java - 我在 ubuntu 18.4 中安装 tomcat 时遇到问题

Question

当我想更改目录的所有者时: base) merat@HP-Pavilion:/opt/tomcat$ sudo chgrp –R tomcat/opt/tomcat 我懂了: chgrp:无效组:'-R' 我之前添加了 tomcat 组和用户，但是当我运行此命令时: (base) merat@HP-Pavilion:/opt/tomcat$ id tomcat 我得到 id: 'tomcat': no such user 也适用于团体: (基础)merat@HP-Pavilion:/opt/tomcat$ 组 tomcat 我有组:'tomcat':没有这样的用户 当我再次添加它时: (基础)merat@HP-Pavilion:/opt/tomcat$ sudo groupadd tomcat 我得到:groupadd:组“tomcat”已经存在 我该如何解决这个问题？

Answer 1

groups shows you your groups and not all. You could list all groups for example like that:

getent group

If you added yourself to the group, you'll need to logout and login for the change to take effect.
