Debian Jessie搭建Mattermost

Debian Jessie搭建Mattermost

Websocket聊天,不支持xmpp

 

Install Debian Jessie (x64)


1. Set up 3 machines with Debian Jessie with 2GB of RAM or more. The servers will be used for the Load Balancer, Mattermost (this must be x64 to use pre-built binaries), and Database.
2. This can also be set up all on a single server for small teams:• I have a Mattermost instance running on a single Debian Jessie server with 1GB of ram and 30 GB SSD
• This has been working in production for ~20 users without issue.
• The only difference in the below instructions for this method is to do everything on the same server
• Make sure the system is up to date with the most recent security patches.• sudo apt-get update
• sudo apt-get upgrade

Set up Database Server


1. For the purposes of this guide we will assume this server has an IP address of 10.10.10.1
2. Install PostgreSQL 9.3+ (or MySQL 5.6+)• sudo apt-get install postgresql postgresql-contrib
• PostgreSQL created a user account called postgres. You will need to log into that account with:• sudo -i -u postgres
• You can get a PostgreSQL prompt by typing:• psql
• Create the Mattermost database by typing:• postgres=# CREATE DATABASE mattermost;
• Create the Mattermost user by typing:• postgres=# CREATE USER mmuser WITH PASSWORD 'mmuser_password';
• Grant the user access to the Mattermost database by typing:• postgres=# GRANT ALL PRIVILEGES ON DATABASE mattermost to mmuser;
• You can exit out of PostgreSQL by typing:• postgre=# \q
• You can exit the postgres account by typing:• exit
• Allow Postgres to listen on all assigned IP Addresses• sudo vi /etc/postgresql/9.3/main/postgresql.conf
• Uncomment ‘listen_addresses’ and change ‘localhost’ to ‘*’
• Alter pg_hba.conf to allow the mattermost server to talk to the postgres database• sudo vi /etc/postgresql/9.3/main/pg_hba.conf
• Add the following line to the ‘IPv4 local connections’
• host all all 10.10.10.2/32 md5
• Reload Postgres database• sudo /etc/init.d/postgresql reload
• Attempt to connect with the new created user to verify everything looks good• psql --host=10.10.10.1 --dbname=mattermost --username=mmuser --password
• mattermost=> \q

Set up Mattermost Server


1. For the purposes of this guide we will assume this server has an IP address of 10.10.10.1
2. Download the latest Mattermost Server by typing:
• wget https://github.com/mattermost/platform/releases/download/vX.X.X/mattermost.tar.gz
• Where vX.X.X is the latest Mattermost release version. For example, v2.0.0
• Install Mattermost under /opt
• Unzip the Mattermost Server by typing:
• tar -xvzf mattermost.tar.gz
• sudo mv mattermost /opt
• Create the storage directory for files. We assume you will have attached a large drive for storage of images and files. For this setup we will assume the directory is located at /opt/mattermost/data.
• Create the directory by typing:
• sudo mkdir -p /opt/mattermost/data
• Create a system user and group called mattermost that will run this service
• sudo useradd -r mattermost -U
• Set the mattermost account as the directory owner by typing:
• sudo chown -R mattermost:mattermost /opt/mattermost
• sudo chmod -R g+w /opt/mattermost
• Add yourself to the mattermost group to ensure you can edit these files:
• sudo usermod -aG mattermost USERNAME
• Configure Mattermost Server by editing the config.json file at /opt/mattermost/config
• cd /opt/mattermost/config
• Edit the file by typing:
• vi config.json
• replace DriverName": "mysql" with DriverName": "postgres"
• replace "DataSource": "mmuser:[email protected](dockerhost:3306)/mattermost_test?charset=utf8mb4,utf8"with "DataSource": "postgres://mmuser:[email protected]:5432/mattermost?sslmode=disable&connect_timeout=10"• Assuming a default IP address of 10.10.10.1
• Optionally you may continue to edit configuration settings in config.json or use the System Console described in a later section to finish the configuration.
• Test the Mattermost Server
• cd /opt/mattermost/bin
• Run the Mattermost Server by typing:
• ./platform
• You should see a console log like Server is listening on :8065 letting you know the service is running.
• Stop the server for now by typing ctrl-c
• Setup Mattermost to use the systemd init daemon which handles supervision of the Mattermost process
• sudo touch /etc/init.d/mattermost
• sudo vi /etc/init.d/mattermost
• Copy the following lines into /etc/init.d/mattermost

• Make sure that /etc/init.d/mattermost is executable
• sudo chmod +x /etc/init.d/mattermost
• On reboot, systemd will generate a unit file from the headers in this init script and install it in/run/systemd/generator.late/
Note: This setup can also be done using a systemd unit, usable for non-Debian systems, such as Arch Linux. The unit file is as follows:
# cat /etc/systemd/system/mattermost.service


[Unit]

# systemctl start mattermost
# systemctl enable mattermost

Set up Nginx Server


1. For the purposes of this guide we will assume this server has an IP address of 10.10.10.3
2. We use Nginx for proxying request to the Mattermost Server. The main benefits are:
• SSL termination
• http to https redirect
• Port mapping :80 to :8065
• Standard request logs
• Install Nginx on Debian with
• sudo apt-get install nginx
• Verify Nginx is running
• curl http://10.10.10.3
• You should see a Welcome to nginx! page
• You can manage Nginx with the following commands
• sudo service nginx stop
• sudo service nginx start
• sudo service nginx restart
• Map a FQDN (fully qualified domain name) like mattermost.example.com to point to the Nginx server.
• Configure Nginx to proxy connections from the internet to the Mattermost Server
• Create a configuration for Mattermost
• sudo touch /etc/nginx/sites-available/mattermost
• Below is a sample configuration with the minimum settings required to configure Mattermost


server {
server_name mattermost.example.com;
location / {
client_max_body_size 50M;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Frame-Options SAMEORIGIN;
proxy_pass http://10.10.10.2:8065;
}
}


• Remove the existing file with
• sudo rm /etc/nginx/sites-enabled/default
• Link the mattermost config by typing:
• sudo ln -s /etc/nginx/sites-available/mattermost /etc/nginx/sites-enabled/mattermost
• Restart Nginx by typing:
• sudo service nginx restart
• Verify you can see Mattermost thru the proxy by typing:
• curl http://localhost
• You should see a page titles Mattermost - Signup

Set up Nginx with SSL (Recommended)


1. You can use a free and an open certificate security like let’s encrypt, this is how to proceed
• sudo apt-get install git
• git clone https://github.com/letsencrypt/letsencrypt
• cd letsencrypt
• Be sure that the port 80 is not use by stopping nginx
• sudo service nginx stop
• netstat -na | grep ':80.*LISTEN'
• ./letsencrypt-auto certonly --standalone
• This command will download packages and run the instance, after that you will have to give your domain name
• You can find your certificate in /etc/letsencrypt/live
• Modify the file at /etc/nginx/sites-available/mattermost and add the following lines:


server {
listen 80;
server_name mattermost.example.com;
return 301 https://$server_name$request_uri;
}
server {
listen 443 ssl;
server_name mattermost.example.com;
ssl on;
ssl_certificate /etc/letsencrypt/live/yourdomainname/fullchain.pem;
ssl_certificate_key /etc/letsencrypt/live/yourdomainname/privkey.pem;
ssl_session_timeout 5m;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';
ssl_prefer_server_ciphers on;
ssl_session_cache shared:SSL:10m;
location / {
gzip off;
proxy_set_header X-Forwarded-Ssl on;
client_max_body_size 50M;
proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection "upgrade";
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
proxy_set_header X-Frame-Options SAMEORIGIN;
proxy_pass http://10.10.10.2:8065;
}
}


• Be sure to restart nginx
• sudo service nginx start
• Add the following line to cron so the cert will renew every month
• crontab -e
• @monthly /home/YOURUSERNAME/letsencrypt/letsencrypt-auto certonly --reinstall -d yourdomainname&& sudo service nginx reload

Finish Mattermost Server setup


1. Navigate to https://mattermost.example.com and create a team and user.
2. The first user in the system is automatically granted the system_admin role, which gives you access to the System Console.
3. From the town-square channel click the dropdown and choose the System Console option
4. Update Email Settings. We recommend using an email sending service. The example below assumes AmazonSES.• Set Send Email Notifications to true
• Set Require Email Verification to true
• Set Feedback Name to No-Reply
• Set Feedback Email to [email protected]
• Set SMTP Username to AFIADTOVDKDLGERR
• Set SMTP Password to DFKJoiweklsjdflkjOIGHLSDFJewiskdjf
• Set SMTP Server to email-smtp.us-east-1.amazonaws.com
• Set SMTP Port to 465
• Set Connection Security to TLS
• Save the Settings
• Update File Settings• Change Local Directory Location from ./data/ to /mattermost/data
• Update Log Settings.• Set Log to The Console to false
• Update Rate Limit Settings.• Set Vary By Remote Address to false
• Set Vary By HTTP Header to X-Real-IP
• Feel free to modify other settings.
• Restart the Mattermost Service by typing:• sudo restart mattermost
