How to deploy nodejs to linux and run hello world

First install VMware

1. Download VMware

Because we don’t have the need to program on linux (unless you are a big deal | | Pretentious master), so we chose to install Linux on the virtual machine. The current mainstream virtual machine platforms are VMware and virtualbox. The former is paid, and the latter is a free version. You can install it at will, we use VMware

2. Install VMware

Double-click the downloaded installation package file to start the installation...

a. For me who have obsessive-compulsive disorder, just download this interface One step at a time, there’s nothing wrong with me^-^

b. If you don’t agree with this, then it’s over. v_v

c. Here comes the key point. For some programmers with mysophobia who are unwilling to install application software to their own c drive, they need to click the change button on this interface

d. I don’t know if you have any magic operation. As a lazy person, I just replaced C with D

e. Then comes the crazy next step--> Finally click install, and the computer will start working

##f. After the installation is completed, the following interface pops up. Here we click the license button (it is strongly recommended that everyone buy the genuine version)

g. Enter After entering the license page input interface, I unknowingly thought of Du Niang. Here again, I strongly recommend that everyone use genuine software.

##h. Click Finish on the final completion page. At this point, the VMware installation is complete

Secondly install linux

1. Download linux

About I won’t go into details about the myth of the birth of Linux here. Let’s just take the screenshots and walk through the steps.

2. Install linux

a. Double-click the VMware button on the desktop to open it, and click the huge "New Virtual Machine" button

b. Select Typical and click Next. If the system does not match the Linux installation package you downloaded on this page, you need to manually select it

c. Here you need to give your virtual machine a name

d. Old rules C->D

e. If you don’t know much about these things, just go to the next step and complete the virtual machine configuration.

f. The good thing about VMware is that so far, we don’t have to do anything. You can flirt with girls and play LOL. Because VMware has done the rest of the work for us.

#g. After the installation was completed, we entered the Linux interface we had longed for. It was not as bad as imagined^-^

h. Use xshell to link to linux

a) Installing xshell is really not difficult and I won’t go into it here. First we get the virtual The ip of the machine

Click the linux button-> In the password box, enter the password we set when installing the virtual machine-> After completing the basic settings-> you can enter

liunx Desktop-> Right-click-> open in terminal to open the liunx console and enter the ifconfig command and press Enter

#b) Open xshell and use the alt n shortcut key

before entering the host name Obtain the ip in one step

##c) in xshell The output of ifconfig entered in is the same as that output in the virtual machine. The xshell link is successful

1. Enter the installation directory

 cd /usr/local/

2. Upload nodejs installation package

rz -> Select the downloaded node installation package file

3. Unzip the nodejs installation package

 xz -d node-v8.1.2-linux-x64.tar.xz
 tar -xvf node-v8.1.2-linux-x64.tar

4. Change the name

 mv node-v8.1.2-linux-x64 node

5. Add environment variables

 vim /etc/profile  -> 并在文件的末尾添加三行 (vim 操作请自行百度)
 export NODE_HOME=/usr/local/node
 export PATH=$PATH:$NODE_HOME/bin
 export NODE_PATH=$NODE_HOME/lib/node_modules
 配置完成后执行 
 source /etc/profile
 在命令行中输入 node -v 是不是好使了 ^-^
 为了保证每个账户下该配置均可用需要
 vim /root/.bashrc
 并在这个文件的末尾加上
 source etc/profile
 万事大吉 撒花.....

6. Create hello world program

mkdir -p /usr/local/demo/
vim /usr/local/demo/helloworld.js

Enter the following content in the helloworld.js file

var http = require('http');
http.createServer(function(req, res) {
res.end('hello world...')
}).listen(8080);
console.log('服务已启动, 监听端口8080......')

At this point we can access the service through the virtual machine itself

Access the node service through the virtual machine

But in the physical The host cannot access

Why is this? Turn off the firewall

Baidu spent a long time and found that the firewall should be turned on for the virtual machine, so the physical host cannot be accessed. Execute the following Just two commands.

systemctl stop firewalld.service #停止firewall
systemctl disable firewalld.service #禁止firewall开机启动
