MongoDB provides 64-bit installation packages for all linux distributions, which you can download from the official website.

We need to install each Linux platform dependency package before installation.

Red Hat/CentOS:

sudo yum install libcurl openssl 

Ubuntu 18.04 LTS (“Bionic”)/Debian 10 “Buster”:

sudo apt-get install libcurl4 openssl 

Ubuntu 16.04 LTS (“Xenial”)/Debian 9 “Stretch”:

sudo apt-get install libcurl3 openssl 

MongoDB source code download address: https://www.mongodb.com/download-center#community

Here we choose tgz to download, download the installation package, and extract it. tgz (the installation on 64-bit Linux is demonstrated below).

wget https://fastdl.mongodb.org/linux/mongodb-linux-x86_64-ubuntu1604-4.2.8.tgz # 下载 tar -zxvf mongodb-linux-x86_64-ubuntu1604-4.2.8.tgz # 解压 mv mongodb-src-r4.2.8 /usr/local/mongodb4 # 将解压包拷贝到指定目录 

The executable file for MongoDB is located in the bin directory, so you can add it to the PATH In path:

export PATH=/bin:$PATH    

The installation path for your MongoDB. As in this article /usr/local/mongodb4 .

export PATH=/usr/local/mongodb4/bin:$PATH 

3.5.1. Create a database directory

By default, the following two directories are initialized when MongoDB starts:

  • Data storage directory: / var/lib/mongodb

  • Log file directory: / var/log/mongodb

Before starting, we can create these two directories and set the current user to have read and write permissions:

sudo mkdir -p /var/lib/mongo sudo mkdir -p /var/log/mongodb sudo chown `whoami` /var/lib/mongo # 设置权限 sudo chown `whoami` /var/log/mongodb # 设置权限 

Next, start the Mongodb service:

mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log --fork 

Open the / var/log/mongodb/mongod.log file and see the following message indicating that the startup was successful.

# tail -10f /var/log/mongodb/mongod.log 2020-07-09T12:20:17.391+0800 I NETWORK [listener] Listening on /tmp/mongodb-27017.sock 2020-07-09T12:20:17.392+0800 I NETWORK [listener] Listening on 127.0.0.1 2020-07-09T12:20:17.392+0800 I NETWORK [listener] waiting for connections on port 27017 

3.5.2. MongoDB backend manages Shell

If you need to enter the mongodb background management, you need to first open the bin directory under the mongodb installation directory, and then execute the mongo command file.

MongoDB Shell is an interactive Javascript shell that comes with MongoDB, which is used to operate and manage MongoDB.

When you enter the mongoDB background, it will link to the test document (database) by default:

$ cd /usr/local/mongodb4/bin $ ./mongo MongoDB shell version v4.2.8 connecting to: mongodb://127.0.0.1:27017/?compressors=disabled&gssapiServiceName=mongodb Implicit session: session { "id" : UUID("2cfdafc4-dd56-4cfc-933a-187b887119b3") } MongoDB server version: 4.2.8 Welcome to the MongoDB shell. …… 

Because it is a JavaScript shell, you can run some simple arithmetic operations:

> 2+2 4 > 3+6 9 

Now let’s insert some simple data and retrieve the inserted data:

> db.runoob.insert({x:10}) WriteResult({ "nInserted" : 1 }) > db.runoob.find() { "_id" : ObjectId("5f069bdb4e02f8baf90f1184"), "x" : 10 } > 

The first command inserts the number 10 into the x field of the runoob collection.

To stop mongodb, you can use the following command:

mongod --dbpath /var/lib/mongo --logpath /var/log/mongodb/mongod.log --shutdown 

It can also be found in mongo To implement in the command exit of

> use admin switched to db admin > db.shutdownServer() 

More installation methods can be found on the official website: https://docs.mongodb.com/manual/administration/install-on-linux/

《地理信息系统原理、技术与方法》  97

最近几年来,地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持,如城市管理、区划、环境整治等等,地理信息成为信息时代重要的组成部分之一; “数字地球”概念的提出,更进一步推动了作为其技术支撑的GIS的发展。 与此同时,一些学者致力于相关的理论研究,如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面,并且这两个方面构成了相互促进的发展过程。
