a new domain, the DNS must be automatically set. There must be all DNS entries + MX of my server + MX of Google + all records needed to successfuly deliver emails (SPF, DKIM, DMARC, etc). - Correctly setup emails signing for all domains (SPF, DKIM and DMARC for emails sent directly from my server + emails sent through Google MX servers) <--- I think this is already done, but please prepare to fix it if it's not done properly - I will use "[login to view URL]" to see the score and it must be at least 8/10 (preferably 9/10) - Move the webmail URL for all domains from address "webmail.<domain>/<webmail_app>/" to "<domain>/<webmail_app>/" because the Let's Encrypt SSL certificate doesn't cover "webmail.<domain>", just "www.<domain>" and "<domain>" - Also make sure that if the customers click the webmail icon in their Plesk account, it points them to the correct URL "<domain>/<webmail_app>/" and not the old "webmail.<domain>/<webmail_app>/" - Be careful, because the domains "[login to view URL]", "[login to view URL]" and "[login to view URL]" have MX records set to use Google MX servers (this needs to stay there, I'm actively using Google mail servers for these domains) - Install and correctly setup Google PageSpeed modules "[login to view URL]" for Apache and Nginx - Yesterday I received 2 warnings in Google Webmasters Tools for the domain "[login to view URL]", please just check if there's really something wrong with the SSL certificate (in my opinion the certificate is ok) 2.5.2017 "SSL/TLS certificate does not include domain name [login to view URL]" 2.5.2017 "Self signed SSL/TLS certificate for [login to view URL]" - After all these server changes, please manually check that the domains "[login to view URL]", "[login to view URL]", "[login to view URL]" and "[login to view URL]" work fine, these are my own domains + there are important eshops. Also check that the emails are sent fom these domains correctly.
