Question

我正在大学的Ubuntu 18虚拟机上运行Apache Tomcat / 9.0.13。 Tomcat可以正常运行，并且已经在其上成功部署了Spring Boot项目。

现在，我尝试通过从官方网页下载.war文件并将其移至/ opt / tomcat / webapps文件夹在其上部署Jenkins。但是，当我尝试通过http://IP_ADRESS/jenkins访问它时，它显示以下错误：

Status Code: 500
Exception: Jenkins.instance is missing. Read the documentation of Jenkins.getInstanceOrNull to see what you are doing wrong.
Stacktrace:
java.lang.IllegalStateException: Jenkins.instance is missing. Read the documentation of Jenkins.getInstanceOrNull to see what you are doing wrong.

有人知道这个的原因/解决方案吗？

有同样的问题。请尝试安装其他库。就我而言，它有所帮助。（有关CentOS的说明）

yum install libfreetype.so.6
yum install freetype
yum install fontconfig

此外，某些问题可能与Java版本有关。请查看以下链接以获取详细信息：https://jenkins.io/blog/2018/06/17/running-jenkins-with-java10-11/
