我在大学的 Ubuntu 18 虚拟机上运行 Apache Tomcat/9.0.13。 Tomcat 运行没有问题，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 文件并将其移动到/opt/tomcat/webapps 文件夹来在其上部署 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？
最佳答案
遇到了同样的问题。请尝试安装额外的库。就我而言，它有所帮助。 (CentOS 使用说明)
yum install libfreetype.so.6
yum install freetype
yum install fontconfig
此外，一些问题可能与 java 版本有关。详情请查看以下链接:https://jenkins.io/blog/2018/06/17/running-jenkins-with-java10-11/
关于java - Jenkins 无法在 Tomcat 9 上运行，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53285291/
