难以让 /etc/rc.d/init.d tomcat 启动脚本正常工作

难以让 /etc/rc.d/init.d tomcat 启动脚本正常工作

我有以下启动脚本,但在重新启动时不会启动 tomcat:

#!/bin/bash

echo 语句的输出是:

[root@server init.d]# cat /tmp/tomcatscript.out

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

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

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
