Linux installation MongoDB

First, download

Linux:centos 7.3 64-bit

mongodb:3.6.4

Installation directory:/usr/local

cd/usr/localwget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64- Rhel62-3.6.4.tgz

Second, decompression

Unzip the installation package and rename it (easy to manage)

tar -zxvf mongodb-linux-x86_64-rhel62-3.6. 4 . tgz MV mongodb-linux-x86_64-rhel62-3.6. 4 MongoDB

Third, configure MongoDB

Need to configure three items, one is the Data folder (db, file name can be customized), one is the log folder (logs, file name can be customized), a configuration file (mongo.conf)

1. Data folder

mkdir DB

2. log Folder

mkdir Logs

3. Create a configuration file

# Where to write logging data.systemlog:  destination:file  logappend:true  Path:/usr/local/mongodb/logs/ Mongod.log #日志文件存放目录 # Where and how to store Data.storage:  dbPath:/usr/local/mongodb/db #数据文件存放目录  Journal:    enabled:true# How the process runsprocessmanagement:  fork:true  #以守护程序的方式启用, which runs in the background  Pidfilepath:/ Usr/local/mongodb/mongod.pid  # Location of pidfile# network interfacesnet:  port:27017 #端口  Bindip: 0.0.0.0  # Listen to local interface only, comment to Listen on all interfaces. Ports open to the outside

5. Start

MongoDB's Bin directory is executed under:

./mongod--config/usr/local/mongodb/mongod.conf

Iv. adding users

MongoDB installation After the default is not to verify the password, which in the production environment is absolutely not allowed to exist, we need to create users, and increase user authentication!

If a user is added to the admin database, the user will automatically get all the database permissions, i.e. the administrator account. If a user is added to a normal database, the user can only get the relevant permissions for that database, that is, the normal user.

Switch to the bin directory of MongoDB:

1. Add Administrator account

./MONGO> Useadmin>db.createuser ({User:"root",pwd: " Password ", roles:["root"]})

2. Enable MongoDB Authorization

After the mongod.conf, add:

Security:   // Enable authorization

3. Restart Effective

To close the MongoDB server:

./mongod-shutdown-dbpath=/usr/local/mongodb/db

After authorization, start the MONGODB server:

27017 --auth--fork

4. Authenticated Users

./MONGO>Use admin// will prompt user not to verify >db.auth ("root" ,"password")>show dbsadmin   0. 001GBconfig  0. 000GBlocal   0. 000GB

5, add ordinary users

 > Use LXCX //  CREATE DATABASE  > Db.createuser ({user: summer   ", pwd : "   , Roles:[{"  role  : "   ReadWrite  , "  db  : "   LXCX  }]}); //  

User: Username

PWD: Password

Roles: Specifies the role of the user, an empty array can be used to set the null role for the new user; In the Roles field, you can specify built-in roles and user-defined roles. Roles in role can be selected:

Built-in Roles (built-in role):    1. Database user role: Read, readWrite;    2. Database management roles: DbAdmin, Dbowner, Useradmin;    3. Cluster Management role: Clusteradmin, Clustermanager, Clustermonitor, Hostmanager;    4. Backup Restore role: backups, restore;    5. All database roles: Readanydatabase, Readwriteanydatabase, Useradminanydatabase, Dbadminanydatabase    6. Super User role: Root      //There are several roles here that indirectly or directly provide access to the system's Superuser (Dbowner, Useradmin, Useradminanydatabase)    7. Internal role: __system

READ: Allows the user to read the specified database ReadWrite: Allows the user to read and write to the specified database dbadmin: Allows the user to execute administrative functions in the specified database, such as index creation, deletion, View statistics or Access System.profileuseradmin: Allows the user to write to the System.users collection and can create, delete, and manage user clusteradmin in the specified database: Only available in the admin database. Gives the user administrative privileges on all shards and replica set related functions. Readanydatabase: Only available in the Admin database, giving the user read access to all databases Readwriteanydatabase: Only available in the admin database, Give users read and write access to all databases Useradminanydatabase: Available only in the admin database, giving the user useradmin permissions to all databases Dbadminanydatabase: Only available in the admin database, Gives the user dbadmin permissions for all databases. Root: Available only in the admin database. Super account, Super privilege
