Installing Mattermost on CentOS 7

[wirestyle22]

Hm. Interesting. I'd like to set this up on a test machine right now. Maybe I will tonight.

Why was postgres used? Nothing wrong with it of course, but not typically used on RHEL based stuff for the masses

both my preferred, so I didn't fight it, and the recommended one from the Mattermost project. They support MySQL, of course, but they push PostgreSQL as their preferred so I went with that.

Interesting that they chose it is all.

psql --host=127.0.0.1 --dbname=mattermost --username=mmuser --password

As a test:

psql --host=127.0.0.1 --dbname=mattermost --username=administrator --password

This is the user I created for these steps:

sudo -i -u postgres
psql
CREATE DATABASE mattermost;
CREATE USER mmuser WITH PASSWORD 'noonewilleverguess';
GRANT ALL PRIVILEGES ON DATABASE mattermost to mmuser;
\q
exit

Error:

[root@vultr ~]# psql --host=127.0.0.1 --dbname=mattermost --username=administrator --password
Password for user administrator:
psql: FATAL: Ident authentication failed for user "administrator"

Yes, widely supported but rarely the primary choice. It might be tied to Go for all that I know. Ruby, for example, as a culture leans to PostgreSQL not MySQL whereas PHP leans the other way. Don't know anything about the Go culture so just speculating.

Did you change the "peer" to "md5" in the config file?

Yes I did. I even went back, copy and pasted everything directly from the guide: mmuser noonewilleverguess etc and it still did the same thing.

Just to verify

Oddly the Docker container uses MySQL. I'm playing with it right now to learn both Mattermost and Docker.

That interesting. I need to play with Docker too.

@wirestyle22 I have the same problem

[aaronxiang]

@scottalanmiller I have the same problem. Confused

For those who were still having problems getting Mattermost running on CentOS 7, I was also having the same problems and couldn't get beyond the postgres install. I found another guide and with a few tweaks, I was able to get this running.

https://www.howtoforge.com/tutorial/install-mattermost-with-postgresql-and-nginx-on-centos7/

The change that was required from this guide was in the "Download and Extract Mattermost"

Instead of...
[root@mattermost ~]# wget -q "https://github.com/mattermost/platform/releases/download/v2.0.0/mattermost.tar.gz" -O mattermost.tar.gz

Use this...
wget https://releases.mattermost.com/3.3.0/mattermost-team-3.3.0-linux-amd64.tar.gz

Then in the next block, instead of...
tar -xvzf mattermost.tar.gz

Use this...
tar -xvzf mattermost-team-3.3.0-linux-amd64.tar.gz

After that, follow the guide to the letter and it will get you to this...
