在 arch linux 中启动 tomcat7.service 时出错

运行的操作系统是 Arch Linux x86-64。我尝试tomcat7.service通过启动systemctl start tomcat7.service，但它抛出一条错误消息：

Job for tomcat7.service failed because the control process exited with error code.
See "systemctl status tomcat7.service" and "journalctl -xe" for details.

当我执行时systemctl status tomcat7.service，它显示以下消息：

● tomcat7.service - Tomcat 7 servlet container

如果我ls /usr/lib/jvm/default-runtime检查我是否有 Java 环境，它会显示：

bin  conf  demo  include  jmods  legal  lib  man  release

所以，目录存在。

可能会发生什么？谢谢

您需要将 java-8 或更早版本设置为默认 java 版本才能在 archlinux 上使用 tomcat。按照 arch wiki 指南安装正确的版本。https://wiki.archlinux.org/index.php/Java#Officially_supported_pa​​ckages

为此，请运行：

sudo archlinux-java set java-8-openjdk
