Installation of Redis under Linux

Redis is one of the most popular NoSQL databases today, and it is a key-value storage system. Similar to memcached, but largely compensates for the lack of memcached, which supports storing more value types, including string, list, set, Zset, and hash. These data types support Push/pop, Add/remove, and intersection sets and differences, and richer operations. Based on this, Redis supports sorting in a variety of different ways. Redis data is cached in the computer's memory and periodically writes the updated data to disk or writes the modification to the appended record file.

Below we install Redis on CentOS

Download the source code, unzip and compile the source code.

[Email protected] temp]# wget http://download.redis.io/releases/redis-2.8.3.tar.gz[[Email Protected] temp]# tar zxvf redis-2.8.3. tar.gz [[email protected] temp]# CD Redis-2.8.3[email Protected] Redis-2.8.3] #make

Note that there is no make install

The installation directory is/usr/local/software/redis-2.8.3

1. View the files in the installation directory

2. After the compilation, in the SRC directory, there are several executable files Redis-server, Redis-benchmark, REDIS-CLI

The Daemon launcher for the Redis-server:redis server.
Redis-cli:redis command-line operation tool. Of course, you can also use Telnet to operate on its plain text protocol.
Redis-benchmark:redis Performance Testing tool to test the read and write performance of Redis in your system and in your configuration.

3. Start the Redis service.

1) execution./usr/redis/redis-2.8.13/src/redis-server

2) View process

[[Email protected] ~]# PS aux| grep redisroot       34597  0.0  0.7 137344  7640 pts/0    sl+  13:39   0:00./redis-server *:6379       Root       34608  0.0  0.0 103308   860 pts/1    s+   13:41   0:00 grep redis

3) then test with the client to see if it started successfully.

[[email protected] src]#./redis-127.0.0.1:6379> set greet Hellook127.0.0.1:6379> get Greet

Note that the Redis service cannot run in the background at this point, and CTRL + C ends the Redis service

Need to configure the Redis service to run in the background, it's a little cumbersome, we don't deserve it.
