Installing a Redis cluster

installing a redis cluster

First step: Install dependent packages

1): Install Redis-cluster dependency: Redis-cluster dependent Library when using a compatibility problem, in Reshard encountered a variety of errors, please install according to the specified version.

(1) Ensure that the system is installed zlib, otherwise Geminstall will report (no such file to load-zlib) #download: Zlib-1.2.6.tar./configure making Make Inst All or yum install Zlib

(1) Install Ruby

Cd/path/ruby./configure-prefix=/usr/local/ruby make do install sudo cp ruby/usr/local/bin or yum install Rub Y

(2) installation

Rubygem:version (1.8.16)

#rubygems -1.8.16.tgz cd/path/gem sudo ruby setup.rb sudo cp bin/gem/usr/local/bin or yum install Rubygem

(3) Installing gem-redis:version (3.0.0)

Geminstall Redis--version 3.0.0 #由于源的原因, may download failed, download it manually down install #download地址: http://rubygems.org/gems/redis/versions/3.0. 0 Geminstall-l/data/soft/redis-3.0.0.gem

Step Two: Install redis-3.2.0

Tar XF redis-3.2.0.tar.gzcd redis-3.2.0makemake install CD SRC/CP redis-server/usr/local/bin CP redis-cli/usr/local/bi NCP Redis-trib.rb/usr/local/bin

Create the directory required by the cluster

[[email protected]/]mkdir-p/redis/{6000..6005}[[email protected]/] #cd/redis/[[email protected] redis]# lltotal 28DRW Xr-xr-x. 2 root root 4096 May 9 03:39 6000drwxr-xr-x. 2 root root 4096 May 9 03:54 6001drwxr-xr-x. 2 root root 4096 May 9 03:39 6002drwxr-xr-x. 2 root root 4096 May 9 03:39 6003drwxr-xr-x. 2 root root 4096 May 9 03:51 6004drwxr-xr-x. 2 root root 4096 May 9 03:39 6005[[email protected] redis]#

Modifying a configuration file redis.conf

Cp/home/lvnian/tools/redis-3.2.0/redis.conf/redisvi/redis/redis.conf

# #修改配置文件中的下面选项

Port 6000daemonize yescluster-enabled yescluster-config-file nodes.confcluster-node-timeout 5000appendonly Yes

# #修改完redis These configuration entries in the. conf configuration file, copy the configuration file to the 6000/6001/6002/6003/6004/6005 directory, respectively.

Cp/redis/redis.conf/redis/6000/cp/redis/redis.conf/redis/6001/cp/redis/redis.conf/redis/6002/cp/redis/redis.c onf/redis/6003/cp/redis/redis.conf/redis/6004/cp/redis/redis.conf/redis/6005/

# #注意: To modify the port parameter in the redis.conf file under the 6000/6001/6002/6003/6004/6005 directory after the copy is complete, change the name of the corresponding folder

Start each instance of Redis

1 Create cluster command to perform Redis create cluster

CD/HOME/LVNIAN/TOOLS/REDIS-3.2.0/SRC./REDIS-TRIB.RB Create--replicas 1 127.0.0.1:6000 127.0.0.1:6001 127.0.0.1:6002 127.0.0.1:6003 127.0.0.1:6004 127.0.0.1:6005

2 error occurs when executing the above command, because it is the Ruby script that is executed and requires the environment of Ruby

Error content:

/usr/bin/env:ruby:no such file or directory

so you need to install Ruby 's environment, it is recommended to use yum install ruby installation

Yum Install Ruby

3 then perform step 1 to create the cluster command, also error, hint missing rubygems component, use yum to install

Error content:

./redis-trib.rb:24:in ' require ': No such file to load – RubyGems (Loaderror) from./redis-trib.rb:24yum Install RubyGems

4 Repeat step 1 command, also error, indicating that Rediscannot be loadedbecause of the lack of Redis and Ruby interface, using gem to install

Error content:

/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in ' Gem_original_require ': No such file to load--Redis ( Loaderror) From/usr/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in ' require ' from./redis-trib.rb:25gem Install Redis

5. Repeat Step 1 of the order, normal execution

This is where the Redis cluster is built successfully!

Use redis-cli command into the cluster environment
