Installing MongoDB on the CENTOS6

Heat up your hands for the next job.

Read a book before, understand, but it seems that three or four years, and forget. ：（

Reference URL:

Http://www.centoscn.com/image-text/install/2014/1124/4171.html

Environment:

System hardware: VMware vsphere (cpu:2*4 core, memory 2G)

System version: centos-6.5-x86_64

CentOS Compilation installs MongoDB 2.6 system preferably 64-bit, in order to better play MongoDB performance

Installation steps:

0. System Environment

[Email protected] ~]# cat/etc/redhat-release

CentOS Release 6.5 (Final)

[Email protected] ~]# uname-a

Linux CentOS 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 03:15:09 UTC x86_64 x86_64 x86_64 gnu/linux

[email protected] ~]# Yum install vim wget-y

1. Download the source file (binary compiled version)

[Email protected] ~]# mkdir-p/DATA/SRC

[Email protected] ~]# CD/DATA/SRC

[Email protected] ~]# wget http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.1.tgz

[Email protected] ~]# TAR-ZVXF mongodb-linux-x86_64-2.6.1.tgz

[Email protected] ~]# MV mongodb-linux-x86_64-2.6.1/opt/mongodb/

2. Configure the PATH environment variable to ensure that the MongoDB Bin directory is contained in the PATH environment variable.

2.1 Configuring Path

[Email protected] ~]# Vim/etc/profile

Add the following content:

#set for MongoDB
Export Mongodb_home=/opt/mongodb
Export path= $MONGODB _home/bin: $PATH

Save exit

2.1 View Current Path

[Email protected] ~]# echo $PATH

2.2 Let the environment variable take effect:

[Email protected] ~]# Source/etc/profile

[Email protected] ~]# echo $PATH

　　

3. Verify that the environment variable is in effect

[Email protected] ~]# mongod-version

4. Create a directory for storing data and logs:

4.1 Creating a Directory

[Email protected] ~]# mkdir-p/data/mongodb/journal

[Email protected] ~]# mkdir-p/data/mongodb/log

4.2 Creating a log file

[Email protected] ~]# Touch/data/mongodb/log/mongodb.log

4.3 Setting up the configuration file

[Email protected] ~]# vim/etc/mongodb.conf

Enter the following to save and rewind
Dbpath=/data/mongodb
Logpath=/data/mongodb/log/mongodb.log
Logappend=true
port=27017
Fork=true
Noauth=true
Nojournal = True
Smallfiles = True
Noprealloc = True

5. Add MongoDB users and set permissions

5.1 Adding users

[Email protected] ~]# useradd mongodb-m-s/sbin/nologin

5.2 Setting Directory Permissions

[[Email protected] ~] #chown-R Mongodb.mongodb/data/mongodb
　　

6. Restart, start the service

6.1 Restart
[Email protected] ~]# Shutdown-r now

6.2 After restarting, run the Mongod service
[Email protected] ~]# mongod-f/etc/mongodb.conf

7. Test whether the service is normal

7.1 Open another terminal and enter the admin background as an administrator

[[Email protected] ~] #mongo Admin

>show DBS;

>db.test.find ();

>exit

8. Add the Mongod service to the boot start service

8.1 Writing Service files

[Email protected] ~]# Vim/etc/init.d/mongod

Enter the following and save the exit (see code later)

8.2 Set to start the service

[Email protected] ~]# chkconfig--add Mongod

[Email protected] ~]# chkconfig--level 345 mongod on

[Email protected] ~]# chmod +x/etc/init.d/mongod

8.3 Testing
[[Email protected] ~] #service mongod Start

[[Email protected] ~] #service mongod Status

　　

9. Reboot, and test

[[Email protected] ~] #shutdown-R now

[[Email protected] ~] #service mongod Status

[[Email protected] ~] #mongo Admin

>show DBS;

>db.test.find ();

>exit

**********************************************
MongoDB's parameter description:
--dbpath database path (data file)
--logpath log file path
--master designated as the main machine
--slave specified as Slave machine
--source Specify the IP address of the host machine
--POLOGSIZE specifies that the log file size does not exceed 64M. Because 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 log file End add
--port Enable port numbers
--fork running in the background
--ONLY specifies which database to replicate only
--slavedelay refers to the time interval from which replication is detected
--auth If you need to verify permissions login (username and password)
