[email protected] ~]# mv mongodb-linux-x86_64-rhel62-4.0.0//usr/local/mongodb #移动解压文件夹到MongoDB安装目录

[email protected] ~]# mkdir-p/home/data/mongodb/mongodb_data #创建MongoDB数据库存放路径

[email protected] ~]# mkdir-p/home/data/mongodb/mongodb_log #创建MongoDB数据库日志存放路径

#启动MongoDB

Server should is down ...
2018-07-22t21:25:17.131+0800 I NETWORK [JS] trying reconnect to 127.0.0.1:27017 failed
2018-07-22t21:25:17.131+0800 I NETWORK [JS] Reconnect 127.0.0.1:27017 failed failed

Bye

[Email protected] bin]# NETSTAT-ANTLP | GREP:27017 is closed.
[Email protected] bin]#

Once again enter the MongoDB database console when the following error:

[Email protected] bin]#./mongo
MongoDB Shell version v4.0.0
Connecting to:mongodb://127.0.0.1:27017
2018-07-22t22:07:54.310+0800 E QUERY [js] error:couldn ' t connect to server 127.0.0.1:27017, connection attempt failed: Socketexception:error Connecting to 127.0.0.1:27017:: Caused by:: Connection refused:

Exception:connect failed

Solution path:

(1) Cd/usr/local/mongodb/bin
(2)./mongod--dbpath=/home/data/mongodb/mongodb_data/

(3) The previous path setting is successful, but do not close the interface, you need to reopen a new window to start MONGO

(4) At another terminal: cd/usr/local/mongodb/
./bin/mongo

When doing the following, close the MongoDB database first

Ii. setting up a MongoDB database

[Email protected] bin]# cd/usr/local/mongodb/ #进入MongoDB安装目录

[Email protected] mongodb]# vim mongodb.conf #编写配置文件

port=27017 #端口号

dbpath=/home/data/mongodb/mongodb_data/ #数据库路径

Logpath=/home/data/mongodb/mongodb_log/mongodb.log #日志输出文件路径

Logappend=true #日志输出方式

[Email protected] ~]# cd/usr/local/mongodb/

[Email protected] bin]# pwd
/usr/local/mongodb/bin
[Email protected] bin]#/mongod-f mongodb.conf

To view ports:

Third, the Linux registered MongoDB service

Enter the/etc/init.d/directory

[Email protected] bin]# cd/etc/init.d/

Create a MongoDB file

[[email protected] init.d]# Vim MongoDB

#!/bin/sh
#
# # # # BEGIN INIT INFO
# Short-description:mongodb
# Description:mongo DB Server
# # # END INIT INFO


Program=/usr/local/mongodb/bin/mongod
Mongopid= ' Ps-ef | grep ' Mongod ' | Grep-v grep | awk ' {print $} '

Test-x $PROGRAM | | Exit 0

Case "$" in
Start
Ulimit-n 3000
echo "Starting MongoDB server"
$PROGRAM--fork--quiet-f/usr/local/mongodb/mongodb.conf
echo "Started MongoDB Server"
;;
Stop
echo "Stopping MongoDB server"
if [!-Z "$MONGOPID"]; Then
Kill-15 $MONGOPID
Fi
echo "Stopped MongoDB Server"
;;
Status
;;
*)
echo "Usage:mongodb {start|stop|status}"
Exit 1
Esac

Exit 0

After you have saved it, you can perform the following commands:

[Email protected] init.d]# chmod +x MongoDB

Test:

[[email protected] init.d]#/etc/init.d/mongodb start

[Email protected] init.d]# NETSTAT-ANTLP | grep:27017
