nginx - 我的 NGINX 服务器已关闭。如何重新启动它？我对 NGINX 和 CentOS 还很陌生

Question

这是我的 NGINX 配置文件:

worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

    server {
        listen       80;
        server_name  localhost;
        location / {
            root  /usr/share/nginx/html;
            index  index.html index.htm;
        }
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

当我输入 service nginx start在我的终端中，它显示:

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.

当我执行 systemctl status nginx.service表明:

i install nginx in my remote server
但我在我的 nginx.conf 文件中犯了一些错误，无法恢复
所以它试图删除我的 nginx 并重新配置它
所以我使用链接中给出的这些步骤来删除我的 nginx

但是当我尝试sudo systemctl start nginx or [root@lotto nginx]# service nginx start它的显示

错误在您的配置文件中。我在编辑您的帖子时不小心更正了它，因为我认为您复制错误。

此行Jun 29 10:17:58 lotto nginx[21459]: nginx: [emerg] unexpected end of file, expecting "}" in /etc/ng...f:80准确地告诉你什么时候出错了。如果语法不正确，服务将不会启动。

添加 }到您的 nginx.conf 结尾文件，它应该可以工作。
