Redis5单机

1、创建目录

新建目录：
mkdir -p /home/download/redis
cd /home/download/redis

2、下载源码并解压编译

  1. wget http://download.redis.io/releases/redis-5.0.12.tar.gz
  2. tar xvzf redis-5.0.12.tar.gz
  3. cd redis-5.0.12
  4. make
  5. make install PREFIX=/home/software/redis

3、配置

移动配置文件到安装目录下
　　mkdir /home/software/redis/conf
　　mv redis.conf /home/software/redis/conf
配置redis配置文件
　　vi /home/software/redis/conf/redis.conf
修改为后台启动：将daemonize no 改成daemonize yes
绑定IP地址：bind 192.168.8.88 127.0.0.1
将redis目录加到PATH路径
vi ~/.bash_profile
修改PATH，PATH=$PATH:$HOME/bin:/home/software/redis/bin
使配置生效
source ~/.bash_profile
检查redis版本
redis-cli -v
将redis加入到开机启动 (可以不执行)
　　vi /etc/rc.local
在里面添加一行
/home/software/redis/bin/redis-server /home/software/redis/conf/redis.conf
启动redis
　　redis-server /home/software/redis/conf/redis.conf
停止redis
　　pkill redis

Redis5集群

1、简要说明

2018年十月 Redis 发布了稳定版本的 5.0 版本，推出了各种新特性，其中一点是放弃 Ruby的集群方式，改为 使用 C语言编写的 redis-cli的方式，是集群的构建方式复杂度大大降低。关于集群的更新可以在 Redis5 的版本说明中看到，如下：

The cluster manager was ported from Ruby (redis-trib.rb) to C code inside redis-cli. check redis-cli --cluster help for more info.

可以查看Redis官网查看集群搭建方式，连接如下
https://redis.io/topics/cluster-tutorial
以下步骤是在一台 Linux 服务器上搭建有6个节点的 Redis集群。

2、创建集群步骤

1、创建目录

新建目录：
mkdir -p /home/download/redis
cd /home/download/redis

2、下载源码并解压编译

  1. wget http://download.redis.io/releases/redis-5.0.12.tar.gz
  2. tar xvzf redis-5.0.12.tar.gz
  3. cd redis-5.0.12
  4. make
  5. make install PREFIX=/home/software/redis

4、将redis目录加到PATH路径

vi ~/.bash_profile
修改PATH，PATH=$PATH:$HOME/bin:/home/software/redis/bin
使配置生效
source ~/.bash_profile
检查redis版本
redis-cli -v

3、创建6个Redis配置文件

  1. 6个配置文件不能在同一个目录，此处我们定义如下：
  1. /home/software/redis/cluster-conf/7001/redis.conf
  2. /home/software/redis/cluster-conf/7002/redis.conf
  3. /home/software/redis/cluster-conf/7003/redis.conf
  4. /home/software/redis/cluster-conf/7004/redis.conf
  5. /home/software/redis/cluster-conf/7005/redis.conf
  6. /home/software/redis/cluster-conf/7006/redis.conf

配置文件的内容为：

  1. # 端口
  2. port 7001
  3. # 启用集群模式
  4. cluster-enabled yes
  5. cluster-config-file nodes.conf
  6. # 超时时间
  7. cluster-node-timeout 5000
  8. appendonly yes
  9. # 后台运行
  10. daemonize yes
  11. # 非保护模式
  12. protected-mode no
  13. # 密码
  14. requirepass Red2020dis
  15. pidfile 7001.pid
  16. dbfilename 7001.rdb
  17. bind 192.168.8.88 127.0.0.1

其中 port 和 pidfile 需要随着 文件夹的不同调增。

4、启动节点(需要cd到目录下执行)

  1. cd /home/software/redis/cluster-conf/7001/
  2. redis-server redis.conf
  3. cd /home/software/redis/cluster-conf/7002/
  4. redis-server redis.conf
  5. cd /home/software/redis/cluster-conf/7003/
  6. redis-server redis.conf
  7. cd /home/software/redis/cluster-conf/7004/
  8. redis-server redis.conf
  9. cd /home/software/redis/cluster-conf/7005/
  10. redis-server redis.conf
  11. cd /home/software/redis/cluster-conf/7006/
  12. redis-server redis.conf

5、启动集群

  1. redis-cli --cluster create 192.168.8.88:7001 192.168.8.88:7002 192.168.8.88:7003 192.168.8.88:7004 192.168.8.88:7005 192.168.8.88:7006 --cluster-replicas 1

启动后，可看到成功信息，如下：

  1. >>> Performing hash slots allocation on 6 nodes...
  2. Master[0] -> Slots 0 - 5460
  3. Master[1] -> Slots 5461 - 10922
  4. Master[2] -> Slots 10923 - 16383
  5. Adding replica 192.168.8.88:7004 to 192.168.8.88:7001
  6. Adding replica 192.168.8.88:7005 to 192.168.8.88:7002
  7. Adding replica 192.168.8.88:7006 to 192.168.8.88:7003
  8. >>> Trying to optimize slaves allocation for anti-affinity

至此，Reids5 集群搭建完成。

3、集群其他操作

1、关闭集群

redis5 提供了关闭集群的工具，在如下目录：
/home/download/redis/redis-5.0.10/utils/create-cluster
打开此文件修改端口为我们自己的，如下所示：

  1. #!/bin/bash
  3. # Settings
  4. PORT=7000
  5. NODES=6
  6. TIMEOUT=2000
  7. REPLICAS=1

端口PROT设置为7000，NODES为6，工具会自动累加1 生成 7001-7006 六个节点 用于操作。
修改后，执行如下命令关闭集群：

  1. /home/download/redis/redis-5.0.12/utils/create-cluster/create-cluster stop

2、重新启动集群

  1. /home/software/redis/redis-5.0.12/utils/create-cluster/create-cluster start

3、使用脚本文件启动集群

  1. #!/bin/sh
  2. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7001/redis.conf
  3. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7002/redis.conf
  4. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7003/redis.conf
  5. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7004/redis.conf
  6. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7005/redis.conf
  7. /home/software/redis/redis-server  /home/software/redis/cluster-conf/7006/redis.conf
  8. /home/software/redis/redis-cli -a password --cluster create 192.168.8.88:7001 192.168.8.88:7002 192.168.8.88:7003 192.168.8.88:7004 192.168.8.88:7005 192.168.8.88:7006 --cluster-replicas 1
