Solaris 各个level的解释

系统启动时，进入/etc/inittab中initdefault所定义的运行级别(deafult 3)各运行级别的定义： 
    

run level:

0, (halt, shotdown, stop+a,sync,go ) 
1, (single user, boot -s, init  s )
2, (multiuser, unshare net)
3, (multiuser, deafult)
5, (halt, power off )
6, (reboot to level 3 )
S  (init 1,  boot -s) 
 

改变系统运行级别命令:
# init 0, halt, shotdown, stop+a,sync,go 
# init 1, single user, boot -s, init  s 
# init 2, multiuser, unshare net 
# init 3, multiuser, deafult 
# init 5, halt, power off 
# init 6, reboot to level 3 
# init s, init 1,  boot -s 
# init *,shutdown,halt,poweroff, reboot -- -r, reboot -- -s  
       

ok> boot -s, boot -sra
