一行实现
ps -ef |grep php-fpm |awk '{print $2}'|xargs kill -USR2
分步操作
1. ps -ef | grep php-fpm
ps -ef | grep php-fpm
www 40762 40761 0 17:30 ? 00:00:00 php-fpm: pool www
www 40763 40761 0 17:30 ? 00:00:00 php-fpm: pool www
www 40764 40761 0 17:30 ? 00:00:00 php-fpm: pool www
www 40765 40761 0 17:30 ? 00:00:00 php-fpm: pool www
www 40766 40761 0 17:30 ? 00:00:00 php-fpm: pool www
www 40767 40761 0 17:30 ? 00:00:00 php-fpm: pool www
2. kill -USR2 40767
3. 再次查看php-fpm的进程就发现进程编号已变
