Concerning phpMyAdmin : do you install it on all web server or just one ?

but for your multi server setup : do you install phpmyadmin (so with nginx or apache) on database server ?

 

ok : it's WORKING , you force me to ... think stronger ! (and thanks again)

No phpyadmin install on other servers (db or web) , just on the first one , web1. (with our panel !)
panel url : https://panel.domain.com:8080/

in System \ Main config ==> https://panel.domain.com:8080/phpmyadmin/
Then edit : nano /etc/nginx/sites-enabled/000-ispconfig.vhos
comment out : phpmyadmin part.
Finaly edit : nano /usr/share/phpmyadmin/config.inc.php

with

/**
* Second server
*/
$i++;
/* Authentication type */
$cfg['Servers'][$i]['auth_type'] = 'cookie';
/* Server parameters */
$cfg['Servers'][$i]['verbose'] = 'db1.domain.com';
$cfg['Servers'][$i]['host'] = '10.100.100.1';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['AllowNoPassword'] = false;
$cfg['Servers'][$i]['AllowRootPassword'] = false;
$cfg['Servers'][$i]['hide_db'] = 'information_schema';

 

i'm reading that in pdf manual : "Don't forget to reload nginx afterwards:"
when copy / paste snipet (ie. phpmyadmin nginx) : must i log to server then systemctl restart nginx ? (or panel will do it for us ?)

 

No agree, with not separate web server and database !
VM to VM Network traffic, same node : "Yes, we use a linux bridge device."
Proxmox inside. (our web1 and db1 are always on the same nodes)

 

ok, that a good news ;-)thank you till.

 

Sum up (nginx setup) , what have been done :

1 - ISPCOnfig : create DNS : A (or CNAME) record , panel.domain.com pointing on public IP of your web server

All this must be done by chosing webserver (in ispconfig) where you have installed phpMyadmin or ssh to this server :

2 - ISPCOnfig : Create website "domain.com" + let's encrypt + ssl php-fpm + auto-subdomain " *. "
3 - SSH WEBSERVER : Comment out this in /etc/nginx/sites-enabled/000-ispconfig.vhost

location /phpmyadmin {
root /usr/share/;
index index.php index.html index.htm;
location ~ ^/phpmyadmin/(.+\.php)$ {
try_files $uri =404;
root /usr/share/;
include /etc/nginx/fastcgi_params;
fastcgi_pass unix:/var/lib/php7.3-fpm/ispconfig.sock;
fastcgi_param HTTPS on;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $request_filename;
}
location ~* ^/phpmyadmin/(.+\.(jpg|jpeg|gif|css|png|js|ico|html|xml|txt))$ {
root /usr/share/;
}
}
location /phpMyAdmin {
rewrite ^/* /phpmyadmin last;
}​

4 - ISPCOnfig :: set "System\ Main config \ php URL to "https://panel.domain.com:8080/phpmyadmin/"
5 - SSH WEBSERVER : Edit your "/usr/share/phpmyadmin/config.inc.php" (config of php

6 - your panel is ok here : https://panel.domain.com:8080/phpmyadmin/

Now when you create database you could administrate it through ISPconfig via phpmyadmin icon on the right of the database name.

Note : this how to suppose that you have dedicated Databse server (here db1,db2 and db3)
