Environmental Science

Operating system: CentOS 7.3
Redis version: Redis 3.2.8
Two hosts, three nodes on each host

Basic steps

Download and unzip the installation package

# Download and unzip the installation package
wget http://download.redis.io/releases/redis-3.2.8.tar.gz
tar -zxvf redis-3.2.8.tar.gz

Build install

# Normal compilation and installation
make && make install

# If gcc is not installed, install gcc
yum install gcc

# If the jemalloc memory allocator is not installed, compile the installation using the following command
make MALLOC=libc  && make install

Create corresponding directory and write configuration file

The following directory is used for this construction:

• Log directory / opt/redis/logs
• Data directory / opt/redis/db
• Cluster file directory: / opt / redis / cluster conf / port, such as: / opt / redis / cluster conf / 7001

Profile: Simple profile , pay attention to modify the IP and port of each node.

Start each node

# Start each node
cd /opt/redis/src
./redis-server ../cluster-conf/7001/redis.conf
./redis-server ../cluster-conf/7002/redis.conf
./redis-server ../cluster-conf/7003/redis.conf
./redis-server ../cluster-conf/7004/redis.conf
./redis-server ../cluster-conf/7005/redis.conf
./redis-server ../cluster-conf/7006/redis.conf

Create cluster

# Install ruby
yum -y install ruby ruby-devel rubygems rpm-build

# Install the redis package (specify the corresponding version number, https://rubygems.org/gems/redis)
gem install redis -v 3.3.0

# Create cluster
./redis-trib.rb create --replicas 1 192.168.192.128:7001 192.168.192.128:7002 192.168.192.128:7003 192.168.192.129:7004 192.168.192.129:7005 192.168.192.129:7006

• When using RubyGems to install Redis package, you need to indicate the version number, otherwise the latest version will be installed. Because the default version of Ruby for this version of CentOS is 2.0, the latest Redis package needs to be upgraded to the Ruby version before installation.
