nginx启动失败

文章目录

在Windows安装了下nginx启动失败，报错nginx: [emerg] bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket in a way forbidden by its access permissions)

nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)

原来是nginx listen的80端口被占用

1、cmd输入命令netstat -aon|findstr “80”

打开cmd

输入命令: netstat -aon|findstr "80" 查询谁占了80端口

C:\Users\x1c>netstat -aon|findstr "80"
  TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       7532
  TCP    0.0.0.0:902            0.0.0.0:0              LISTENING       4780
  TCP    0.0.0.0:912            0.0.0.0:0              LISTENING       4780
  TCP    0.0.0.0:6800           0.0.0.0:0              LISTENING       10844
  TCP    0.0.0.0:8082           0.0.0.0:0              LISTENING       12892
  TCP    127.0.0.1:10808        0.0.0.0:0              LISTENING       13880

2.、查看80端口 7532对应的任务

输入命令： tasklist|findstr "7532"

C:\Users\x1c>tasklist|findstr "7532"
nginx.exe                     7532 Console                    1      7,440 K

原来是我之前打开过nginx程序占用了80端口，那就去关掉

3、结束对应任务

nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)

结束任务7532.

4、去启动nginx

打开cmd，去对应的nginx目录，启动nginx

nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)

浏览器输入localhost
nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)
启动成功

或者是 System 占用的80端口

C:\Users\x1c>netstat -aon|findstr "80"
  TCP    0.0.0.0:80             0.0.0.0:0              LISTENING       4
  TCP    0.0.0.0:902            0.0.0.0:0              LISTENING       4780
  TCP    0.0.0.0:912            0.0.0.0:0              LISTENING       4780
  TCP    0.0.0.0:6800           0.0.0.0:0              LISTENING       10844
  TCP    0.0.0.0:8082           0.0.0.0:0              LISTENING       12892
  TCP    127.0.0.1:6804         127.0.0.1:3462         TIME_WAIT       0
  TCP    127.0.0.1:10808        0.0.0.0:0              LISTENING       13880

这个有可能是 IIS服务 占用80端口 ，那就去尝试关闭IIS服务。

启动IIS服务 net start w3svc

关闭IIS服务 net start w3svc

以管理员身份运行cmd，

输入命令net start w3svc

nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)

关闭IIS服务了，那就可以去尝试启动下nginx，看是否是IIS占用了80端口
nginx启动失败（bind() to 0.0.0.0:80 failed (10013: An attempt was made to access a socket...permissions)

可以执行nginx.exe 那就是IIS占用了80端口。
