Sync_gateway illegal user name

Mobile Sync Gateway
1

When I try to install sync gateway using the command, $ sudo ./sync_gateway_service_install.sh
as per following this URL, Couchbase Capella for Mobile Developers

I am getting the following illegal user name error in Terminal. I am installing on MacBook. What does this error mean? I have sync_gateway folder created under ‘users’ and there are folders like ‘data’, ‘logs’ and sync_gateway.json file there.
What does this sync_gateway folder mean? Does this a bucket name similar to given in server? Why does this error ‘illegal user name’ come?

MyMacbook:service administrator$ sudo ./sync_gateway_service_install.sh
Password:
chown: sync_gateway: illegal user name
chown: sync_gateway: illegal user name
MyMacbook:service administrator$

I’m not sure why this is happening (attn @traun ) .

In the mean time, you can start it from the command prompt instead of as a service. From the directory where you unzipped Sync Gateway, run:

~/Downloads/couchbase-sync-gateway/bin/sync_gateway <path_to_optional_sync_gateway_config.json>
3

Sure, I’ll try. I am using MacBook. Path to sync gateway config.json is the one I have it in “Users/sync_gateway/sync_gateway.json” ? or It might be somewhere else?

Users/sync_gateway/sync_gateway.json: contains the following data.
{
“log”: [“HTTP+”],
“adminInterface”: “127.0.0.1:4985”,
“interface”: “0.0.0.0:4984”,
“databases”: {
“db”: {
“server”: “walrus:data”,
“users”: {
“GUEST”: {“disabled”: false, “admin_channels”: ["*"] }
}
}
}
}
Do I need to modify this with my server bucket DB name, server?

Sure, I’ll try. Path to sync gateway config.json is the one I have it in Users/sync_gateway/sync_gateway.json ?

No, in this case it’s the relative path. Create the sync-gateway-config.json file in the bin directory and then run ~/Downloads/couchbase-sync-gateway/bin/sync_gateway sync-gateway-config.json.

I created a empty “sync-gateway-config.json” in " ~/Downloads/couchbase-sync-gateway/bin". and run this command. Here is the result,

Bucket name may be causing with this error? Where Can I change bucket name? I don’t have bucket name like “db” in Couchbase server. I have default bucket names “travel-sample” etc.
Couchbase server is running fine.

you can follow this section to connect Sync Gateway to Couchbase Server

Thanks, but I followed the same. Here is my “sync-gateway-config.json” in " ~/Downloads/couchbase-sync-gateway/bin"

Please ignore my previous comments. Now I got ‘server starting …’ message,

I think the sync gateway and server is running fine. I am trying to run sample project > GrocerySync. In the sample > GrocerySync iOS project, i modified like below,
#define kDatabaseName @“travel-sample”
#define kServerDbURL @“http://localhost:4984/travel-sample/”

and, also modified “sync_gateway_config.json” which is inside this project,

{
“log”: [“HTTP+”],
“databases”: {
“db”: {
“server”: “http://localhost:8091”,
“bucket”: “travel-sample”,
“users”: {
“GUEST”: {“disabled”: false, “admin_channels”: [“*”] }
}
}
}
}

**> But i see the log as , **
> 2017-04-25T11:47:09.184-05:00 HTTP: #002: POST /travel-sample/_revs_diff
> 2017-04-25T11:47:09.184-05:00 HTTP: #002: → 404 no such database “travel-sample” (0.3 ms)

In case you haven’t figured this out already -
The “db” under “databases” in the sync_gateway_config.json file refers to the name of the database. So, you will have to replace “db” with “travel-sample” (the name of your new database) and restart the Sync Gateway.

Thank you, I’ll try changing the DB name instead of “db”

Running into the same problem SG 1.5. Pointing to Couchbase-Server 5.0 with travel-sample bucket. Tried just the bucket as travel-sample, and then also the db as travel-sample.

The sync_gateway.json looks like this now:

{
“log”: [“HTTP+”],
“adminInterface”: “127.0.0.1:4985”,
“interface”: “0.0.0.0:4984”,
“databases”: {
“travel-sample”: {
“server”:“http://localhost:8091”,
“bucket”:“travel-sample”,
“users”: {
“GUEST”: {“disabled”: false, “admin_channels”: ["*"] }
}
}
}
}

Still get the following:
chown: sync_gateway: illegal user name
chown: sync_gateway: illegal user name

15

Assumed you configured a user on the Couchbase server to access the travel-sample bucket, specify that in your Sync GW config file …

"server": "http://localhost:8091",
"username": "<replace_with_username>",
"password": "<replace_with_password>",
16

Thanks Priya. I am using the out-of-box Docker-based sample, for which I added default admin credentials into the travel-sample db. Same results. Do I need to create a different user and grant access to the bucket?

17

OK, for my clarification -

  • You have this admin user configured under Settings->users tab on Couchbase server admin console
  • And you specified that user name/credentials in the Sync Gateway config file as well (as indicated earlier)

And you are still seeing issues?

18

I uninstalled the Docker instance of Couchbase-Server 5.0, and installed it just as an app. Noticed that each bucket now requires a user. The default admin account did not show up under Users, so I created one, and gave full bucket access to the travel-sample bucket.That is the only permission I gave the new user.

Then I restarted sync gateway with the new user’s credentials. The admin port started, but it hasn’t connected to Couchbase Server. The new error is:

go-couchbase: TAP connection lost; reconnecting to bucket “travel-sample” in 1s

Thanks for helping me out, Priya.

I am running into the same issue. I just followed the instructions at https://developer.couchbase.com/documentation/mobile/2.0/installation/sync-gateway/index.html
and when running the *install.sh script I get:

chown: sync_gateway: illegal group name
chown: sync_gateway: illegal user name
chown: sync_gateway: illegal user name

I’m also OSX High Sierra.

20

This is an issue with accounts on your system. By default, the install script expects to set everything up to run as user “sync_gateway”, but it doesn’t create the actual user account for you.

You can either create an account to run under, or just run it as yourself. Specify the account with the --runas option.

I created a gist showing how to set up a user dedicated to running Sync Gateway here
