I’m trying to set up a local development environment and am getting stuck with database issues. Any help is appreciated. Running OS X 10.11 Gotten through the setup instructions but when I run `make run` I get the following: ``` ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) ldap_sasl_bind(SIMPLE): Can't contact LDAP server (-1) make: *** [start-docker] Error 255 ``` When I try `make clean-docker,` then `make start-docker`, then `make run-server`, I get this: ``` [2016/11/16 06:38:42 EST] [INFO] Server is initializing...

Hi @fraziern, Are you running Docker for Mac or Docker Toolbox? Depending on which you’re using, you’ll need to map `dockerhost` to a different address in `/etc/hosts`. - If you’re using Docker for Mac, the first two steps of the [latest dev setup instructions](https://docs.mattermost.com/developer/developer-setup.html#mac-os-x) cover what you need to do - If you’re on using Docker Toolbox, you’ll need to: 1. Find out what IP address docker-machine is running on using `docker-machine ip dev` 2. Add ` dockerhost` to your `/etc/hosts` file. ---

Thanks @hmhealey - I am using Docker for Mac, and had setup /etc/hosts previously. I seem to be up and running now, though, after running `make run` several times in a row. Not sure what the issue is/was, but for now I’m good. Thanks again. ---

@fraziern, thanks for posting back! I’ll mark this issue solved for now but if you run into problems again, please feel free to post back. ---

I have the same issue, but on a linux debian machine. I ran into the problem when I first ran make run, but I managed to get passed it without really knowing how. I did a make stop and now I’m running into the issue and I can’t manage to get around it. EDIT: Oh, I forgot that, in the meantime, I had an issue with a dead container and I tried this, which solved this problem but might be at the root the de bad driver problem.

The only thing I found to solve the problem is rebooting my computer… ---

OK, I think I found a way to reproduce the issue. make run (or run-server) while mySQL/postgreSQL services are running. After that, even if you stop the services, make stop and make clean-docker, the issue will alway reproduce until a system reboot. ---

I’m getting the same issue. `make nuke` does not properly stop the databases. Can we mark this as unsolved? unless restarting is a viable solution in the meantime I’ll restrict myself to only using `make stop`. Another stop gap is to restart docker. So, -\> `make stop` -\> restart docker ![](https://us1.discourse-cdn.com/flex020/uploads/mattermost/original/2X/2/2474f3ad922cb5fb23ffceb6c5412745b6428411.png) -\> `make run` ---

Hi @morenoh149, I’ve edited the issue to be “unsolved”… Could you help to give me a suitable updated title for the issue or does it remain as is? Once we know the exact issue, it’ll be easier for someone to help with a solution. Thanks!
