How to install Redis on Centos7
Introduction
Redis is an open source (BSD licensed), in-memory data structure store used as a database, cache, and message broker. It supports data structures such as strings, hashes, lists, sets, sorted sets with range queries, bitmaps, hyperlogs, geospatial indexes with radius queries and streams. Redis has built-in replication, Lua scripts, LRU evictions, transactions and different levels of disk durability, and provides high availability through Redis Sentinel and automatic partitioning using Redis Cluster.
What is redis?
Memory-based key-value database supports automatic/manual persistence.
Performance:
The following is the official benchmark-mark data:
The test was completed with 50 concurrent executions of 100,000 requests.
The value set and obtained is a 256-byte string.
Result: The reading speed is 110000 times/s and the writing speed is 81000 times/s

Install
Install dependencies
yum install gcc-c -y
Create installation directory, compile and install
download link
wget http://download.redis.io/releases/redis-5.0.5.tar.gz
# -p Make sure the directory name exists, if not, create one
mkdir -p /home/software/redis
# -z: with gzip attribute, -x: decompression, -v: display all processes, -f: use the file name. Remember, this parameter is the last parameter, and can only be followed by the file name
tar zxvf redis-3.0.6.tar.gz
cd redis-3.0.6
# make is used for compilation. It reads instructions from the Makefile and then compiles
# make install is used for installation. It also reads instructions from the Makefile and installs it to the specified location. PREFIX selects the directory to be installed
make && make PREFIX=/home/software/redis install
Copy the configuration file and start
cd redis-5.0.5/
cp redis.conf /home/software/redis/bin
Modify /usr/local/redis/bin/redis.conf (the following modifications are based on redis5.0.5, other versions of redis may have differences)
Use the vim editor and enter: set number to display the number of lines (provided you have vim installed)
# Whether to serve as a daemon thread, Redis will write the pid file in /var/run/ Redis. When monitoring pid
At line 136
daemonize yes
If you need to modify the number of instances
At line 186
databases 32
Comment binding ip, you can connect to redis with ip
#bind 127.0.0.1
Add access password
At line 507
requirepass redis
start up
Switch to the bin directory under the installation directory
Execute the command. This configuration file is the one we just copied from the decompression directory
./redis-server redis.conf
Check the process
ps -ef | grep redis
Test connection

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

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.

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).

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.

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.

On CentOS systems, you can limit the execution time of Lua scripts by modifying Redis configuration files or using Redis commands to prevent malicious scripts from consuming too much resources. Method 1: Modify the Redis configuration file and locate the Redis configuration file: The Redis configuration file is usually located in /etc/redis/redis.conf. Edit configuration file: Open the configuration file using a text editor (such as vi or nano): sudovi/etc/redis/redis.conf Set the Lua script execution time limit: Add or modify the following lines in the configuration file to set the maximum execution time of the Lua script (unit: milliseconds)

Use the Redis command line tool (redis-cli) to manage and operate Redis through the following steps: Connect to the server, specify the address and port. Send commands to the server using the command name and parameters. Use the HELP command to view help information for a specific command. Use the QUIT command to exit the command line tool.
