zl	    zhaolong    xygroup  	可以	      zl123456

wz thirdUser 无额外支持 不可以 wz123456

[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# groups

多人在同一文件夹下进行项目开发，但这三个用户还是拥有自己的家目录与基本的私有群组，假设这个项目计划在/srv/projecta

zla	     zhaolonga          projecta  	可以	      zl123456a
wza	     wuzhenga	        projecta 	可以	      wz123456a

[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# su hxs
[hxs@iZ2zeg4tkk4ub8wept0hrjZ root]$ groups
hxs xygroup
[hxs@iZ2zeg4tkk4ub8wept0hrjZ root]$ exit
exit
[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# groupadd projecta
[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# useradd -G projecta -c "hanxiaoshuna" hxsa
[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# useradd -G projecta -c "zhaolonga" zla
[root@iZ2zeg4tkk4ub8wept0hrjZ ~]# useradd -G projecta -c "wuzhenga" wza
