How to install appium

How to install appium through npm

Appium Server
Appium is a server written in Node.js

Warning: Appium Desktop is Not Appium

Appium Desktop is a graphical frontend to Appium with additional tools. Appium Desktop is released on its own cadence and has its own versioning system. If you are reporting an issue with Appium Desktop, always be sure to include both the version of Appium Desktop and the version of the Appium Server which is in use

  1. Install JAVA 8 and set JAVA_HOME variable and Path variable for java. 
  2. Install android sdk and set ANDROID_HOME variable and also set the adb path
In this article, I will show you how to install appium server and run the server through the command line. 


Download node.js from node.js website.  I will download the LTS version. 

Ensure you select to install the npm tools and the system paths:

Step 2:

Now I am going to install appium using npm command. 

If you want to install appium latest version then you need to use below command 

npm install -g appium

If you want to install appium specific version then you need to use below command 

npm install -g [email protected]

If you want to uninstall appium , you need to execute below command 

npm uninstall -g appium

In this blog, I am going to install appium version 1.7.2 

You will find appium installed under below path in your system

After installation appium we need to start appium server. 

appium -a -p 4723

where -a is the IP address (here localhost) and -p is the port

After the server run successfully you will see something like this 

How to setup Jenkins slave machine

How to setup Jenkins slave machine step by step guide

Jenkins is an open-source automation server, it can be used as automating all kind of task such as building project, testing, deploying project. In software development, DevOps is a very important process nowadays and Jenkins is an essential tool to follow the processes. It is really imported to know how to install Jenkins and set up the Jenkins slave.

Before downloading the Jenkins you need to download and install Java JDK.

Step 1:

Download Jenkins: Jenkins can be downloaded from below link
Jenkins Download

It will download a "jenkins.war" file.

Step 2:

Copy the .war file in a folder. I am copying "jenkins.war" file in my D:/java/ folder.

Step 3:

Open up a terminal in the download directory and run below command

java -jar jenkins.war --httpPort=8080

Here "--httpPort=8080" is optional field. By default, Jenkins runs on 8080 port, but if you want to change the port number then you have to mention the port number as mentioned above.

Step 4:

Once you run the command, Jenkins server starts working and configuration setup starts.

Please find the configuration procedure to setup Jenkins master

Create jenkins master

Step 5:  

Next, we need to setup Jenkins node from Jenkins master. Before creating Jenkins node we need to enable TCP port for JNLP agents. We can enable TCP port for JNLP agents from below steps

1. Click on Manage Jenkins
2. Click on Configure Global Security.
3. Click on the Random radio button beside  "TCP port for JNLP agents". 

Add a new node from Manage Jenkins -> Manage Nodes 

jenkins setup

We need to provide some information about the node. Once we click on the Manage Node link node page will open and we will see "New Node" link.  

Steps for adding a new node. 

1. Click on the New Node
2. Provide the node name 
3.Click on the radio button Permanent agents
4. Click Ok

Now we need to provide below details for newly created node  

Name: < Name of the Node e.g. slave 1>

Description: < Description of the project (This is an optional field)>

# of executors:
The maximum number of concurrent builds that Jenkins may perform on this agent.
The default value is 1.

Remote root directory: This is a mandatory field.

An agent needs to have a directory dedicated to Jenkins. Specify the path to this directory on the agent.
It is best to use an absolute path, such as /var/jenkins or c:\jenkins. This should be a path local to the
agent machine. There is no need for this path to be visible from the master.
e.g. c:\jenkins

Labels (or tags) are used to group multiple agents into one logical group.
For example, if you have multiple Windows agents and you have a job that must run on Windows, then
you could configure all your Windows agents to have the label windows, and then tie that job to this

This would ensure that your job runs on one of your Windows agents, but not on any agents without
this label.

Launch method
Controls how Jenkins starts this agent.

In my tutorial, I am using Launch agent Java Web Start.

I have created one slave with below configuration  

Once we have created slave node we can see newly created slave node displayed under Build Executor Status section on Jenkins home page. But we can see that node as offline mode like below 

How to start Jenkins slave machine 

1.  Open the Jenkins server from slave machine 
Suppose Jenkins server running on and Jenkins port is 8080 then you need to open Jenkins from another machine in the same network with 

2. Provide user name and password. 
3. Click on the Jenkins slave machine (In my case slave 1)
4. Click on the slave.jar hyper link, you will see slave.jar will be downloaded in slave machine.  You just need to copy that jar file into you slave Jenkins directory. I have created Jenkins directory in my d:/jenkins folder.  

5. Open command prompt or cmd and navigate to the folder where you paste or download the slave.jar 

6. Copy the command mentioned in the node 

java -jar slave.jar -jnlpUrl http://localhost:8080/computer/slave1/slave-agent.jnlp -secret e15c60d05ca37d01d593abd6297d6e3f1bb3b9d91c3c97d9155262acea8c61d3 -workDir "d:\jenkins"

You just need to change the ip address. You need to provide master machine ip address where the jenkins server is running. In my case, my server running on and post is 8080 , so command should be
 java -jar <a href="" style="box-sizing: border-box; color: #5c3566; word-wrap: break-word;">slave.jar</a> -jnlpUrl -secret e15c60d05ca37d01d593abd6297d6e3f1bb3b9d91c3c97d9155262acea8c61d3 -workDir "d:\jenkins"  

7. Paste the command in command prompt. and hit enter 

8 . Afer successfully executed the command Jenkins slave will be online.
