# 升级apk-tools
apk upgrade --no-cache apk-tools
安装 rc-service 服务
Alpine使用的是OpenRCinit系统，而rc-service是openrc的一部分，所以安装openrc即可，使用如下命令安装：
apk add openrc --no-cache
管理服务
列出所有可用服务
rc-service --list
启动/停止/重启 已有服务
rc-service 服务名 start/stop/restart
OR
/etc/init.d/服务名 start/stop/restart
设置开机自启动
rc-update add {service-name}
启动openvpn报错
- 出现：* WARNING: openvpn is already starting或touch: /run/openrc/softlevel: No such file or directory问题
解决方案
sudo apk add --no-cache openrc
sudo openrc
sudo touch /run/openrc/softlevel
sudo rc-service openvpn start
- 出现 Note: Cannot open TUN/TAP dev /dev/net/tun: Permission denied (errno=13) Note: Attempting fallback to kernel 2.2 TUN/TAP interface Cannot open TUN/TAP dev /dev/tun0: No such file or directory (errno=2)
The TUN/TAP device is not set up by default on your VPS. Instructions will vary with your virtualization platform.
解决：
mkdir -p /dev/net
mknod /dev/net/tun c 10 200
chmod 600 /dev/net/tun
cat /dev/net/tun测试TUN/TAP设备是否可用：
如果您收到消息cat: /dev/net/tun: File descriptor in bad state您的 TUN/TAP 设备已准备好使用
如果您收到消息cat: /dev/net/tun: No such device the TUN/TAP 设备未成功创建```
