Redis集群——Redis高可用集群添加密码

太过爱你忘了你带给我的痛 2022-03-15 04:50 1043阅读 0赞

线上环境的redis集群肯定要有密码的，今天介绍一下redis-cluster如何配置密码

第一步，修改每个redis-700x.conf配置文件，注意密码必须一致

  1. masterauth 123456
  2. requirepass 123456

第二步，删除每个节点的配置文件

注意，如果你使用redis-trib.rb命令会提示无法连接，如

[root@localhost src]# ./redis-trib.rb check 192.168.1.10:7001
[ERR] Sorry, can’t connect to node 192.168.1.10:7001
通过find / -name ‘client.rb’命令找到文件位置

修改第三个文件

再重试命令就正常了

[root@localhost src]# ./redis-trib.rb check 192.168.1.10:7001

Performing Cluster Check (using node 192.168.1.10:7001)
M: 367899876fc08d3475646b8890fb14f6877c7b95 192.168.1.10:7001
slots: (0 slots) master
0 additional replica(s)
[OK] All nodes agree about slots configuration.
Check for open slots…
Check slots coverage…
[ERR] Not all 16384 slots are covered by nodes.
第三步，重启集群

  1. ./redis-trib.rb create --replicas 1 192.168.1.10:7001 192.168.1.11:7002 192.168.1.12:7003 192.168.1.10:7004 192.168.1.11:7005 192.168.1.12:7006

第四步，测试

[root@localhost src]# ./redis-trib.rb check 192.168.1.10:7001

Performing Cluster Check (using node 192.168.1.10:7001)

[root@localhost src]#
第五步，带密码访问集群

  1. ./redis-cli -c -h 192.168.1.10 -p 7001 -a 123456

[root@localhost redis-4.0.1]# redis-cli -c -h 192.168.1.10 -p 7001 -a 123456
192.168.1.10:7001> keys *
(empty list or set)
192.168.1.10:7001>
