Prerequisites:
1. Check whether mongodb has been installed
[Root @ ~] # Rpm-qa | grep mongodb
[Root @ vstar ~] # Service mongodb status
2. Create a user, install the required directory, and authorize
[Root @ ~] # Groupadd mongodb
[Root @ ~] # Useradd-g mongodb-s/sbin/nologin-M mongodb
[Root @ data] # mkdir-p/data/mongodb
[Root @ data] # chown-R mongodb: mongodb/data/mongodb
[Root @ data] # mkdir-p/var/log/mongodb
[Root @ data] # chown-R mongodb: mongodb/var/log/mongodb
Installation:
[Root @ ~] # Cd/data/
[Root @ data] # tar-zxvf mongodb-linux-x86_64-2.6.5.gz
[Root @ data] # mv mongodb-linux-x86_64-2.6.5/usr/local/mongodb
[Root @ data] # cd/usr/local/mongodb/
[Root @ mongodb] # chown-R mongodb: mongodb *
Configuration:
Add a boot entry for mongodb to CentOS
[Root @ vstar mongodb] # vi/etc/rc. d/rc. local
/Usr/local/mongodb/bin/mongod -- dbpath =/data/mongodb/-- logpath/var/mongodb/logs/log. log-fork
Start Method 1:
[Root @ mongodb] #/usr/local/mongodb/bin/mongod -- dbpath =/var/mongodb/data -- logpath/var/mongodb/logs/log. log-fork
The -- fork option indicates that MongoDB is run as a background service process.
The following information indicates that the installation is completed and started successfully:
Forked process: 18394
All output going to:/var/mongodb/logs/log. log
Start Method 2:
Create mongodb. conf
# Vi/etc/mongodb. conf
dbpath=/data/mongodblogpath=/var/log/mongodb/mongodb.loglogappend=tureport=27017rest=truefork=true
When calling mongodb, the-f option is usually used with the mongodb. conf file.
# Mongod-f mongodb. conf
You can also add this command to/etc/rc. local to enable mongodb to start up;
Test and verification
Method 1: Command Line
# Terminate a server process
Db. user. shutdownServer ()
# Entering the mongodb shell mode
[Root @ data] #/usr/local/mongodb/bin/mongo

Method 2: web Interface
When you access http: // ip: 27017, this message is displayed.
You are trying to access MongoDB on the native driver port. For http diagnostic access, add 1000 to the port number
It is actually a euphemism to tell you that you should access this port: http: // ip: 28017
If you have a root account, you can directly enter the root account and password for normal access!
