php predis password,Redis Cluster 已运行的Redis集群 设置密码 Predis 连接

按照之前写过的无密码redis集群搭建，环境已经搭建好了，现在需要远程连接，并设置连接密码

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7000

cluster info 命令显示 集群状态cluster_state:ok ，集群配置主从关系如上面cluster nodes命令显示的：

10.10.10.171:7000 #主

10.10.10.171:7001 #主

10.10.10.171:7002 #主

10.10.10.171:7003 #从

10.10.10.171:7004 #从

10.10.10.171:7005 #从

确认好Redis集群已运行，现在给Redis集群加密码

主：config set requirepass 123456设置密码

从：config set masterauth 123456设置密码

123456可替换成你想设置的任何密码

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7000

10.10.10.171:7000> config set requirepass 123456

OK

10.10.10.171:7000> exit

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7001

10.10.10.171:7001> config set requirepass 123456

OK

10.10.10.171:7001> exit

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7002

10.10.10.171:7002> config set requirepass 123456

OK

10.10.10.171:7002> exit

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7003

10.10.10.171:7003> config set masterauth 123456

OK

10.10.10.171:7003> exit

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7004

10.10.10.171:7004> config set masterauth 123456

OK

10.10.10.171:7004> exit

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7005

10.10.10.171:7005> config set masterauth 123456

OK

10.10.10.171:7005> exit

#用 -a 密码 连接(这里输入一个错误的密码:testpassword测试一下)

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7000 -a testpassword

# 如果密码错误，虽然也能连上，但没有执行命令权限

10.10.10.171:7000> cluster nodes

NOAUTH Authentication required.

10.10.10.171:7000> exit

#退出重新输入正确密码

[root@localhost src]# ./redis-cli -c -h 10.10.10.171 -p 7000 -a 123456

10.10.10.171:7000> cluster info

cluster_state:ok

cluster_slots_assigned:16384

cluster_slots_ok:16384

cluster_slots_pfail:0

cluster_slots_fail:0

cluster_known_nodes:6

cluster_size:3

cluster_current_epoch:6

cluster_my_epoch:1

cluster_stats_messages_sent:11566

cluster_stats_messages_received:11566

至此一切正常，已运行的redis集群加密码就这么简单

再用Predis远程连接测试 (predis：https://github.com/nrk/predis)
