Mongo mongod init.d script not working on CentOS

Question

I am trying to figure out why the provided init.d script is not working on CentOS. I tried starting it manually:

/etc/init.d/mongod start

But I get the following error:

Starting mongod: /usr/bin/dirname: extra operand `2>&1.pid'
Try `/usr/bin/dirname --help' for more information.

I looked in the script where it tries to start:

  daemon --user "$MONGO_USER" "$NUMACTL $mongod $OPTIONS >/dev/null 2>&1"

So I looked where mongod var is defined:

mongod=${MONGOD-/usr/bin/mongod}

Also tried:

service mongod start

Same error.

Not sure what I have setup wrong, but I have verified that I have the latest script but I cannot get mongod process to start.

Any ideas???

I am seeing similar behavior on Red Hat Linux & MongoDB 2.6.5 - but MongoDB _does_ start regardless of this error. — Tommi, Nov 06 '14 at 06:53
@Tommi: for CentOS7 you might want to have a look at https://jira.mongodb.org/browse/SERVER-14679?filter=-2 — Markus W Mahlberg, Nov 20 '14 at 08:55

The following link appears to address the issue well https://ma.ttias.be/mongodb-startup-dirname-extra-operand-pid/

In a nutshell, a bad script appears to have been distributed but the output it produces is not harmful, mongod still runs. If you run yum update you'll get a fixed script, but likely mongod will still fail because the script was not making it fail. Check your mongo logs (usually /var/log/mongodb/mongod.log, but can be different if specified in differently in /etc/mongod.conf). The log file should tell you the real reason it's failing.

my mongod process did not start. I will upgrade to see If that fixes things — lostintranslation, Jan 17 '15 at 15:02

Check the mongo pid file location in the config file /etc/mongod.conf:

awk -F'[:=]' -v IGNORECASE=1 '/^[[:blank:]]*pidfilepath[[:blank:]]*[:=][[:blank:]]*/{print $2}' /etc/mongod.conf

By default there should be this line in mongod.conf: 'pidfilepath = /var/run/mongodb/mongod.pid'. Add it if it doesn't exist.

If you are using the YAML version of /etc/mongod.conf, check out this issue: https://jira.mongodb.org/browse/SERVER-13595. In short, you need to change this line in /etc/rc.d/init.d/mongod:

PIDFILE=`awk -F= '/^pidfilepath[[:blank:]]*=[[:blank:]]*/{print $2}' "$CONFIGFILE"`

to:

PIDFILE=`awk -F: '/^[[:blank:]]*pidFilePath[[:blank:]]*:[[:blank:]]*/{print $2}' "$CONFIGFILE" | tr -d ' '`

Cool, thanks I will try that. Quick note I can start mongod manually with my config file as well. mongod -f /etc/mongod.conf. Doesn't seem like a conf file issue, more so a init.d script issue. Also the Starting mongod: /usr/bin/dirname error is troublesome, should be trying to start /usr/bin/mongod, /usr/bin/dirname seems like a script variable is screwed up. – lostintranslation Nov 06 '14 at 17:34

For me problem was in pidfilepath. Init script can't deal with path in format like this

pidfilepath = /var/run/mongodb/mongod.pid

PIDFILE variable inside of init script contains ' /var/run/mongodb/mongod.pid' and not '/var/run/mongodb/mongod.pid'

FIX: replace PIDFILE line with this and it will work.

PIDFILE=awk -F= '/^pidfilepath[[:blank:]]*=[[:blank:]]*/{gsub(" ", "", $2);print $2}' "$CONFIGFILE"

Another solution may be https://github.com/mongodb/mongo/commit/50ca596ace0b1390482408f1b19ffb1f9170cab6 – Markus W Mahlberg Nov 20 '14 at 08:58

I have also faced the same issue.

The fix is to make a small change in the script file(/etc/init.d/mongod) as mentioned below:

line 63 i guess:

daemon --user "$MONGO_USER" "$NUMACTL $mongod $OPTIONS >/dev/null 2>&1"

to

daemon --user "$MONGO_USER" --pidfile "$PIDFILE" "$NUMACTL $mongod $OPTIONS >/dev/null 2>&1"

Hope this helps !!!

It could be a RedHat bug on the initscript package: goog.le forum redhat bugzilla
