debian – Nginx init.d脚本

昨天在我的debian机器上进行了dist-upgrade后,我遇到了nginx init脚本的一些问题.每当我尝试使用init脚本启动nginx时,它会出现一条错误消息：

# service nginx start
Job for nginx.service failed. See 'systemctl status nginx.service' and 'journalctl -xn' for details.

systemctl status nginx.service的输出：

# systemctl status nginx.service
● nginx.service - A high performance web server and a reverse proxy server
   Loaded: loaded (/lib/systemd/system/nginx.service; enabled)
   Active: failed (Result: exit-code) since Tue 2015-05-19 12:36:12 CEST; 7s ago

  Process: 14126 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=203/EXEC)

journalctl -xn的输出：

我在init.d中的nginx文件：

nginx守护程序文件位于/usr/local/sbin / nginx(我在那里编译).

到目前为止我尝试过的事情：
我将守护进程文件/usr/local/sbin / nginx复制到/usr/sbin / nginx

当我使用服务nginx启动它挂起启动nginx.当我尝试连接到端口80时,它确实有效.所以我继续编辑我的init脚本并将PATH = /usr/local/sbin：/usr/local/bin：/ sbin：/ bin：/usr/sbin：/usr/bin更改为PATH = /usr/sbin：/ USR /斌：/ sbin目录：/ bin中：/usr/sbin目录：在/usr/bin中.然而,这给出了相同的结果.

到目前为止我还没有尝试过其他任何东西.

解决方法:

my nginx file in init.d:

……完全无关紧要.查看systemctl的输出.它告诉你究竟要查看的文件：

Loaded: loaded (/lib/systemd/system/nginx.service; enabled)

那是你的服务单位. systemctl告诉您该服务单元为准备启动服务而配置的内容：

 Process: 14126 ExecStartPre=/usr/sbin/nginx -t -q -g daemon on; master_process on; (code=exited, status=203/EXEC)

这就是您在服务单元的ExecStartPre设置中找到的内容.你会注意到PATH也完全不相关(在systemd中是设计的).期刊对发生的事情更加明确：

systemd[14126]: Failed at step EXEC spawning /usr/sbin/nginx: No such file or directory

无论您怎么想,计算机都认为在您尝试启动该服务时,/usr/sbin / nginx无法作为程序运行,因为该名称不存在任何文件.

我有根据的猜测是,您的服务单元中有一个RootDirectory设置,并且您将文件复制到不在更改的根环境中的/usr/sbin,或者从加载程序映像所需的某些辅助共享库中丢失了改变了根环境.
