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
#!/bin/bash
# Deploy mongodb,node-exporter,mongodb-exporter in suse 12 sp1
