Konfigurasi Apache ZooKeeper Sebagai Service Pada Ubuntu 18.04

Pindahkan folder ZooKeeper ke dalam /opt/
sudo cp -R zookeeper_dir /opt/

Buat symbolic link ke direktori tersebut
sudo ln -s /opt/zookeeper_dir /opt/zookeeper

Buat file zookeeper.service di systemd
sudo nano /etc/systemd/system/zookeeper.service

Masukkan konten zookeeper.sevice berikut, sesuaikan jika perlu

[Unit]
Description=Zookeeper Daemon
Documentation=http://zookeeper.apache.org
Requires=network.target
After=network.target

[Service]
Type=forking
WorkingDirectory=/opt/zookeeper
User=zookeeperone

WantedBy=default.target

Pada kasus saya, tricky part ada di User dan Group, dimana saya harus memasukkan user yang digunakan pada waktu instalasi zookeeper, dalam hal ini zookeeperone.

Update .bashrc
source ~/.bashrc

Untuk mengaktifkan service
sudo systemctl enable zookeeper

Command lain terkait service zookeeper tersebut
systemctl start zookeeper
service zookeeper start
systemctl stop zookeeper
service zookeeper stop
systemctl reload zookeeper
service zookeeper reload
