[SPN9] REDIS password change

Scope :

This article describes the methodology in order to define a password to REDIS.

By default, there is no password defined.

 

Methodology :

Following components may connect to Redis:

• ses-console (for session cache)
• ses-gateway (for api session cache)
• PTE (for translation cache). Redis parameters are retrieved from TRM configuration.

The order of the password reconfiguration is as follows :

 

1. SES Console

Through WebUI, go to Administration / Settings. Then edit the Redis settings section by setting the Redis authentication password parameter with the requested Redis password.

 

Then restart the systran-ses-console service.

# systemctl restart systran-ses-console.service

 

 

2. SES Gateway

Edit the .yml config file within /opt/systran/apps-node/translation-gateway/config.

And set the Redis password in front of pass directive.

      ApiKeys:
        Cache:
          host: localhost
          port: 6379
          pass:
          prefix: keyserv
          validity: 600 #in seconds, 0 for infinite

Then restart the systran-ses-gateway service. 

# systemctl restart systran-ses-gateway.service

 

3. Translation Resource Monitor

The change must be performed on each TRM node. Edit the /opt/systran/translation-resource-monitor/etc/trm.cfg file.

Uncomment only the redis-password directive and set it the requested Redis password.

#redis config
#with-redis-cache = true
#redis-host = localhost
#redis-port = 6379
#redis-key-prefix = PTE_
#redis-password = SESpassword

 Then restart the systran-translation-resource-monitor service.  

# systemctl restart systran-translation-resource-monitor.service

 

4. Redis password

Edit file /etc/redis.conf, uncomment line starting with "requirepass" and update with password (password "systran" for used below for REDIS :

requirepass systran

Relaunch REDIS :  

# systemctl restart redis

 

Translation testing

Test the translation.

If there are issues, restart all of the SPNS9 services and retest.
