Installing MongoDB v3.2 notes under Linux (CentOS)

1. Download MongoDB

The default is 64-bit, this is a bit awkward ...

64-bit system: https://www.mongodb.org/dl/linux/x86_64-debian81?_ga=2.15324022.1713724367.1498550277-1089294971.1498550277

32-bit Download list address: Https://www.mongodb.org/dl/linux

32-bit v3.2 version address http://downloads.mongodb.org/linux/mongodb-linux-i686-v3.2-latest.tgz?_ga= 2.114898759.1713724367.1498550277-1089294971.1498550277

2. Linux (32-bit system) direct

wget http://downloads.mongodb.org/linux/mongodb-linux-i686-v3.2-latest.tgz?_ga= 2.114898759.1713724367.1498550277-1089294971.1498550277

3. Unzip the Directory

TAR-XVF mongodb.tgz

4. Move the directory to/usr/local/mongodb

MV MongoDB (unzipped folder)/usr/local/mongodb

5. Configure Environment variables

Modify /etc/profile , add the following content

Export Mongodb_home=/usr/local/mongodb
Export path= $MONGODB _home/bin: $PATH

After saving, execute the following command:
Vim/etc/profile
Source/etc/profile

6. View MongoDB Version Information mongod -v

The installation is successful! Configure it below to start

7. Create a database directory

　　MongoDBYou need to build your own database folder.

Mkdir-p/data/mongodb
Mkdir-p/data/mongodb/log
Touch/data/mongodb/log/mongodb.log

Add a configuration file

Create a new mongodb.conf configuration file to boot from this configuration file.

Vim/etc/mongodb.conf

Configuration file Parameter Description:

MongoDB parameter Description:?--dbpath database path (data file)?--logpath log file path?--Master is specified as the primary machine?--slave specified as the IP address of the host machine?--source specified from the machine,?--Polog SIZE specifies that the log file size does not exceed 64M. Because the resync is very large and time-consuming, it is best to avoid resync by setting a large enough oplogsize (the default oplog size is 5% of the free disk size).?--Logappend Add?--port port number at the end of the log file?--Fork runs in the background?--only specifies which database is replicated?--Slavedelay refers to the time interval from replication detection?--Whether AUTH requires authentication permission to log on (user name and password) Note: Mong There are many parameters in the ODB configuration file, please refer to the official documentation for custom specific requirements.

Configuration file Contents:

Dbpath=/data/mongodb
Logpath=/data/mongodb/log/mongodb.log
Logappend=true
port=27017
Fork=true
# #auth = true # first close, create good user on start

To start a service from a configuration file:

Mongod--journal-f/etc/mongodb.conf (32-bit system requires parameter--journal)

To close a service through a configuration file:

Mongod--journal--shutdown-f/etc/mongodb.conf

8. Enter MongoDBBackground management Shell

Cd/usr/local/mongodb/bin
./mongo

Create data

Command Use test

Switched to DB test

Create a user, set permissions

Db.createuser (
    {
　　　　  User: "Test",
        PWD: "Test",
        Roles: [{role: ' ReadWrite ', DB: ' Test '}]
    }
)

Configuring firewalls

Adding 27017 ports to the firewall

Vi/etc/sysconfig/iptables
    -A input-m state--state new-m tcp-p TCP--dport 27017-j ACCEPT
/etc/init.d/iptables Reload
