  man nice 的结果

  NAME
         nice - run a program with modified scheduling priority
  
  SYNOPSIS
         nice [OPTION] [COMMAND [ARG]...]
  
  DESCRIPTION
         Run  COMMAND  with  an  adjusted niceness, which affects process scheduling.  With no COMMAND, print the current niceness.  Niceness values
         range from -20 (most favorable to the process) to 19 (least favorable to the process).
  
         Mandatory arguments to long options are mandatory for short options too.
  
         -n, --adjustment=N
                add integer N to the niceness (default 10)

  
  

  The  full documentation for nice is maintained as a Texinfo manual.  If the info and nice programs are properly installed at your site, the
         command
  
                info coreutils 'nice invocation'

  
  

  我执行 nice -n -10 service httpd start   的结果为

  We are no longer a registered authentication agent.

  
  

  不过nice这个优先级修改的效果不明显，不要纠结了
