Redis cluster configuration

1. Download the tar package

redis-3.2.8.tar.gz

2. decompress the package to the specified directory.

sudo tar -xzvf redis-3.2.8.tar.gz -C /soft

3. Install the GCC compiler

sudo yum install -y gcc

4. Compile and install redis

$> Su root $> Cd ~ /Redis-3.2.8 # specify the installation directory $> make prefix =/soft/redis-3.2.8 install

5. Set soft connections and configure Environment Variables

Cluster construction:

1. Create the conf directory under/soft/redis

// Create six directories in conf: 7000-70005
For (I = 7000; I <7006; I ++); Do mkdir $ I; done;

2. template configuration file, redis. conf

3. Move the configuration to directories.

for(( i=7000;i<7006 ;i++)) ;do cp ./redis.conf $i ;done;

4. Modify

for(( i=7000;i<7006 ;i++)) ;do sed -i s/7000/$i/g $i/redis.conf  ;done;

5. Install the gem and integrate the redis cluster into the cluster.

// Install gem
Sudo Yum install-y gem

// Delete the old gem
Sudo gem sources -- remove https://rubygems.org/

// Add a new gem Source
Sudo gem sources-A https://gems.ruby-china.com/

// Use gem to install redis 3.0.0
Sudo gem install redis -- version 3.0.0

6. Add the redis process on each host to the cluster tribe

// Only change the operation for the first time
/Home/centos/redis-3.2.8/src/redis-trib.rb create -- replicas 1 192.168.137.101: 7000 192.168.137.101: 7001 192.168.137.101: 7002 192.168.137.101: 7003 192.168.137.101: 7004 192.168.137.101: 7005

Yes

7. Start the client to connect to the Cluster

redis-cli -c -h 192.168.231.101 -p 70000

8. Test cluster redirection through key operations

 

Management Cluster:

1. Start the redis Cluster

for x in 0 1 2 3 4 5 ; do redis-server 700$x/redis.conf ;done

2. Kill the redis Process

$>su root$>netstat -anop |grep 700 |grep LIST | awk ‘{print $7}‘ | awk-F / ‘{print $1}‘ | kill -9 `xargs`

3. View All redis Processes

netstat -anop |grep 700 |grep LIST
