This article mainly introduces how to deploy distributed database MongoDB under Linux. It is very detailed and has certain reference value. Friends who are interested must finish reading it.

MongoDB is a product between relational database and non-relational database, which is the most functional and most like relational database in non-relational database. The data structure he supports is very loose, which is similar to json's bjson format, so it can store more complex data types. The most important feature of Mongo is that the query language it supports is very powerful, and its syntax is somewhat similar to the object-oriented query language. It can almost achieve most of the functions similar to the single table query of relational database, and also supports the establishment of data indexing.

I. mongodb installation and configuration

1. Create a tools directory to store the installation package

Cd / usr/localmkdir-p toolscd tools

2. Download the mongodb package (other versions please download by yourself)

Wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-rhel70-3.2.4.tgz

3. Extract and copy mongodb to directory / usr/local/mongodb

Tar-zxvf mongodb-linux-x86_64-rhel70-3.2.4.tgz cp-r mongodb-linux-x86_64-rhel70-3.2.4 / usr/local/mongodb

4. System profile configuration

Vi / etc/profile export MONGODB_HOME=/usr/local/mongodb export PATH=$PATH:$MONGODB_HOME/bin

Mongodb system configuration

After saving, restart the system configuration

Source / etc/profile

5. Mongodb startup configuration

Cd / usr/local/mongodb/bin mkdir datacd datamkdir dbcd.. mkdir logscd logstouch mongodb.logcd.. vi mongodb.conf dbpath = / usr/local/mongodb/data/db # data file storage directory logpath = / usr/local/mongodb/logs/mongodb.log # log file storage directory port = 27017 # port fork = true # enabled as a daemon, that is, running nohttpinterface = true in the background

If the startup configuration is saved and exited, the mongodb.conf file exists in the bin directory.

II. Mongodb testing

1. Start the mongod database service

. / mongod-f mongodb.conf

2. Enter the mongodb database

. / Mongo III. Mongodb starts up

1. Set the mongodb.service startup service

Cd / lib/systemd/system vi mongodb.service [Unit] Description=mongodbAfter=network.target remote-fs.target nss-lookup.target [Service] Type=forkingExecStart=/usr/local/mongodb/bin/mongod-- config / usr/local/mongodb/bin/mongodb.conf ExecReload=/bin/kill-s HUP $MAINPID ExecStop=/usr/local/mongodb/bin/mongod-- shutdown-- config / usr/local/mongodb/bin/mongodb.conf PrivateTmp=true [Install] WantedBy=multi-user.target

2. Set mongodb.service permissions

Chmod 754 mongodb.service

3. System mongodb.service operation command

# start Service systemctl start mongodb.service # close Service systemctl stop mongodb.service # Boot start systemctl enable mongodb.service
