Systemctl 配置 Nginx 自启动显示超时

[RobertYang]

nginx.service 是这样编写的

    [Unit]
    Description=A high performance web server and a reverse proxy server
    After=network.target network-online.target nss-lookup.target

    [Service]
    Type=forking
    PIDFile=/usr/local/nginx/logs/nginx.pid
    PrivateDevices=yes
    SyslogLevel=err

    ExecStart=/usr/local/nginx/sbin/nginx -g 'pid /usr/local/nginx/logs/nginx.pid; error_log stderr;'
    ExecReload=/usr/local/nginx/sbin/nginx -s reload
    KillMode=mixed

    [Install]
    WantedBy=multi-user.target

开机后 Nginx 没有正确启动

    $ sudo systemctl status nginx
    * nginx.service - A high performance web server and a reverse proxy server
       Loaded: loaded (/usr/lib/systemd/system/nginx.service; enabled; vendor preset: disabled)
       Active: failed (Result: timeout) since Sat 2018-08-04 16:26:14 CST; 10s ago

    Aug 04 16:26:14 isthnew systemd[1]: Failed to start A high performance web server and a reverse proxy server.

系统是 Arch，nginx 版本 1.15.2，貌似很早之前就出现过了，但是没注意，开机后使用 sudo systemctl start nginx 来启动 nginx 一问题都没有。

仅作对比：

```
[Unit]
Description=A high performance web server and a reverse proxy server
Documentation=man:nginx(8)
After=network.target

[Service]
Type=forking
PIDFile=/usr/local/nginx/logs/nginx.pid
ExecStartPre=/usr/local/nginx/sbin/nginx -t -q -g 'daemon on; master_process on;'
ExecStart=/usr/local/nginx/sbin/nginx -g 'daemon on; master_process on;'
ExecReload=/usr/local/nginx/sbin/nginx -g 'daemon on; master_process on;' -s reload
ExecStop=-/sbin/start-stop-daemon --quiet --stop --retry QUIT/5 --pidfile /usr/local/nginx/logs/nginx.pid
TimeoutStopSec=5
KillMode=mixed

[Install]
WantedBy=multi-user.target
```

[MeteorCat]

手动编译，手动写 systemctl ？

[RobertYang]

@MeteorCat 是的

[RobertYang]

@wqyyy 替换了你写的这个也启动不了，systemd 显示启动时间超过 1min30s，然后显示错误

[cominghome]

看看 nignx error-log 和 system message，或者直接启动 nginx 试试排除 nginx 配置原因，nginx.service 就那两行，不一定是 systemctl 的问题

[Hardrain]

journalctl -xe -u nginx.service 的输出？

[wqyyy]

@RobertYang 这样子的话我也不知道了，这个是从 Ubuntu 源里拆出来之后略作修改的。

[RobertYang]

@cominghome @Hardrain nginx 日志没有记录到错误，journalctl 还是提示启动超时的那两行

[iUnix]

https://askubuntu.com/questions/953920/systemctl-service-timed-out-during-start

[RobertYang]

@iUnix 依然不工作，放弃了

[iUnix]

@RobertYang 手动 ok，我猜它启动时某些服务还没 ready，问题应该在 after 那里。

[iUnix]

@RobertYang 把启动顺序往后调看看是不是这个问题。

[henryshen233]

@iUnix 有些时候 ssh 上去就开了，默认开机不会打开，这种是什么原因呢

[iUnix]

@henryshen233 有没有日志？ systemctl 或者 nginx

[RobertYang]

@iUnix systemctl 日志就是 nginx.service: Start operation timed out. Terminating. nginx 未记录到日志。

[RobertYang]

@iUnix 刚刚看错楼了，我等下调到 after=php-fpm 后面试试

[RobertYang]

@iUnix 调到 php-fpm 之后启动时间依然超过 1 分 30 秒然后报错

好像权限问题～我以前也遇到过

[winterbells]

Nginx 默认的文件
Nginx 是手动编译的，用这个在 CentOS 和 Ubuntu 上都正常启动

[RobertYang]

@winterbells 同样不行，有点玄学了
