腾讯云~Redis 伪分布式集群搭建2022版本+密码（linux环境）

Linux环境 安装 Redis-6.2.6 配置运行_01
https://gblfy.blog.csdn.net/article/details/105583077

一、节点分布总览

演示案例
3主3从 横向扩展

二、软件配置初始化

2.1~2.5属于公共部分，101/102/103服务器需要依次执行

2.1. 下载

wget https://download.redis.io/releases/redis-6.2.6.tar.gz
1

2.2. 解压

cd /app
tar -zxvf redis-6.2.6.tar.gz
1
2

2.3. 编译安装

cd redis-6.2.6/
make install
1
2

三、配置管理

3.1. 配置抽离

mkdir /app/redis-cluster/
cp /app/redis-6.2.6/redis.conf /app/redis-cluster/
1
2

3.2. 配置编辑

vim /app/redis-cluster/redis.conf
1

直接复制即可

# 绑定访问ip信息
bind 0.0.0.0

# # 修改对应的端口
port 7001

#修改为后台启动
daemonize yes

#关闭保护模式
protected-mode no

#启动AOF文件
appendonly yes

#指定数据文件存放位置，必须要指定不同的目录位置，不然会丢失数据
dir /usr/local/redis-cluster/redis-7001

# 日志文件名
logfile "redis-7001.log"

# .pid文件初始化
pidfile /var/run/redis_7001.pid

# 启动集群模式
cluster-enabled yes

# 节点离线的超时时间
cluster-node-timeout 15000
  
# 注释打开并修改node节点 
cluster-config-file nodes-7001.conf

#如果要设置密码需要增加如下配置：
#设置redis访问密码
requirepass pwd@2022gblfy

#设置集群节点间访问密码，跟上面一致
masterauth pwd@2022gblfy

按y依次替换

3.5. redis-7003.conf

 vim /app/redis-cluster/redis-7003.conf
1

将7001替换为7003

:%s/7001/7003/cg

按y依次替换

3.6. redis-7004.conf

 vim /app/redis-cluster/redis-7004.conf
1

将7001替换为7004

:%s/7001/7004/cg

按y依次替换

3.7. redis-7005.conf

 vim /app/redis-cluster/redis-7005.conf
1

将7001替换为7005

 :%s/7001/7005/cg

按y依次替换

3.8. redis-7006.conf

 vim /app/redis-cluster/redis-7006.conf
1

将7001替换为7006

 :%s/7001/7006/cg
1

按y依次替换

3.9. 创建目录

mkdir /usr/local/redis-cluster/redis-7001 -p
mkdir /usr/local/redis-cluster/redis-7002 -p
mkdir /usr/local/redis-cluster/redis-7003 -p
mkdir /usr/local/redis-cluster/redis-7004 -p
mkdir /usr/local/redis-cluster/redis-7005 -p
mkdir /usr/local/redis-cluster/redis-7006 -p

3.10. 启动redis

/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-7001.conf
/app/redis-6.2.6/src/redis-server /app/redis-cluster/redis-7002.conf

3.11. 监控redis状态

ps -ef|grep redis

四、集群搭建

上面仅仅是搭建了集群，6个节点之间还没有关系，下面通过 节点握手让集群各节点之间，发生关系。

4.1. 防火墙策略

centos7.x

firewall-cmd --zone=public --add-port=7001/tcp --permanent
firewall-cmd --zone=public --add-port=7002/tcp --permanent
firewall-cmd --zone=public --add-port=7003/tcp --permanent
firewall-cmd --zone=public --add-port=7004/tcp --permanent
firewall-cmd --zone=public --add-port=7005/tcp --permanent
firewall-cmd --zone=public --add-port=7006/tcp --permanent
firewall-cmd --zone=public --add-port=17001/tcp --permanent
firewall-cmd --zone=public --add-port=17002/tcp --permanent
firewall-cmd --zone=public --add-port=17003/tcp --permanent
firewall-cmd --zone=public --add-port=17004/tcp --permanent
firewall-cmd --zone=public --add-port=17005/tcp --permanent
firewall-cmd --zone=public --add-port=17006/tcp --permanent
firewall-cmd --reload

4.2.集群搭建

• -a pwd@2022gblfy 我们之前设置的密码
• –cluster-replicas 1 主从搭配比例，1表示一主一从，2表示一主2从，要使用可以被客户端访问到的ip
  登录腾讯云服务器的7001节点以下命令（默认按照顺序自动分配主从，一般顺序是一主一从按照你的命令排列顺序）：

redis-cli -a pwd@2022gblfy --cluster create --cluster-replicas 1 192.168.0.80:7001 192.168.0.80:7004 192.168.0.80:7003 192.168.0.80:7006 192.168.0.80:7005 192.168.0.80:7002 
1

执行完后会出现下面的界面，输入yes回车即可，我们可以得到以下信息，每一个主服务的哈希槽是多少
谁是主谁是从，谁是谁的主，谁是谁的从

成功标识

[root@VM-24-10-centos redis-cluster]# redis-cli -a pwd@2022gblfy --cluster create --cluster-replicas 1 192.168.0.80:7001 192.168.0.80:7004 192.168.0.80:7003 192.168.0.80:7006 192.168.0.80:7005 192.168.0.80:7002
