nginx failed to start

1. Common problems when nginx fails to start

Unsuccessful startup of port occupation, pass

netstat -aon|findstr "8080" 

TCP     127.0.0.1:80         0.0.0.0:0               LISTENING       2448

Check and close the port 

taskkill /f /im notepad.exe   名称关闭
taskkill /f /pid 2152         通过pid强行关

80 is occupied, can’t get up, find the process can’t be shut down, the system is occupied

taskkill /f /im notepad.exe
taskkill /f /pid 2152

The sqlserver configuration manager found that the sqlserver reporting services service stopped,

Re netstat -ano 

Port 80 inside is gone
