Redis installation and client connection implementation (non-cluster environment construction)

1. Introduction to redis:

The advantages of redis as a cache:
1. Memory-level cache, the query speed is beyond doubt.
2. High-performance KV storage system, supports String, Hash, List, Set, Sorted Set and other data types, which can be applied in many scenarios.
3. Redis version 3.0 and above supports cluster deployment.
4. Redis supports data persistence, AOF, RDB methods.

Most of the time, we call redis an in-memory database, which stores key-value pair information in memory during operation, and writes it to the local database asynchronously in the background (default: dump.rdb, Configure in redis.conf. If you need to consider the security persistence requirements, you need to turn on the AOF function. For details, you can check this article: redis persistence), the key stored in redis can be of any type, and will eventually be stored as byte[] Type; there are many types of value: string, list, set, sortedset, hash, which can basically meet the key-value storage requirements in development; in addition, redis also supports transactions, message systems and other functions, and provides various client-side APIs such as Java, Python, Shell, etc.

2. To install redis on the Linux server,
    first attach the official website to download and install the basic tutorial: https://redis.io/download The
 
   first step is to download and decompress
   cd /root/redis/
   wget http://download.redis.io/releases/redis -3.2.8.tar.gz
   decompression
   tar xvzf redis-3.2.8.tar.gz -C /usr/local/src/ The
  
   second step is to compile and install
   make
   make all
   make install

   The third step
   to create a folder
   mkdir /root/redis/bin
   will be /root/redis/redis -3.2.8 Copy the executable file under the/src file to the created folder
redis-benchmark redis-check-aof redis-check-dump redis-cli redis-sentinel redis-server

cp /root/redis/redis-3.2. 8/sr-* /root/redis/bin

Copy the redis.conf of the decompressed file in the /root/redis/redis-3.2.8/src directory to /usr/redis
cp /usr/local/src/redis- 3.2.8/redis.conf /root/redis/bin

  Step 4 Install tlc
