1. 部署划分
| IP | 角色 | 端口 |
| 192.168.45.80 | Master | 6380 |
| 192.168.45.80 | Slave | 6381 |
| 192.168.45.80 | Slave | 6382 |
2. 单机安装Redis
首先在在3台服务器上分别安装Redis单机环境
Linux环境 安装 Redis-6.2.6 配置运行_01
3. 创建配置/数据/日志目录
- 创建配置目录+数据目录+日志目录
mkdir /usr/local/redis/conf/redis01 -p
mkdir /usr/local/redis/conf/redis02 -p
mkdir /usr/local/redis/conf/redis03 -p
mkdir /usr/local/redis/data/redis01 -p
mkdir /usr/local/redis/data/redis02 -p
mkdir /usr/local/redis/data/redis03 -p
mkdir /usr/local/redis/log/redis01 -p
mkdir /usr/local/redis/log/redis02 -p
mkdir /usr/local/redis/log/redis03 -p 4. 修改配置文件
vim /usr/local/redis/conf/redis01/redis-6380.conf - master主节点配置
# 放行访问IP的限制 多个用空格隔开
# 0.0.0.0 代表无限制
bind 0.0.0.0
# 后台启动开启
daemonize yes
# 日志存储目录以及日志文件名
logfile "/usr/local/redis/log/redis01/redis.log"
# rdb数据文件名
dbfilename dump.rdb
# aof模式开启
appendonly no
# aof数据文件名
appendfilename "appendonly.aof"
#rdb数据文件和aof数据文件存储目录
dir /usr/local/redis/data/redis01
# 设置密码
requirepass 123456
# 从节点访问主节点的密码(必须和requirepass 一致)
masterauth 123456
#从节点只读模式
replica-read-only yes
# 端口
port 6380 - slave01配置
vim /usr/local/redis/conf/redis02/redis-6381.conf # 放行访问IP的限制 多个用空格隔开

# 从节点访问主节点的密码(必须和requirepass 一致)

port 6381
# 从节点从属于那个主节点
slaveof 192.168.45.80 6380 - slave02配置
vim /usr/local/redis/conf/redis03/redis-6382.conf # 放行访问IP的限制 多个用空格隔开

slaveof 192.168.45.80 6380 5. 防火墙开放
firewall-cmd --zone=public --add-port=6380/tcp --permanent
firewall-cmd --zone=public --add-port=6381/tcp --permanent
firewall-cmd --zone=public --add-port=6382/tcp --permanent
firewall-cmd --reload 
6. redis启动
/app/redis-6.2.6/src/redis-server /usr/local/redis/conf/redis01/redis-6380.conf
/app/redis-6.2.6/src/redis-server /usr/local/redis/conf/redis02/redis-6381.conf
/app/redis-6.2.6/src/redis-server /usr/local/redis/conf/redis03/redis-6382.conf 7. 查看redis状态
ps -ef |grep redis [root@VM-24-10-centos redis03]# ps -ef |grep redis
root 14763 1 0 14:39 ? 00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:6380
root 14779 1 0 14:39 ? 00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:6381
root 14834 1 0 14:39 ? 00:00:00 /app/redis-6.2.6/src/redis-server 0.0.0.0:6382 8. 登录查看信息
