Question

我最近安装了一个新的ZK节点w / Exhibitor，它开始很好。当我执行telnet localhost 2181然后运行stats以查看版本时，即使我安装了3.4.11，我也会在输出中看到3.4.5版本。我试图找到ZooKeeper读取版本号的位置，但它只是一个.jar和一些lib文件。你知道我在哪里可以获得真实的＆＃34;版本我应该在运行吗？谢谢！

这是我在执行telnet时看到的：

myserver:/tmp/zookeeper # telnet localhost 2181
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
stats
Zookeeper version: 3.4.5-1392090, built on 09/30/2012 17:52 GMT

正在运行的流程（ps aux | grep zookeeper）显示：

Answer 1

cat zookeeper-server.log | grep zookeeper.version

... INFO服务器环境：zookeeper.version = 3.5.7 -f0fdd52973d373ffd9c86b81d99842dc2c7f660e，建于格林尼治标准时间02/10/2020 11:30（org.apache.zookeeper.server.ZooKeeperServer） .....

假设您在本地主机上运行ZooKeeper，ZooKeeper支持四个字母命令：

$ echo "status" | nc  localhost 2181 | head -n 1
Zookeeper version: 3.4.9-3--1, built on Fri, 24 May 2019 08:57:53 +0100

使用一些bash魔术，您可以过滤出主要版本：

$ echo "status" | nc  localhost 2181 | head -n 1 | awk '{ print $3}' | cut -d "-" -f 1

检查源后，似乎有一个名为Info的界面给出了版本号。可以在这里看到：https://github.com/apache/zookeeper/blob/master/src/java/main/org/apache/zookeeper/Version.java

因此，版本文件在构建时完成。
