Back to Top about Redis

Redis is one of the NoSQL (no only SQL, non-relational) databases that NoSQL stores data in the form of Key-value. The current mainstream distributed cache technology has REDIS,MEMCACHED,SSDB,MONGODB and so on. Redis can be understood as a caching technique, because its data is cached from it, and it can be understood as a database, because Redis may periodically write data to disk or append operations to a log file. I am personally more inclined to understand the caching technology, because today's Internet application Business complex, high concurrency, big Data features, it is a variety of caching technology to introduce the ultimate goal.

The comparison between Redis and traditional relational data, the comparison of Redis with memcached, and the advantages and disadvantages of Redis are not introduced here, because each has its own advantages, and only a combination of specific business scenarios can profoundly understand the differences and advantages and disadvantages between them. The following begins the installation of Redis on Linux.

Compiling the source program

[Email protected] ftpuser]# tar zxvf redis-3.2.0.tar.gz

[Email protected] ftpuser]# CD redis-3.2.0

[[email protected] redis-3.2.0]# make

[[Email protected] redis-3.2.0]# CD src && make install

Create a directory to hold Redis commands and configuration files

[Email protected] redis-3.2.0]# mkdir-p/usr/local/redis/bin

[Email protected] redis-3.2.0]# mkdir-p/usr/local/redis/etc

Moving Files

[Email protected] redis-3.2.0]# MV Redis.conf/usr/local/redis/etc

[[Email protected] redis-3.2.0]# CD src

[Email protected] src]# mv mkreleasehdr.sh redis-benchmark redis-check-aof redis-check-rdb redis-cli redis-server Redis-sentinel Redis-trib.rb/usr/local/redis/bin

Start Redis Service

[Email protected] ~]#/usr/local/redis/bin/redis-server/usr/local/redis/etc/redis.conf

As above, the boot Redis service needs to specify the configuration file, the background to start the need to modify the redis.conf file, daemonize no---->daemonize yes. The Redis server default link port is 6379, and it is a good idea to bind IP to a native IP as well.

Verify that startup is successful

[Email protected] ~]# Ps-ef | grep Redis

#或者

[Email protected] ~]# NETSTAT-TUNPL | grep 6379

Client Connections

[Email protected] ~]#/usr/local/redis/bin/redis-cli-h 192.168.2.128-p 6379

192.168.2.128:6379> Info

# Server

redis_version:3.2.0

redis_git_sha1:00000000

...

Stop Redis Service

[Email protected] ~]#/USR/LOCAL/REDIS/BIN/REDIS-CLI shutdown

#或者

[Email protected] ~]# Pkill redis-server

The installation of Redis on Linux is complete, and next we will learn about the common commands and data structures of Redis.
