MongoDB (4): A variety of ways to turn off service commands

http://blog.csdn.net/czw698/article/details/8791153

MongoDB provides several commands for shutting down the service, specifically the following:

One use crtl+c off

[Email protected] data]$ Mongod--dbpath=/database/mongodb/data/--logpath=/var/applog/mongo_log/mongo.log-- Logappend--port=27017--journal > Start_mongo.log 2>&1 Cursor: type crtl+c close

Note: If you start the MongoDB service as a foreground, the use of the "crtl+c" service will be turned off, which will wait for
The currently in progress operation is completed, so it is still a clean shutdown mode.

Two using the database command to close
--2.1 Open Service

[Email protected] data]$ mongod-f/database/mongodb/data/mongodb_27017.conf Forked process:18155 All output going to:/var/applog/mongo_log/mongo.log Child process started successfully, parent exiting

--2.2 Landing Database

[Email protected] data]$ MONGO MongoDB Shell version:2.2.1 Connecting To:test

--2.3 Close MongoDB Service

> Use admin; Switched to DB admin > db.shutdownserver (); Wed Nov 06:07:33 Dbclientcursor::init call () failed Wed Nov 06:07:33 Query failed:admin. $cmd {shutdown:1.0} to:127.0.0.1:27017 Server should is down ... Wed Nov 06:07:33 trying reconnect to 127.0.0.1:27017 Wed Nov 06:07:33 Reconnect 127.0.0.1:27017 failed couldnt connect to server 127.0.0.1:27017

Three use the Mongod command to close

[Email protected] data]$ mongod --shutdown --dbpath/database/mongodb/data/ Killing process with pid:17747

Note: The shutdown option of the Mongod command can cleanly shut down the MongoDB service.

Four using the KILL command
--4.1 viewing MONGO related processes

[Email protected] data]$ Ps-ef | grep MONGO Root 17573 14213 0 05:10 pts/1 00:00:00 Su-mongo MONGO 17574 17573 0 05:10 pts/1 00:00:00-bash MONGO 18288 1 0 06:12? 00:00:00 mongod-f/database/mongodb/data/mongodb_27017.conf MONGO 18300 17574 6 06:13 pts/1 00:00:00 ps-ef MONGO 18301 17574 0 06:13 pts/1 00:00:00 grep MONGO

--4.2 Kill MONGO Service process

[[email  Protected] data]$ kill 18288 [[email protected] data]$ ps-ef | grep pmon mongo    18304 17574&n Bsp 0 06:13 pts/1    00:00:00 grep pmon

Note: You can use the KILL command of the operating system to send a SIGINT or SIGTERM signal to the mongod process.
That is, "Kill-2 pid," or "kill-15 pid".

It is not recommended to use "kill-9 pid" because if MongoDB is running without logging on (--journal),
may result in data loss.
