Apache Troubleshooting
🛠️ Apache Troubleshooting | Linux Level-2 Series | Lab 21
Welcome to another real-world troubleshooting lab! In this task, you’ll identify and fix Apache service issues across multiple servers in the Stratos Datacenter.
📌 Lab Objective:
Detect the faulty application server and ensure Apache is running properly on all servers.
🛠️ Task Requirements:
Identify the server where Apache is failing
Ensure Apache runs on port 3004
Document root must be: /var/www/html
Apache must be running on ALL app servers
Do NOT disable firewall
Verify using curl from jump host
💻 Step-by-Step Solution:
🔹 1. Check Apache status on all servers
ssh stapp01 "systemctl status httpd"
ssh stapp02 "systemctl status httpd"
ssh stapp03 "systemctl status httpd"
👉 Identify the faulty server (service failed or inactive)
🔹 2. Fix Apache configuration (on faulty server)
vi /etc/httpd/conf/httpd.conf
🔧 Ensure:
Listen 3004
DocumentRoot "/var/www/html"
⚠️ Remove any ; at the end of paths
🔹 3. Start & enable Apache
systemctl restart httpd
systemctl enable httpd
🔹 4. Test from jump host
curl http://stapp01:3004
curl http://stapp02:3004
curl http://stapp03:3004
