enabling accelerated networking on all created interfaces
separating probes for the LB to work on 80 and 443 respectively fixes Azure#131
updating nginx to wait for moodle mount with ssl cert Azure#130
moved t-shirt sized deployments into a table
added info on SSH key generation
added notes about hardcoded SKUs in the pre-defined templates
small tweak re: SSH key pair requirements for Azure
setup_nfs_ha.sh: Added static port assignments to NFS to allow access through a loadbalancer. Ports 111 (TCP/UDP), 2049 (TCP/UDP), 2000 (TCP/UDP), 2001 (TCP), and 2002 (UDP) are the ports required.
In newer versions of Moodle we've observed that the language option changed to en from en_US, this commit aims to fix that.
Making sure we are using local disks for caching Moodle configuration.
Allowing the nginx webserver a higher number of open files.
Making sure we are capturing all of the commands output for our setup script.
In order to decrease the amount of time we are taking for installating packages we've consolidated it in a single command adding quiet options to the apt command.
Adding network kernel parameters and enabling tuned with the throughput-performance profile.
Allowing (mostly) network irqs to be scheduled on the last two vcpu cores.
Increasing allocated memory to 4096MB, increasing the minimum number of threads to 1000 and lowering the delay for creating a thread.
In order to speed up the copying process rsync code was replaced by azcopy.
Adding tuning options for nginx and php-fpm in order to increase performance under load.
This commint will add two public IPs used for outgoing LoadBalancer connections in order to improve overall number of ephemeral ports used by the VMSS when scaled to a higher number of instances.
Scaling sooner with a number of two instances the VMSS webservers.
Improving the overall install process
Azure infrastructure optimization
Webserver fixes and tuning settings
After installing Moodle we are setting the local root directory of the application to be used for caching certain files. Those files need to be owned by www-data.
Fixing Moodle directory permissions
Adding code to deal with nfs type backend storage Signed-off-by: Adrian Joian <ajoian@microsoft.com>
In order to improve overall performance multiple outbound IPs have been added to the ARM templates therefore a switch to the Standard Loadbalancer SKU is required. Signed-off-by: Adrian Joian <ajoian@microsoft.com>
A couple of fixes related to performance and bugs
Workload builder service can migrate(lift & shift) Moodle application running on on-premises VMWare infrastructure to Azure. Workload builder service uses ARM templates from this Moodle repo to prepare the infra in Azure. Below changes are made in this repo to support migration flow: - Added migration specific entry-point/wrapper template which will invoke main template with appropriate parameters. - Added another wrapper template to create file-share storage account. In migration flow, the Moodle code/config/data will be migration from on-prem to azure file-share as 1st step before creating complete infrastructure. - Added few parameters to azuredeploy template to support migration flow. - Changes to install_moodle.sh to skip fresh Moodle installation commands. And also added couple of helper functions to update Moodle config settings in the migrated config file.
Using 'Standard' LoadBalancer SKU for migration scenario as well, align to other fresh deployment scenarios.
Migration flow uses assessment based VMSS sku and not all of them support Accelerated Networking. By default, Accelerated Networking will be disabled in migration flow and enabled as per need.
