认证概述
CompTIA Linux+(LX0-104)是 LPIC-1(Linux Professional Institute Certification Level 1)的第二门考试,对应 LPI Exam 102。如果说 LX0-103 打牢了 Linux 命令行基础,那 LX0-104 就是把这些基础用起来:写 Bash 脚本自动化运维任务、配置 SSH 无密码登录、管理用户账户和 cron 计划任务、以及排查网络连通性问题。通过 LX0-103 + LX0-104 后可同时获得 CompTIA Linux+ 和 LPIC-1 双重认证,在 Linux 运维岗位上有显著竞争优势。
考试领域
- Shell 脚本与数据管理(Shell Scripting and Data Management):Bash 变量、条件判断(if/case)、循环(for/while/until)、函数、SQL 基础查询
- 用户界面与桌面(User Interfaces and Desktops):X11 架构与配置、桌面环境(GNOME/KDE)安装、显示管理器(GDM/SDDM)
- 管理任务(Administrative Tasks):用户与组账户管理(useradd/usermod/groupadd)、cron 和 at 计划任务、本地化与时区设置
- 网络基础(Networking Fundamentals):TCP/IP 配置(ip/ifconfig)、路由表管理、DNS 客户端(/etc/resolv.conf)、网络故障排查(ping/traceroute/netstat/ss)
- 安全(Security):SSH 密钥认证配置、iptables 防火墙规则、GPG 数据加密与签名、主机安全加固
适合人群
已通过或正在备考 LX0-103 的学习者,目标是完成完整 LPIC-1 认证。Linux 系统管理员日常需要写脚本自动化任务、配置网络和管理用户权限的 IT 工程师,这门考试验证的正是这类实际工作能力。

Before you register
What core topics does the LX0-104 exam cover?
LX0-104 corresponds to LPIC-1 Exam 102 and covers: Shell scripting and data management (Bash scripting, SQL basics), User interfaces and desktops (X11 configuration), Administrative tasks (user account management, cron scheduling), Network fundamentals (TCP/IP configuration, DNS, troubleshooting), and Security (iptables, SSH, GPG).
Do I need to take LX0-104 and LX0-103 together?
The two exams can be taken separately in any order. However, to earn the full LPIC-1 / CompTIA Linux+ certification, both LX0-103 and LX0-104 must be passed within a five-year validity period. It is recommended to take 103 (system fundamentals) first, then 104 (networking and security).
How difficult is the Shell scripting section in LX0-104?
Shell scripting is both a key focus and the most challenging part of LX0-104. The exam requires knowledge of Bash variables, conditionals (if/case), loops (for/while), and functions. You do not need to write very complex scripts, but you should be able to read and write basic automation scripts. Practice extensively in the terminal.
How much of the exam covers networking topics?
Network fundamentals is a significant domain in LX0-104. You need to master TCP/IP basics, network interface configuration (ifconfig/ip), routing tables, DNS client configuration (/etc/resolv.conf), and basic troubleshooting tools (ping, traceroute, netstat).
How should I effectively prepare for the LX0-104 exam?
Focus on mastering Shell scripting and network configuration. Practice writing Bash scripts, configuring network parameters, and setting up SSH key authentication in a real Linux environment. Use this bank of 77+ practice questions to solidify your knowledge, keeping in mind the 60-question/90-minute exam pace with a passing score of 500/800.
