niginx 问题：nginx[14701]: nginx: [emerg] bind() 至 [::]:80 失败 (98: 地址已在使用中)

Question

我正在尝试安装 ph8。我之前在 nginx 下运行的是 php7.4。当我执行以下命令时：

@lc2530hz：~$ journalctl -xe

Jun 04 16:46:22 lc2530hz nginx[14701]: nginx: [emerg] bind() to [::]:80 failed (98: Address alre
Jun 04 16:46:22 lc2530hz rtkit-daemon[3488]: Supervising 5 threads of 3 processes of 1 users.
Jun 04 16:46:22 lc2530hz rtkit-daemon[3488]: Supervising 5 threads of 3 processes of 1 users.

然后我尝试了以下命令：

$     sudo netstat -plant | grep 80

请有人指导我如何解决这个问题。

@waltinator 你好，我得到了与上面相同的答案，即 firsfox 和 nginx 共享端口 80。
