Production Install - Azure¶

Tip

All shell commands are run as root.

Create an Azure Database for MySQL.

MySQL > 5.7.8 database instance with 4CPU x 16GB RAM and 500GB storage
Set the MySQL configuration parameter max_allowed_packet to 256M.

Set the following parameters as part of the parameter group: STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION.
Create the databases and users on the database instance by running the following SQL:
CREATE DATABASE scalr;
CREATE DATABASE analytics;
CREATE USER 'root'@'%' IDENTIFIED BY '<copy root password from scalr-server-secrets.json>';
CREATE USER 'scalr'@'%' IDENTIFIED BY '<copy scalr password from scalr-server-secrets.json>';
CREATE USER 'repl'@'%' IDENTIFIED BY '<copy repl password from scalr-server-secrets.json>';
GRANT ALL PRIVILEGES ON analytics.* TO 'root'@'%';
GRANT ALL PRIVILEGES ON scalr.* TO 'root'@'%';
GRANT ALL PRIVILEGES ON analytics.* TO 'scalr'@'%';
GRANT ALL PRIVILEGES ON scalr.* TO 'scalr'@'%';
GRANT ALL PRIVILEGES ON analytics.* TO 'repl'@'%';
GRANT ALL PRIVILEGES ON scalr.* TO 'repl'@'%';

Create an instance for the Scalr App Server.
- A single server with minimum 4CPU x 16GB RAM and 50GB storage mounted on /opt/scalr-server/
- OS: Ubuntu 18.04, RHEL/CentOS 8.x, or Amazon Linux 2

On the Scalr App Server, get the scalr-server package and install it:

# For Debian:
curl -s https://<token>:@packagecloud.io/install/repositories/scalr/scalr-server-ee-staging/script.deb.sh | sudo bash
apt-get install scalr-server

# For RPM:
curl -s https://<token>:@packagecloud.io/install/repositories/scalr/scalr-server-ee-staging/script.rpm.sh | sudo bash
yum install scalr-server

On the Scalr App Server, run the following when prompted:
scalr-server-wizard
This command creates the /etc/scalr-server directory and the scalr-server-secrets.json file.
On the Scalr App Server create/copy the following:
1. Your Scalr license file to /etc/scalr-server/license.json.
2. Your SSL Cert to a suitable location, e.g. /etc/scalr-server/organization.crt
3. Your SSL key to a suitable location, e.g. /etc/scalr-server/organization.key

On the Scalr App Server, edit the Scalr configuration file /etc/scalr-server/scalr-server.rb to match your set up. This example can be pasted to the file and edited. Make sure to update the values with the actual values for you installation. You will need to check and/or update the following:

proxy[:ssl_cert_path]
proxy[:ssl_key_path]
routing[:endpoint_host]

app[:mysql_scalr_host]

enable_all true
product_mode :iacp
mysql[:enable] = false

# Mandatory SSL
# Update the below settings to match your FQDN and where your .key and .crt are stored
proxy[:ssl_enable] = true
proxy[:ssl_redirect] = true
proxy[:ssl_cert_path] = "/etc/scalr-server/organization.crt"
proxy[:ssl_key_path] = "/etc/scalr-server/organization.key"

routing[:endpoint_host] = "iacp.organization.com"
routing[:endpoint_scheme] = "https"

#Enter the IP or domain name of your MySQL instance
app[:mysql_scalr_host] = MYSQL_SERVER_HOST
app[:mysql_scalr_port] = 3306

#Add if you have a self signed cert, update with the proper location if needed
#ssl[:extra_ca_file] = "/etc/scalr-server/rootCA.pem"

#Add if you require a proxy, it will be used for http and https requests
#http_proxy "http://user:*****@my.proxy.com:8080"

#If a no proxy setting is needed, you can define a domain or subdomain like so: no_proxy=example.com,domain.com . The following setting would not work: *.domain.com,*example.com
#no_proxy example.com

####The following is only used for optional configuration as needed.####
#app[:configuration] = {
#:scalr => {
#  "tf_worker" => {
#      "runner" => {
#            "run_time_limit": 720  # 12h #Default is 60/1hr,
#           "docker" => {
#              "device_read_iops" => 500, #Limit read rate (IO per second) from the device(s). This option will only work in conjunction with `tf_worker.runner.docker.storage_devices` option. Disabled by default.
#              "device_write_iops" => 500, #Limit write rate (IO per second) from the device(s). This option will only work in conjunction with `tf_worker.runner.docker.storage_devices` option. Disabled by default.
#              "storage_devices" => ["/dev/sda"], #The list of block devices for the `device_read_iops` and `device_write_iops` options. The device(s) must exist on the Docker node. Usually, there should be one device on which the `/opt/scalr-server/` directory is mounted, unless you are using custom docker daemon with non-default configuration. Warn: The non-existent device in this list will break the Terraform Runs. Default is [].
#              "mem_limit" => 256, #Memory limit in megabytes. Optional, default value: 256 (mb).
#              "cpu_period" => 100000, #Limit CPU CFS (Completely Fair Scheduler) period (in microseconds). Optional, default value: 100000 (μs).
#              "cpu_quota" => 50000 #CPU time that the container can get in a CPU period (in microseconds). Optional, default value: 50000 (μs).
#           }
#       }
#    }
#  }
#}

On the Scalr App Server, reconfigure Scalr:

/opt/scalr-server/bin/scalr-server-ctl reconfigure

You can now log into Scalr by putting the hostname that is listed as your endpoint in the scalr-server.rb into a browser. To log in the first time, please find the admin password in the /etc/scalr-server/scalr-server-secrets.json file. The username is admin.

"app": {
  "admin_password": "password123"
