Building Redis clusters with VMware virtual machines (Twemproxy)

Building Redis clusters with VMware virtual machines (Twemproxy)

1. Introduction to the Environment

Virtual machine: Vmware®workstation 11.0.0 build-2305329

Operating system: Ubuntu 14.04 Server AMD64

Redis version: Redis Server 2.8.4 bits=64

2. Environment configuration

A) The cluster consists of 1 proxy hosts and 5 Redis servers, and after installing the virtual machine in the usual way, you can get redis-server directly through Apt-get.

sudo apt-get install Redis-server

b) Modify the system configuration file

sudo echo vm.overcommit_memory=1 >>/etc/sysctl.conf

Sysctl Vm.overcommit_memory=1

Or

echo Vm.overcommit_memory=1 >>/proc/sys/vm/overcommit_memory

c) Configuring the network environment

In order to build a test LAN, in the virtual machine network I choose only host mode, restart the virtual machine, in order to facilitate the management of my LAN IP settings, The address of the slave-1 IPv4 address setting 192.168.131.101,slave-2 is set to 192.168.131.102, and by analogy.

sudo ifconfig eth0 192.168.131.10nsudo ifconfig eth0 downsudo ifconfig eth0 up

d) Configure the listening IP address of the Redis server

To configure the slave1~slave-5, use the editor to open/etc/redis/redis.conf, find bind 127.0.0.1, add your LAN address, here are modified to bind 192.168.131.10n 127.0.0.1

sudo vim/etc/redis/redis.confsudo service redis-server restart

Test on one of the slave servers to see if you can ping other hosts, and test through REDIS-CLI to see if data can be written and read
