redis集群有密码无法使用吗？

有没有安装过程和使用例子呢？看了下好像需要编译一个C文件。

[error] 48643#0: *67 lua entry thread aborted: runtime error: attempt to yield across C-call boundary

code

    if ngx.ctx.cache == nil then
        ngx.ctx.cache = redis_cluster:new(config.redis_config)
    end
    local v, err = ngx.ctx.cache:get(key)

In the case of concurrent will appear such mistakes

2016/05/27 09:52:12 [error] 32291#0: *30184 lua entry thread aborted: runtime error: /opt/apps/zkv/lua/resty/rediscluster.lua:217: bad request

The resty.redis object instance cannot be stored in a Lua variable at the Lua module level，
result in bad race conditions when concurrent requests are trying to use the same resty.redis instance (you would see the "bad request" or "socket busy" error to be returned from the method calls).

How should I solve this problem?

thx

你这个是在new的时候把集群信息获取到。如果在new之后，某个分片挂掉了，（刚好需要使用哪个上面的分片数据）那么client就用不了了。
请问这个问题需要怎么解决？即客户端如何及时感知集群的状态变化？

问题描述：
1、源码中没有开启expire，当被调用设置有效期时，报错：
2020/07/12 15:58:01 [error] 9873#0: *248 lua entry thread aborted: runtime error: /apps/nginx/conf/waf/waf.lua:168: attempt to call method 'expire' (a nil value)
stack traceback:
coroutine 0:
2、rediscluster 放开注释的expire命令时候不跑错了，但是设置的key都没有过期时间。

现在需要怎么改进解决下这个问题，请教作者还有各位大神回复，谢谢

Still a work in progress yes but very promising @cuiweixie!
It will be shared in our next RedisWeekly!

有个问题请教下，212行的变量redis_client为全局变量，导致并发根本不行，2个并发都有失败的请求，还有个问题，commands好多redis的命令为何注释掉了，尤其是"del"。
