Server management¶
How to setup a DNS Cluster¶
If you are looking for the options to minimize DNS-related downtime or the way to manage dns across all server you have, you might consider to set up dns cluster.
- Create user dns-cluster on a server which will be used as dns slave
- Run following command on a master
v-add-remote-dns-host slave.yourhost.com 8083 admin p4sw0rd
Password and host name should be replaced with relevant data of course.
Alternatively you can run on the slave server the following command
v-generate-api-key
This will generate an API key. Replace the username "admin" with the generated key. This will keep the ability to change the admin password without issues in the future.
v-add-remote-dns-host slave.yourhost.com 8083 api_key
This way you can set up master->slave or master-master-master cluster. There is no limitation on how to chain dns servers.
How to setup a remote database server¶
- It is assumed you already have your second server up and running
- On your Hestia Server run the following command
v-add-database-host mysql new-server.com root password
Mysql maybe replaced by the PostgreSQL
- To make sure database has been added run following command
v-list-database-hosts
How do Web templates work?¶
Warning
Modifying templates could cause errors on the server and services that are not able to reload or start.
Every time you will rebuild the user or domain the config files of the domain will be over written by the new templates. This is done by default during update of HestiaCP or it can be initiated by the admin or by modifying settings by the user.
The templates can be found in the /data/templates/ directory in the install folder
| Service | Location |
|---|---|
| Nginx (Proxy) | /usr/local/hestia/data/templates/web/nginx/ |
| Nginx - PHP FPM | /usr/local/hestia/data/templates/web/nginx/php-fpm/ |
| Apache2 (Legacy / mod-php ) | /usr/local/hestia/data/templates/web/apache2/ |
| Apache2 - PHP FPM | /usr/local/hestia/data/templates/web/apache2/php-fpm/ |
| PHP-FPM | /usr/local/hestia/data/templates/web/php-fpm/ |
When editing it is the best practice to copy the template before editing. As the default templates will reset after update of HestiaCP
cp original.tpl new.tpl
cp original.stpl new.stpl
cp original.sh new.sh
Note
Modifying any default templates can cause issues in the future as there are commonly overwritten during updates.
When you are done modifying enable the template with the selected domain from the control panel.
After modifying existing template you need to rebuild user configuration. This can be done using v-rebuild-user command or bulk operation in the web interface (drop down list on a "User" page).

How can I change settings for a specific domain¶
With the switch to PHP-FPM there are currently 2 different ways.
1# Using user.ini in the directory 2# Via PHP-FPM pool config
Config templates for the PHP pool can be found in
| Service | Location |
|---|---|
| PHP-FPM | /usr/local/hestia/data/templates/web/php-fpm/ |
Due to the fact we use multi PHP we need to recognise the PHP version to be used. There for we follow the following naming.
YOURNAME-PHP-X_Y.tpl
There X_Y is your PHP version
How do DNS templates work?¶
DNS templates can be found in
| Service | Location |

| %domain% | domain.tld | Domain of the user |
| %time% | 12:00:00 | Time of creation |
| %date% | 01-01-2020 | Time of creation |
Templates can support up to 8 name servers with with %nsx% x could be up to maximum of 8
Where can I find more information about the config files¶
A good starting point for every software check the creator

How to install additional PHP packages / Modules¶
apt-get install php-package-name

IPTables How can I allow/deny an IP to all ports¶
By default after each restart Hestia will clear the current iptables
To allow an IP to all ports (Or block)
Use the following command
v-add-firewall-rule ACTION IP PORT [PROTOCOL] [COMMENT] [RULE]
v-add-firewall-rule 'accept' '123.123.123.123' '0' # Port 0 matches all ports
Also via interface it is possible just enter 0 as port number
