分别对应着0,1,3,5这几个运行级别，关于运行级别的官方解释如下（以红帽为例）：
# Default runlevel. The runlevels used by RHS are:
# 0 - halt (Do NOT set initdefault to this)# 1 - Single user mode# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)# 3 - Full multiuser mode# 4 - unused# 5 - X11# 6 - reboot (Do NOT set initdefault to this)在0,1,3,5这几个文件夹下面会找到“S99arcgisserver”文件，可见ArcGIS Server在服务器正常运行时都会随系统自动启动。
为了更详细的了解启动过程，我们来看一下文件内容：
