# Zookeeper 常见问题 #

## 分布式集群启动 Invalid config, exiting abnormally ##

zookeeper 启动失败,查看启动日志 ：

2021-08-23 01:05:23,452 [myid:] - ERROR [main:QuorumPeerMain@89] - Invalid config, exiting abnormally

配置文件中有多余的括号，vim zoo.cfg, 然后在vim设置 `:set list` 以显示影藏字符

删除 server.x 行末的空白字符，然后启动 zookeeper

## Zookeeper error: Cannot open channel to X at election address ##

[Zookeeper error: Cannot open channel to X at election address][Zookeeper error_ Cannot open channel to X at election address]

## java.net.NoRouteToHostException: 没有到主机的路由 (Host unreachable) ##

机器的防火墙没有关闭
