Use Ruby's own tools for Redis cluster building

Use the source to install Redis and download the 3.0 version on the official website.

(1) Make sure the system is installed zlib, otherwise the gem install will report (no such file to load--zlib)

2. #download: zlib-1.2. 6. Tar

4. ./configure

6. Make

8. Make install

(2) Installing Ruby

2. # ruby1. 9.2

4. Cd/home/searat/ruby

6. ./configure-prefix=/usr/local/ruby

8. Make

10. Make install

12. CP Ruby/usr/local/bin

(3) Installation Rubygem

2. # rubygems-1.8. tgz.

4. CD /home/searat/gem

6. Ruby Setup.rb

8. CP Bin/gem/usr/local/bin

(4) Installation Gem-redis

1. Gem Install Redis--version 3.0. 0

   
   

wget http://rubygems.org/gems/redis/versions/3.0.0   

1. Gem install-l/home/searat/redis-3.0. 0. Gem

Processing of the Redis directory is then done

Use the source code after the installation directory as follows:

-bash-4.1$ tree-l 2/Home/searat/redis

/Home/searat/redis

├──bin

│├──dump.rdb

│├──redis-benchmark

│├──redis-check-aof

│├──redis-check-dump

│├──redis-cli

│├──redis-sentinel-Redis-server

│└──redis-server

├──conf

│├──dump.rdb

│└──redis.conf

├──log

│└──redis.log

└──redis_6379

Copy the REDIS-TRIB.RB to/Home/searat/redis/bin from the source package, and find the Create-cluster script from the source package, copy to/Home/searat/redis Under the/bin.

If you are using Create-cluster to create a Redis cluster on a single server, execute the create-cluster script directly.

If you create a Redis cluster on two or more servers, you can overwrite the Create-cluster script

-bash-4.1$ cat create-cluster #!/bin/bashport=$2    #端口号可以自己随意指定PORTNUM =3 # Define the number of port numbers replicas=1redis_home=/home/searat/redishost1=192.168.1.101host2=192.168.1.102hosts= "$HOST 1  $HOST 2 The declare -a hostgroup   #定义一个数组用来存放IP:P data in ORT form, using i=1if [  "$"  == when creating a cluster   "Start"  ]then    while [  $PORTNUM  -gt  "0"  ]; do         echo  "starting 127.0.0.1: $PORT"           $REDIS _home/bin/redis-server&nbsp ... /conf/redis_$port.confport=$ ((port+1)) portnum=$ ((PORTNUM-1))     done     exit 0fiif [  "$"  ==  "Stop"  ]then    while [   $PORTNUM  -gt  "0"  ]; do        echo  " stopping 127.0.0.1: $PORT "         $REDIS _home/bin/redis-cli -p  $PORT  shutdown nosave         port=$ ((port+1))         portnum=$ ((PORTNUM-1))      done    exit 0fiif [  "$"  ==  "create"  ]then     while [  $PORTNUM  -gt  "0"  ]; do         for host in  $HOSTS              do                 hostgroup[$i]= $host: $PORT                  i= ' expr  $i  + 1 '              done        port=$ ((PORT+1))          portnum=$ ((PORTNUM-1))     done    echo ${HOSTGROUP[*]}      $REDIS _home/bin/redis-trib.rb create --replicas 1 ${hostgroup[*]}     exit 0fiif [  "$"  ==  "clean"  ]then    rm - RF&NBSP, .... /LOG/*.LOG    RM -RF&NBSP, .... /DATA/APPENDONLY*.AOF    RM -RF&NBSP, .... /DATA/DUMP*.RDB    RM -RF&NBSP, .... /data/nodes*.conf    exit 0fiecho  "Usage: $0 [start|create|stop|clean" echo  "start       -- launch redis cluster  Instances.

As for redis_6379.conf, redis_6380.conf These configuration files can be configured in advance, or you can continue to append the code to automatically generate the configuration file in Create-cluster.

Redis Cluster Start-stop:/home/searat/redis/bin/create-cluster start/stop 6379

Create a cluster:/home/searat/redis/bin/create-cluster create 6379

If the following information is prompted, the creation is successful:

[OK] All nodes agree about Slotsconfiguration.

>>>check for open Slots ...

>>>check Slots Coverage ...

[OK] All 16384 slots covered.

Verify the master, slave information:

yes! In this way, the Redis cluster is created by Create-cluster, which is convenient for management and easy to expand.
