Java Tomcat8显示“网页不可用”

我已经按照上面链接中的所有步骤设置了Tomcat8。直到我的url应该可用但不可用的部分。我已经检查了tomcat的状态。 第一 $netstat-nlp | grep8080

tcp        0      0 :::8080                     :::*                                  LISTEN      12621/java

其次，$ps-ef | grep tomcat

root     12030 11718  0 14:05 pts/0    00:00:00 su - tomcat8
tomcat8  12031 12030  0 14:05 pts/0    00:00:00 -bash
root     12246 12211  0 14:25 pts/1    00:00:00 su - tomcat8
tomcat8  12247 12246  0 14:25 pts/1    00:00:00 -bash
tomcat8  12621     1  4 15:00 pts/1    00:00:05 /home/tomcat8/jdk1.8.0_45/bin/java -Djava.util.logging.config.file=/home/tomcat8/apache-tomcat-8.0.21/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.endorsed.dirs=/home/tomcat8/apache-tomcat-8.0.21/endorsed -classpath /home/tomcat8/apache-tomcat-8.0.21/bin/bootstrap.jar:/home/tomcat8/apache-tomcat-8.0.21/bin/tomcat-juli.jar -Dcatalina.base=/home/tomcat8/apache-tomcat-8.0.21 -Dcatalina.home=/home/tomcat8/apache-tomcat-8.0.21 -Djava.io.tmpdir=/home/tomcat8/apache-tomcat-8.0.21/temp org.apache.catalina.startup.Bootstrap start

tomcat8  12675 12247  0 15:02 pts/1    00:00:00 grep tomcat

第三，$curl-I

我的雄猫在跑吗？如果是，为什么不显示url？我该怎么办

我正在运行linux redhat，使用jdk1.8.0_45和apache-tomcat-8.0.21

除非另有配置，否则部署的webapp sample.war应在以下位置可用：

---

http://localhost:8080/sample

您是否在tomcat中部署了任何Web应用程序？@frhd是的，我已经在CATALINA_主页/Web应用程序中添加了sample.war。如果没有重新配置，您应该打开路径http://localhost:8080/sample@frhd还是我应该把它放在索引所在的示例中？@frhd谢谢我刚刚得到它，你是对的，这是网络。对于与我有相同问题的其他人，请检查您是否已在防火墙中打开端口。如果您不知道如何打开，请单击我尝试的链接，但它显示无法访问网络现在显示此网页不再可用请查看tomcat日志文件，否则，这就像在完全黑暗的大海捞针。事实上，我已经在端口80上运行了apache 2.2，它会影响端口8080中的tomcat8吗？那应该没问题。这是另一个港口。
