Nginx unit requires using port 80 for initial setting?

I installed Nginx unit

systemctl status unit
● unit.service - NGINX Unit
     Loaded: loaded (/lib/systemd/system/unit.service; enabled; vendor preset: enabled)
     Active: active (running) since Thu 2021-09-02 15:33:30 JST; 4min 29s ago
    Process: 2288597 ExecStart=/usr/sbin/unitd $DAEMON_ARGS (code=exited, status=0/SUCCESS)
   Main PID: 2288600 (unitd)
      Tasks: 3 (limit: 2282)
     Memory: 5.6M
     CGroup: /system.slice/unit.service
             ├─2288600 unit: main v1.25.0 [/usr/sbin/unitd]
             ├─2288613 unit: controller
             └─2288614 unit: router

Sep 02 15:33:30 tk2-243-31156 systemd[1]: Starting NGINX Unit...
Sep 02 15:33:30 tk2-243-31156 unitd[2288597]: 2021/09/02 15:33:30 [info] 2288597#2288597 unit started
Sep 02 15:33:30 tk2-243-31156 systemd[1]: Started NGINX Unit.

Now,I try to first test

sudo curl --unix-socket /var/run/unit/control.sock http://localhost/

However it returns curl: (7) Couldn't connect to server

I guess on this service apache works ,so port 80 is used....

Is there any work around??

You can communicate via Unix socket without opening an additional network (IP) socket, e.g. on port 80. Doublecheck your Unix socket path, if it is really /var/run/unit/control.sock.

If I use a non-existing path, e.g.:

/var/run/nonexisting.sock

I get the same error:

curl: (7) Couldn't connect to server

When I run the following command:

sudo curl -X GET --unix-socket /var/run/control.unit.sock http://localhost/status

curl connects to Unix socket and use the HTTP URL to address the REST API behind it. It doesn't use the port 80.

You should get a similar response:

{
    "connections": {
        "accepted": 0,
        "active": 0,
        "idle": 0,
        "closed": 0
    },
    "requests": {
        "total": 0
    },
    "applications": {}
}
