celery启动异常: ERROR/MainProcess] c

错误提示

[2019-06-25 12:32:31,272: ERROR/MainProcess] consumer: Cannot connect to redis://ali2.teeh.cn:6379/8: DENIED Redis is running in protected mode because protected mode is enabled, no bind address was specified, no authentication password is requested to clients. In this mode connections are only accepted from the loopback interface. If you want to connect from external computers to Redis you may adopt one of the following solutions: 1) Just disable protected mode sending the command 'CONFIG SET protected-mode no' from the loopback interface by connecting to Redis from the same host the server is running, however MAKE SURE Redis is not publicly accessible from internet if you do so. Use CONFIG REWRITE to make this change permanent. 2) Alternatively you can just disable the protected mode by editing the Redis configuration file, and setting the protected mode option to 'no', and then restarting the server. 3) If you started the server manually just for testing, restart it with the '--protected-mode no' option. 4) Setup a bind address or an authentication password. NOTE: You only need to do one of the above things in order for the server to start accepting connections from the outside..

解决办法

• 1、查找redis的配置文件

find / -name 'redis.conf'

• 2、进入redis的配置文件中:

vi redis.conf

• 3、打开配置文件把下面对应的注释掉

# bind 127.0.0.1

• 4、保护模式

protected-mode no

• 5、最后关键的是：

没反应应该是你启动服务端的时候没有带上配置文件。你可以./redis-server redis.conf
你配置好了，但要重新启动redis,如果还是报一样的错误，很可能是没有启动到配置文件，所以需要真正的和配置文件启动需要：

在redis.conf文件的当前目录下

redis-server redis.conf

如果还是所某个端口已在使用，那么可能是有 后台程序在占用该端口，需要kill 掉该程序，重新带上配置文件。./redis-server redis.conf启动。
将含有”redis”关键词的进程杀死:

ps -ef | grep redis | awk ‘{print $2}’ | xargs kill -9
