我有以下启动脚本，但在重新启动时不会启动 tomcat：

有趣的是，如果我以 root 身份从终端运行它，请注意 CATALINA_BASE 是不同的目录：
[root@server init.d]# . /etc/init.d/functions
[root@server init.d]# daemon --user tomcat /users/tomcat/apache-tomcat-8.0.30/bin/startup.sh
Using CATALINA_BASE: /users/tomcat/apache-tomcat-8.0.30

Using CLASSPATH: /users/tomcat/apache-tomcat-8.0.30/bin/bootstrap.jar:/users/tomcat/apache-tomcat-8.0.30/bin/tomcat-juli.jar
Tomcat started.

Tomcat is not running
答案1
当我将 CATALINA_HOME 和 CATALINA_BASE 都更改为以下选项时，它现在可以正常工作：
#CATALINA_HOME is the location of the bin files of Tomcat
export CATALINA_HOME=/users/tomcat/apache-tomcat-8.0.30
#CATALINA_BASE is the location of the configuration files of this instance of Tomcat
export CATALINA_BASE=/users/tomcat/apache-tomcat-8.0.30
因此，对我而言有用的整个脚本如下所示：
#!/bin/bash
