伺服器重啟後 啟動php-fpm報錯：

[[email protected] bin]# /etc/init.d/php-fpm start
Starting php-fpm [11-Jun-2018 11:26:20] ERROR: unable to bind listening socket for address ‘127.0.0.1:9000’: Address already in use (98)
[11-Jun-2018 11:26:20] ERROR: FPM initialization failed
failed
9000埠被佔用

1檢視是否php-fpm 處於開啟狀態，伺服器並未殺死php-fpm的程序。

netstat -lntup | grep 9000

2 停止原來php-fpm的程序，重啟開啟

[[email protected] ~]# killall php-fpm
[[email protected] ~]# /etc/init.d/php-fpm
