在Ubuntu上配置Tomcat日志记录，可以通过修改Tomcat的配置文件来实现。以下是详细的步骤：
如果你还没有安装Tomcat，可以使用以下命令进行安装：
sudo apt update sudo apt install tomcat9 Tomcat的主要配置文件位于/etc/tomcat9/目录下。主要的日志配置文件是server.xml和logging.properties。
server.xml：用于配置Tomcat服务器的基本设置，包括端口、连接器等。logging.properties：用于配置Tomcat的日志记录。server.xml打开/etc/tomcat9/server.xml文件：
sudo nano /etc/tomcat9/server.xml 找到以下部分并确保它们正确配置：
<Server port="8005" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.startup.VersionLoggerListener" /> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" /> <GlobalNamingResources> <!-- Editable user database that can also be used by Tomcat's manager app and other web apps. If you want to use the user database for Tomcat-only purposes, set "developedOnly" attribute to true and don't change "resource" above. --> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" resource="UserDatabase"/> </GlobalNamingResources> <Service name="Catalina"> <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Engine name="Catalina" defaultHost="localhost"> <Realm className="org.apache.catalina.realm.LockOutRealm"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> </Realm> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> <!-- SingleSignOn valve, share authentication between web applications Documentation at: /docs/config/valve.html --> <!-- <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> --> <!-- Access log processes all example. Documentation at: /docs/config/valve.html To enable logging remove the <Comment> tags around this element --> <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" prefix="localhost_access_log" suffix=".txt" pattern="%h %l %u %t "%r" %s %b" /> </Host> </Engine> </Service> </Server> logging.properties打开/etc/tomcat9/logging.properties文件：
sudo nano /etc/tomcat9/logging.properties 你可以根据需要修改日志级别和输出位置。例如，将所有日志级别设置为FINE：
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = FINE org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = java.util.logging.ConsoleHandler java.util.logging.ConsoleHandler.level = FINE java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter 修改配置文件后，需要重启Tomcat以使更改生效：
sudo systemctl restart tomcat9 检查/var/log/tomcat9/目录下的日志文件，确保日志记录正常工作。
通过以上步骤，你应该能够成功配置Ubuntu上的Tomcat日志记录。根据需要，你可以进一步自定义日志格式和输出位置。
