Centos7 install rediscluster in vmware

Centos7 install rediscluster in vmware

System Environment: Centos7 vmware
Redis version: redis3.2.5
Redis3.2.5 requires a later version of ruby and gem. The latest version 2.3.3 is used for ruby on our side. errors may occur when a later version of ruby creates a cluster.
Installation steps:

I. Initialization of required tools

1. Install the SDK

#yum install openssl* openssl-devel zlib-devel gcc gcc-c++ make autoconf readline-devel curl-devel expat-devel gettext-devel

Openssl, zlib, and gcc are required when installing ruby and gem.2. Install ruby

# wget https://cache.ruby-lang.org/pub/ruby/2.3/ruby-2.3.3.tar.gz# tar zxvf ruby-2.0.0-p247.tar.gz# cd ruby-2.0.0-p247# ./configure # make && make install# ruby -v 

3. Install redis-gem

# wget https://rubygems.global.ssl.fastly.net/gems/redis-3.2.1.gem# gem install redis-3.2.1.gem 

Ii. rediscluster Construction1. Download and install redis

# wget http://download.redis.io/releases/redis-3.2.5.tar.gz # tar -zxf redis-3.2.5.tar.gz# cd redis-3.2.5# make && make install

2. Create six redis. conf files for cluster configuration (the cluster requires at least 6 nodes)

# Mkdir conf # cd conf # vi redis-6379.conf # cp redis-6379.conf redis-6380.conf # cp redis-6379.conf # cp redis-6381.conf redis-6379.conf # cp redis-6382.conf redis-6379.conf # cp redis-6383.conf redis-6379.conf 6379 daemonize yesdir/data/redis/redis-6384.confport/data /redis/redis-7000/redis-6379.logpidfile/var/run/redis-6379.pid dbfilename dump-6379.rdb appendonly yes appendfilename "appendonly-6379.aof" cluster-enabled yes cluster-config-file nodes-6379.conf cluster-node-timeout 5000 protected-mode no # disable protection mode

Note: For more information about the protected-mode function, see the following link.

3. Start the service

# ./src/redis-server conf/redis-6379.conf# ./src/redis-server conf/redis-6380.conf# ./src/redis-server conf/redis-6381.conf# ./src/redis-server conf/redis-6382.conf# ./src/redis-server conf/redis-6383.conf# ./src/redis-server conf/redis-6384.conf

4. Create a cluster using the second IP address. The jediscluster created with 127.0.0.1 cannot be connected.-replicas 1 indicates that each master has one slave.

# ./src/redis-trib.rb create --replicas 1 127.0.0.1:6379 127.0.0.1:6380 127.0.0.1:6381 127.0.0.1:6382 127.0.0.1:6383 127.0.0.1:6384# ./src/redis-trib.rb create --replicas 1 172.21.20.25:6379 172.21.20.25:6380 172.21.20.25:6381 172.21.20.25:6382 172.21.20.25:6383 172.21.20.25:6384

5. Cluster Detection

#redis-cli -h 172.21.20.25 -p 6379

3. jediscluster used by the client to connect to the client, springboot 1 and maven jar

<dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version><!--$NO-MVN-MAN-VER$--></dependency>

4. Firewall Shutdown

My virtual machine is the default firewall of centos7, and iptables is used by default under 7.

Systemctl stop firewalld. service # disable firewall systemctl stop firewalld. service # stop firewallsystemctl disable firewalld. service # disable firewall startup

The iptables setting method takes effect permanently after restart: Enable: chkconfig iptables on Disable: chkconfig iptables off takes effect immediately, and expires after restart: Enable: service iptables start

Close: service iptables stop restart: service iptables restart save configuration: service iptables save or/etc/rc. d/init. d/iptables save to set the firewall to start systemctl enable iptables when it is started. disable/sbin/chkconfig-level 2345 iptables off when the firewall is started.
