Centos7 Redis集群部署

Redis安装参考:Redis主从配置并以普通用户启动

安装好以后以单机多实例的方式部署集群

1、创建配置和启动脚本

#cd /etc/redis

修改配置文件，开启集群模式

#vim 6379.conf

bind `192.168.2.90

appendonly yes

cluster-enabled yes

cluster-config-file nodes.conf

cluster-node-timeout 5000

#cp 6379.conf 7001.conf

#cp 6379.conf 7002.conf

#cp 6379.conf 7003.conf

#cp 6379.conf 7004.conf

#cp 6379.conf 7005.conf

#cp 6379.conf 7006.conf

#sed -i 's@6379@7001@g' 7001.conf

#sed -i 's@6379@7002@g' 7002.conf

#sed -i 's@6379@7003@g' 7003.conf

#sed -i 's@6379@7004@g' 7004.conf

#sed -i 's@6379@7005@g' 7005.conf

#sed -i 's@6379@7006@g' 7006.conf

#cd  /etc/init.d/

#cp 6379.conf redis_7001.conf

#cp 6379.conf redis_7002.conf

#cp 6379.conf redis_7003.conf

#cp 6379.conf redis_7004.conf

#cp 6379.conf redis_7005.conf

#cp 6379.conf redis_7006.conf

#sed -i 's@6379@7001@g' redis_7001.conf

#sed -i 's@6379@7002@g' redis_7002.conf

#sed -i 's@6379@7003@g' redis_7003.conf

#sed -i 's@6379@7004@g' redis_7004.conf

#sed -i 's@6379@7005@g' redis_7005.conf

#sed -i 's@6379@7006@g' redis_7006.conf

#mkdir /var/lib/redis/700{1..6}

# chown -R redis.redis /var/lib/redis/

2、启动实例

#/etc/init.d/redis_7001 start

#/etc/init.d/redis_7002 start

#/etc/init.d/redis_7003 start

#/etc/init.d/redis_7004 start

#/etc/init.d/redis_7005 start

#/etc/init.d/redis_7006 start

3、安装rvm

#gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3 7D2BAF1CF37B13E2069D6956105BD0E739499BDB

# \curl -sSL https://get.rvm.io | bash

#echo "source /etc/profile.d/rvm.sh" >> /root/.bashrc

#source /etc/profile.d/rvm.sh

4、安装ruby

#rvm list known #查看版本

#rvm install ruby-2.5.1

#gem -v  #安装好以后查看版本

5、更改gem源

#gem source -l    #查看镜像源

#gem source --remove https://rubygems.org/  #删除默认源

#gem source -a https://ruby.taobao.org  #新增gem的镜像源(确保只有ruby.taobao.org)

#gem sources -a https://mirrors.aliyun.com/rubygems/ #或者添加这个

6、安装redis-trib.rb

#gem install redis

#redis-trib.rb文件在解压包src目录下面

#redis-4.0.11/src/redis-trib.rb  create --replicas  1 192.168.2.90:7001 192.168.2.90:7002 192.168.2.90:7003 192.168.2.90:7004 192.168.2.90:7005 192.168.2.90:7006

Adding replica 192.168.2.90:7005 to 192.168.2.90:7001
