Redis的一主二从三哨兵搭建【五种安装方式，助你无痛拿下Redis】

Redis的一主二从三哨兵搭建

五种安装方式

  1. 网络源安装
  2. 源码包安装
  3. 容器安装
  4. shell安装
  5. ansible安装

1、网络源安装

主机名 IP OS
master 192.168.96.210 Centos8.4
slave1 192.168.96.211 Centos8.4
slave2 192.168.96.212 Centos8.4

1、安装软件包（所有节点操作）

yum install redis*  -y

2、关闭防火墙和selinux （所有节点操作）

systemctl disable --now  firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

3、修改master配置文件

打开配置文件

vim /etc/redis.conf

修改参数

bind 192.168.96.210  192.168.96.211 192.168.96.212  # redis客户端监听的地址,把bind修改为0.0.0.0表示允许所有远程访问
port 6379     # redis进程的端口号
protected-mode no   # 是否开启保护模式，如果开启，则只监听本地地址
daemonize yes  # redis进程是否以守护进程的方式运行，yes为是，no为否。默认为no(不以守护进程的方式运行会占用一个终端)。
logfile /var/log/redis/redis.log # redis日志文件保存位置
requirepass redhat 设置redis连接密码，如果配置了连接密码，客户端在连接redis是需要通过AUTH<password>命令提供密码，默认关闭
masterauth redhat  # 当master设置了密码保护时，slave服务连接master的密码

4、修改slave配置文件（两台从节点都要操作）

打开配置文件

vim /etc/redis.conf

修改参数

bind 0.0.0.0
protected-mode no
port 6380
daemonize yes
logfile /var/log/redis/redis.log
masterauth redhat
requirepass redhat
replicaof 192.168.96.210 6379

5、开启服务并验证

systemctl enable --now  redis

master

redis-cli -h 192.168.96.210 -a redhat -p 6379

6、哨兵模式（sentinel）

Redis Sentinel是Redis 的高可用性解决方案，由一个或多个Sentinel（哨兵）实例组成。它可以监视任意多个主服务器，以及这些主服务器属下的所有从服务器，并在被监视的主服务器进入下线状态时，自动将下线主服务器属下的某个从服务器升级为新的主服务器，它的主要功能如下：

  1. 监控(Monitoring)： Sentinel会不断地检查你的主服务器和从服务器是否运作正常。
  2. 通知(Notification)： 当被监控的某个 Redis 服务器出现问题时， Sentinel可以通过API向管理员或者其他应用程序发送通知。
  3. 故障迁移： 当主服务器不能正常工作时，Sentinel会自动进行故障迁移，也就是主从切换。
  4. 统一的配置管理： 连接者询问sentinel取得主从的地址。
1、master节点sentinel的配置

修改配置文件

vim /etc/redis-sentinel.conf

修改参数

port 26379 # 哨兵模式使用的端口
daemonize yes  # 是否要在后端运行
dir /tmp # 哨兵模式的工作目录
protected-mode no # 是否开启保护模式
logfile "" # 当进程在后台运行的时候，直接将日志传输到/dev/null，但是这里不写"",最好写一个固定的文件
logfile /var/log/redis/redis-sentinel.log
sentinel monitor master 192.168.96.210 6379 2 # 修改master的名字，ip和端口，并且设置当有两个slave节点认为master挂掉的时候，就重新选举
sentinel auth-pass master redhat  #在Redis实例中开启了requirepass，这里就需要提供密码。
sentinel down-after-milliseconds master 3000  #这里设置了主机有多久没响应就认为主机怪掉了
sentinel parallel-syncs master 1 #主备切换时候，有多少slave想master同步
sentinel failover-timeout master 180000 # 故障转移超时时间

【注意：以上所有的master都必须要是主节点的主机名】
2、slave节点sentinel的配置

修改配置文件

vim /etc/redis-sentinel.conf

修改参数

port 26379 # 哨兵模式使用的端口
daemonize yes  # 是否要在后端运行
dir /tmp # 哨兵模式的工作目录
protected-mode no # 是否开启保护模式
logfile "" # 当进程在后台运行的时候，直接将日志传输到/dev/null，但是这里不写"",最好写一个固定的文件
logfile /var/log/redis/redis-sentinel.log   # 如果报错，那么就还是""
sentinel monitor master 192.168.96.210 6379 2 # 修改master的名字，ip和端口，并且设置当有两个slave节点认为master挂掉的时候，就重新选举
sentinel auth-pass master redhat  #在Redis实例中开启了requirepass，这里就需要提供密码。
sentinel down-after-milliseconds master 3000  #这里设置了主机有多久没响应就认为主机怪掉了
sentinel parallel-syncs master 1 #主备切换时候，有多少slave想master同步
sentinel failover-timeout master 180000 # 故障转移超时时间

【注意：以上所有的master都必须要是主节点的主机名】

可以这样配置，也可以直接从master传输文件过去

3、重启服务并验证【三个节点都执行】
systemctl restart redis  # 重启服务
systemctl enable --now redis-sentinel.service
[root@master ~]# redis-cli  -h 192.168.96.210  -a redhat -p 26379
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.
192.168.96.210:26379> info sentinel
# Sentinel
sentinel_masters:1
sentinel_tilt:0
sentinel_running_scripts:0
sentinel_scripts_queue_length:0
sentinel_simulate_failure_flags:0
master0:name=master,status=ok,address=192.168.96.210:6379,slaves=2,sentinels=3

2、源码包安装【7.0.14】

1、下载并解压源码包【三节点执行】

wget https://github.com/redis/redis/archive/refs/tags/7.0.14.tar.gz
tar -xvf 7.0.14.tar.gz

2、创建redis存放目录【三节点执行】

mkdir /usr/local/redis
mv redis-7.0.14 /usr/local/redis/
cd /usr/local/redis/redis-7.0.14/

3、关闭防火墙和selinux【三节点执行】

systemctl disable --now firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

3、安装解析【三节点执行】

yum install make gcc gcc-c++ -y

4、编译安装【三节点安装】

make
cd /src
make install

5、验证

在编译安装完成后，他默认安装到/usr/local/bin下

redis-server -v
redis-sentinel -v

6、将redis做成服务

将redis-server做成服务

vim /usr/lib/systemd/system/redis.service

[Unit]
Description=redis-server
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/redis-server  /usr/local/redis/redis-7.0.14/redis.conf
# 写自己的文件路径
PrivateTmp=true
[Install]
WantedBy=multi-user.target

将redis-sentinel做成服务

vim /usr/lib/systemd/system/redis-sentinel.service

[Unit]
Description=redis-sentinel
After=network.target

[Service]
Type=forking
ExecStart=/usr/local/bin/redis-sentinel  /usr/local/redis/redis-7.0.14/sentinel.conf
修改成自己的地址
PrivateTmp=true
[Install]
WantedBy=multi-user.target

7、修改配置文件【redis.conf】（三节点执行）

master参数

bind 0.0.0.0
protected-mode no
daemonize yes
logfile ./redis.log
masterauth redhat
requirepass redhat

slave参数

bind 0.0.0.0
protected-mode no

9、哨兵模式

1、修改配置文件【sentinel.conf】(三节点)

master参数

protected-mode no
port 26379
daemonize yes
logfile ./sentinel.log
sentinel monitor master 192.168.96.210 6379 2
sentinel auth-pass master redhat
sentinel down-after-milliseconds master 3000

sentinel failover-timeout master 180000

2、启动服务并验证

systemctl enable --now redis-sentinel.service

master

[root@master redis-7.0.14]# redis-cli -h 127.0.0.1 -a redhat -p 26379 
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

3、容器安装

1、配置docker并关闭防火墙、selinux【三节点执行】

安装docker

yum install -y yum-utils
yum-config-manager --add-repo https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
yum install -y docker-ce
systemctl enable --now docker

关闭防火墙和selinux

systemctl disable --now firewalld
setenforce 0
sed -i 's/SELINUX=enforcing/SELINUX=disabled/g' /etc/selinux/config

2、拉取redis镜像【三节点执行】

docker pull uhub.service.ucloud.cn/variety/redis:7.0.14

3、运行镜像【三节点执行】

由于我们拉取的镜像，他默认位置redis.conf文件不存在，所以，我们给定一个外部的配置文件，让容器运行

master

创建文件和目录

mkdir /opt/redis
touch /opt/redis/redis.conf
mkdir /opt/redis/data

redis.conf参数

bind 0.0.0.0
protected-mode no
daemonize no
loglevel notice
port 6379
tcp-backlog 2048
databases 16
dir /data
masterauth redhat
requirepass redhat
maxclients 10000
timeout 600
tcp-keepalive 600
slowlog-log-slower-than 1000
slowlog-max-len 128
maxmemory 1gb
maxmemory-policy allkeys-lru
dbfilename dump.rdb
save 900 1
save 300 10
save 60 10000
stop-writes-on-bgsave-error yes
rdbcompression yes
rdbchecksum yes
replicaof 192.168.96.210 6379

运行容器

docker run -tid --name redis-master --privileged  -v /opt/redis/redis.conf:/etc/redis/redis.conf:Z  -v /opt/redis/data/:/data:Z  --restart always  --network host  --entrypoint redis-server   uhub.service.ucloud.cn/variety/redis:7.0.14   /etc/redis/redis.conf

--entrypoint redis-server 在这里指定了entrypoint，覆盖掉原本的entrypoint，以便于我们链接的文件生效

修改文件权限

docker exec -it redis-node /bin/bash -c "chown redis:redis /etc/redis/redis.conf"

slave

创建文件和目录

mkdir /opt/redis
touch /opt/redis/redis.conf
mkdir /opt/redis/data

redis.conf参数

修改文件权限

docker exec -it redis-slave /bin/bash -c "chown redis:redis /etc/redis/redis.conf"

4、验证

master

docker exec  -ti redis-master /bin/bash

root@master:/data# redis-cli -p 6379 -a redhat 
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

5、哨兵模式

1、创建配置文件

touch /opt/redis/redis-sentinel.conf

2、运行容器

master

bind 0.0.0.0
port 26379
daemonize no
pidfile "/var/run/redis-sentinel.pid"
logfile "/var/log/sentinel_26379.log"
dir "/tmp"
sentinel monitor master 192.168.96.210 6379 2       
sentinel auth-pass master redhat                 
sentinel down-after-milliseconds master 3000    
sentinel parallel-syncs master 1
sentinel failover-timeout master 180000
sentinel deny-scripts-reconfig yes

运行容器

docker run -tid --name redis-sentinel --restart always --privileged  -v /opt/redis/redis-sentinel.conf:/etc/redis/redis-sentinel.conf:Z  --network host --entrypoint redis-sentinel uhub.service.ucloud.cn/variety/redis:7.0.14  /etc/redis/redis-sentinel.conf

slave

bind 0.0.0.0
port 26379
daemonize no
pidfile "/var/run/redis-sentinel.pid"
logfile "/var/log/sentinel_26379.log"
dir "/tmp"

3、验证

docker exec -ti redis-sentinel /bin/bash

127.0.0.1:26379> info sentinel
# Sentinel
sentinel_masters:1
sentinel_tilt:0
sentinel_tilt_since_seconds:-1

sentinel_simulate_failure_flags:0
master0:name=master,status=ok,address=192.168.96.210:6379,slaves=2,sentinels=3

4、shell安装redis

这里shell安装使用tar包安装

#!/bin/bash
