Linode official centmin mod Linode stackscript

Thanks to @Jens Sogaard inspiration, I have created a Centmin Mod 123.09beta01 CentOS 7 Linode stackscript now. It has been published to Linode's public stackscript library.

• Centmin Mod stackscript profile - where you will find all publicly published Centmin Mod stackscripts in future.
• How to use StackScript Guide
• Linode Stackscript docs at Automate Deployment with StackScripts

Updated stack script (1st post screenshot) with extended options you can choose

Including pushover.net notification support when stackscript completes

masked the hostname in example push notification to my Android mobile

 

Added ability to whitelist IP addresses in CSF Firewall + add SSH Public key to Linode VPS

 

How To Use Linode StackScript To Deploy Centmin Mod LEMP Stack

Below is illustrative guide on deploying Centmin Mod LEMP stack via official Linode StackScript. You can use my referral code for Linode here.

Step 1. Add a Linode and select your VPS plan and geographic location


Step 2. Go to your created linode manager dashboard which will not have any configuration profiles yet. Usually, you would click 'Deploy an Image' to select CentOS 7. But you can deploy via Linode StackScript by selecting 'Rebuild' link.



Step 3. On rebuild page you can either select an OS image, disk size, swap size and root password or using 'Deploying using StackScript' link. Click that link instead.



Step 4. On StackScript library page, search via Keywords = centminmod and find the official centminmod/centminmod Linode StackScript and click that link.



Fill out the details on StackScript page and hit Rebuild button



Step 5. You will be brought back to new Linode's dashboard and see that a configuration profile = centminmod has been selected. Server status = Powered Off still. So need to hit Boot button to power on your Linode VPS.



Step 6. Host Job Queue status will show System Boot = Success once booted up. At this stage you can SSH login to your new Linode VPS. The StackScript will be running in background installing and configuring Centmin Mod automatically You can follow, the StackScript progress via the log at /root/stackscript.log

list last 15 lines of log

Code (Text):

tail -15 /root/stackscript.log

if it's complete, the last 5 lines would be

Code (Text):

tail -15 /root/stackscript.log

Thu Aug 10 04:22:20 UTC 2017
Stackscript Setup Complete For host.domain.com
stackscript log: /root/stackscript.log
centmin mod logs: /root/centminlogs

or you can follow log in real time

Code (Text):

tail -f /root/stackscript.log

Step 7. Once StackScript completes Centmin Mod LEMP install, follow the official Centmin Mod Getting Started Guide to the letter

Step 8. You'll also have alot of Centmin Mod install logs themselves located in /root/centminlogs which includes the install.log which has your MariaDB root user password, memcached & zend opcache admin page password and php info location etc.

The install log in this case would be at /root/centminlogs/centminmod_1.2.3-eva2000.09.005_100817-234911_install.log

Updated StackScript to add Nginx vhost and MySQL database setup support

 

Linode StackScripts are listed in the public library by rank sorted by number of deployments StackScripts - Flexible Customization

Thanks to some Centmin Mod users, the Centmin Mod StackScript is moving up the rankings now

Total of 19 deployments where 5 were still active

 

Updated StackScript to support and control Nginx Lua, Brotli and Cloudflare HTTP/2 HPACK Full Encoding patches



and sshd login alert option

 

As far as I know, nope as Linode defines the questions as UDF parameters. But modifying the Linode UDF parameters as traditional bash variables should work.

 

Great time to learn and play with shell scripting seeing that is what Centmin Mod is built upon

• Shell Scripting Part 1-4 from howtoforge.com
• Videocast Shell Scripting by Unixmen.com
• learnshell.org
• shellcheck.net
• explainshell.com online tool
• Understanding and using AWK command
• Advanced Grep Commands Guide
• [Guide] Identify Working Directories in SSH
• How to find files in Linux with find command
• 15 useful sed command tips & tricks
• SSH command keyboard shortcuts
• Sort 'ls' output by time
  
• 3 Ways to Delete All Files in a Directory with Exceptions

 

Yup more folks using or testing official Centmin Mod Linode Stackscript

 

hehe.. good idea to not ignore Centmin Mod related emails. I don't like spam myself so try not to email members unless it's really important

 

Updated Centmin Mod Linode stackscript to disable HPACK cloudflare patch incompatibility with Nginx 1.13.6+ temporarily as well as add march=native control - Beta Branch - add MARCH_TARGETNATIVE option for 123.09beta01 and higher

 

Updated Centmin Mod Linode stackscript to re-enable Cloudflare HTTP/2 HPACK Full encoding patch support as well as add Cloudflare zlib support and soon PHP 7.2.0 default initial install support. If you want to try it out see how to install/use guide in post #5 above.

 

Actually, as at Feb 24, 2018 Centmin Mod 123.09beta01 defaults to GCC 7.2.1 + OpenSSL out of the box now - but yes i need to update stackscript for the same too

edit: just updated Centmin Mod official Linode stackscript for such StackScripts - centminmod/centminmod. Enjoy

 

Been a while since I checked stats for Centmin Mod official Linode stackscript for such StackScripts - centminmod/centminmod
