异样

The selected directory in not a valid Tomcat home

起因

tomcat 的目录权限有余！

计划

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：

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/

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

如果没有批改端口号的话，即可通过浏览器拜访 localhost:8080
