redis-cluster installation and configuration

集群的配置：
tar xzvf redis-3.2.5.tar.gz -C /usr/local/software/


[root@localhost redis-3.2.5]# make
[root@localhost redis-3.2.5]# make install


[root@localhost redis-3.2.5]# echo "vm.overcommit_memory=1">>/etc/sysctl.conf

redis-6379.conf configuration file:

protected-mode no //Be sure to cancel the protected mode before configuration
port 6379 //Monitor port
daemonize yes //Background Run
pidfile /usr/local/software/data/redis/redis-6379/run/redis_6379.pid //Define pid save path
logfile "/usr/local/software/data/redis/redis-6379/logs/redis_6379.log " //Define log save path
dir /usr/local/software/data/redis/redis-6379/dbcache //Data save directory
(do not configure password # requirepass mldnjava comment out)
cluster-enabled yes //Open RedisCluster cluster
cluster-config-file nodes-6379.conf //Define the save file of the cluster configuration
cluster-node-timeout 15000 //Define the timeout time of the node (after this time, the node is considered to have died)




Copy the file: cp /usr/local/ software/redis/conf/redis-6379.conf /usr/local/software/redis/conf/redis-6380.conf

First make sure you have ruby ​​permissions on your host. Under
Ubuntu : apt-get install ruby ​​ruby-dev rubygems
Under CentOS: yum install ruby ​​ruby-dev rubygems


sudo yum install curl


yum update nss


gpg2 --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3


Install RVM
[ root@localhost /]# curl -L get.rvm.io | bash -s stable 
[root@localhost /]# source /usr/local/rvm/scripts/rvm
 View known ruby ​​versions in the rvm library
[root@localhost /]# rvm list known
Install a ruby ​​version
[root@localhost /]# rvm install 2.3.4
Using a ruby ​​version
[root@localhost /]# rvm use 2.3.4
Using /usr/local/rvm/gems/ruby-2.3.4
Uninstall a ruby-2.3.4 Known version
[root@localhost /]# rvm remove 2.0.0
ruby-2.0.0-p648 - #already gone
Using /usr/local/rvm/gems/ruby-2.3.4


First you need to compile redis:
[root @localhost /]# 
gem install redis
