Question

我有一个简单的nginx配置，语法正确。我使用厨师安装nginx，厨师脚本工作正常。

但是当我检查nginx的状态时，我发现它处于失败状态。如果我重新加载nginx，它会再次进入失败状态。 journalctl -xn 也不会产生太多错误，除了：

    [root@localhost vagrant]# journalctl -xn

[root@localhost vagrant]#

nginx -t成功，我在/var/log/nginx/errors.log中看不到任何内容

有没有其他方法可以解决为什么会失败？

systemctl status nginx.service都给出：

[root@localhost vagrant]# systemctl status nginx.service

systemctl cat nginx.service给出：

[root@virsinplatformapi02 sysadmin]# systemctl cat nginx.service
Unknown operation 'cat'.

我cd cd / lib / systemd / system并在nginx.service上执行cat：

[root@virsinplatformapi02 system]# cat nginx.service
[Unit]

After=network.target remote-fs.target nss-lookup.target

ExecStart=/opt/nginx-1.10.1/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]

如果我使用echo $ MAINPID，我什么也得不到。

那个单元文件不是很好。未设置类型，默认为simple，而您希望forking为nginx。这可能是错误$MAINPID值的原因。尝试使用official unit：

[Unit]
Description=The NGINX HTTP and reverse proxy server
After=syslog.target network.target remote-fs.target nss-lookup.target

[Service]
Type=forking
PIDFile=/run/nginx.pid
ExecStartPre=/opt/nginx-1.10.1/sbin/nginx -t
ExecStart=/opt/nginx-1.10.1/sbin/nginx
ExecReload=/bin/kill -s HUP $MAINPID
ExecStop=/bin/kill -s QUIT $MAINPID
PrivateTmp=true

[Install]
WantedBy=multi-user.target

您应该将其添加到/etc/systemd/system/nginx.service - 用于管理员创建的单位的目录，并具有优先权。
