有些服务器安装Debian9/10开机网卡不自动开启,需要手动开启的时候可以修改rc.local达到开机自启动网卡效果;
Debian 9/10 默认不带 rc.local 文件,需要手动添加。
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
将ifup -a写入到rc.local文件
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.
ifup -a
exit 0
EOF
添加权限并设置开机自启;
chmod +x /etc/rc.local
systemctl enable rc-local
systemctl start rc-local.service
#检查状态
systemctl status rc-local.service
#返回Active:active信息,则成功。
