Der Server ist ausgefallen und Nginx kann nach langer Zeit nicht mehr hochfahren. Ich weiß nicht, was los ist. Bitte helfen Sie mir.

;listen string设置接受 FastCGI 请求的地址。可用格式为：'ip:port'，'port'，'/path/to/unix/socket'。每个进程池都需要设置。
listen = /dev/shm/php-cgi.sock
;listen.backlog int设置 listen(2) 的半连接队列长度。“-1”表示无限制。默认值：-1。
listen.backlog = -1
;listen.allowed_clients string设置允许连接到 FastCGI 的服务器 IPV4 地址。等同于 PHP FastCGI (5.2.2+) 中的 FCGI_WEB_SERVER_ADDRS 环境变量。仅对 TCP 监听起作用。每个地址是用逗号分隔，如果没有设置或者为空，则允许任何服务器请求连接。默认值：any。
listen.allowed_clients = 127.0.0.1
;listen.owner string如果使用，表示设置 Unix 套接字的权限。在Linux中，读写权限必须设置，以便用于 WEB 服务器连接。在很多 BSD 派生的系统中可以忽略权限允许自由连接。默认值：运行所使用的用户和组，权限为 0666。
;listen.owner = www

listen.owner = www
listen.group = www
listen.mode = 0660
user = www
group = www
;pm string
;设置进程管理器如何管理子进程。可用值：static，ondemand，dynamic。必须设置。
;static - 子进程的数量是固定的（pm.max_children）。
;ondemand - 进程在有需求时才产生（当请求时，与 dynamic 相反，pm.start_servers 在服务启动时即启动。
;dynamic - 子进程的数量在下面配置的基础上动态设置：pm.max_children，pm.start_servers，pm.min_spare_servers，pm.max_spare_servers。
pm = dynamic
;pm.max_children int pm 设置为 static 时表示创建的子进程的数量，pm 设置为 dynamic 时表示最大可创建的子进程的数量。必须设置。
;该选项设置可以同时提供服务的请求数限制。类似 Apache 的 mpm_prefork 中 MaxClients 的设置和 普通PHP FastCGI中的 PHP_FCGI_CHILDREN 环境变量。
pm.max_children = 50
;pm.start_servers int 设置启动时创建的子进程数目。仅在 pm 设置为 dynamic 时使用。默认值：min_spare_servers + (max_spare_servers - min_spare_servers) / 2。
pm.start_servers = 20
pm.min_spare_servers = 10
pm.max_spare_servers = 30
pm.max_requests = 500

这里的错误说得很清楚了
ExecStartPre是systemd启动服务前预执行的命令，通常用来检查配置或者设置环境变量
你这里指定了
/etc/nginx/nginx.conf作为nginx的配置文件，不过这个文件不存在，所以执行出错解决方法：
修改
/lib/systemd/system/nginx.service，把/etc/nginx/nginx.conf都改为/usr/local/nginx/conf/nginx.conf然后执行
systemctl daemon-reload && systemctl start nginx错误提示很明显，配置文件不存在
两者不在同一个位置：
需要在：/etc/nginx/nginx.conf
你的在：/usr/local/nginx/conf/nginx.conf
改成这样试试
/usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/vhost/www.yuming.com.conf
Nginx马上就挂了
