export PATH&＃61;$ZK_HOME/bin:$PATH

3.zookeper配置一个服务

1.添加java配置到zkEnv.sh

vim zkEnv.sh

 [Unit]
Description&＃61;zookeeper.service
After&＃61;network.target
ConditionPathExists&＃61;/usr/local/zookeeper-3.8.0/conf/zoo.cfg
[Service]
Type&＃61;forking

3.测试zookeeper.service

将服务加到系统中&＃xff1a;systemctl daemon-reload

启动&＃xff1a;systemctl start zookeeper

查看zookeeper的状态

systemctl status zookeeper
