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)
