我正在尝试使用此文档在我的 macbook pro 上部署开发/测试复制集。
http://docs.mongodb.org/manual/tutorial/deploy-replica-set/
我启动了 3 个 mongod 实例，每个实例在端口 10001、10002、10003 我使用配置文件启动 mongod。配置文件如下：
rs0:
dbpath = /Users/Thomas/mongodb/data/rs0/
port = 10000
logpath = /Users/Thomas/mongodb/log/rs0.log
logappend = true
replSet = rs0
rs1:
dbpath = /Users/Thomas/mongodb/data/rs1/
port = 10001
logpath = /Users/Thomas/mongodb/log/rs1.log
logappend = true
replSet = rs0
rs2:
dbpath = /Users/Thomas/mongodb/data/rs2/
port = 10002
logpath = /Users/Thomas/mongodb/log/rs2.log
logappend = true
replSet = rs0
并使用以下命令启动：
mongod -f config/rs0.conf
mongod -f config/rs1.conf
mongod -f config/rs2.conf
然后我使用 mongo: mongo localhost:10001 连接到它，但是当我使用 rs.initiate() 命令初始化 repl 集时，它失败了。
> rs.initiate()
{
"startupStatus" : 4,
"info" : "rs0",
"errmsg" : "all members and seeds must be reachable to initiate set",
"ok" : 0
}
并通过 rs.status() 检查
> rs.status()
{
"startupStatus" : 4,
"errmsg" : "can't currently get local.system.replset config from self or any seed (EMPTYUNREACHABLE)",
"ok" : 0
}
日志显示这是一个 EMPTYUNREACHABLE 错误。怎么解决呢？
