Linux下安装好tomcat，shutdown.sh时报错解决

在云主机上安装tomcat，启动时显示如下：
/root/tomcat/apache-tomcat-9.0.0.M22/bin/startup.sh

Using CATALINA_BASE:   /root/tomcat/apache-tomcat-9.0.0.M22
Using CATALINA_HOME:   /root/tomcat/apache-tomcat-9.0.0.M22
Using CATALINA_TMPDIR: /root/tomcat/apache-tomcat-9.0.0.M22/temp
Using JRE_HOME:        /root/jdk/jdk1.8.0_131
Using CLASSPATH:       /root/tomcat/apache-tomcat-9.0.0.M22/bin/bootstrap.jar:/root/tomcat/apache-tomcat-9.0.0.M22/bin/tomcat-juli.jar
Tomcat started.

然而通过外网访问tomcat首页访问不到，我以为是端口问题，改了端口问题然后停止tomcat时遇到如下现象。
/root/tomcat/apache-tomcat-9.0.0.M22/bin/shutdown.sh

Using CATALINA_BASE:   /root/tomcat/apache-tomcat-9.0.0.M22

解决方法：
修改server.xml文件

vim /root/tomcat/apache-tomcat-9.0.0.M22/conf/server.xml

<Server port="8080" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.startup.VersionLoggerListener" />

将上边本来为8005改为你的tomcat端口号就OK了！！

测试成功：

[root@iz2ze93lv6g869fz1gl3zqz ~]# /root/tomcat/apache-tomcat-9.0.0.M22/bin/shutdown.sh
Using CATALINA_BASE:   /root/tomcat/apache-tomcat-9.0.0.M22
Using CATALINA_HOME:   /root/tomcat/apache-tomcat-9.0.0.M22
Using CATALINA_TMPDIR: /root/tomcat/apache-tomcat-9.0.0.M22/temp
Using JRE_HOME:        /root/jdk/jdk1.8.0_131
Using CLASSPATH:       /root/tomcat/apache-tomcat-9.0.0.M22/bin/bootstrap.jar:/root/tomcat/apache-tomcat-9.0.0.M22/bin/tomcat-juli.jar

此时也可以通过ip访问tomcat首页了： http://59.110.159.87:8080/
