Virtualmin Setup DigitalOcean

phenomlab

@Hari good. What’s this going to be for out of curiosity ?

Hari

@phenomlab we have bunch of subdirectories (domain.com/ask, news…) moving them to subdomains (news.domain.com)

once everything works perfectly we may stop using CW

phenomlab

@Hari sounds like a good plan.

Hari

@phenomlab this gonna be a production build. which mySQL option do you suggest? flarum, and 3 to 4 wordpress sites should i go with 1GB MySQL option? we can change this later right?

4GB ram 2vCPU AMD

Edit: i went forward with 1GB MySQL allocation option

phenomlab

@Hari yes, this should be fine.

Hari

@phenomlab one quick question

host.domain.com virtualmin main domain used during setup (host)
site.domain.com virtual server created in virtualmin

i have lets encrypt certificates for both subdomains

CF A name record is proxed, both sites are opening

but when i try to access Virtualmin panel by using host.domain.com:10000 it is not opening

but IP:10000 is working

what am i missing?

is CF preventing port access?

phenomlab

@Hari said in Virtualmin Setup DigitalOcean:

is CF preventing port access?

Yes, but not at the port level. The reason for this is that CF is handling the DNS side of things so when you try to access using your browser, it’s going to resolve to the address in DNS that resolves to CF.

There’s a number of choices depending on your scenario.

The most common approach is to create a page page rule that bypass the CF proxy and allows direct access. The issue here of course is that the free plan on CF only allows a small amount of ports, so you’d need to change the VirtualMin listener port to something else dish as 8443 which is routable in the free plan. You can change the VirtualMin port as explained here

Another approach is to use a management station that has access, and then create a HOSTS file entry that contains a mapping from hostname to IP that overrides the DNS but only for your machine. The preferred order of resolution means host files are read before DNS, and if a match is found then that is used and DNS is ignored.

The drawback with this is that you’d need to make this change on every single machine where you wanted to gain access. Not insurmountable, but quite clunky if you frequently used multiple machine or your phone to get access.

The last method, which is by far optimum is to use a vacant or unused domain to access VirtualMin. I do this myself, and it just means that this domain has no other purpose other than to manage the VPS. In other words, it’s not used for web hosting etc. You can still host the DNS in CF, but you’d then need to ensure the proxy is disabled.

@phenomlab as suggested i have made a few changes

changed my port
changed my host domain from host.domain.com to hos.domain2.com for extra CF page rules

how can i disable others accessing my IP?
instead of using hos.domain2.com to manage virutalmin can i directly use my IP to access virtualmin?
if i proxy or deny direct access to my IP how to give FTP access to one of my admin? as currently we use IP
they need to access using FTP:hos.domain2.com?

should i proxy hos.domain2.com at CF? currently i can not access Virtualmin using port how to add page rule to allow my port

phenomlab

@Hari said in Virtualmin Setup DigitalOcean:

how can i disable others accessing my IP?

Can you clarify this part ? Are you looking to hide the real IP behind CF ?

@Hari said in Virtualmin Setup DigitalOcean:

instead of using hos.domain2.com to manage virutalmin can i directly use my IP to access virtualmin?

Yes, if you aren’t worried about certificate errors

@Hari said in Virtualmin Setup DigitalOcean:

should i proxy hos.domain2.com at CF? currently i can not access Virtualmin using port how to add page rule to allow my port

No, do not proxy it. As soon as you do that, DNS will resolve at CF and not the actual server itself.

Hari

@phenomlab i thought once i set up the host domain i no longer need to access Virtualmin using IP. later realized that is not how it works.

how do i install PHPmyadmin to all servers (domains)? … right now i had to do it manually for each and every domain

though i install phpmyadmin for one domain it is not working, i have tired restarting server and all.

phenomlab

@Hari What is in the error log ? Typically, you’d only need to install phpMyAdmin once and as long as it can see your MySQL server and databases, this should be fine.

That’s a HTTP 500 error which indicates an issue on your side.

Hari

@phenomlab i messed the server, now i can not delete and reinstall.

i have created subdomain1, 2, 3 as main servers instead of creating domain and adding them as sub servers. during this process, i requested for more than 5 let’s encrypt certificates and reached the daily limit. Now i have manually bought one certificate from CF Origin Certificate for 15years and installed it for the main domain

moved all servers as sub servers now i see 403 error

i hope i do not have any SSL issues all i get is 403 for 3 subdomains how can i fix it?

Forbidden
You don'\t have permission to access this resource.

i did not move my main domain yet - planned to move after 1week

phenomlab

@Hari what’s in the NGINX error logs for each of these domains ? Looks like a permissions issue to me

Hari

@phenomlab where do i find it? i think i am not using it

phenomlab

@Hari you have the apache build. In that case, can you post one of the virtualhost configs (for one of the domains)

Hari

@phenomlab where can i find it? sent PM

phenomlab

@Hari

https://www.hostwinds.com/tutorials/edit-apache-conf-files-virtualmin

phenomlab

Can you post the configs here remembering to redact sensitive information, and also use the code markers (three backticks) as this makes it much easier to read rather than standard text in a PM.
