创建副本集
｜
191
一旦启动它们，就应该有
3
个单独的
mongod
进程在运行。
通常来说，本章余下内容中介绍的原理适用于生产部署中使用的副本集，其
中每个
mongod
都有一个专用主机。不过，第
19
章会详细介绍与保护副本集
有关的一些其他细节问题，本章先提前在此处简要介绍一下这些内容。
10.3
网络注意事项
副本集中的每个成员都必须能够连接到其他成员（包括自身）。如果收到有关成员无法访
问到其他正在运行成员的错误，则可能需要更改网络配置以允许它们之间的连接。
已启动的进程可以轻松地在单独的服务器上运行。但是，在
MongoDB
3.6
中，
mongod
仅在
默认情况下绑定到
localhost
（
127.0.0.1
）
。为了使副本集中每个成员都可以与其他成员通信，
还必须绑定到其他成员可以访问到的
IP
地址
。如果在
IP
地址为
192.51.100.1
的网络接口的
服务器上运行
mongod
实例
，并且希望将其作为副本集的成员运行，同时每个成员都在不同
的服务器上，则可以指定命令行参数
--bind_ip
或在此实例的配置文件中使用
bind_ip
：
$ mongod --bind_ip localhost,192.51.100.1 --replSet mdbDefGuide \
--dbpath ~/data/rs1 --port 27017 --smallfiles --oplogSize 200
在这种情况下，无论是在
Linux
、
macOS
还是
Windows
系统中运行，都将进行类似的修改
以启动其他的
mongod
。
