# Manual Installation !!! info "Requirements on your server" - Node.js 12 or higher - Database (PostgreSQL, MySQL, MariaDB, SQLite) The database must use charset `utf8`. This is typically the default in PostgreSQL and SQLite. In MySQL and MariaDB UTF-8 might need to be set with `alter database character set utf8 collate utf8_bin;` Be aware of older MySQL and MariaDB versions which sometimes use shorter representations of UTF-8 than 4 bytes. This can break if symbols with more bytes are used. You can use `alter database character set utf8mb4 COLLATE utf8mb4_unicode_ci` to be on the safe side. - NPM (and its dependencies, [node-gyp](https://github.com/nodejs/node-gyp#installation)) - [Yarn Classic](https://classic.yarnpkg.com) 1.22 or higher (Yarn 2 is currently not supported) - Bash (for the setup script) - For **building** the HedgeDoc frontend you need a machine with at least **2 GB** RAM. - Starting with release 1.7 the release tarball includes the prebuilt frontend, so building it yourself is not necessary. 1. Check if you meet the [requirements at the top of this document](#manual-installation). 2. Download the [latest release](https://hedgedoc.org/latest-release/) and extract it. Alternatively, you can use Git to clone the repository and checkout a release, e.g. with `git clone -b 1.8.2 https://github.com/hedgedoc/hedgedoc.git`. 3. Enter the directory and execute `bin/setup`, which will install the dependencies and create example configs. 4. Configure HedgeDoc: To get started, you can use this minimal `config.json`: ```json { "production": { "db": { "dialect": "sqlite", "storage": "./db.hedgedoc.sqlite" }, "urlAddPort": true, "domain": "localhost" } } ``` It's also possible to use environment variables. For details, have a look at [the configuration documentation](../configuration.md). 5. *:octicons-light-bulb-16: If you use the release tarball for 1.7.0 or newer, this step can be skipped.* Build the frontend bundle by running `yarn install` and then `yarn build`. The extra `yarn install` is necessary as `bin/setup` does not install the build dependencies. 6. It is recommended to start your server manually once: ```shell NODE_ENV=production yarn start ``` This way it's easier to see warnings or errors that might occur. You can leave out `NODE_ENV=production` for development. 7. If you use the example config, HedgeDoc should now be available at [http://127.0.0.1:3000](http://127.0.0.1:3000). 8. Run the server as you like (node, forever, pm2, systemd, Init-Scripts). See [below](#systemd-unit-example) for an example using systemd. ## Upgrading !!! warning Before you upgrade, **always read the release notes**. You can find them on our [releases page](https://hedgedoc.org/releases/). If you want to upgrade HedgeDoc from an older version, follow these steps: 1. Check if you still meet the [requirements at the top of this document](#requirements-on-your-server). 2. Ensure you read the [release notes](https://hedgedoc.org/releases/) of all versions between your current version and the latest release. 2. Fully stop your old HedgeDoc server. 3. [Download](https://hedgedoc.org/latest-release/) the new release and extract it over the old directory. If you use Git, you can check out the new tag with e.g. `git fetch origin && git checkout 1.8.2` 5. Run `bin/setup`. This will take care of installing dependencies. It is safe to run on an existing installation. 6. *:octicons-light-bulb-16: If you used the release tarball for 1.7.0 or newer, this step can be skipped.* Build the frontend bundle by running `yarn install` and `yarn build`. The extra `yarn install` is necessary as `bin/setup` does not install the build dependencies. 7. It is recommended to start your server manually once: ```shell NODE_ENV=production yarn start ``` This way it's easier to see warnings or errors that might occur. 8. You can now restart the HedgeDoc server! ## Systemd Unit Example Using the unit file below, you can run HedgeDoc as a systemd service. !!! warning - In this example, you must configure HedgeDoc using the `config.json` file and the `production` key. - Make sure the user and group `hedgedoc` exists and has appropriate permissions in the directory you installed HedgeDoc in or change the `User` and `Group` settings in the unit file. - Make sure `WorkingDirectory` points to the directory you installed HedgeDoc in. - Make sure `ReadWritePaths` contains all directories HedgeDoc might write to. This may include the `public/uploads` folder if you configured local storage. If you use SQLite, you must also include the directory where the database file is saved. **Do not save the SQLite file in the root directory of the HedgeDoc installation**, but create a subfolder like `db`! - If you use an external database like PostgreSQL or MariaDB, make sure to add a corresponding `After` statement. ```ini [Unit] Description=HedgeDoc - The best platform to write and share markdown.
