Access Webmin with IPv6 address

I tried a IPv6 only VPS. It has no IP v4 address.

It is always error  connection when I tried to use an IP v6 to connect it.

Here is some new knowledge for me.

Use a pair [] around the IPv6 address when using it in the Browser address .

The correct format is: https://[2001:19f0:8001:ae7:5400:1ff:fe93:a764]:10000

 

To enabled IPv6 support.

1) /etc/webmin/miniserv.conf

add a line

IPv6 =1

2) Install Socket6 perl module

apt install libsocket6-perl

Then restart webmin service.

Now I can enter the webmin which is IPv6 only webmin.

How to install SSL certificate in Webmin

It is a little bit tricky when I install SSL certificate in Webmin. Here is a how-to of installation of it.

Now Webmin is version 1.710, on CentOS 6.5.

The SSL certificate is issued by Comodo.

The very important part is the key and certificates themselves. I have all these files from gotssl.com. But I know know how to combin them or which one is the correct file.

So, make two files first.

1) Combine server private key and certificate into one file.

new_miniserv.pem


<code>-----BEGIN PRIVATE KEY-----
(Contents of private key)
-----END PRIVATE KEY-----
-----BEGIN CERTIFICATE-----
(Contents of SSL certificate: your_domain_name.crt)
-----END CERTIFICATE----- </code>

your_domain_name.sha256.ca-bundle

It is for chained certificates.


(contents of COMODORSADomainValidationSecureServerCA.crt)

(contents of COMODORSAAddTrustCA.crt)

Save both files into /etc/webmin/

2) Sign in webmin with http protocol.

Goto, Webmin > Webmin Configuration > SSL Encryption

Filling the fields of Private Key and Additional certificate files.

And also choose Yes on “Enable SSL if available? “.

Click Save and it works right away.

webmin-ssl-config

Then when you need to access webmin. The URL is https://your_domain_name.com:10000

No more warning of self-signed certificate.

 

How to manage MariaDB in Webmin

It is easy to use Webmin to manage VPS, including MySQL server.  But it is not working with MariaDB default.

The webmin MySQL server shows error as below:

mariadb-webmin

It can not find the path of command to start and stop MariaDB and also config file of MariaDB server.

So click module configuration and change:
Command to start MySQL server: /etc/init.d/mysql start
Command to stop MySQL server: /etc/init.d/mysql stop
MySQL configuration file: /var/lib/mysql/my.cnf

If your MariaDB server configuration file is not in this location, double check your setting and enter the correct value.

After saving, it will ask for your username and password to connect your MariaDB server.  Enter them and save.

mariadb-settings

At this step, you can add database or do other tasks in Webmin.
