# 检查配置文件语法:在重载或重启 Nginx 之前,必须确保配置文件语法正确,避免因错误配置导致服务无法启动。使用以下命令检查:
sudo nginx -t

# 输出示例
# nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
# nginx: configuration file /etc/nginx/nginx.conf test is successful
# 如果看到类似上述的成功提示,则表示配置语法正确,可以继续下一步。如果出现错误信息(如failed或err

# 平滑重启会在不中断现有连接的情况下加载新配置,适用于生产环境

sudo nginx -s reload

#或者

sudo systemctl reload nginx

# 检查服务状态
sudo systemctl status nginx
