Introduction to the problem
After setting up heartbeat and running, I found that nginx and VIP cannot start normally. After checking the log, I found that nginx has been started but then stopped. I think through the error on the error log After a long time, I found that port 80 was occupied when I restarted nginx. Then I checked the process and found that port 80 was occupied by tomcat. After stopping tomcat and restarting the heartbeat service, I found that the problem was solved. Through this matter, we must learn from future studies and work. Be careful, don’t reduce work efficiency due to low-level mistakes! At the same time, it also shows that I have insufficient experience, so I have to study hard in the future!
