error:
Linux下启动和关闭tomcat报错,如下图所示:
Neither the JAVA_HOME nor the JRE_HOME environment variable is defined 完美解决(tomcat error)

SSH: EXEC: completed after 201 ms

ERROR: Exception when publishing, exception message [Exec exit status not zero. Status [1]]
Build step 'Send build artifacts over SSH' changed build result to UNSTABLE
Finished: UNSTABLE

原因:

因为启动tomcat会调用tomcat安装文件中的startup.bat,而它调用了catalina.bat则调用了setclasspath.bat。因此需要在setclasspath.bat的开头手动声明环境变量。

解决方案:

用vim打开tomcat的bin目录下的setclasspath.sh,添加JAVA_HOME和JRE_HOME两个环境变量(下图红色方框内),两个环境变量路径为您安装的java JDK的路径。

windows下将export改为set即可。

保存并且退出即可。

再次使用service tomcat start没报错,如下图所示

成功用service tomcat start开启tomcat服务。
