本文详细介绍了Nginx启动时遇到端口已占用错误的解决步骤，包括查看网络状态、找到占用端口的进程并终止它，从而顺利启动Nginx服务。同时提供了网络状态查询命令和端口占用情况展示，帮助开发者快速定位问题。

启动nginx的时候输出：

root@wl-Lenovo-B590:/usr/local/nginx/sbin# ./nginx
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] still could not bind()
root@wl-Lenovo-B590:/usr/local/nginx/sbin#

这个主要是由于该端口被其他程序占用，只要把占用该端口的进程杀掉就可一了

root@wl-Lenovo-B590:/usr/local/nginx/sbin# ./nginx
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:8100 failed (98: Address already in use)
nginx: [emerg] still could not bind()
root@wl-Lenovo-B590:/usr/local/nginx/sbin# netstat -ntpl
激活Internet连接 (仅服务器)

root@wl-Lenovo-B590:/usr/local/nginx/sbin# ./nginx
root@wl-Lenovo-B590:/usr/local/nginx/sbin#

杀掉后就可以正常运行了，当然了，每个人设置的监听端口不一样，杀掉占用自己设置的端口的进程就好了
