PHP Invalid configuration

[centminmod]

Not sure what I am doing wrong with /root/tools/unitconfigs/phpstart.json

{
     "listeners": {
         "*:8300": {
             "application": "php56domaincom"
         }
     },
     "applications": {
         "php56domaincom": {
             "type": "php",
              "workers": 10,
              "root": "/home/nginx/domains/domain.com/public",
              "user": "nginx",
              "group": "nginx",
              "index": "index.php"
         }
     }
}

curl -X PUT -d @/root/tools/unitconfigs/phpstart.json --unix-socket /var/run/control.unit.sock http://localhost/ 
{
        "error": "Invalid configuration."
}

curl --unix-socket /var/run/control.unit.sock http://localhost/
{
        "listeners": {},
        "applications": {}
}

What is in unit.log ?

[VBart]

More detailed errors in case of invalid configuration will be ready soon.

As of now, since your configuration on my system applies without a problem, there are only two possibilities: there's no nginx user with nginx group on your system or the php module is not found in the configured modules directory.

[VBart]

Well, in your case, it's very likely that the configuration is invalid because of wrong path to the modules directory. As I see from #43, you have unit modules path: "build" configured, but the php module was installed into /opt/unitbuild/ using DESTDIR.

thanks, the unit log confirms module path error

thanks with fixed Unit configure setup it's working now

curl -X PUT -d @/root/tools/unitconfigs/phpstart.json --unix-socket /opt/unit/control.unit.sock http://localhost/

curl -X PUT -d @/root/tools/unitconfigs/phpstart.json --unix-socket /opt/unit/control.unit.sock http://localhost/
{
        "success": "Reconfiguration done."
}

curl --unix-socket /opt/unit/control.unit.sock http://localhost/
{
        "listeners": {
                "*:8300": {
                        "application": "php56domaincom"
                }
        },

        "applications": {
                "php56domaincom": {
                        "type": "php",
                        "workers": 10,
                        "root": "/home/nginx/domains/domain.com/public",
                        "user": "nginx",
                        "group": "nginx",
                        "index": "index.php"
                }
        }
}

though I get failed to store current configuration

looks like /opt/unit/state directory wasn't created.. manually creating seems to fix it

ls -lah state/
total 4.0K
drwxr-xr-x 2 root root  22 Sep 23 10:28 .
drwxr-xr-x 6 root root  78 Sep 23 10:28 ..
-rw------- 1 root root 217 Sep 23 10:28 conf.json

cat state/conf.json 
{"listeners":{"*:8300":{"application":"php56domaincom"}},"applications":{"php56domaincom":{"type":"php","workers":10,"root":"/home/nginx/domains/domain.com/public","user":"nginx","group":"nginx","index":"index.php"}}}

[VBart]

Igor suggested --prefix=/opt/unit --state=state and that configures /opt/unit/state path as the internal state storage for unit daemon.

In this case, the /opt/unit/state directory need to be created and be writable by the main process.

[VBart]

If you compile unit with the --debug option, you will see more information about what's wrong.

thanks @VBart for clarification :)
