EMQX 4.x 版本的时候还有8081端口,不过在EMQX 5.x时,被合并到18083
常规的用法,我们一般使用和开放这两个端口:
因为开放,所以风险。
默认的端口号往往会引来很频繁的扫描攻击。
于是,我们要这么做:
配置文件修改/etc/emqx/emqx.conf
listeners.tcp.default {
# bind = "0.0.0.0:1883"
bind = "0.0.0.0:2883"
max_connections = 1024000
}
dashboard {
listeners.http {
# bind = 18083
bind = 28083
}
default_username = "admin"
default_password = "public"
}
emqx restart 好像在5.x版本之后不能用了,只能先stop再start
[root@iZ2ze30dygwd6yh7gu6lskZ emqx]# emqx stop
ok
[root@iZ2ze30dygwd6yh7gu6lskZ emqx]# emqx start
EMQX 5.0.7 is started successfully!
[root@iZ2ze30dygwd6yh7gu6lskZ emqx]# netstat -nplt
