背景:

私有云服务器 重启后php-fpm服务启动失败

报错：

[root@localhost php-fpm.d]# systemctl restart php-fpm.service

Job for php-fpm.service failed because the control process exited with error code. See "systemctl status php-fpm.service" and "journalctl -xe" for details.

查看systemctl status php-fpm

其中ERROR: **[/etc/php-fpm.d/www.conf:120] unknown entry ‘‘memcache.local’’**提示的错误是关键，

处理：

将www.conf的120行内容注释掉

然后重启成功！！
