Application Server
These instructions are for bootstrapping dolt as an application database server. They assume you are starting from scratch on a Linux machine without dolt installed or running.
Package manager support (
.deb and .rpm distributions) is coming soon, but for now this set of manual setup work is necessary.Install dolt. Run the following command:
sudo bash -c 'curl -L https://github.com/dolthub/dolt/releases/latest/download/install.sh | sudo bash'
This script puts the
dolt binary in /usr/local/bin, which is probably on your $PATH. If it isn't add it there or use use the absolute path of the dolt binary for next steps.Create a system account for the dolt user to run the server.
sudo useradd -r -m -d /var/lib/doltdb dolt
Before running the server, you need to give this user a name and email, which it will use to create its commits. Choose a dolt system account for your product or company.
$ cd /var/lib/doltdb
$ sudo -u dolt dolt config --global --add user.email [email protected]
$ sudo -u dolt dolt config --global --add user.name "Dolt Server Account"
You can override this user for future commits with the
--author flag, but this will be default author of every commit in the server.Before running the dolt server for the first time, you need to create a database. Choose a directory within
/var/lib/doltdb/databases where you want your dolt data to live. Name the directory the same as the name of your database.cd /var/lib/doltdb
sudo -u dolt mkdir -p databases/my_db
cd databases/my_db
sudo -u dolt dolt init
You should see output indicating that the database has been initialized:
Successfully initialized dolt data repository.
Assuming you want your dolt server to always be running when the machine is alive, you should configure it to run through the Linux service management tool,
systemctl. Some distributions of Linux do not support this tool; consult their documentation for configuration instructions.Write the server's config file in your home directory, then move it to where
systemctl needs it to live.cd ~
cat > doltdb.service <<EOF
[Unit]
Description=dolt SQL server
After=network.target
[Install]
WantedBy=multi-user.target
[Service]
User=dolt
Group=dolt
ExecStart=/usr/local/bin/dolt sql-server -u root
WorkingDirectory=/var/lib/doltdb/databases/my_db
KillSignal=SIGTERM
SendSIGKILL=no
EOF
sudo chown root:root doltdb.service
sudo chmod 644 doltdb.service
sudo mv doltdb.service /etc/systemd/system
Finally, start the server as a system daemon.
sudo systemctl daemon-reload
sudo systemctl enable doltdb.service
sudo systemctl start doltdb
The dolt sql server will now be running as a daemon. Test connecting to it with any SQL shell. Here we are using the mysql shell to connect.
mysql -h 127.0.0.1 -u root -p''
Note that by default, Dolt runs on the same port as MySQL (3306). If you have MySQL installed on the same host, choose a different port for the server with the
-P argument.With the above settings, dolt runs with a single user
root and an empty password. Dolt currently supports a single user and password. To change the name and password of the SQL user, provide a config file as described in the sql-server docs.Other configuration such as logging behavior, timeouts, etc. are available via this method as well.
These instructions should work for Debian, Ubuntu, Amazon Linux, and many other common distributions. If you find they don't work for yours and you would like your distribution documented, come chat with us on Discord or submit a PR to update the docs.
