MongoDB 3.2.7 for rhel6.4 副本集-分片集群部署

原创 NoSQL 作者:清风艾艾 时间:2016-11-15 15:08:56 0 删除 编辑
    今天,一同事反映,他安装部署mongodb副本集--分片集群,初始化分片时遇到问题:初始化分片必须使用主机名(也就是必须有相当于DNS服务的解析),这样以来,mongo副本集--分片集群就
会出现DNS服务器单点故障问题。为了验证这一问题,我单独使用ip部署mongo 3.2.7 for rhel 6.4 副本集--分片集群,验证结果是:副本集及分片初始化时使用IP,则同时均使用IP方式,使用host或
DNS解析,则副本集及分片初始化时均使用主机名或域名解析方式,可成功部署mongo 3.2.7 for rhel 6.4 副本集--分片集群。另外,个人观点:建议使用DNS或host域名解析,因为主机名可以不改变,
而主机的IP地址的改变可能性是很大的。
   mongo 3.2.7 for rhel 6.4 副本集--分片集群的部署过程如下:
   首先,确保rhel 6.4环境能支持3.2.7的安装部署,mongodb3.2.7单实例安装过程及可能遇到的问题可参考:
   MongoDB 3.2 for RHEL6.4 installation(地址:

到此,验证操作已经完毕,总结:副本集--分片集群部署过程中,可以只使用IP地址,但是需要注意的是副本集及分片配置时,如果使用IP则均使用IP地址。
附副本集--分片集群部署完成后,3个节点的mong0进程:
