Upgrade Yarnman – Linux Version 18 upgrade

Process to upgrade Linux to version 18. It is strongly recommended to take a snapshot prior to upgrade

1. Download Linux Upgrade Script + Application Patch from Yarnlab web site 

https://yldev.blob.core.windows.net/packages/yarnman-linux-upgrade18-bundle-<Ver>-master-<Build>.tar.gz.sig 

https://yldev.blob.core.windows.net/packages/yarnman-app-<Ver>-master-<Build>.tar.gz.sig

2. Take a Snapshot

3. ssh to yarnman server

CD /opt/yarnlab/yarnman

1. Run The application patch

./scripts/install-yarnman-app.sh yarnman-app-<Ver>-master-<Build>.tar.gz.sig   

Note: this command may require -i at the end depending on source version. It would then be ./scripts/....tar.gz -i        

1. Verify that app installed correctly in Yarnman Administration App Web GUI

2. Run the OS upgrade file from ssh directory /opt/yarnlab/yarnman

sudo ./scripts/upgrade-baseos18.sh yarnman-linux-upgrade18-bundle-<Ver>-master-<Build>.tar.gz.sig 

Note: this command may require -i at the end depending on source version. It would then be ./scripts/....tar.gz -i

Yarnman SSL Certificates

Configuring Intermediate Certificates

Typical format for standard SSL.

/opt/yarnlab/yarnman/config

ssl-cert.cert - Standard certificate sent to clients

ssl-key.pem - Private key file for checking response

In order to enable intermediate certificates we must create new folder in /config.

~/config
  /ca
    1-name.crt
    2-name.crt
    3-name.crt

The /ca folder contains the intermediate certificates that will be loaded in order. The easiest way to achieve this is to use the naming conventions 1-, 2- etc. Each certificate must end in .crt in order to be loaded.

Once the folder is created and at least one certificate is added in the format indicated the services on the node must be restarted.

Generate CSR

To acquire a new certificate you must generate a CSR (Certificate Signing Request). This may be done initially after creating private key or when a certificate expires
Certificate Locations /opt/yarnlab/yarnman/config
ssl-cert.cert - Standard certificate sent to clients
ssl-key.pem - Private key file for checking response
Open ssh session to server – go to /opt/yarnlab/yarnman/config

To generate CSR

...

[req]
distinguished_name  = req_distinguished_name
req_extensions = v3_req
[ req_distinguished_name ]
emailAddress      = Email Address (emailAddress_max    = 64)
[ v3_req ]
basicConstraints = CA:FALSE
keyUsage = nonRepudiation, digitalSignature, keyEncipherment
subjectAltName = @alt_names (Recommend using DNS name here)
[alt_names]
DNS.1 = <DNS name>

Backup and Restore

Backup Yarnman

Open SSH session

Run command: cd /opt/yarnlab/yarnman

Run the backup script:  ./scripts/backup-yarnman.sh -b

Backup script will create Backup Directory /opt/yarnlab/backup and create backup file

Restoring Backup

Open SSH session

Ensure that the backup directory /opt/yarnlab/backup exists with backup file

Run command: cd /opt/yarnlab/yarnman

Run the restore script:  ./scripts/backup-yarnman.sh -r

The backup script will identify the latest backup in the backup directory and restore from there
