Today we will learn how to use commands to configure Java and node environments in Yunyao Cloud Server L instance (Yunyao Cloud Server itself has installed pagoda services, and can visually install MySQL, JDK, Apache, nginx and other services).
1. Task dismantling
1. Change password;
2. Configure security rules;
3. Remote login and update apt;
4. Install and configure JDK environment; 5.
Install and configure git;
6. Install and configure Maven;
7. Install and configure node;
2. Change the password
- Open https://www.huaweicloud.com/ interface
- Click on "Console"
- In the "Console", select the "Resource Management" tab, select "Cloud Server"
- Select "More", click "Reset Password"
- Set a new password and restart the cloud server (when setting the password, you can check "Auto Restart")
3. Configure security rules
- Go to the "Security Group" tab, click "Configure Rules" (default sg-default-smb)
- Configure rules, generally we will choose "inbound rules" (others access ports on our server)
- We can click "One-click Settings" to open common ports: 80, 3306, 443, 8080, etc.
- You can also add rules to add the ports you want to open (see the cloud service provider's own network security configuration for details)
Fourth, log in remotely and update apt
- This machine is a Mac computer, open the terminal, and enter the command: ssh root@cloud host’s elastic external network IP (Windows computers need to download and install xshell, putty and other software for remote login)
- After logging in successfully, enter the command: sudo apt update (the screenshot is the updated status)
5. Install and configure the JDK environment
5.1. Install openjdk and choose version 8
安装命令
sudo apt install openjdk-8-jdk
5.2. Check jdk configuration
check command
java -version
If openjdk version 1.8.0_382 appears in the figure, it means that the JDK configuration is successful;
at this time, the JDK version 1.8 is generally called jdk8, jdk1.8, jdk18
6. Install and configure git
6.1, install git
install command
sudo apt install git
6.2. Check git configuration
Check git version command
git --version
As shown in the figure, git version 2.34.1, git installation configuration is successful
7. Install and configure Maven
The Maven version corresponding to JDK8 we need: between 3.3 and 3.8 (the maven version installed on Huawei Yunyaoyun server apt is 3.6, which meets the conditions; if not, you need to go to the Maven official website to download the specified version to install and configure)
7.1. Install Maven
install command
sudo apt install maven
Encountered the option y/n during installation, just select y
7.2. Check maven configuration
Check maven version command (version of this server: 3.6.3)
mvn -v
8. Install and configure node
8.1. Install node and npm
Ubuntu installs node and npm command line commands
sudo apt install nodejs-legacy
sudo apt install npm
Encountered the option y/n during installation, just select y
8.2. Check node and npm configuration
Check node version command (version of this server: 12.22.9)
mvn -v
Check npm version command (version of this server: 8.5.1)
npm -v
Summarize
The above is what I want to talk about today. This article only briefly introduces the installation and configuration of JDK, git, and Maven required for the back end, and the installation and configuration of Node and Npm required for the front end. Then continue to write and deploy the Springboot project on the Linux server , Run the vue3 project on the linux server.
