当zookeeper启动失败：Invalid config, exiting abnormally

章节目录

环境说明

  1. zookeepe镜像版本：wurstmeister/zookeeper latest 3f43f72cb283 3 years ago 510MB

问题说明

我有一次 zookeeper 容器启动过程中，不小心强制关机了，所以可能破坏了 zookeeper 某些数据，导致启动失败

zookeeper 启动报错日志

  1. ZooKeeper JMX enabled by default
  2. Using config: /opt/zookeeper-3.4.13/bin/../conf/zoo.cfg
  3. mkdir: cannot create directory '': No such file or directory
  4. log4j:WARN No appenders could be found for logger (org.apache.zookeeper.server.quorum.QuorumPeerConfig).
  5. log4j:WARN Please initialize the log4j system properly.
  6. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
  7. Invalid config, exiting abnormally

解决方案

zookeeper 容器名称是：

  1. kafka-docker_zookeeper_1

1. 查看该容器挂载目录

  1. docker inspect kafka-docker_zookeeper_1
  1. [{"Mounts":[{"Type":"volume","Name":"ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02","Source":"/var/lib/docker/volumes/ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02/_data","Destination":"/opt/zookeeper-3.4.13/conf","Driver":"local","Mode":"rw","RW":true,"Propagation":""},{"Type":"volume","Name":"9690de948c110633badd453f11e9bca3fb3692e88f54ae40f9e726ad0c64332a","Source":"/var/lib/docker/volumes/9690de948c110633badd453f11e9bca3fb3692e88f54ae40f9e726ad0c64332a/_data","Destination":"/opt/zookeeper-3.4.13/data","Driver":"local","Mode":"rw","RW":true,"Propagation":""}],}]

2. 查看该容器挂载目录的配置文件

进入容器挂载目录

  1. # 进入容器挂载目录cd /var/lib/docker/volumes/ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02/_data

目录文件如下所示：

  1. [root@centos _data]# ll
  2. 总用量 4
  3. -rw-r--r--. 1501ftp5356月  302018 configuration.xsl
  4. -rw-r--r--. 1501ftp012月 1215:07 log4j.properties
  5. -rw-r--r--. 1501ftp012月 1215:07 zoo.cfg

发现三个文件中，

  1. log4j.properties

和 

  1. zoo.cfg

两个文件大小都是 

  1. 0

，两个配置文件是空的，查看 

  1. zoo.cfg

内容，发现确实是空的，猜测 Zookeeper 启动失败正是因为配置文件的问题，需要补全。

3. 尝试查找旧的完整配置文件

zookeeper 以前有正常启动过的，都会在以下目录动态生成挂载目录，所以，在该目录下查找 

  1. zoo.cfg

文件，根据时间，找到以前生成的 

  1. zoo.cfg

配置文件

  1. find /var/lib/docker/volumes/ -name zoo.cfg
  1. [root@jiewli _data]# find /var/lib/docker/volumes/ -name zoo.cfg
  2. /var/lib/docker/volumes/ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02/_data/zoo.cfg

  4. /var/lib/docker/volumes/7e9b3a353466085395fd3a2a4bede7b974a0ae8101ee3d87f1e15c1c17d36a38/_data/zoo.cfg

找到了 4 个，找到其中日期为以前的：

  1. [root@jiewli _data]# cd /var/lib/docker/volumes/7e9b3a353466085395fd3a2a4bede7b974a0ae8101ee3d87f1e15c1c17d36a38/_data[root@jiewli _data]# ll

4. 用旧的完整配置文件覆盖疑似有问题的当前配置文件

三个文件，哪个有问题就覆盖哪个，我直接三个文件全部删掉，复制旧文件到当前挂载目录，如果没有旧文件，我已经将内容全部贴出来了，可以手动写入覆盖。

  1. rm-f /var/lib/docker/volumes/ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02/_data/*
  3. cp /var/lib/docker/volumes/64162e6eb0c30bc890fe07ac3acd60f8331131a5d8b5e55467d965e5573ee626/_data/* /var/lib/docker/volumes/ee425b5732918a15e1f3da9c9fb617d93b47cc0c67086c34005fa18e94f60e02/_data/

5. 重启容器

  1. docker restart kafka-docker_zookeeper_1

正常

思维扩展，类似问题排查

所有启动时报 

  1. Invalid config, exiting abnormally

错误的问题，都可以按照上面的步骤排查配置文件问题，这次是 

  1. zoo.cfg

，或许也有可能是别的配置文件出问题。但只要按照上面步骤，也算是比较高效的排查方式。
