How to log in remotely with redis

There are two ways to log in to Redis remotely: forwarding through SSH port: After creating an SSH channel locally, connect to the local port to log in. Use Redis Sentinel: Install Redis Sentinel, configure configuration files, start Sentinel, and connect to the Redis master node after accessing the management interface.

How to remotely log in to Redis?

There are two main ways to log in to Redis remotely:

1. Forwarding via SSH port
2. Using Redis Sentinel

Method 1: SSH port forwarding

step:

1. Create an SSH channel on the local computer:

    <code>ssh -L [local_port]:127.0.0.1:[remote_port] [username]@[remote_host]</code>

   For example: ssh -L 6379:127.0.0.1:6379 user@remote-server

2. Connect to the local port:
   Connect to the local port using the Redis client (6379 in this example):

    <code>redis-cli -h localhost -p 6379</code>

Method 2: Redis Sentinel

Redis Sentinel is a tool for monitoring and managing Redis instances. It can provide Redis's failover and automatic failback capabilities.

step:

1. Install Redis Sentinel:

    <code>yum install redis-sentinel</code>

2. Configure Sentinel:
   Create the configuration file /etc/redis/sentinel.conf and specify the information for the Redis master and slave node.

3. Start Sentinel:

    <code>redis-sentinel /etc/redis/sentinel.conf</code>

4. Connect to the Sentinel management interface:
   Use a browser to access the Sentinel management interface:

    <code>http://[sentinel_host]:26379</code>

5. In the management interface, select the Redis master node to connect to.

Kind tips:

• The remote port (remote_port) should be the port that the Redis service is listening on.
• Make sure Redis service is enabled on the remote server and there is no firewall to block the connection.
• Sentinel is only available for Redis 2.8.12 or later.
