Question

我有一个OpenSuse Linux，我安装了Tomcat 7.0.52，但是当我运行startup.sh时，总是没问题。我在localhost中运行nmap，但是没有出现tomcat服务和端口。

Starting Nmap 5.21 ( http://nmap.org ) at 2016-01-21 18:09 UYST 
Nmap scan report for localhost (127.0.0.1) Host is up (0.0000020s latency).

Nmap done: 1 IP address (1 host up) scanned in 0.08 seconds

当我运行shutdown.sh时，我收到了这条消息：

我的环境变量：

echo $JAVA_HOME
/opt/java/jdk1.8.0_65/

echo $JRE_HOME
/opt/java/jdk1.8.0._65/jre

出了什么问题？

Answer 1

您的环境变量定义中是否存在拼写错误？

echo $JAVA_HOME
/opt/java/jdk1.8.0_65/

echo $JRE_HOME
/opt/java/jdk1.8.0._65/jre

似乎后者JRE_HOME正在被使用并导致后面的错误情况：

/opt/java/jdk1.8.0._65/jre/bin/java

尝试重新定义JRE_HOME环境变量，如下所示：

export JRE_HOME='/opt/java/jdk1.8.0._65/jre/bin/java'

Tomcat 7无法启动
