Question

我正在尝试将简单的Web应用程序部署到我的centOs服务器（Digital Ocean）。跟着他们的向导，我设法设置了tomcat，设法登录经理，然后部署了我的战争。 Tomcat部署了它，它说好了，日志中没有任何错误。但是，当我点击应用程序链接时，它只显示找不到HTTP状态404 ..

在我的本地tomcat服务器上测试，同样的程序，工作得很好。

@SpringBootApplication
public class SuperiorniatletaApplication extends SpringBootServletInitializer{

    //JAR
    /*
     * public static void main(String[] args) {
     * SpringApplication.run(SuperiorniatletaApplication.class, args); }
     */


    //WAR

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(SuperiorniatletaApplication.class);
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(SuperiorniatletaApplication.class, args);
    }
}

检查MariaDb，它在本地端口3306上，尝试使用atleta_admin凭据登录，工作正常......我似乎无法找到问题，我认为它与CentOs本身有关？任何帮助将非常感激！谢谢！

尝试更改tomcat本身的文件权限但没有成功，还尝试上传我之前的项目，该项目已经处理了另一个具有相同结果的Droplet ..

似乎较新版本的tomcat限制了服务器本身的连接。不得不进去 /opt/tomcat/webapps/manager/META-INF/context.xml 并删除

<!--<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />-->

在上下文中。希望这有助于某人！
