Install and configure Redis in Linux

Redis is a high-performance key-value database. The emergence of redis largely compensates for the shortage of keyvalue storage such as memcached, and can play a good complementary role in relational databases in some cases. It provides Python, Ruby, Erlang, and PHP clients for ease of use. The installation and testing steps are as follows:

1. Install redis:

[root@localhost ~]# cd /usr/local/src/[root@localhost src]# wget http://redis.googlecode.com/files/redis-2.2.12.tar.gz[root@localhost src]# tar zxf redis-2.2.12.tar.gz[root@localhost src]# cd redis-2.2.12[root@localhost redis-2.2.12]# make PREFIX=/usr/local/redis install

2. Configure redis:

[Root @ localhost redis-2.2.12] # mkdir-p/usr/local/redis/etc [root @ localhost redis-2.2.12] # mkdir-p/usr/local/redis/var [root @ localhost redis-2.2.12] # cd/usr/local/redis/etc [root @ localhost etc] # vi redis. conf (re-create the conf file and copy the following configuration)

3. Start and close redis:

[root@localhost ~]# /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf[root@localhost ~]# ps -ef|grep redisroot 3891 1 0 18:11 ?  00:00:00 /usr/local/redis/bin/redis-server /usr/local/redis/etc/redis.conf[root@localhost redis-2.2.12]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 shutdown

If you use the default ports 127.0.0.1 and 6379, You can omit the preceding parameters when executing the command.

4. Test redis:

[root@localhost ~]# telnet 127.0.0.1 6379Trying 127.0.0.1...Connected to localhost (127.0.0.1).Escape character is '^]'.^]telnet> quitConnection closed.

5. Description of the file execution function in the/usr/local/redis/bin directory:

Redis-server: daemon Startup Program of the Redis server

Redis-cli: Redis command line operation tool. Of course, you can also use telnet to operate based on its plain text protocol.

Redis-benchmark: Redis performance testing tool to test the read/write performance of Redis in your system and your configuration

-------------------------- Satisfied split line -----------------------------------

Instance:

1) log on and enter the following data:

[root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379redis 127.0.0.1:6379> set name csdnOKredis 127.0.0.1:6379> get name"csdn"redis 127.0.0.1:6379> quit

2) view redis statistics:

[root@localhost ~]# /usr/local/redis/bin/redis-cli -h 127.0.0.1 -p 6379 info

3) test performance:

Send 10 requests to the redis server, each with 50 concurrent clients,-n and-c

[root@localhost ~]# /usr/local/redis/bin/redis-benchmark -h 127.0.0.1 -p 6379 -n 10 -c 50
