The learning process of mongodb
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
