无法启动 Zookeeper答案

【问题标题】：Not able to start zookeeper无法启动 Zookeeper
【发布时间】：2015-09-15 19:17:40
【问题描述】：

我正在尝试手动启动 zookeeper。我跑了

# source zkServer.sh start

它输出：

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

根据我在网上看到的，Zookeeper 和上面列出的QuorumPeerMain 是同一个过程。但是当我使用

检查它的状态时

source zkServer.sh status

它挂在：

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

所以我跑了

#source zkServer.sh status > templogs.txt

在上面运行会使终端在下面闪烁一会儿（我必须多次运行此命令才能在终端关闭之前读取终端上实际输出的内容）并关闭终端

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

写信给templogs.txt关注

Error contacting service. It is probably not running.

当我打开zookeeper.out 时，我可以看到这个输出：

是不是就像 zookeeper 卡在获取到 2181 端口的绑定一样？

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。

在另一台电脑上运行source zkServer.sh status，正确给出

Mode: standalone

但是在这台 PC 上，我几乎完蛋了。谁能帮帮我。

【问题讨论】：

source 是一个 shell 内置命令，用于将给定文件的内容加载（执行）到你当前的 shell 中，所以我建议你不要使用source 来运行zkServer.sh。相反，只需输入 ./zkServer.sh 或 ./bin/zkServer.sh。
@Mahesha999 如果您能够解决并记住它，请分享解决方案。
抱歉现在想不起来了

【解决方案1】：

你确认配置文件没问题吗？

尝试使用配置文件完整路径运行 Zookeeper

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

【解决方案2】：

PORT 绑定似乎有些问题

"绑定到端口0.0.0.0/0.0.0.0:2181"

应该通过在主机文件下面添加主机条目来解决问题

127.0.0.1 localhost

【讨论】：

【解决方案3】：

就我而言，我没有安装JAVA

所以它没有启动

请下载JDK和install 然后再试一次

【解决方案4】：

在我的例子中，zookeeper 3.7.0。只需要关闭tomcat服务器
