Redis installation in Linux

Redis is one of the most popular NoSQL systems 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.

Latest Version: 2.8.3

It is very easy to install Redis under Linux, as described in the following steps (official website):

1, download the source code, unzip and compile the source code.

$ wget http://download.redis.io/releases/redis-2.8.3.tar.gz$ tar xzf redis-2.8.  3. tar.gz$ CD redis-2.8.  3$ make

If you execute make command error: Error:jemalloc/jemalloc.h:no such file or directory, this is due to the allocator allocator, if there is malloc this environment variable, will be useful for this environment variable to build R Edis

And libc is not the default allocator, the default is Jemalloc, because Jemalloc is proven to have fewer fragmentation problems than libc.

But if you don't have a jemalloc and only libc of course make a mistake. So executing make requires a parameter: Make MALLOC=LIBC

2, after the completion of the compilation, in the SRC directory, there are four executable files Redis-server, Redis-benchmark, Redis-cli and redis.conf. And then copy it to a directory.

mkdir/usr/rediscp redis-server  /usr/rediscp redis-benchmark/usr/rediscp redis-cli  /usr/  REDISCP redis.conf  /usr/rediscd/usr/redis    

3. Start Redis service.

$ redis-server   redis.conf

4, then use the client to test whether to start successfully.

$ redis-setget foo"bar"
