Centos5.9 Install MongoDB Database steps

Today we have to install the MongoDB bar, this is a database, in order to lazy, this article on the use of Yum installation, after all, yum convenient, rely on the package will be installed, unless it is a separate entire DB server to compile the installation.
System: CentOS 5.9
1. Pre-Installation Preparation
This is for a 64-bit system Yum Source:
echo "[MongoDB]
Name=mongodb Repository
Baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/x86_64
Gpgcheck=0
Enabled=1 "| sudo tee-a/etc/yum.repos.d/mongodb.repo

This is for a 32-bit system Yum source
echo "[MongoDB]
Name=mongodb Repository
baseurl=http://downloads-distro.mongodb.org/repo/redhat/os/i686
Gpgcheck=0
Enabled=1 "| sudo tee-a/etc/yum.repos.d/mongodb.repo

2. Install MongoDB
Yum-y Install Mongo-10gen Mongo-10gen-server

3. Configure MongoDB
Cat/etc/mongod.conf

#quota = True
# Set Oplog record level
# Set oplogging level where n is
# 0=off (default)
# 1=w
# 2=r
# 3=both
# 7=w+some Reads
#oplog = 0

#nohints = True
# Disable HTTP interface, default to localhost:28017
# Disable The HTTP interface (Defaults to localhost:27018). This port number is written incorrectly.
#nohttpinterface = True

# Close server-side scripts, which will greatly restrict functionality
# Turns off server-side scripting. This'll result in greatly limited
# functionality
#noscripting = True
# Close Scan table, any query will be scan failed
# Turns off table scans. Any query so would do a table scan fails.
#notablescan = True
# Close data file pre-allocation
# Disable data File preallocation.
#noprealloc = True
# Specify the size of the. ns file for the new database, in megabytes: MB
# specify. ns file size for new databases.
# nssize = <size>

# Accout token for Mongo monitoring server.
#mms-token = <token>
# MONGO the name of the monitor server
# server name for Mongo monitoring server.
#mms-name = <server-name>
# MONGO The ping interval of the monitor server
# Ping interval for Mongo monitoring server.
#mms-interval = <seconds>

# Replication Options Replication option

# in replicated MONGO databases, specify here whether this is a slave or master in replication, specifies that the current is a subordinate relationship
#slave = True
#source = master.example.com
# Slave only:specify A single database to replicate
#only = master.example.com
# or
#master = True
#source = slave.example.com

These are some of the parameters in the default configuration file, and more parameters can be viewed with the mongod-h command

5. Start MongoDB
Service Mongod Start
Chkconfig Mongod on

If the startup display succeeds, you can enter at the command line:
Mongo
Test and manipulate the database. MONGODB CREATE database and configure user methods
