我嘗試使用命令mongod
開始的mongod從/etc/init.d中的文件夾的過程,但我得到了下面的錯誤啓動mongod的過程:無法在RedHat
2016-11-14T16:26:55.264+0530 I CONTROL [initandlisten] MongoDB starting : pid=16092 port=27017 dbpath=/data/db 64-bit host=xyz

上述錯誤說,這是無法找到dbpath,但mongod腳本文件應該從/etc/mongod.conf文件中選擇配置,我已經提到了dbpath,在這裏我從mongod腳本文件中提取了一些內容,通過它我們知道它是假設選擇配置從/etc/mongod.conf文件:
#!/bin/bash
# mongod - Startup script for mongod
# chkconfig: 35 85 15
# description: Mongo is a scalable, document-oriented database.
# processname: mongod
# config: /etc/mongod.conf
# pidfile: /var/run/mongodb/mongod.pid
. /etc/rc.d/init.d/functions
# things from mongod.conf get there by mongod reading it
# NOTE: if you change any OPTIONS here, you get what you pay for:
# this script assumes all options are in the config file.
CONFIGFILE="/etc/mongod.conf"
OPTIONS=" -f $CONFIGFILE"
SYSCONFIG="/etc/sysconfig/mongod"
這裏有來自mongod.conf文件中的一些contetns:
# mongod.conf
# for documentation of all options, see:
# http://docs.mongodb.org/manual/reference/configuration-options/
# where to write logging data.
systemLog:
destination: file
logAppend: true
path: /var/log/mongodb/mongod.log
# Where and how to store data.
storage:
dbPath: /var/lib/mongo
journal:
enabled: false
# engine:
mmapv1:
smallFiles: true
# wiredTiger:
我能夠通過在命令本身指定--dbpath選項來啓動mongod的過程如下:
mongod --dbpath /var/lib/mongo
但我想知道原因,爲什麼它不從/etc/mongod.conf文件中選擇dbpath。
在此先感謝。
