1. 配置rc-local.service

ln -sf /lib/systemd/system/rc-local.service /etc/systemd/system/rc-local.service
echo "[Install]" >> /etc/systemd/system/rc-local.service
echo "WantedBy=multi-user.target" >> /etc/systemd/system/rc-local.service
echo "Alias=rc-local.service" >> /etc/systemd/system/rc-local.service

2. 配置rc.local

rc.local的内容根据自己需要进行修改

# cat /etc/rc.local
#!/bin/bash
rbd --user skywalking -p rbd-data map data-img2
mount /dev/rbd0 /data
# chmod a+x /etc/rc.local

3. 配置rc-local启动启动

# systemctl daemon-reload
# systemctl enable --now rc-local
Created symlink /etc/systemd/system/multi-user.target.wants/rc-local.service → /lib/systemd/system/rc-local.service.

4. 重启测试

ceph自动挂载了

# reboot
# root@skywalking-ui:~# df -Th
