utils/morty.sh

further reading

To simplify installation and maintenance of a morty instance you can use the script git://utils/morty.sh. In most cases you will install morty simply by running the command:

sudo -H ./utils/morty.sh install all

The script adds a ${SERVICE_USER} (default:morty) and installs morty into this user account:

  1. Create a separated user account (morty).

  2. Download and install Go binary in user’s $HOME (~morty).

  3. Install morty with the package management from Go (go get -v -u github.com/asciimoo/morty)

  4. Setup a systemd service unit [ref] (/lib/systemd/system/morty.service).

Hint

To add morty to your searx instance read chapter How to setup result proxy.

Create user

$ sudo -H useradd --shell /bin/bash --system \
    --home-dir "/usr/local/morty" \
    --comment "Privacy-respecting metasearch engine" morty

$ sudo -H mkdir "/usr/local/morty"
$ sudo -H chown -R "morty:morty" "/usr/local/morty"

Install go

$ cat > "/usr/local/morty/.go_env" <<EOF
export GOPATH=/usr/local/morty/go-apps
export PATH=$PATH:/usr/local/morty/local/go/bin:$GOPATH/bin
EOF
$ sudo -i -u "morty"
(morty) $ echo 'source /usr/local/morty/.go_env' >> ~/.profile
(morty) $ mkdir /usr/local/morty/local
(morty) $ wget --progress=bar -O "go1.13.5.linux-amd64.tar.gz" \
            "https://dl.google.com/go/go1.13.5.linux-amd64.tar.gz"
(morty) $ tar -C /usr/local/morty/local -xzf "go1.13.5.linux-amd64.tar.gz"
(morty) $ which go
/usr/local/morty/local/go/bin/go
