當我們使用systemctl restart nginx 命令重啟服務時發現報錯如下:
Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.首先我們可以用 systemctl status nginx 查看當前nginx狀態
systemctl status nginx
● nginx.service - nginx - high performance web server
Loaded: loaded (/usr/lib/systemd/system/nginx.service; disabled; vendor preset: disabled)

Hint: Some lines were ellipsized, use -l to show in full.第一種方法: 我們發現埠被占用,使用命令查看被占用埠的行程:netstat -anltp | grep 80
查看到被占用的行程號 然后 kill -9 行程號 殺死行程之后繼續重啟
第二種方法:可能是我們在修改/etc/nginx/conf.d/default.conf或者是/etc/nginx/nginx.conf檔案時配置錯誤 ,重新檢查編輯,如果實在找不到錯誤,我們可以進入nginx的報錯日志進行查看:tail -f /var/log/nginx/error.log 根據nginx的報錯檔案可以進行相關的具體修改.
