Linux下部署redis、启动redis、创建redis节点集群
2024-04-12 22:12:02
目录
- 1. 准备工作
- 2. 启动redis
- 3. 查看redis是否启动成功
- 4. 创建redis集群
- 5. 连接redis
- 6. 查看集群状态
- 7. 通过set和get方法插入和查询
- 总结：
1. 准备工作
a.集群redis包
下载
b.下载的包中有6个redis节点，端口7001、7002、7003、7004、7005、7006，使用时请注意端口是否占用,密码为123455
c.如果需要修改端口和密码，可以在/data/redis-cluster/7001/etc/redis.conf配置文件中修改
[root@wanwan redis-cluster]# cat /data/redis-cluster/7001/etc/redis.conf
#redis密码
requirepass 123456
#redis端口
port 7001
2. 启动redis
通过start_all.sh脚本批量启动所有redis，通过stop_all.sh脚本批量关闭redis
[root@wanwan redis-cluster]# pwd
/data/redis-cluster
[root@wanwan redis-cluster]# ll

[root@wanwan bin]# 5. 连接redis
本机连接不需要输入ip地址，如果是远程连接需要加-h ip
[root@wanwan bin]# ./redis-cli -a 123456 -p 7001
Warning: Using a password with '-a' or '-u' option on the command line interface may not be safe.

6. 查看集群状态
集群创建成功==》cluster_state:ok
集群未创建==》cluster_state:fail
127.0.0.1:7001> cluster info
cluster_state:ok
cluster_slots_assigned:16384

7. 通过set和get方法插入和查询
尝试redis是否能否正常使用，通过set插入缓存数据，通过get获取缓存数据
127.0.0.1:7001> set key12345 value12345
OK
127.0.0.1:7001> get key12345
"value12345"
127.0.0.1:7001>
