linux system MongoDB single node installation tutorial

preface

MongoDB is a high-performance, open source, no model, based on the distributed file storage, document databases, believe no stranger to everyone, but here more introduced, this paper mainly introduced about mongo single node installation tutorial (linux), share out for your reference learning, few words said, below 1 look at the detailed installation process.

The installation package

Download address: (https: / / www. mongodb. com/download - center)

User permissions/directory

1. Create dbuser user

 groupadd dbgroup
 useradd dbuser -m -d /home/dbuser -g dbgroup

2. Deployment directory

mkdir -p /opt/local
chown -R dbuser:dbgroup /opt/local
cd /opt/local

3. Unzip the installation package

tar -xzvf mongodb-linux-x86_64-enterprise-suse11-3.2.7.tgz
mv mongodb-linux-x86_64-enterprise-suse11-3.2.7 mongodb
cd mongodb
mkdir conf data log

conf as profile directory data as data file directory log as log file directory

The configuration file

vim conf/mongo.conf

storage:
 dbPath: "/opt/local/mongodb/data/"
 engine: wiredTiger
# directoryPerDB: true
 journal:
 enabled: true
systemLog:
 destination: file
 path: "/opt/local/mongodb/log/mongodb.log"
 logAppend: true
# timeStampFormat: iso8601-utc
operationProfiling:
 slowOpThresholdMs: 10000
replication:
 oplogSizeMB: 700
processManagement:
 fork: true
 pidFilePath: "/opt/local/mongodb/mongod.pid"
net:
 port: 27017
 http:
 enabled: false
 unixDomainSocket:
 enabled : false

The startup port is 27017, and the http management interface is closed. slowOpThredsholdMs is the threshold for slow operation detection, which can be adjusted as needed;

Initialize the

1. Start mongod, which can be accessed anonymously by default

./bin/mongod -f conf/mongodb.conf

2. Connect to mongo

./bin/mongo --port 27017

3. Initialize the administrator

use admin
db.createUser({user:'admin',pwd:'admin@2016',roles:[{role:'clusterAdmin',db:'admin'},{role:'userAdminAnyDatabase',db:'admin'}]})

use appdb
db.createUser({user:'appuser',pwd:'appuser@2016',roles:[{role:'dbOwner',db:'appdb'}]})

4. Created administrator user and application account respectively, and then

Restart mongo to enable authentication

pkill mongod
./bin/mongod -f conf/mongodb.conf -auth

Connecting to mongo thereafter requires authentication

Common commands

Start the command

./bin/mongod -f conf/mongodb.conf

Stop command

kill -2 `cat mongod.pid`
rm mongod.pid

Test port

mkdir -p /opt/local
chown -R dbuser:dbgroup /opt/local
cd /opt/local

0

See the log

mkdir -p /opt/local
chown -R dbuser:dbgroup /opt/local
cd /opt/local

1

End connections

mkdir -p /opt/local
chown -R dbuser:dbgroup /opt/local
cd /opt/local

2

Monitoring commands

./bin/mongostat --port 27071 -u admin -p admin@2016 --authenticationDatabase=admin --discover -n 30 3
