如何在 Ubuntu 上停止 ZooKeeper？

Question

我已经按照此处的建议在 Ubuntu 14.04 (Trusty Tahr) 上安装了 zookeeperd ：

不幸的是，这个过程在某种程度上是不可停止的。我什至尝试过 kill -9

user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4008     1  8 01:07 ?        00:00:00 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

展示过程

user      4055  2823  0 01:07 pts/3    00:00:00 grep --color=auto zookeeper

杀了它

user@node1:/opt/zookeeper-3.4.6$ sudo kill -9 4008

查看：

user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4075     1 24 01:07 ?        00:00:00 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

尝试脚本

user@node1:/opt/zookeeper-3.4.6$ sudo /etc/init.d/zookeeper stop
user@node1:/opt/zookeeper-3.4.6$ ps -ef | grep zookeeper
zookeep+  4075     1 29 01:07 ?        00:00:04 /usr/bin/java -cp /etc/zookeeper/conf:/usr/share/java/jline.jar:/usr/share/java/log4j-1.2.jar:/usr/share/java/xercesImpl.jar:/usr/share/java/xmlParserAPIs.jar:/usr/share/java/netty.jar:/usr/share/java/slf4j-api.jar:/usr/share/java/slf4j-log4j12.jar:/usr/share/java/zookeeper.jar -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.local.only=false -Dzookeeper.log.dir=/var/log/zookeeper -Dzookeeper.root.logger=INFO,ROLLINGFILE org.apache.zookeeper.server.quorum.QuorumPeerMain /etc/zookeeper/conf/zoo.cfg

没有任何帮助。

我怎么能停止 ZooKeeper？

Answer 1

你可以试试：

sudo service zookeeper stop

停止该过程。如果它不起作用，您可以检查此链接：

Stop ZooKeeper. On the ZooKeeper host machine, execute the following command:

su - zookeeper -c "export ZOOCFGDIR=/etc/zookeeper/conf ; export ZOOCFG=zoo.cfg ;source /etc/zookeeper/conf/zookeeper-env.sh ; /usr/lib/zookeeper/bin/zkServer.sh stop" 

如果上述命令没有停止 Zookeeper 并且 kill -9 也无法停止，那么可能是僵尸进程。如果是这种情况，您可以查看此问答如何停止此类进程。
