无法启动 tomcat.service：未找到单元 tomcat.service

无法启动 tomcat.service：未找到单元 tomcat.service

我似乎无法以普通用户身份运行 tomcat 服务，当我以 root 身份尝试时，我得到了

root@ip-:/home/ubuntu# service tomcat
Run as /etc/init.d/tomcat <start|stop|restart>
root@ip-:/home/ubuntu# service tomcat start
Failed to start tomcat.service: Unit tomcat.service not found.
root@ip-:/home/ubuntu#

我确实手动运行了它，它似乎有效

root@ip-:/home/ubuntu# /etc/init.d/tomcat start
Using CATALINA_BASE:   /usr/local/tomcat/current_tomcat
Using CATALINA_HOME:   /usr/local/tomcat/current_tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/current_tomcat/temp
Using JRE_HOME:        /usr/local/java/current_java
Using CLASSPATH:       /usr/local/tomcat/current_tomcat/bin/bootstrap.jar:/usr/local/tomcat/current_tomcat/bin/tomcat-juli.jar

Tomcat started.

如果我以普通用户身份运行它，我似乎无法获得权限。我有一些用户没有密码，只有 ssh 密钥。

ubuntu@ip-:~$ service tomcat start

ubuntu@ip-:~$

这是服务脚本

ubuntu@ip-:~# cat /etc/init.d/tomcat 
#!/bin/bash
export CATALINA_HOME=/usr/local/tomcat/current_tomcat`
start() {
 sh $CATALINA_HOME/bin/startup.sh
}
stop() {
 sh $CATALINA_HOME/bin/shutdown.sh
}
case $1 in
  start|stop) $1;;
  restart) stop; start;;
  *) echo "Run as $0 <start|stop|restart>"; exit 1;;
esac
ubuntu@ip-:~# ll /etc/init.d/tomcat 
-rwxr-xr-x 1 root root 306 Feb 14 07:20 /etc/init.d/tomcat*

我在使用 Ubuntu 16.04 时遇到了这个问题。我已经解决了。

首先，在脚本顶部添加一行：

. /lib/lsb/init-functions

然后在 shell 中，创建从 /etc/rc* 到我的脚本的符号链接：

sudo update-rc.d tomcat defaults 95

这也将使您的脚本在重启后自动运行。
