Zookeeper - 三个节点,只有错误

Question

我有三个zookeeper节点.所有港口都是开放的.IP地址是正确的.下面是我的配置文件.由chef引导的所有节点都具有相同的安装和配置文件.

# The number of milliseconds of each tick
tickTime=3000
# The number of ticks that the initial
# synchronization phase can take
initLimit=10
# The number of ticks that can pass between
# sending a request and getting an acknowledgement
syncLimit=5
# the directory where the snapshot is stored.
dataDir=/var/lib/zookeeper
# Place the dataLogDir to a separate physical disc for better performance
# dataLogDir=/disk2/zookeeper

# the port at which the clients will connect
clientPort=2181

server.1=111.111.111:2888:3888
server.2=111.111.112:2888:3888
server.3=111.111.113:2888:3888

这是其中一个节点的错误.所以...我对如何得到错误感到困惑,因为配置相当香草.所有三个节点都在做同样的事情.

Answer 1

您需要创建一个名为myid的文件并将其放入zookeeper var目录中,每个服务器一个,包含一行只包含该计算机id的文本.所以服务器1的myid将包含文本"1"而没有别的.id在整体中必须是唯一的,并且应该具有1到255之间的值.

Answer 2

server.1=111.111.111:2888:3888
server.2=111.111.112:2888:3888
server.3=111.111.113:2888:3888

你的服务器和IP

然后在目录(dataDir=/var/lib/zookeeper)下的111.111.111和111.111.111.112和111.111.111.113服务器中值为1和3的每个节点上创建myid文件

如果将值“1”的 myid 文件置入值，如果创建的 myid 文件带有任何扩展名，则会出现数字格式异常和“无效的配置，异常退出”。

因此，只需创建没有任何扩展名的 myid 文件，并将整数值 1,2,3 放在相应的服务器中，无需双引号
