【问题描述】：

我已经使用 Spring Boot 设置了 logback。当我使用“mvn package”时，它会在 logback-spring.xml 中指定的指定位置创建日志文件然而，当我将战争部署到 Tomcat 管理器上时，我在 tomcat 日志文件中收到以下错误。

Tomcat 安装在 /opt/tomcat/apache-tomcat-version/ 我的日志文件目标是 /opt/tomcat/applogs/ 具有权限

drwxr-xr-x 9 tomcat tomcat 4096 Dec  8 14:02 apache-tomcat-9.0.70
drwxrwxrwx 2 tomcat tomcat 4096 Jan  2 19:35 applogs

我试过将 user:groups 更改为 {whoami}:{whoami}、root:root 等，但 tomcat 管理器不会启动 war 部署

FAIL - Application at context path [/springapp] could not be started
FAIL - Encountered exception [org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/springapp]]]

我知道已经创建的日志来自 spring boot，与 tomcat 无关，而且我也知道 tomcat 出于安全目的需要专门的用户，但此时我不知道该怎么做。

【解决方案1】：

您指定的日志目录权限不足，应用没有写入权限。

你可以使用chmod 777 dir给那个目录完全访问权限，或者在配置文件中指定一个有访问权限的目录
