May I know how the permissions look like on your plugins directory? Please run the ls -lAh /opt/mattermost/plugins/ /opt/mattermost/prepackaged_plugins/ and provide the output here. For example, this is how it looks like on my end:
Based on the information you provided, it seems that you have set up the Mattermost server on a private server and are trying to access it without TLS (HTTP) using the URL _url:Port-Number. However, you are unable to access the server from your local machine. Here are a few tips to troubleshoot the issue:
If the connection is successful, it means your local machine can reach the server. If not, you may need to troubleshoot the network connectivity between your local machine and the private server.
5. Review Mattermost Logs: Check the Mattermost server logs (/opt/mattermost/logs) for any errors or warnings that might provide insights into the issue. Look for any log entries related to incoming connections or networking.
MariaDB is the sql server that we will use with Mattermost. Before we install it, we want to make sure that everything is up to date. Do so by running sudo apt update && sudo apt upgrade. Install MariaDB by running sudo apt install mariadb-server. Set it up by running sudo mysql_secure_installation. Make sure to set the root password. I recoment putting the root password in a password manager such as keepass.
Log into the server by running sudo mysql -u root -p using the root password you set. Create a use for mattermost by running create user 'mmuser'@'%' identified by 'mmuser-password'; changing mmuser-password with the password you want to set for the account. Again I recoment putting the password in a password manager. Create a database for mattermost by running create database mattermost;, and give the mmuser all permissions on the database by running grant all privileges on mattermost.* to 'mmuser'@'%';. While not required, I run flush privileges; afterwards to make sure the privileges get saved. Type exit to leave mysql.
Now we can install the server. First, create a folder to install mattermost to. sudo mkdir -p /opt/mattermost creates a folder in /opt to install it to. change to that directory using cd. Go to -memory/releases to get the latest build link by right clicking on the arm build and clicking the get link address option (I use Microsoft Edge (not legacy), it may be different in your browser. Download that file by pasting the url behind the wget command. As of writing, the command is wget -memory/releases/download/v5.32.1/mattermost-v5.32.1-linux-arm.tar.gz. Extract the file using tar. In my case, the command is sudo tar -xvf mattermost-v5.32.1-linux-arm.tar.gz As I like to organize my version, I will rename the extracted folder to the version name. mv mattermost mattermost-v5.32.1.
Next we need to create a user for Mattermost to run under as running as root is just a bad idea. Create a system user named mattermost by running sudo useradd --system --user-group --no-create-home mattermost and give it ownership of the mattermost install directory by running sudo chown -R mattermost:mattermost /opt/mattermost/. Edit the config for Mattermost to use your database by running sudo -u mattermost nano /opt/mattermost/mattermost-v5.32.1/config/config.json, being sure to modify the path as necessary. Go down to the SQL settings and set the driver to mysql and set DataSource to mmuser:mmuser-password@tcp(localhost:3306)/mattermost?charset=utf8mb4,utf8&readTimeout=30s&writeTimeout=30s. Exit nano using ctrl+x and press y to save and exit.
Systemd is the init system used on most Linux distros, and it is used by Raspberry Pi OS to create system services and start processes on boot. To create a service, create and open a new service file by running sudo -e /lib/systemd/system/mattermost.service and set it to the following, changing the paths as necessary.
Now we need to enable the service. Tell Systemd to (re)load the service file (sudo systemctl daemon-reload) and enable the config sudo systemctl enable mattermost.service). Either restart the pi or run sudo systemctl start mattermost.service to start the service.
Steps to reproduce
I am using a fedora37 workstation that I am trying to install mattermost on. I have created an postgresql account for mmuser so that mmost can log in and have followed the directions such that the config .json matches with the Driver name and data source. The only thing that I can think is that I am not putting in the right SiteUrl. Would I just use the fully qualified domain name of the computer or something else?
In a nutshell, the client reads the configured SiteUrl value of your Mattermost server and uses it for the connection, so if you change the SiteUrl in your config.jsonand restart the Mattermost server, this problem should be fixed.
Secondly, this feature creates obvious limitations. In the past, if an administrator wanted to set different SiteURLs for different groups of users, he/she could simply have them fill in their own SiteURLs on the client side. But with this feature, all users are forced to use the same SiteURL (that is, the unique SiteURL configured on the server side).
I understand that this feature may be for security and administrative convenience, but it does cause confusion. I think this feature should be introduced on the server side, not the client side. For example, an administrator can configure on the server whether to force clients to use SiteURL provided on the server. After all, new features should give more convenience than they give more limitation and confusion.
Naming conventions may be different for different network segments, and External vs. Internal, that all may need to get to the MatterMost server. Depending on routing and/or proxying if a single URL (DNS Name) is forced the ability to use different names depending on communication origin is lost.
In our case not only did I change SiteURL on the server (Thanks for that of course) but am having to do some quick split DNS work so that naming for MatterMost on our internal network will now match what it is accessed with from External through proxy.
The SiteUrl is also being used for several other things, like links in e-mails, OAuth integrations, etc., so while accessing the Mattermost server with basic functionality itself might work when using the IP address or alternative domain names, the best practice is to use just one SiteURL and make sure all your clients access the server using the same name:
Therefore, I would still recommend implementing this new feature on the server side instead of the desktop/mobile app side. I think one possible solution is to let the server decide which SiteURLs the client can access its service through. The new feature is great for alerting administrators and users about how to securely setup Mattermost, but I hope it puts the choice in the hands of the administrators of Mattermost services, rather than adding restrictions directly.
Please do not forget that the setup you used to have was unsupported by design and all implementation documents as well as setup guides always ask you to set the SiteURL and talk about this option to be a mandatory setting. The fact that it worked for you was maybe just because you did not make use of all the features Mattermost offers or were just lucky that you did not hit the limitations when the SiteURL is not set or does not match the URL people are accessing the server with (this also includes e-mails, permalink generation and all the other things I mentioned in my previous post).
I have a relatively fresh install of Omnibus Gitlab Community Edition 11.11.1 and recently activated Mattermost with SSL. Everything was working great until server rebooted. Attempting to reach the mattermost URL results in 502 Bad Gateway from nginx.
I wish to request the mattermost server as a snap. I see there already exist snaps for the mattermost client (mattermost-desktop), and the mattermost bridge (matterbridge). But how about the server itself?
however when i goto the website i couldn't get in

I am not sure how to map the nginx server to the mattermost server (mmserver) so that my mmserver can get the https instead of http
what I can only do is :8065 to log into my mattermost server
I don't know the exact config but you probably want to setup mmserver.kaidesign.uk in your nginx configuration (with ssl file paths configured and port set to standard https 443) and reverse proxy it to your port 8065 server (which can still run as http and probably doesn't need to be publicly accessible on that port).

I recently had to migrate an older installation of a Mattermost instance to a new server. Unfortunately, the old install method wasn't supported anymore and relied on a MySQL-database, which isn't officially supported anymore.
Your first step should be to make sure that your current instance is using the latest Mattermost version or at least version to which you are migrating. This is important because data exports may be incompatible if you try to import a newer export into an older server or the other way around.
You should now have the data export on your old Mattermost server. Depending on your infrastructure and if your old and new server have access to each other you will now need to somehow transfer the zip file to the new server.
In my case I used rsync to transfer the data to my laptop:
Depending on how big your data export file is you will need to make a few adjustments on the new instance as well as the server. For our team of around 15 people and an instance of around 18 months old this amounted to a backup size of around 5GB - including attachments, which is much too big for the default settings.
Next, edit the nginx config file for mattermost (located at /etc/nginx/conf.d/mattermost.conf) and configure the client_max_body_size to be bigger than your zip file. There are multiple locations where you have to overwrite this setting.
I used sed to replace all occurrences.
