Question

我正在尝试手动启动zookeeper。我跑

# source zkServer.sh start

输出：

JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED

当我运行#jps时，它会输出

15360 QuorumPeerMain
15412 Jps

从我在线阅读的内容来看，Zookeeper与上面列出的QuorumPeerMain处理过程相同。但是当我使用

检查其状态时

source zkServer.sh status

它挂在：

JMX enabled by default
Using config: /opt/zookeeper-3.4.6/bin/../conf/zoo.cfg

所以我跑

#source zkServer.sh status > templogs.txt

在上面运行会使终端闪烁到下面一会儿（我必须多次运行此命令才能读取终端关闭前实际输出的内容）并关闭终端

JMX enabled by default
Using config:
grep: No such file or directory
grep: No such file or directory

在

之后写templogs.txt

Error contacting service. It is probably not running.

当我打开zookeeper.out时，我可以看到此输出：

是不是像动物园管理员一样难以获得到2181端口的绑定？

但是当我运行lsof -i:2181 -s时，它会输出：

COMMAND   PID USER   FD   TYPE   DEVICE SIZE NODE NAME
java    15360 root  467u  IPv6 18340028       TCP *:eforward (LISTEN)

pid是QuorumPeerMain。

的pid

在另一台PC上运行source zkServer.sh status，正确提供

Mode: standalone

但是在这台电脑上，我几乎搞砸了。任何人都可以帮助我。

Answer 1

PORT绑定似乎有些问题

“绑定到端口0.0.0.0/0.0.0.0:2181”

并且应该通过在主机文件下面添加主机文件来解决问题

127.0.0.1 localhost

Answer 2

您是否确认配置文件正常？

尝试使用配置文件完整路径运行Zookeeper

示例：zkServer.sh start /etc/zookeeper/conf/zoo.cfg

Answer 3

就我而言，我不安装 JAVA

所以它没有启动

请下载JDK和install 然后再试一次

无法启动zookeeper
