The linux jdk directory is in the bin directory. The specific search method is: 1. Find the execution directory of javad through the "whereis java" command; 2. Find the link file through the execution file; 3. Through "ls -lrt / etc/alternatives/java" command to find the installation directory.
#The operating environment of this tutorial: linux5.9.8 system, Dell G3 computer.
Where is the linux jdk directory?
linux view jdk installation directory
1. jdk installed by installation package
If you are installing the current installation package, you will generally configure the environment variables
echo $JAVA_HOME
or view /etc/profile
vi /etc/profile
2. yum installation View the installation directory
I am lazy, so I installed it using yum.
whereis java
ls -lrt /usr/bin/java
ls -lrt /etc/alternatives/java
cd /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.191.b12-1.el7_6.x86_64-debug/jre/bin

Linux Operations: Shell Scripting and AutomationMay 04, 2025 am 12:15 AMShell scripts are powerful tools for automated execution of commands in Linux systems. 1) The shell script executes commands line by line through the interpreter to process variable substitution and conditional judgment. 2) The basic usage includes backup operations, such as using the tar command to back up the directory. 3) Advanced usage involves the use of functions and case statements to manage services. 4) Debugging skills include using set-x to enable debugging mode and set-e to exit when the command fails. 5) Performance optimization is recommended to avoid subshells, use arrays and optimization loops.
Linux Operations: Understanding the Core FunctionalityMay 03, 2025 am 12:09 AMLinux is a Unix-based multi-user, multi-tasking operating system that emphasizes simplicity, modularity and openness. Its core functions include: file system: organized in a tree structure, supports multiple file systems such as ext4, XFS, Btrfs, and use df-T to view file system types. Process management: View the process through the ps command, manage the process using PID, involving priority settings and signal processing. Network configuration: Flexible setting of IP addresses and managing network services, and use sudoipaddradd to configure IP. These features are applied in real-life operations through basic commands and advanced script automation, improving efficiency and reducing errors.
Linux: Entering and Exiting Maintenance ModeMay 02, 2025 am 12:01 AMThe methods to enter Linux maintenance mode include: 1. Edit the GRUB configuration file, add "single" or "1" parameters and update the GRUB configuration; 2. Edit the startup parameters in the GRUB menu, add "single" or "1". Exit maintenance mode only requires restarting the system. With these steps, you can quickly enter maintenance mode when needed and exit safely, ensuring system stability and security.
Understanding Linux: The Core Components DefinedMay 01, 2025 am 12:19 AMThe core components of Linux include kernel, shell, file system, process management and memory management. 1) Kernel management system resources, 2) shell provides user interaction interface, 3) file system supports multiple formats, 4) Process management is implemented through system calls such as fork, and 5) memory management uses virtual memory technology.
The Building Blocks of Linux: Key Components ExplainedApr 30, 2025 am 12:26 AMThe core components of the Linux system include the kernel, file system, and user space. 1. The kernel manages hardware resources and provides basic services. 2. The file system is responsible for data storage and organization. 3. Run user programs and services in the user space.
Using Maintenance Mode: Troubleshooting and Repairing LinuxApr 29, 2025 am 12:28 AMMaintenance mode is a special operating level entered in Linux systems through single-user mode or rescue mode, and is used for system maintenance and repair. 1. Enter maintenance mode and use the command "sudosystemctlisolaterscue.target". 2. In maintenance mode, you can check and repair the file system and use the command "fsck/dev/sda1". 3. Advanced usage includes resetting the root user password, mounting the file system in read and write mode and editing the password file.
Linux Maintenance Mode: Understanding the PurposeApr 28, 2025 am 12:01 AMMaintenance mode is used for system maintenance and repair, allowing administrators to work in a simplified environment. 1. System Repair: Repair corrupt file system and boot loader. 2. Password reset: reset the root user password. 3. Package management: Install, update or delete software packages. By modifying the GRUB configuration or entering maintenance mode with specific keys, you can safely exit after performing maintenance tasks.
Linux Operations: Networking and Network ConfigurationApr 27, 2025 am 12:09 AMLinux network configuration can be completed through the following steps: 1. Configure the network interface, use the ip command to temporarily set or edit the configuration file persistence settings. 2. Set up a static IP, suitable for devices that require a fixed IP. 3. Manage the firewall and use the iptables or firewalld tools to control network traffic.
