Hi I'm in process of splitting up almost single ISPconfig, I have though been using 4 DNS server master + 3 replicas, now I'm thinking of Master + Master replica, redundant: web, mail, DNS, webmail, maybe SQL if it is of benefit. I have already set up geo-divided locations ping about 40 mS ping and 1GBit I run V-cloud over that with out problems so connectivity is OK. My plan is setting up servers by multi server setup directions an migrating all to New master then Migrate web to first web server and have ether Hi-availability do the replication to secondary Webserver, same for the others. Ho ever I have trouble migrating with the migrating tool it seems that I'm mis reading some instructions on how to migrate limited services, I have done several tests but some how it does not do it cleanly ad not all attempts return usable results. Also is it better to have SQL on each server to serve locally and replicate from master or one master SQL on either geolocation. I will set HA ip proxy for mail and web in firewalls. Regards Stefan
The former is the ISPConfig recommended way ever since. Never heard of the latter. That are a lot to process but could be worth it, so good luck with that. I am currently leaning to use Proxmox for backup, HA and redundancy.
You can find a setp-b-step tutorial here: https://www.howtoforge.com/tutorial...-confixx-plesk-to-ispconfig-31-single-server/ The tutorial contains a detailed list of command-line options in the last chapter that you can use to limit a migration to a specific service. Always run the tool on the old server and let it connect to the new master server, the tool will then show you all available nodes of the multiserver setup to choose where you want to migrate the service to. Always use dry-run first and then check the output and migrate.log to verify that the options you used to limit the service were correct.
Local databases are way fastre and that#s why we use that setup. See ISPConfig multiserver installation guides.
I'm just tying to confirm that I get this right. 1. First set up all servers according to https://www.howtoforge.com/tutorial/ispconfig-multiserver-setup-debian-ubuntu/ 2. Then migrate all of the single-server to new Master server all services to one new master that is the control panel as well (I tried to migrate with out DNS and that resulted in no DNS control panel) 3. Add other new severs to new master server 4. Migrate mail data from old master to first Mail server, first webserver...... that will in turn populate the sibling servers 4a. If I have 2 mail servers can I use them with alternating priorities between domains to load balance i.e. mx1 pri 10 mx2 pri 5 for domain1 and vice versa for domain2 ? 4b. Will they sync both ways ? 5. Do I need to set up apache and phpmysql on all servers or am I able to connect to the SQL's from control panel server, I'm asking since it seems that my DNS replicas on far geo location from master server seem to retain old settings and revert to them now and then, I have had to edit the zone files every time for relevant domains, quite tedious. I'm only asking since all the associated references are close to 300 pages
No, the steps are: 1) Install your complete new multiserver setup with all servers. 2) Run the migration tool on each old server one after another, let it connect to the new master, and then choose in the dialog that appears on which of the new nodes the data shall be migrated.
