I feel a little confused recently. I don't know what to do. I went to work today to look at my monitoring data. I wonder if I can write the data into this non-relational database in mongodb for the sake of reading and writing speed. Here is how to learn mongodb:

1. Installation:

Download: http://fastdl.mongodb.org/linux/mongodb-linux-x86_64-2.6.3.tgz

[root@saltstack mongodb]# tar xvfz mongodb-linux-x86_64-2.6.3.tgz -C /usr/local/

[root@saltstack mongodb]# mv mongodb-linux-x86_64-2.6.3 mongodb

Edit the.bash_profile file, add the path to MongoDB, and refresh the file [root@saltstack mongodb]# vim .bash_profileMONGO_BIN=/usr/local/mongodb/bin

export PATH=$PATH:$MONGO_BIN

[root@saltstack mongodb]# source /root/.bash_profile

2. To facilitate management, configuration files and startup scripts are given:

(1)[root@saltstack mongodb]# cat /etc/mongod.conf

bind_ip=127.0.0.1

port=27017

fork=true

quiet=false

dbpath=/opt/mongodata

logpath=/opt/log/mongodb/mongod.log

logappend=true

journal=true

auth=true

(2)Create database file directory:

mkdir /opt/mongodata

(3)Set up the startup server script:

[root@saltstack mongodb]# cat /etc/init.d/mongod

#!/ bin/bash

config_file=/etc/mongod.conf

lock_file=/opt/mongodata/mongod.lock

bin_file=/usr/local/mongodb/bin/mongod

start(){

pid=`cat "$lock_file" 2>/dev/null`

if [ -z "$pid" ];then

"$bin_file" --config="$config_file"

echo "mongod is start! "

else

echo "mongod is running! "

fi

}

stop(){

pid=`cat "$lock_file" 2>/dev/null`

if [ -z "$lock_file" ];then

echo "mongod is not running! "

else

kill -2 $pid

echo "mongod is stop! "

fi

}

case "$1" in

start)

start

;;

stop)

stop

;;

restart)

stop

sleep 1

start

;;

*)

echo "Usage: $SCRIPTNAME {start|stop|restart}"

exit 3

;;

esac

exit 0

Start test after installation:

[root@saltstack mongodb]# /etc/init.d/mongod start

[root@saltstack mongodb]# mongostat
