起因
最近在用proxmox做虛擬機,都是開機后就丟在一邊不管。但它的屏幕一直亮着,不會自動熄屏。網上查了些資料,都是用“setterm --blank 1”命令,是可以實現,重啟后又要進去輸一次太麻煩。想在登錄帳號前執行,用以下方法解決:
新建rc-local.service文件
添加以下內容。把下面命令全部復制到提示符中運行。它的vi快捷鍵與centos7中的有點不同,改用cat很方便
cat > /etc/systemd/system/rc-local.service <<EOF [Unit] Description=/etc/rc.local ConditionPathExists=/etc/rc.local [Service] Type=forking ExecStart=/etc/rc.local start TimeoutSec=0 StandardOutput=tty RemainAfterExit=yes SysVStartPriority=99 [Install] WantedBy=multi-user.target EOF
新建rc.local文件
proxmox找不到rc.local文件,自己新建一個。
cat > /etc/rc.local <<EOF #!/bin/sh -e # # rc.local # # This script is executed at the end of each multiuser runlevel. # Make sure that the script will "exit 0" on success or any other # value on error. # # In order to enable or disable this script just change the execution # bits. # # By default this script does nothing. # bash /root/bindip.sh setterm --blank 2 exit 0 EOF
上圖倒數第3行的命令中作用是兩分鍾后關屏幕
設置開機啟動
把這兩文件設置為開機啟動,當然要先添加權限,最后檢查它的狀態
chmod +x /etc/rc.local systemctl enable rc-local systemctl start rc-local.service systemctl status rc-local.service
可以看到圖片中Active:active (exited)……,說明成功了。
