Install Redis in Ubuntu 12.10 (graphic explanation) + Jedis to connect to Redis

To ensure that the permissions are correct, use the root account to perform the following operations.

1. Obtain the redis source code

Wgethttp: // redis.googlecode.com/files/redis-2.2.13.tar.gz

2. decompress and Set permissions.

 

Copy the decompressed and configured redis directory to the user directory/home/grid (personal habits, do not have to imitate)

 

3. make & make install

First, execute:

Root @ slavenode1:/home/grid/redis # make

 

Then execute:

Root @ slavenode1:/home/grid/redis # sudo make install

 

4. Copy key files to the target directory

Root @ slavenode1:/home/grid/redis # cp redis. conf/etc/
Root @ slavenode1:/home/grid/redis # cd src
Root @ slavenode1:/home/grid/redis/src # cp redis-benchmark redis-cli redis-server/usr/bin/
Root @ slavenode1:/home/grid/redis/src #

5. Start and verify the service

 

After starting redis, a warning message is reported.

Vm. overcommit_memory = 1

Append

/Etc/sysctl. conf

At the end of the file and execute

Sysctl vm. overcommit_memory = 1

Command

 

Restart redis without warning. Everything is OK:

 

Verify the startup status. Everything is normal:

 

6. Simple telnet Test

Note: a new window is required. The server window is running redis-server.

 

As shown in, when you connect to redis via telnet, the server window displays the following information:

[3523] 21 Jan 23:33:50-Accepted 127.0.0.1: 42711

 

Run the following simple command to perform the test (Note: The set command format here is set key value, which is slightly different from that demonstrated by the teacher. The reason is unknown ...):

Set/get setex

 

Lpush rpush lrange

 

 

7. Disable the service

Use commandsRedis-clishutdownYou can disable the redis server service.
