如何全自动安装Mongo副本集

小编给大家分享一下如何全自动安装Mongo副本集，希望大家阅读完这篇文章之后都有所收获，下面让我们一起去探讨吧！

在opensuse12 sp1上使用shell脚本自动安装部署Mongodb副本集，集群一共三个虚拟机节点

Deploy Mongodb Replica Set

mongo# chmod +x deployinstance.sh initreplicaset.sh# 三个节点上分别运行该脚本mongo# ./deployinstance.sh# ip1 和ip2 是mongodb中作为secondary的节点ip,然后在Primary节点上运行该脚本mongo# ./initreplicaset.sh ip1 ip2

deployinstance.sh
