Secure Sentora With SSLForFree

Sun, 21 Apr 2019 20:23:10 -0400

I have written a quick tutorial on how to secure your Sentora Control Panel with SSLForFree SSL Certificates.

This is a quick tutorial and im just demostrating how i use these certificates for my panel and websites and the tutorial is designed for CentOS 6 Minimal If ive missed anything let me know as i was rushed.

Securing Sentora Panel via SSLForFree

This guide is designed for CentOS 6 Minimal

Step 1: Install Sentora once installed follow this guide.

Step 2: Login to your server via SSH using Putty

Step 3: Install OpenSSL and Mod_SSL using the following commands:

OpenSSL: yum install openssl

Mod_SSL: yum install mod_ssl

Once this is complete resart apache using service httpd restart

Step 4: Login to your server using FlashFXP or SFTP using FTP/SSH port 22 with your servers root username and password

Step 5: Once logged in go to /etc/sentora/panel/ and create a new folder named .well-known inside this folder create another folder called acme-challenge.

Once this is comple your full path should be /etc/sentora/pane/.well-known/acme-challenge/

Step 6: Go to https://www.sslforfree.com and create a new domain ie:panel.domain.com (yourdomain.com/panel) and click Manual Verfication and download your verification key (do not close your browser window).

Step 7: Upload this downloaded verification key to /etc/sentora/panel/.well-known/acme-challenge/ once this is done go back to the start SSL Page and click the verification link, Upon clicking this link it should take you to panel.yourdomain.com/obsecureverificationkey (random letters and numbers)

Step 8: Once step 7 is complete download your SSL Certificate and extract the SSLforFree.zip file, Inside this folder you will have three (3) files one cerificate, one private and one bundle (we are only going to use the Cerificate.crt and Private.key files)

For ease of use please rename the certificate.crt and private.key files to panel_domain_com_certificate.crt and panel_domain_com_private.key this is to just keep others ssl certificates seperate and easier to find when you add more later.

Step 9: With these files downloaded and renamed upload the panel_domain_com.crt to /etc/pki/tls/certs/ and upload the panel_domain_com_private.key to /etc/pki/tls/private/

Then go to /etc/httpd/conf.d/ and download your ssl.conf file.

Step 10: Open your newly downloaded ssl.conf file with WordPanel and scroll down to the bottom and add the following replacing with your details:

NameVirtualHost serverip:443

ServerName panel.domain.com
ServerAlias panel.domain.com
DocumentRoot /etc/sentora/panel/
SSLEngine on
SSLCertificateFile /etc/pki/tls/certs/panel_domain_com_certificate.crt
SSLCertificateKeyFile /etc/pki/tls/private/panel_domain_com_private.key

and save your new ssl.conf and reupload replacing your current ssl.conf file.

Step 11: go back to putty and restart your apache with service httpd restart if everything went well your with an OK resart once done open your browser and go to https://panel.domain.com and your panel should be secured via SSL

How to install mod_pagespeed on Sentora

Sat, 25 Nov 2017 15:23:35 -0500

First of all, I would like to tell you, I have used mod pagespeed and have installed on VPS so I would point out how to do it. I only did for Centos 6 for apache server. I highly recommend that first you take backup of your website so if anything gets messed up, you have everything in your hand to make your site work again.

Precaution : KVM - if you have SSL installated with 443 port ( needed in apache setting), you might probably see error while restarting your httpd. So I recommend mod_pagespeed installation on sentora just after sentora installation. It will take your whole server down.

I didn't face above issue with OpenVZ server even when SSL was already installed. ( but better install it just after fresh sentora installation before you upload your contents)

Method:

Visit https://www.modpagespeed.com/doc/download ( download the file according to your vps setting )

2. Upload the downloaded file to "root" folder of your server.

3. Run the following command :

sudo yum install at
sudo rpm -U mod-pagespeed-*.rpm

In case your installation shows key missing error. Use this command : sudo rpm --import https://dl-ssl.google.com/linux/linux_signing_key.pub

4. Run the following command : sudo /etc/init.d/httpd restart

You are done.

[How To] Update phpMyAdmin to latest version 4.7.4

Tue, 17 Oct 2017 13:04:16 -0400

Before we begin. The required update to phpMyAdmin 4.7.4, you will HAVE to update your php to version 5.5 or above here is a thread that can help you get to php5.6.31 with suhosin patch.

Install php version 5.6.31 --> #4131
After you have successfully update to php version 5.6.31 you can now update your phpMyAdmin to v4.7.4

Code:
//first goto apps directory
cd /etc/sentora/panel/etc/apps 
//then we grab the latest phpmyadmin from there site
wget https://files.phpmyadmin.net/phpMyAdmin/4.7.4/phpMyAdmin-4.7.4-all-languages.zip
//now we unzip it
unzip -q phpMyAdmin-4-*
//before we go any further we MUST copy the current config.inc.php file to our home dir
cp /etc/sentora/panel/etc/apps/phpmyadmin/config.inc.php /home/
// delete the phpmyadmin folder 
cd ../
rm -rf phpmyadmin
//now mv the phpMyAdmin-4.7.4-all-languages folder to phpmyadmin:
mv /etc/sentora/panel/etc/apps/phpMyAdmin-4.7.4-all-languages /etc/sentora/panel/etc/apps/phpmyadmin

Now login to your phpmyadmin and the version should be the same as the below image:

[How To] Update from PHP v5.4.16 to v5.6.31 (Includes suhosin patch) [CentOS]

Tue, 17 Oct 2017 12:46:55 -0400

Lets begin by logging into your panel using ssh, then enter the following commands:

Code:
//check current version
php -v
// install epel && update
yum install epel* && yumupdate
//Add CentOS 7 repo
wget http://rpms.famillecollet.com/enterprise/remi-release-7.rpm
//run it && update
sudo rpm -Uvh remi-release-7*.rpm && yum update
//update php to 5.6
yum --enablerepo=remi,remi-php56 update

Now the above handles the installation of php5.6, although the following is the main part and is A MUST for Sentora Panel.

Rebuild Suhosin

Code:
cd /tmp
wget -nv -O suhosin.zip https://github.com/stefanesser/suhosin/archive/suhosin-0.9.37.zip
unzip -q suhosin.zip
cd suhosin-suhosin-0.9.37
phpize &> /dev/null
./configure &> /dev/null
make &> /dev/null
make install
// now reboot using
reboot
//after reboot do
php -v

You should get the following output:

[How-To] Install the perfect Sentora server using CentOS 7

Tue, 17 Oct 2017 10:55:05 -0400

NOTES: I will be using a virtual machine for this installation process, if you bought a dedicated server then simply login to your account and install CentOS 7 Minimal. That's if they support CentOS.

How to install CentOS 7 (for new users):
CentOS 7:

Download CentOS 7 Minimal from http://centos.mirror.ac.za/7/isos/x86_64...l-1708.iso

Installation:
1: Select the appropriate language

2: Fix any issues, Enable your network and set the date&time.

Secure your server with a secure and lengthy password (try to make it as random as possible).

3: Login to your server.
4: Now we need to set a static ip for the server.

Code:
//before we set the static ip lets get a few essentials 
sudo yum install nano openssh -y
//now the fun part setting up a static IP for your server
sudo nmcli dev
//that should display either display "eth0" or"enpos3"
//I am using enp0s3
//jump to the network scripts folder
cd /etc/sysconfig/network-scripts/
ls
//do ls and it will display the file we are going to edit "ifcfg-enp0s3"
nano ifcfg-enp0s3

SIDE NOTE: if you are going use it in a Virtual Machine you will NEED to set the network type to "bridged adapter".

Now edit the following in the ifcfg-enp0s3 file:

Previous: BOOTPROTO="dhcp"
Change To: BOOTPROTO="static"
Hit Enter and in the next line enter your details

Code:
IPADDR=192.168.x.x
NETMASK=255.255.255.0
NETWORK=192.168.x.x
GATEWAY=192.168.x.x
DNS1=8.8.8.8
DNS2=8.8.4.4
NM_CONTROLLED=no //must be set as NO

NOTE: to save and exit changes use CTRL+x and then type y and hit enter it will save and close
FYI: DNS ip addresses are for googles dns

End result should look something like this but obviously on your network as I have multiple, I will be using my first network 192.168.1.0 for this as its used for demos etc.

now you need to restart your network for those changes we made to take effect.

Code:
systemctl restart network
//then type 
ip add
//the output will show you if your ip has been set my one displayed 192.168.1.11 as I set it to .11

I usually test if I am able to resolve both domain names as well as ip's

Code:
ping google.com
//if request timed out , something went wrong
ping 8.8.8.8
//same as previous comment

If they both are able to send and receive data, congratulations you have a static ip

Finally, we can begin installing sentora panel.

Step 1: goto the Docs and grab the auto install script.

Code:
//double check the below url with the above link
bash <(curl -L -Ss http://sentora.org/install)

Step 2: login to your panel using ssh or even directly(VM users).
paste the link in the terminal and hit enter

INSTALLATION PROMPTS:
- 1st Prompt: "Please select a continent or ocean."
  2nd Prompt: "Please select a country."
  3rd Prompt: "Is the above information OK?"
  4th Prompt: "Enter the sub-domain you want to access Sentora panel:" //Please Enter the corrent domain name eg: panel.site.tld or sen.site.tld or whateveryouwant.site.tld

If you are able to set the cname as well as the ip you would get "All is ok. Do you want to install Sentora now (y/n)? y"

if your panel does not resolve because you are going to use the current server for your domain and dns management simply force the install when it prompts you to force continue installation.

Give it up to 10+ minutes (depends on internet speed, usually its less than 10minutes) for it to complete.
you will then get the last prompt after it has been installed:
"Restart your server now to complete the install (y/n)?"
enter y and hit enter.

You should now have successfully installed Sentora v1.0.3 using CentOS 7, we are not yet done.

Login to your panel using the details in /root/passwords.txt

Now locate to Domains and add your domain. Note it will not go live until you do the next step.
Goto Dns Manager->select_a_domain_&_hit_enter->click_on"Create Records". //If your dns is managed by cloudflare or any other dns manager this might cause issues.

if you go back to "Domains" in a couple of minutes you should see that your domain is "Live";

Congratulations, You have successfully setup Sentora Panel & Your Domain using CentOS 7 Server.

[How-To/Guide] Update Roundcube, The best way to keep spam away.

Sun, 15 Oct 2017 09:12:37 -0400

Are you a new user to Sentora Control Panel ?, if you are be sure to update your Roundcube if you would like to see a decrease of spam being sent from your server. Well this is my first step after a new install of Sentora V1.0.3 .

So lets have a few other steps before we continue:

1: for this to be succefull, you will need to have a secure password setup for all your emails, clients emails, server "root" user, zadmin user. basically all passwords have to be random as well as above 16 characters.
2: A password that i would call secure would have a minimum of 16 characters and within that 16 chars it must be as random as possible so that you make it tough on hashcrackers as well as the hackers that obtain your hash.
3: Example of a secure ish password: 16 chars --> {nr7 #$(y8CY4unyDCP!Ax@x)=.`kea2x`W$(
4: The above is an example of a random password generated by my prog although there are various other password generators online. such as PasswordGenerator.net which is supprisingly good and you have an option to generate the password using your broswer instead of sending it across the internet to the server.
5: check the current installation of sentora for any issues which is located in the log files.
6: check your version of Sentora v1.0.3 is compatibile with the update.
7: Check if your roundcube(current roundcube version on sentora v1.0.3, roundcube v1.0.4) is functional and you are able to send and recieve mail before continuing with the update.

So lets begin the update/installation progress:

First go to the RoundCube website: and choose which version you would like to install, I prefer using the stable versions.

We are going to upgrade roundcube v.1.0.4 to v1.2.6 and it works with the latest version as well v.1.3.1.

Download the v-1.x.x Complete of roundcube here are the two that work properly at the moment.
v-1.3.1 Complete = HTTPS://github.com/roundcube/roundcubema...ete.tar.gz
v-1.2.6 Complete HTTPS://github.com/roundcube/roundcubema...ete.tar.gz
Login to your server using SSH then enter the following:

Code:
CD /etc/sentora/panel/etc/apps

After that

Code:
//now we need to get the roundcube using the links
wget HTTPS://github.com/roundcube/roundcubemail/releases/download/1.2.6/roundcubemail-1.2.6-complete.tar.gz
//then extract the .tar.gz to apps directory not /webmail
tar xf roundcubemail-1.2.6-complete.tar.gz
//CD into the extracted roundcube folder I'm going to use the * as you could be using any other version
CD roundcubemail-*
//now the main part :: Make SURE that rsync is installed other wise you are going to get a "ERROR500"
//upgrade time ./bin/installto.sh 
./bin/installto.sh /etc/sentora/panel/etc/apps/webmail 
//it will prompt you , before installation simple enter "y"

once the installation is done, do a little clean up you can remove the following folders:
/installer/
/SQL/
IN THE APPS FOLDER /etc/sentora/panel/apps remove
/roundcubemail-1.2.6-complete.tar.gz
/roundcubemail-*

Hi Guys,

I am new to Sentora, I am using Google Cloud Engine with CentOS6 I don't know how to setup subdomain for the sentora installation and for sentora panel.

I am getting this warning message while installing "WARNING: panel.mydomain.tk is not defined in your DNS!" but I already set this subdomain in GoogleCloud engine, like this step:

1. I have installed CentOS6 on Google Cloud Engine
2. And mydomain.tk registered at freenom.com
3. On Google cloud engine -> Networking-> Cloud DNS: created DNS entries for the instance IP and domain like this:

Code:
mydomain.tk    A    300    xxx.xxx.xxx.xxx
mydomain.tk    NS    21600   ns-cloud-c1.googledomains.com
                             ns-cloud-c2.googledomains.com
                             ns-cloud-c3.googledomains.com
                             ns-cloud-c4.googledomains.com
mydomain.tk    SOA    21600  ns-cloud-c1.googledomains.com. cloud-dns-hostmaster.google.com. 1 21600 3600 259
ftp.mydomain.tk    CNAME    300    mydomain.tk
mail.mydomain.tk    CNAME    300    mydomain.tk
panel.mydomain.tk    CNAME    300    xxx.xxx.xxx.xxx
www.mydomain.tk    CNAME    300    mydomain.tk

4. My domain nameserver changed from Freenom according to google....

What I missed here? I already set panel.mydomain.tk for sub-domain. or I need to do anything additional, please assist me on this I am middle of the installation.

Thanks!
