How to set redis access password under Linux
Today the server installed redis. For security, set the password to access redis-server.
Recommended: "redis tutorial"
1. Find the redis.conf file
Our server has installed redis, now check redis through the command Process:
[root@lnp ~]# ps -aux|grep redis root 7374 0.0 0.0 145312 7524 ? Ssl 16:37 0:00 redis-server 192.168.17.105:6379 root 10692 0.0 0.0 112724 984 pts/7 S+ 16:54 0:00 grep --color=auto redis
You can see that the service address of our redis-server is 192.168.17.105 and the port is 6379. When accessing externally, you need to specify the corresponding IP and port:
redis-cli -h 192.168.17.105 -p 6379
Search redis installation directory
> whereis redis redis: /usr/local/redis
We can see that redis is installed in this directory, and then find the configuration file redis.conf
> find /usr/local/redis/ -name redis.conf /usr/local/redis/etc/redis.conf
Modify the configuration file:
vim redis.conf
Change the configuration file That’s it:
# requirepass foobared requirepass 123 指定密码123
The last step is to reload the configuration file:
redis-server /usr/local/redis/etc/redis.conf
2. Connection test
Access via password -a:
> redis-cli -h 192.168.17.105 -p 6379 -a 123
Running result:
[root@lnp etc]# redis-cli Could not connect to Redis at 127.0.0.1:6379: Connection refused Could not connect to Redis at 127.0.0.1:6379: Connection refused not connected> exit [root@lnp etc]# redis-cli -h 192.168.17.105 -p 6379 192.168.17.105:6379> keys * (error) NOAUTH Authentication required. 192.168.17.105:6379> exit [root@lnp etc]# redis-cli -h 192.168.17.105 -p 6379 -a 123 Warning: Using a password with '-a' option on the command line interface may not be safe. 192.168.17.105:6379> keys * (empty list or set) 192.168.17.105:6379> exit

Redis cluster mode deploys Redis instances to multiple servers through sharding, improving scalability and availability. The construction steps are as follows: Create odd Redis instances with different ports; Create 3 sentinel instances, monitor Redis instances and failover; configure sentinel configuration files, add monitoring Redis instance information and failover settings; configure Redis instance configuration files, enable cluster mode and specify the cluster information file path; create nodes.conf file, containing information of each Redis instance; start the cluster, execute the create command to create a cluster and specify the number of replicas; log in to the cluster to execute the CLUSTER INFO command to verify the cluster status; make

Using the Redis directive requires the following steps: Open the Redis client. Enter the command (verb key value). Provides the required parameters (varies from instruction to instruction). Press Enter to execute the command. Redis returns a response indicating the result of the operation (usually OK or -ERR).

The steps to start a Redis server include: Install Redis according to the operating system. Start the Redis service via redis-server (Linux/macOS) or redis-server.exe (Windows). Use the redis-cli ping (Linux/macOS) or redis-cli.exe ping (Windows) command to check the service status. Use a Redis client, such as redis-cli, Python, or Node.js, to access the server.

Redis uses hash tables to store data and supports data structures such as strings, lists, hash tables, collections and ordered collections. Redis persists data through snapshots (RDB) and append write-only (AOF) mechanisms. Redis uses master-slave replication to improve data availability. Redis uses a single-threaded event loop to handle connections and commands to ensure data atomicity and consistency. Redis sets the expiration time for the key and uses the lazy delete mechanism to delete the expiration key.

How to clear Redis data: Use the FLUSHALL command to clear all key values. Use the FLUSHDB command to clear the key value of the currently selected database. Use SELECT to switch databases, and then use FLUSHDB to clear multiple databases. Use the DEL command to delete a specific key. Use the redis-cli tool to clear the data.

To read a queue from Redis, you need to get the queue name, read the elements using the LPOP command, and process the empty queue. The specific steps are as follows: Get the queue name: name it with the prefix of "queue:" such as "queue:my-queue". Use the LPOP command: Eject the element from the head of the queue and return its value, such as LPOP queue:my-queue. Processing empty queues: If the queue is empty, LPOP returns nil, and you can check whether the queue exists before reading the element.

The best way to understand Redis source code is to go step by step: get familiar with the basics of Redis. Select a specific module or function as the starting point. Start with the entry point of the module or function and view the code line by line. View the code through the function call chain. Be familiar with the underlying data structures used by Redis. Identify the algorithm used by Redis.

Using Redis to lock operations requires obtaining the lock through the SETNX command, and then using the EXPIRE command to set the expiration time. The specific steps are: (1) Use the SETNX command to try to set a key-value pair; (2) Use the EXPIRE command to set the expiration time for the lock; (3) Use the DEL command to delete the lock when the lock is no longer needed.
