今天安装启动PHP时出现下面的错误：

[[email protected] etc]# /application/php/sbin/php-fpm

错误：

[03-Aug-2017 21:30:29] ERROR: failed to open error_log (/app/logs/php-fpm.log): No such file or directory (2)

[03-Aug-2017 21:30:29] ERROR: failed to post process the configuration

[03-Aug-2017 21:30:29] ERROR: FPM initialization failed

解决方法：

[[email protected] etc]# netstat -lntup | grep 9000

tcp        0      0 127.0.0.1:9000              0.0.0.0:*           LISTEN      12810/php-fpm

[[email protected] etc]# killall php-fpm

再次启动未报错

[[email protected] etc]# /application/php/sbin/php-fpm

[[email protected] etc]# ps -ef|grep php-fpm
