启动失败nginx HTTP和反向代理服务器问题

Question

我第一次在我的fedora 24中安装nginx服务器。我使用apache服务器进行开发。仅为office集成，我必须安装nginx服务器。我安装nginx服务器使用这个命令dnf install nginx

在启动nginx服务器之前，我停止了apache并像下面这样禁用了它。

systemctl stop httpd
systemctl disable httpd

如果我启动nginx服务器sudo service nginx start，我得到以下错误。

Redirecting to /bin/systemctl start  nginx.service
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

所以我运行systemctl status nginx.service命令来了解问题的细节，我在我的终端得到以下输出。

[root@localhost ~]# systemctl -l status nginx.service

我尝试了几种方法来解决通过改变listen 80 listen 801在/etc/nginx/nginx.conf，但没有问题。我遵循下面的网址也，但我无法解决这个问题。

nginx not started and can't start

/etc/nginx/default.d/phpMyAdmin.conf

# phpMyAdmin
location = /phpMyAdmin {
    alias /usr/share/phpMyAdmin/;
}
location /phpMyAdmin/ {
     root /usr/share;
     index index.php index.html;
     location ~ ^/phpMyAdmin/(.+.php)$
     {
         try_files $uri =404;
         fastcgi_intercept_errors on;
         include        fastcgi_params;
         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
         fastcgi_pass   php-fpm;  //this is line number 17
     }
}

Answer 1

在我的例子中，这是因为80端口已被占用。

sudo lsof -t -i:80
sudo kill [port in reply]

Answer 2

我也遇到了这个问题，我有一个不同的情况，我确信在我运行这个命令后，我的机器上没有占用端口80:netstat -nplt .

我关闭Selinux服务后，问题解决了。

暂时关闭Selinux服务，您应该运行以下命令:

setenforce 0

永久禁用此服务:

vim /etc/selinux/config
Change item from `SELINUX=enforcing` to `SELINUX=disabled`

Answer 3

回答@mattdm建议的问题，我安装了php-fpm，现在它开始工作了。

sudo dnf install php-fpm

Answer 4

如果您已经安装了php-fpm，您应该查找套接字运行的位置并更改这一行fastcgi_pass php-fpm; //this is line number 17。

您应该能够在php-fpm池的配置文件中的listen行中找到它。例如，在Ubuntu中，你可以在/etc/php/<version>/fpm/pool.d/www.conf找到它。

你可能可以通过以下命令得到配置的线索:ps aux | grep php-fpm .
