要添加键服务器，请使用以下命令–
$ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
样本输出应如下所示–
Executing: /tmp/tmp.IagxypDbAy/gpg.1.sh --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927 gpg: requesting key EA312927 from hkp server keyserver.ubuntu.com gpg: key EA312927: public key "MongoDB 3.2 Release Signing Key " imported gpg: Total number processed: 1 gpg: imported: 1 (RSA: 1)
要添加mongoDB PPA，请使用以下命令–
$ echo "deb http://repo.mongodb.org/apt/ubuntu "$(lsb_release -sc)"/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb.list
现在更新添加的软件包，使用以下命令–
$ sudo apt-get update
要安装MongoDB，请使用以下命令–
$ sudo apt-get install mongodb-org
样本输出应如下所示–
Reading package lists... Done Building dependency tree Reading state information...

要下载解析服务器文件，请使用以下命令-
$ sudo git clone https://github.com/ParsePlatform/parse-server-example.git
样本输出应如下所示–
Cloning into 'parse-server-example'... remote: Counting objects: 312, done. remote: Total 312 (delta 0), reused 0 (delta 0), pack-reused 312 Receiving objects: 100% (312/312), 77.77 KiB | 0 bytes/s, done. Resolving deltas: 100% (144/144), done. Checking connectivity... done.
要进入parse-server-example目录，请使用以下命令–
$ cd parse-server-example
使用npm，如下所示安装parse-server –
/parse-server-example$ sudo npm install
样本输出应如下所示–

现在打开index.js文件，添加APP_ID和MASTER_KEY，如下所示–
$ sudo nano index.js
使用任意随机字符串作为APP_ID和MASTER_KEY，如下所示-
var api = new ParseServer({
databaseURI: databaseUri || 'mongodb://localhost:27017/dev',
cloud: process.env.CLOUD_CODE_MAIN || __dirname + '/cloud/main.js',
appId: process.env.APP_ID || 'nhooosample',
masterKey: process.env.MASTER_KEY || 'samplecreatedbysairam', //Add your mast$
serverURL: process.env.SERVER_URL || 'http://localhost:1337/parse', // Don't$
liveQuery: {
classNames: ["Posts", "Comments"] // List of classes to support for query s$
}
});现在保存并关闭文件。要启动解析服务器，请使用以下命令–
$ sudo npm start
样本输出应如下所示–
> parse-server-example@1.4.0 start /opt/parse-server-example > node index.js DATABASE_URI not specified, falling back to localhost. parse-server-example running on port 1337. info: Parse LiveQuery Server starts running ....................................................................
