关于ubuntu:tomcatThe-selected-directory-in-not-a-valid-Tomcat-home

环境

• Linux/Ubuntu20.04LTS
• Visual Studio Code
• Tomcat9.0.48

异样

抉择的目录不是Tomcat的目录

The selected directory in not a valid Tomcat home

起因

tomcat的目录权限有余！

计划

1. 目录权限有余就目录的应用权限，进入到Tomcat的装置目录，这里的装置目录是/usr/local,775 为 rwxr-xr-x， -R 即目录下所有文件权限都一样

lauiji@lauiji-IdeaPad-15sIML-2020:/usr/local$ sudo chmod 755 -R apache-tomcat-9.0.48[sudo] lauiji 的明码： 

2. 查看权限

lauiji@lauiji-IdeaPad-15sIML-2020:/usr/local$ ll总用量 56...drwxr-xr-x  9 root root 4096 6月  29 18:04 apache-tomcat-9.0.48/

3. 进入到Tomcat的目录下执行运作，看是否能运行胜利,胜利运行则阐明当初的权限够了

lauiji@lauiji-IdeaPad-15sIML-2020:/usr/local/apache-tomcat-9.0.48/bin$ ./startup.shUsing CATALINA_BASE:   /usr/local/apache-tomcat-9.0.48Using CATALINA_HOME:   /usr/local/apache-tomcat-9.0.48Using CATALINA_TMPDIR: /usr/local/apache-tomcat-9.0.48/tempUsing JRE_HOME:        /usrUsing CLASSPATH:       /usr/local/apache-tomcat-9.0.48/bin/bootstrap.jar:/usr/local/apache-tomcat-9.0.48/bin/tomcat-juli.jarUsing CATALINA_OPTS:   Tomcat started.

如果没有批改端口号的话，即可通过浏览器拜访localhost:8080

4. 敞开服务

lauiji@lauiji-IdeaPad-15sIML-2020:/usr/local/apache-tomcat-9.0.48/bin$ ./shutdown.shUsing CATALINA_BASE:   /usr/local/apache-tomcat-9.0.48Using CATALINA_HOME:   /usr/local/apache-tomcat-9.0.48Using CATALINA_TMPDIR: /usr/local/apache-tomcat-9.0.48/tempUsing JRE_HOME:        /usrUsing CLASSPATH:       /usr/local/apache-tomcat-9.0.48/bin/bootstrap.jar:/usr/local/apache-tomcat-9.0.48/bin/tomcat-juli.jarUsing CATALINA_OPTS:   NOTE: Picked up JDK_JAVA_OPTIONS:  --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED

5. 在vscode 下从新抉择Tomcat的目录即可，/usr/local/apache-tomcat-9.0.48
