1、生成開機啟動 pm2 服務(wù)的配置文件
運行：pm2 startup 命令
pm2 startup

$ pm2 unstartup systemd
執(zhí)行
pm2 save
2、pm2 save, 保存當(dāng)前 pm2 運行的各個應(yīng)用保存到 /root/.pm2/dump.pm2下，開機重啟時讀取該文件中的內(nèi)容啟動相關(guān)應(yīng)用。
[root@xx ~]# pm2 save
[PM2] Saving current process list...
[PM2] Successfully saved in /root/.pm2/dump.pm2
3、查看配置是否開啟：使用命令systemctl status pm2-root.service文章來源：http://www.zghlxwxcb.cn/news/detail-519788.html
● pm2-root.service - PM2 process manager
