在尝试为我的项目设置tomcat服务器时，我收到以下错误：请参阅下面的完整堆栈跟踪：

SEVERE: Cannot start server. Server instance is not configured.

可能出现的错误是什么？在我的服务器配置中，我使用“使用Tomcat安装”。我必须替换server.xml，context.xml，portal-ext.properties，catalina.xml以匹配我的项目规范;使用jdbc资源等。在此更改后，我发现此错误...

3 个答案:

答案 0 :(得分：3)

例外是找不到类。找到具有此类的库。

确保将所有必需的库（* .jar）放在WEB-INF / lib文件夹中。

答案 1 :(得分：0)

我有同样的问题。我的配置是RHEL 7.6，Tomcat 8.5.40。我正在使用脚本安装和更新Tomcat。初始安装后，我需要更新tomcat / conf目录下的一些文件。当我尝试重新启动tomcat时，我在catalina.out中不断得到以下内容：并且问题无法恢复：

WARNING: Unable to load server configuration from [/var/lib/tomcat/conf/server.xml]

事实证明，问题的原因是试图设置所有权和模式。我在做：

sudo chown -R tomcat:tomcat /var/lib/tomcat/conf
sudo chmod -R 600 /var/lib/tomcat/conf
sudo chmod -R 750 /var/lib/tomcat/conf/Catalina

如果我未以这种全面递归的方式设置权限。即使进行递归方式或手动方式的最终结果（所有权和模式）完全相同，一切也都很好。这很奇怪。我希望这可以帮助某人。我花了两天半的时间来解决这个问题。

答案 2 :(得分：-1)

某些配置文件必定已损坏。我遇到了这个问题并通过卸载并重新安装tomcat来修复它。我使用tomcat 7.但你可以使用与aby版本相同的命令

sudo apt-get purge tomcat7
sudo apt-get install tomcat7

现在，当您运行服务器时，它将在多个文件中显示写入或读取失败。只需给这些目录写入和读取权限

chmod -R a+r {directory_name}
chmod -R a+w {directory_name}

现在转到tomcat文件夹并在此处链接一些文件

cd /usr/share/tomcat7
sudo ln -s /var/lib/tomcat7/conf conf
sudo ln -s /var/log/tomcat7 log
sudo ln -s /etc/tomcat7/policy.d/03catalina.policy conf/catalina.policy
sudo chmod -R a+rwx /usr/share/tomcat7/conf

这将解决所有问题
