环境
- EMQX 版本：5.8.2
- 操作系统版本：ubuntu
我们在etcd上开启了ssl，参考了相关配置集群配置 | EMQX 5.8 文档
配置：
cluster {
name = "daily"
discovery_strategy = "etcd"
etcd {
server = "https://10.37.49.17:2379,https://10.37.50.230:2379,https://10.37.51.33:2379"
prefix = "2"
node_ttl = 1m
ssl_options {
keyfile = "/home/www/etcd-common-c0/client-key.pem"
cacertfile = "/home/www/etcd-common-c0/ca.pem"
certfile = "/home/www/etcd-common-c0/client.pem"
}
}
}
然后启动会报错
