排错集锦2 nginx安装开启失败

Posted 2021-06-29 遙遙背影暖暖流星

问题：对安装对启动路径进行了优化，现在可以利用systemctl进行管理，但发现启动不了

如图

nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (98: Address already in use)
nginx: [emerg] still could not bind()

解决方法：
lsof -i:80 #查看80端口被哪些进程占用，可以看到是httpd

重新启动，依旧失败

lsof -i:80却这是占用进程改变，再杀，并把httpd 关闭且不自动开启
systemctl stop httpd ，systemctl disable httpd

再开启，成功
