MongoDB Basics (iv) Red Hat Enterprise 6.4 x64 Installation MONGDB 3.0 and configuration

Mongodb-org
The package is a metadata package, the following 4 package packages will be installed automatically when installed

Mongodb-org-server
The package contains the Mongod daemon, the associated configuration, and

the initial script Mongodb-org-mongos
the package contains the MONGOs daemon

Mongodb-org-shell
The package contains the MONGO Shell
 
mongodb-org-tools
The package contains the following MongoDB tools:
mongoimport bsondump, Mongodump,mongoexport, Mongofiles, Mongooplog, Mongoperf, Mongorestore, Mongostat, Andmongotop.

1. Create a Yum source Repository file:

Vi/etc/yum.repos.d/mongodb-org-3.0.repo

[mongodb-org-3.0]
Name=mongodb Repository
baseurl=http://repo.mongodb.org/yum/redhat/6/mongodb-org/3.0/x86_64/
Gpgcheck =0
enabled=1

2. Install MongoDB packages and related tools:

Yum Install-y mongodb-org

If you install the specified version of MongoDB, you should independently specify the version number for each component package and appended to the package name, such as: sudo yum install-y mongodb-org-3.0.2 mongodb-org-server-3.0.2 mongodb-org-shell-3.0.2 mongodb-org-mongos-3.0.2 mongodb-org-tools-3.0.2

You can also define any available MongoDB version, and Yum will automatically update the MONGODB package when there is an updated version. To prevent inadvertent updates, you can use the Exclude directive in/etc/yum.conf, such as:
Exclude=mongodb-org,mongodb-org-server,mongodb-org-shell,mongodb-org-mongos,mongodb-org-tools

3. Related configuration:

If the firewall is turned on, SELinux must be configured to allow MongoDB to run on the Red Hat system or CentOS Linux.
an administrator should set the following 3 options:

1. Allow port 27017 access (without first download tool semanage):
yum-y install Policycoreutils-python
semanage port-a-t mongod_port_t-p TCP 27017


2. In profile/etc/selinux/config set SELinux mode to permissive:
vi/etc/selinux/config

selinux=enforcing 
instead
Selinux=permissive


3. Completely disable SELINUX:
selinux=disabled

The default data file path for MongoDB instance storage is/var/lib/mongo, and the storage log file path is/var/log/mongodb and runs with the Mongod account. You can also configure the directory of data files and log files in the file/etc/mongod.conf.

Vi/etc/mongod.conf

4. Running MongoDB

Set up MongoDB with system self-boot:
chkconfig mongod on


enable MongoDB services: Service
mongod start


Verify that MongoDB started successfully: (see if the log has information waiting to be connected)
tail-5/var/log/mongodb/mongod.log

[Initandlisten] Waiting for connections On Port <port>

You also see that the data has been generated:

Enter MONGO directly on the command line to enter the database:

at this point, complete. ~
