nginx: [alert] kill(5272, 15) failed (3: No such process) 启动不了,apache搞得鬼

1.启动

sudo nginx
Password:
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)

2.stop

sudo nginx -s stop
nginx: [alert] kill(5272, 15) failed (3: No such process)

通过nginx.conf 找 nginx.pid 位置, 然后删除

cat /usr/local/etc/nginx/nginx.conf | grep .pid
#pid        logs/nginx.pid;

然而找不到
找找找到了....
/usr/local/var/run/nginx.pid
查看下

cat /usr/local/var/run/nginx.pid
5272

与nginx: [alert] kill(5272, 15) failed (3: No such process) 碰头成功,
删除该ngix.pid文件,重启

然而不行

sudo nginx
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)

.......⚠️漫长百度.....

mac默认安装了apache，随机启动会占用80端口，导致nginx启动不了，需要关闭apache（httpd）服务，取消随机启动。

执行命令

查询80端口被谁占用了
sudo lsof -i:80

 sudo lsof -i:80
COMMAND    PID  USER   FD   TYPE             DEVICE SIZE/OFF NODE NAME
httpd       80  root    4u  IPv6 0x1cc38b1a603f3a93      0t0  TCP *:http (LISTEN)
httpd      251  _www    4u  IPv6 0x1cc38b1a603f3a93      0t0  TCP *:http (LISTEN)

关闭随机启动

sudo launchctl unload -w /System/Library/LaunchDaemons/org.apache.httpd.plist

就启动了
