Ubuntu 16.04安装 redis 4.0.9

以三台服务器为例192.168.100.17 192.168.100.18 192.168.100.19

1、下载redis4.0.9 安装在每台服务器上

    cd /opt
    wget   http://download.redis.io/releases/redis-4.0.9.tar.gz
    tar  -zxvf  redis-4.0.9.tar.gz
   cd redis-4.0.9
   make & make install

2、创建目录

#在192.168.100.17创建目录
mkdir -p /opt/redis-4.0.9/redis-cluster/nodes-7000 /opt/redis-4.0.9/redis-cluster/nodes-7001

vim  /opt/redis-4.0.9/redis-cluster/nodes-7000/redis.conf

------------------------------------------------

port 7000  #节点端口,在不同的服务器和nodes-xx中
bind 192.168.100.17 #绑定ip
daemonize yes #后台运行
pidfile /var/run/redis_7000.pid #运行pid
dir /data/redis_data/7000 #数据存储地址
cluster-enabled yes
cluster-config-file nodes-7000.conf
cluster-node-timeout 5000
appendonly yes

-------------------------------------------------

mkmdir -p /data/redis_data/7000 /data/redis_data/7001
chmod -R 777 /data/redis_data


#在192.168.100.18创建目录
mkdir -p /opt/redis-4.0.9/redis-cluster/nodes-7002   /opt/redis-4.0.9/redis-cluster/nodes-7003



#在192.168.100.19创建目录
mkdir -p /opt/redis-4.0.9/redis-cluster/nodes-7004   /opt/redis-4.0.9/redis-cluster/nodes-7005

这边只举例17这台服务器,其对应的做修改，192.168.18新建nodes-7002、nodes-7003，192.168.100.19新建nodes-7004、nodes-7005

3、ruby安装

redis集群依赖ruby运行

apt install ruby
ruby -v 
gem install redis # 安装与redis相关的包


cp /usr/local/src/redis-4.0.1/src/redis-trib.rb  /usr/bin/ # 拷贝可执行文件（命令）,先看一下是否可以用这个命令,不是必须步骤

4、启动各个节点

#192.168.100.17
nohup src/redis-server redis-cluster/nodes-7000/redis.conf > redis-cluster/nodes-7000/redis-server.out 2>&1 &
nohup src/redis-server redis-cluster/nodes-7001/redis.conf > redis-cluster/nodes-7001/redis-server.out 2>&1 &

#192.168.100.18
nohup src/redis-server redis-cluster/nodes-7002/redis.conf > redis-cluster/nodes-7002/redis-server.out 2>&1 &
nohup src/redis-server redis-cluster/nodes-7003/redis.conf > redis-cluster/nodes-7003/redis-server.out 2>&1 &


#192.168.100.19
nohup src/redis-server redis-cluster/nodes-7004/redis.conf > redis-cluster/nodes-7004/redis-server.out 2>&1 &
nohup src/redis-server redis-cluster/nodes-7005/redis.conf > redis-cluster/nodes-7005/redis-server.out 2>&1 &

5、创建replicas

src/redis-trib.rb create --replicas 1 192.168.100.17:7000 192.168.100.17:7001 192.168.100.18:7002 192.168.100.18:7003 192.168.100.19:7004 192.168.100.19:7005

----------------------------------------------------------------

Adding replica 192.168.100.18:7003 to 192.168.100.17:7000
Adding replica 192.168.100.19:7005 to 192.168.100.18:7002

----------------------------------------------------------------

6、登录验证


redis-cli -c -h 192.168.100.17  -p 7000  # 加上-c选项表示以集群的方式登录

--------------------------

192.168.100.17:7000 > cluster nodes #cluster nodes命令可以列出节点
                      cluster info  #cluster info命令可以查看集群信息

--------------------------

redis-trib.rb check 192.168.100.17:7000  # 检测集群状态
