zookeeper日志怎么查看（zookeeper查看日志方法）

zookeeper的事务日志通过zoo.cfg文件中的dataLogDir配置项配置，文件如下：

zookeeper提供了查看事务日志的工具类LogFormatter，运行：

java -classpath.:slf4j-api-1.6.1.jar:zookeeper-3.4.5.jarorg.apache.zookeeper.server.LogFormatter/export1/zookeeper/logs/version-2/log.1000003d2

注意：slf4j-api-1.6.1.jar和jar:zookeeper-3.4.5.jar可以通过find命令找到，如find / -name jar:zookeeper-3.4.5.jar

例如，我的环境得到的结果为

[root@node2 version-2]# java -classpath .:/data/hadoop/zookeeper-3.4.5/lib/slf4j-api-1.6.1.jar:/data/hadoop/zookeeper-3.4.6/zookeeper-3.4.6.jar org.apache.zookeeper.server.LogFormatter /data/hadoop/zookeeper/logs/version-2/log.f00000001

将看到格式化的日志内容类似：
