MongoDB's Master/slave mode

# # # MongoDB's master-slave configuration (without auth authentication)

# # # Notes:

-Synchronize the time before the server node

-Open the firewall must be allowed through the relevant port

-also set to enable SELinux

-Build double-click Trust mode is best

# # Master Config file

• -Added a Master = True This line can be

• -Multi-card machine bind_ip this line as much as possible to write a specific address (preferably the intranet address), because the slave is based on this synchronization
