Centos7.0 redis cluster installation

Centos7.0 redis cluster installation

1. Install [redis](/search?q=redis) (use redis3.2.1 version)

1. Install necessary packages

 
    yum install gcc

2. Download the redis3.2.1 installation package

 #redis installer download directory (to personal preference)
    
 cd /home/htld/tools
    
  
    
 #Execute downloads
    
 wget https://download.redis.io/releases/redis-3.2.1.tar.gz
    
  
    
    
    

3. Unzip the source code package

  #decompression
    
 tar -zxvf redis-3.2.1.tar.gz
    
  
    
    
    

4. Enter the decompression directory and compile

  #Go to the redis-3.2.1 directory.
    
 cd redis-3.2.1/ 
    
  
    
 #compiling
    
 make
    
    
    

After the make command is executed, this executable file will be generated in the src directory, which are redis-server, redis-cli, redis-benchmark, and redis-stat. Their functions are as follows:

• redis-server: Daemon startup program of Redis server
• redis-cli: Redis command line operation tool. Of course, you can also use telnet to operate according to its plain text protocol
• redis-benchmark: Redis performance testing tool, test the read and write performance of Redis under your system and your configuration
• redis-stat: Redis status detection tool, which can detect Redis current status parameters and delay conditions

5. Install redis

 
    make install PREFIX=/usr/local/redis

2. Start redis

1. Copy redis-conf from the redis-3.2.1 file to the redis installation directory

 
    cp /home/htld/tools/redis-3.2.1/redis.conf /usr/local/redis/
    

2. Then modify the redis.conf file

3. Start redis in the bin directory

 
    ./redis-server ../redis.conf

4. Kill all redis nodes

 
    pkill -9 redis

3. Construction of redis cluster

1. Install ruby ​​environment

1.1 Online installation

 
    yum install ruby
    

2. Download redis-3.2.1.gem

Install ruby ​​packages

 
    gem install redis-3.2.1.gem

3. Modify redis.conf

4. Copy the redis-trib.rb command in the redis-3.2.1 directory

 
    cp /home/htld/tools/redis-3.2.1/src/redis-trib.rb /usr/local/redis/bin/
    

5. In the same way, repeat the above steps on the other 5 servers.

6. After the redis installation and configuration of the 6 servers are successful, start the redis of the 6 servers separately.

   
    
 cd /usr/local/redis/bin/
    
 #priming command
    
 ./redis-server ../redis.conf
    
    
    

7. Randomly select a server and execute the create cluster command

 
    ./redis-trib.rb create --replicas 1 192.168.200.41:6379 192.168.200.42:6379 192.168.200.43:6379 192.168.200.44:6379 192.168.200.45:6379 192.168.200.46:6379

8. On another server, detect the cluster again (optional)

 
    ./redis-trib.rb check 192.168.200.43:6379
