Deploy a replica set
A three-member replica set
server info: scdbm06~08
mkdir -p /mongodb/data
mkdir -p /mongodb/log
上传文件到 /mongodb
2. On scdbm06
cd /mongodb
tar –zxvf mongodb-linux-x86_64-2.6.6.tgz
3. On scdbm07~8 copy 解压的mongodb文件
scp -r root@scdbm06:/mongodb /
4. On scdbm06~08 启动mongod
/mongodb/mongodb-linux-x86_64-2.6.6/bin/mongod --fork --port 27017 --dbpath /mongodb/data --logpath=/mongodb/log/mongodb.log --replSet repset --smallfiles --oplogSize 128 --httpinterface
5. On scdbm06 Connect a mongo shell to a replica set member.
/mongodb/mongodb-linux-x86_64-2.6.6/bin/mongo --port 27017
6. On scdbm06 Initiate the replica set.
Use rs.initiate() on the replica set member:
rs.initiate()
7. On scdbm06 Verify the initial replica set configuration.
Use rs.conf() to display the replica set configuration object:
rs.conf()
8. On scdbm06 Add the remaining members to the replica set.
Add the remaining members with the rs.add() method.
The following example adds two members:
rs.add("scdbm07")
rs.add("scdbm08")
9. On scdbm06 Check the status of the replica set.
Use the rs.status() operation:
rs.status()
--ps -aux | grep mongodb
上面的(6.7.8)可以使用下面的代替
use admin
config = { _id:"repset", members:[
{_id:0,host:"scdbm06:27017"},
{_id:1,host:"scdbm07:27017"},
{_id:2,host:"scdbm08:27017"}]
}
rs.initiate(config);
