How to build a redis environment, in view of this problem, this article introduces the corresponding analysis and answers in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

Because there is redis in the work environment, I learned about redis. Of course, the first step is to build the environment. Here is my record of building the redis environment.

The system is SuSE 11 sp2

The software environment is as follows:

Linux-svnfile:/home/apps/redis # ls

Redis-3.0.0.gem ruby-1.9.2-p290.tar.gz zlib-1.2.7.tar.gz

Redis-3.0.0.tar.gz rubygems-2.4.6.tgz

Redis.conf zlib-1.2.6.tar.gz

Install the base environment:

Linux-svnfile:/home/apps/redis # tar-zxf zlib-1.2.6.tar.gz-C / usr/local/src

Linux-svnfile:/usr/local/src/zlib-1.2.6 #. / configure-prefix=/usr/local/zlib

Linux-svnfile:/usr/local/src/zlib-1.2.6 # make & & make install

Linux-svnfile:/home/apps/redis # tar-zxf ruby-1.9.2-p290.tar.gz-C / usr/local/src

Linux-svnfile:/usr/local/src/ruby-1.9.2-p290 #. / configure-prefix=/usr/local/ruby

Linux-svnfile:/usr/local/src/ruby-1.9.2-p290 # make & & make install

Linux-svnfile:/usr/local/ruby # ln-s / usr/local/ruby/bin/ruby / usr/local/bin

Linux-svnfile:/home/apps/redis # tar xf rubygems-2.4.6.tgz-C / usr/local/src

Linux-svnfile:/usr/local/src # mv rubygems-2.4.6.. / gem

Linux-svnfile:/usr/local/gem # ruby setup.rb

Linux-svnfile:/usr/local/gem # cp bin/gem / usr/local/bin/

Linux-svnfile:/home/apps/redis # gem install-l redis-3.0.0.gem

Successfully installed redis-3.0.0

Installing ri documentation for redis-3.0.0

Done installing documentation for redis after 0 seconds

1 gem installed

Linux-svnfile:/home/apps/redis # tar-zxf redis-3.0.0.tar.gz-C / usr/local/src

Linux-svnfile:/usr/local/src # mv redis-3.0.0.. / redis

Linux-svnfile:/usr/local/redis # make

At this point, the basic environment has been built.

Let's build the cluster.

Linux-svnfile:/usr/local/redis # cp src/redis-server / usr/local/bin/

Linux-svnfile:/usr/local/redis # cp src/redis-cli / usr/local/bin/

Linux-svnfile:/usr/local/redis # cp src/redis-trib.rb / usr/local/bin

Linux-svnfile:/usr/local/redis # mkdir-p / usr/local/cluster/ {7000.7005}

Linux-svnfile:/usr/local/redis # vi redis.conf

Daemonize yes

Port 7000

Cluster-enabled yes

Cluster-config-file nodes.conf

Cluster-node-timeout 5000

Appendonly yes

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7000

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7001

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7002

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7003

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7004

Linux-svnfile:/usr/local/redis # cp redis.conf.. / cluster/7005

It should be noted here that the file name corresponds to the configuration of the port in the file. For example, the port parameter under file 7001 needs to be changed to 7001, and other changes should be made as well.

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7000/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7001/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7002/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7003/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7004/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7005/redis.conf

Linux-svnfile:/usr/local/redis # ps-ef | grep redis

For example, when starting the service above, you need to switch to the directory of the corresponding configuration file, otherwise the service of the corresponding port cannot be started. For example, only 7000 of the corresponding service has been started after I started it in the / usr/local/redis directory.

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7000/redis.conf

Linux-svnfile:/usr/local/redis # redis-server.. / cluster/7001/redis.conf

Delete a slave nod

Delete a master nod

Linux-svnfile:/usr/local/redis # redis-trib.rb reshard 127.0.0.1:7001

How many slots do you want to move (from 1 to 16384)? 5461

What is the receiving node ID? 42929649e533ec8aad7cbb81f204f04c849d4bff

Please enter all the source node IDs.

Type 'all' to use all the nodes as source nodes for the hash slots.

Type 'done' once you entered all the source nodes IDs.

Source node # 1: 6fe9561e605b7ee85e67a2557f7fb641f482afb4

Source node # 2:done

# Do you want to proceed with the proposed reshard plan (yes/no)? Yes

Description:

5461 indicates that you want to delete all the slot quantity of master

What is the receiving node ID refers to the node-id of node 7001 that migrates the slot of 7000

Source node # 1 refers to the node-id of the master to be deleted

Below, you can see that the slot of 7000 is 0, while 7001 is more than 4561.

The error shown below occurs when deleting the master node because the slave node of the master node was not deleted before deleting the master node.

The above is a cluster done on a single machine, and the following shows a cluster on two machines, which is actually very simple.

Refer to the previous environment to compile the source code to another machine

Edit the configuration file on both machines

/ usr/local/redis # vi redis.conf

Daemonize yes

Port 7000

Cluster-enabled yes

Cluster-config-file nodes.conf

Cluster-node-timeout 5000

Appendonly yes

Cluster-config-file nodes-7001.conf

Create directories and files respectively

Linux-svnfile:/usr/local/redis # mkdir-p/usr/local/cluster/ {7001.. 7003}

Localhost:/usr/local/redis # mkdir-p/usr/local/cluster/ {8001.. 8003}

Linux-svnfile:/usr/local/redis # cpredis.conf.. / cluster/7001

Linux-svnfile:/usr/local/redis # cpredis.conf.. / cluster/7002

Linux-svnfile:/usr/local/redis # cpredis.conf.. / cluster/7003

Localhost:/usr/local/redis # cp redis.conf../cluster/8001

Localhost:/usr/local/redis # cp redis.conf../cluster/8002

Localhost:/usr/local/redis # cp redis.conf../cluster/8003

Modify the configuration file of the corresponding directory where port and cluster-config-file correspond to their respective directory names respectively, which can be modified using the sed command

Sed-I "s Universe 7001max 7002Universe g"

Start the service
