how to set mogodb in upstart service with authentication

问题

I have created a superuser tom in mongodb v2.6.11 with username & password and now i want to add this at ubuntu startup service

on searching came to know that i have to edit below file

this is how my /etc/init/mongod.conf looks

pre-start script
    mkdir -p /var/lib/mongodb/
    mkdir -p /var/log/mongodb/
end script

start on runlevel [2345]
stop on runlevel [06]

script
  ENABLE_MONGOD="yes"
  CONF=/etc/mongod.conf
  DAEMON=/usr/bin/mongod
  DAEMONUSER=${DAEMONUSER:-mongodb}

  if [ -f /etc/default/mongod ]; then . /etc/default/mongod; fi

  # Handle NUMA access to CPUs (SERVER-3574)
  # This verifies the existence of numactl as well as testing that the command works
  NUMACTL_ARGS="--interleave=all"
  if which numactl >/dev/null 2>/dev/null && numactl $NUMACTL_ARGS ls / >/dev/null 2>/dev/null
  then/etc/init/mongod.conf
    NUMACTL="$(which numactl) -- $NUMACTL_ARGS"
    DAEMON_OPTS=${DAEMON_OPTS:-"--config $CONF"}
  else
    NUMACTL=""
    DAEMON_OPTS="-- "${DAEMON_OPTS:-"--config $CONF"}
  fi

  if [ "x$ENABLE_MONGOD" = "xyes" ]
  then
    exec start-stop-daemon --start --chuid $DAEMONUSER --exec $NUMACTL $DAEMON $DAEMON_OPTS
  fi
end script

ATTEMPT 1 :by using mongo command line

sudo mongod --auth --port 27017 --dbpath /var/lib/mongodb

but don't know what to change in /etc/init/mongod.conf ?

ATTEMPT 2 :by using /etc/mongod.conf

Did Changes In /etc/mongod.conf

auth = true

port = 27017

$sudo mongod --config /etc/mongod.conf

Observation : Unable to create/open lock file: /var/lib/mongodb/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating I found this Error in log .Don't know if it causing mongodb to terminate.if it is causing mongo to STOP at computer start then how to set permisssion ?

回答1:

There is absolutely no need to fiddle with the startup files (which you really should not do unless you exactly know what you are doing) or install additional software for managing MongoDB.

I'd rather suggest to read MongoDB's extensive documentation of the config file options.

The only thing you need to do is to set

auth=true

for legacy config files or

security:
  authorization: enabled

for YAML config files in /etc/mongod.conf

回答2:

Alternatively possible to use supervisor:

apt install supervisor

Setting for process mongodb:

create file myupstartservice.conf at location /etc/supervisor/conf.d and put below code

[program:mongo]
command=/usr/bin/mongod --auth --config /etc/mongod.conf
autostart=true
autorestart=true
user=root
priority=100

then checkservice

service supervisor restart

Thanks @Markus W mahalberg extending your answer in detailed steps

Correct Mongodb Way to set mongo in startup with authentication

Steps :

1 : sudo apt-get install mongodb-org - in new terminal

2 : sudo mongod --port 27017 --dbpath /var/lib/mongodb

3 : mongo --port 27017 - in new terminal

4 : use admin

5 : Lets setup superuser

db.createUser(
{
    user: "tom",
    pwd: "jerry",
    roles: [
              { role: "userAdminAnyDatabase", db: "admin" },
              { role: "readWriteAnyDatabase", db: "admin" },
              { role: "dbAdminAnyDatabase", db: "admin" },
              { role: "clusterAdmin", db: "admin" }
           ]
})

6 : Lets configure for Startup service for that Do Changes In /etc/mongod.conf and set

auth = true

port = 27017

7 : sudo /etc/init.d/mongod stop OR sudo service mongod stop - in new terminal

8 : sudo /etc/init.d/mongod start OR sudo service mongod start

9 : restart your pc and before restarting your pc please empty this file /var/log/mongodb/mongod.log and save

Now lets check TWO things Authentication & mongodb running at startup

1 :Check Authentication setup

mongo --port 27017 -u "tom" -p "jerry" --authenticationDatabase "admin" - in new terminal

Note : this step is most important step .

it will give Output on terminal like

MongoDB shell version: 2.6.11
connecting to: 127.0.0.1:27017/test
>

2 :Check if mongodb is running at startup

Run below command without running `mongod` as mongod should have started in startup

mongo --port 27017 -u "tom" -p "jerry" --authenticationDatabase "admin" - in new terminal

If it dosent start then open this file '/var/log/mongodb/mongod.log' .

if it contains Error log :

Unable to create/open lock file: /var/lib/mongodb/mongod.lock errno:13 Permission denied Is a mongod instance already running?, terminating

Then apply these permissions and restart and again check

sudo chown -R mongodb:mongodb /var/lib/mongodb/.
sudo chown -R mongodb:mongodb /var/log/mongodb/mongod.log
sudo /etc/init.d/mongod stop` OR `sudo service mongod stop    
sudo /etc/init.d/mongod start` OR `sudo service mongod start

If it does not contains above error log then you should have successfully started mongodb at startup

回答4:

1 : Got to -> $cd /etc/init/

2 :Through vi Or nano editor Create file myservice.conf with below code

description "service to start mongodb at startup"
author "plutopunch :)"

start on started mountall
stop on shutdown

respawn
respawn limit 99 5

script
     export HOME="/home/admin"

     exec sudo mongod --port 27017 --auth --dbpath /var/lib/mongodb
end script

post-start script
end script

3 : restart pc
