Question

我尝试使用ansible-mongodb-cluster脚本来创建mongodb群集。我已经编辑过主机，只有主要和从属。我使用molecule和vagrant来测试它。

这是我的分子.yml

ansible:
  playbook: 01_create_cluster.yml
  verbose: vvv
inventory: hosts
vagrant:
  platforms:
    - name: centos
      box: centos/7
  providers:
    - name: virtualbox
      type: virtualbox
      options:
        memory: 512
        cpus: 2
  instances:
    - name: mongo1
      ansible_groups:
        - mongo_servers
        - mongod_primary
        - mongod_slaves
      interfaces:
        - network_name: private_network
          type: static
          ip: 192.168.80.1
    - name: mongo2
      ansible_groups:
        - mongo_servers
        - mongod_primary
        - mongod_slaves
      interfaces:
        - network_name: private_network
          type: static
          ip: 192.168.80.2

这是hosts库存安全文件：

[mongo_servers]
mongo1 mongod_port=27017
mongo2 mongod_port=27017

[mongod_primary]
mongo1 mongod_port=27017

[mongod_slaves]
mongo2 mongod_port=27017

当创建主数据库并在其上激活复制后，奴隶尝试连接到主服务器时，问题就出现了：

"MongoDB shell version v3.4.4", 
        "connecting to: mongodb://mongo1:27017/", 
        "2017-05-25T15:38:51.399+0000 I NETWORK  [thread1] getaddrinfo(\"mongo1\") failed: Name or service not known", 
        "2017-05-25T15:38:51.400+0000 E QUERY    [thread1] Error: couldn't initialize connection to host mongo1, address is invalid :", 
        "connect@src/mongo/shell/mongo.js:237:13", 
        "@(connect):1:6"

它不知道mongo1主持人。

即使我添加/etc/hosts关系

192.168.80.1 mongo1

它告诉我Destination Net Unreachable

我如何解决并让每个VM＆＃34;看到＆＃34;网络中的其他人？

修改

ping进入超时并且telnet也是

EDIT2

这是traceroute

[vagrant@mongo2 ~]$ traceroute mongo1

我解决了将另外两种配置添加到molecule.yml：

interfaces:
        - network_name: private_network
          type: static
          ip: 192.168.80.1
          auto_config: true
      options:
        append_platform_to_hostname: no


auto_config: true

和

options:
            append_platform_to_hostname: no

现在，如果我ping其他虚拟机，他们会成功回复！
