Mongo quickly builds a replica set

first step:

Create 3 directories in the D:\MongoDB directory: conf (save the configuration folder), data (save the data folder), log (save the log folder)

Step 2:

Create rs1, rs2, and rs3 in the data folder respectively (save the data of the primary, secondary, and arbiter servers respectively)

third step:

Create rs1.conf, rs2.conf, rs3.conf configuration files in the conf folder

Contents of rs1:

1. dbpath=D:\MongoDB\data\rs1
2. logpath=D:\MongoDB\log\rs1.log
3. journal=true
4. port=40000
5. replSet=rs0

Contents of rs2:

1. dbpath=D:\MongoDB\data\rs2
2. logpath=D:\MongoDB\log\rs2.log
3. journal=true
4. port=40001
5. replSet=rs0

Contents of rs3:

1. dbpath=D:\MongoDB\data\rs3
2. logpath=D:\MongoDB\log\rs3.log
3. journal=true
4. port=40002
5. replSet=rs0

the fourth step:

Start the mongod service with conf

The following 3 commands are executed in 3 command lines respectively

1. mongod --config D:\MongoDB\conf\rs1.conf
2. mongod --config D:\MongoDB\conf\rs2.conf
3. mongod --config D:\MongoDB\conf\rs3.conf

the fifth step:

Login to 3 servers

The following 3 commands are executed in 3 command lines respectively

1. mongo --port 40000
2. mongo --port 40001
3. mongo --port 40002

Step 6:

Execute the following commands in sequence on the client corresponding to port 40000

1. rs.initiate()
2. rs.conf()
3. rs.add("DESKTOP-MNG19L3:40001")
4. rs.addArb("DESKTOP-MNG19L3:40002")
5. rs.status()

The result of running is as follows:

1. > rs.initiate()
2. {

4. "me":"DESKTOP-MNG19L3:40000",
