Zookeeper数据目录清理 [英] Zookeeper data directory cleanup

问题描述

我正在运行3个节点的zookeeper集群来处理风暴和kafka.Zookeeper数据目录占用了系统中的所有空间.我不确定如何清理它，因为我不想完全删除数据因为我会丢失进程的状态.我在 zoo.cfg 中查看了 autopurge.purgeInterval ，但是它没有按预期工作.

我正在使用Zookeeper 3.4.6

如何删除旧数据而不影响新数据?

How can I delete the old data without affecting the new ones?

推荐答案

假定您在/opt/zookeeper-3.4.6 中安装了zookeeper，则以下内容将删除除最后10个快照以外的所有快照.

Assuming you have zookeeper installed in /opt/zookeeper-3.4.6, the following will delete all but the last 10 snapshots.

1. 停止zookeeper(/opt/zookeeper-3.4.6/bin/zkServer.sh stop )
2. cd/opt/zookeeper-3.4.6
3. ./zkCleanup.sh ../data/-n 10

在执行此操作之前，最好对整个/opt/zookeeper-3.4.6目录进行备份.

Probably wise to make a backup of the whole /opt/zookeeper-3.4.6 dir before doing this.
