Configure the database management system installed:

  1. Enable connection to the Valkey server. To do it, edit the /etc/Valkey/Valkey.conf configuration file by adding the IP address of the server, e. g. 192.168.10.10:

sudo nano /etc/valkey/valkey.conf
bind 127.0.0.1 ::1 192.168.10.10

Enable TLS/SSL in Valkey

 
To enable TLS/SSL in Valkey, in the valkey.conf configuration file:

  1. Disable unprotected connections by setting the port parameter to 0. 
  2. Set the port for TLS connections and uncomment the tls-port parameter.
  3. In the tls-cert-file parameter, specify the path to the server certificate file.
  4. In the tls-key-file parameter, specify the path to the private key file.
  5. In the tls-ca-cert-file parameter, specify the path to the root CA file.

port 0
tls-port 6379
tls-cert-file /path/Valkey.crt
tls-key-file /path/Valkey.key
tls-ca-cert-file /path/to/ca.crt

 
Learn more about TLS/SSL in Valkey in the official Valkey documentation.
  1. Increase the maximum number of clients by setting the maxclients parameter to 20000. Uncomment the line by removing the # sign:

maxclients 20000

  1. Set the key eviction policy by setting the maxmemory-policy parameter to allkeys-lfu. Uncomment the line by removing the # sign:

maxmemory-policy allkeys-lfu

  1. Disable creation of snapshots by setting the save parameter to null. Uncomment the line by removing the # sign:

save ""

  1. Disable the AOF (Append Only File) to prevent saving of Valkey data in a file. To do it, set the appendonly parameter to no. Uncomment the line by removing the # sign:

appendonly no

  1. Disable the protected mode if the bind 0.0.0.0 parameter is used or the requirepass option is not set:

protected-mode no

  1. Restart Valkey:

sudo systemctl restart valkey-server

Step 3: Connection to Valkey

Connection string for Valkey:

redis://<valkey-server-address>:6379/0

Connection string for Valkey with TLS/SSL:

rediss://<valkey-server-address>:6379/0
