我有一个将 Redis 作为 ActionCable 适配器的 Rails API。
我只使用 ActionCable 作为整个系统的一部分进行简单的聊天。
一切都很完美，我可以订阅、发送消息、接收消息。服务器启动 5 分钟后出现问题，我在 redis gem 中收到 ECONNRESET 错误：连接丢失 (ECONNRESET) (Redis::ConnectionError)
自从我开始尝试解决这个问题已经 3 天了，我尝试更改 redis-server 配置，我尝试更改 redis 在 rails 应用程序上初始化的方式，我尝试更改 cable.yml 配置，我已经尝试更改 actioncable 配置，但似乎没有任何方法可以解决这个问题，我的想法已经不多了。
我也无法挽救这个异常，它只会破坏整个 rails 应用程序，这是我无法解决的另一件事，这太令人沮丧了。
顺便说一句，我正在开发环境中进行测试。
这是我的电缆配置：
production:
adapter: redis
url: redis://192.168.1.6:6379
development:
adapter: redis
url: redis://192.168.1.5:6379
channel_prefix: ChatChannel
timeout: 30
max_conns: 8000
max_persistent_conns: 8000
test:
adapter: async
这是我的 redis 初始化程序：
require 'redis'
## Added rescue condition if Redis connection is failed
begin
puts "CREATING NEW INSTANCE OF REDIS"
$redis = Redis.new(
:host => "192.168.1.5",
:port => 6379,
:reconnect_attempts => 10,
:reconnect_delay => 1.5,
:reconnect_delay_max => 10.0
)
$redis.ping
rescue Errno::ECONNRESET => e
puts "THERE WAS AN ERROR"
puts e
end
这是 rails 应用程序的输出：
