What should I do if Linux cannot restart the php service?

Solution to the problem that root cannot start php-fpm in Linux:

centos 6.5 64-bit machine uses php-fpm installed with yum. Due to special reasons, php-fpm needs to be started with the root account, but it is found that it cannot be started.

1, modify user and group

# vim /etc/php-fpm.d/www.conf   
  
; RPM: apache Choosed to be able to access some dir as httpd  
user = root        //改为root  
; RPM: Keep a group allowed to write in log dir.  
group = root      //改为root

When restarting php-fpm, the following error is reported

ERROR: [pool www] please specify user and group other than root
[09-Jan-2015 16:54:26] ERROR: FPM initialization failed

Solution:

# /etc/init.d/php-fpm stop   //关闭php-fpm  
  
# nohup /usr/sbin/php-fpm -R >/dev/null 2>&1 &  
  
# echo "nohup /usr/sbin/php-fpm -R >/dev/null 2>&1 &" >> /etc/rc.local  //加入开机启动
