1. Install mongo on the new member machine and start shard1

[root@ip-10-1-2-183 etc] # more shard1.conf

Logpath=/usr/local/mongodb/logs/mongo_shard1.log

Logappend=true # need logrotae scripts

Fork=true

Journal=true

Port=27019

# vvvvv = true

# diaglog = 3

Dbpath=/usr/local/mongodb/shard1

Bind_ip=10.1.2.183

ReplSet=shard1

Shardsvr=true

/ usr/local/mongodb/bin/mongod-f shard1.conf

two。 Add a new replica set member to the primary node

[root@ip-10-1-2-32 etc] # / usr/local/mongodb/bin/mongo 10.1.2.32 usr/local/mongodb/bin/mongo 27019

You can see that the new members have joined the replication set.

3.shard2 config plus members are the same (process is brief)

4. Check whether you have joined successfully.
