於 2019年2月28日 (四) 04:21 的修訂
ZooKeeper是一套分散式的Key-Value系統。
安裝
在Ubuntu下可以直接安裝:
sudo apt install -y zookeeper
設定
每台機器的/etc/zookeeper/conf_production/myid
都需要不同,可以從1
到255
:
1
這邊要列出所有機器/etc/zookeeper/conf_production/zoo.cfg
:
tickTime=2000
dataDir=/var/lib/zookeeper/
clientPort=2181
initLimit=5
syncLimit=2
server.1=172.31.x:2888:3888
server.2=172.31.x:2888:3888
server.3=172.31.x:2888:3888
接下來是設定systemd的/lib/systemd/system/zookeeper.service
:
[Unit]
Description=ZooKeeper Service
Documentation=http://zookeeper.apache.org
Requires=network.target
After=network.target
[Service]
Type=forking
User=nobody
Group=nogroup
ExecStart=/usr/share/zookeeper/bin/zkServer.sh start /etc/zookeeper/conf/zookeeper.conf
ExecStop=/usr/share/zookeeper/bin/zkServer.sh stop /etc/zookeeper/conf/zookeeper.conf
ExecReload=/usr/share/zookeeper/bin/zkServer.sh restart /etc/zookeeper/conf/zookeeper.conf
WorkingDirectory=/var/lib/zookeeper
[Install]
WantedBy=default.target
然後連結:
sudo systemctl daemon-reload
sudo systemctl enable zookeeper
