liuxunorg commented on issue #3313: [ZEPPELIN-4004] add a systemd unit file to launch the Zeppelin daemon via systemd commands URL: https://github.com/apache/zeppelin/pull/3313#issuecomment-466470641 1. You need to determine whether the execution user is `root`, Because only `root` can copy files to `/etc/systemd/system`. ``` function check_user() { if [[ $(id -u) -ne 0 ]];then echo "This script must be run with a ROOT user!" exit fi } ``` 2. Need to determine whether the operating system is using `systemd` and `systemctl` for service startup (for example, debian 6 does not have `systemd`), Because there is no `systemd` and `systemctl`, executing the `systemctl` command will fail, so you need to give a prompt information. 3. Combine the `disable_zeppelin_systemd_service.sh` and `enable_zeppelin_systemd_service.sh` files into one file (for example, zeppelin_systemd_service.sh), `disable` and `enable` by executing parameters, Would it be better? Because not all operating systems use `systemd` for self-starting services. So maybe you can support the operating system with `systemd` installed first? This is just my suggestion, See if other people have any opinions? anyway, Thank you for your contribution! :-)
