Serv00服务器后台通过devil命令管理，常用功能收集：

  • 开启用户程序或脚本执行权限

    devil binexec on

  • 端口管理

    • 添加端口：

      devil port add [tcp,udp] 54321 # 指定端口
devil port add [tcp,udp] random # 随机分配端口

    • 查看端口：

      devil port list

    • 删除端口：

      devil port del [tcp,udp] 33333

  • 网站管理

    • 添加网站：

      devil www add xxx.your.domain proxy localhost 54321 # 代理到本地服务
devil www add xxx.your.domain [php] # php
devil www add xxx.your.domain pointer www.baidu.com
devil www add xxx.your.domain [python|nodejs|ruby] /home/xxxx/bin/xxx [production, staging, development, test]

    • 查看网站：

      devil www list

    • 删除站点：

      devil www del xxx.your.domain

  • 查看当前所在服务器IP

    devil vhost list

Ubuntu 22.04.1默认采用systemd-resolved作为DNS维护服务，其生成的/etc/resolv.conf文件内容如下：

# This is /run/systemd/resolve/resolv.conf managed by man:systemd-resolved(8).
# Do not edit.
#
# This file might be symlinked as /etc/resolv.conf. If you're looking at
# /etc/resolv.conf and seeing this text, you have followed the symlink.
#
# This is a dynamic resolv.conf file for connecting local clients directly to
# all known uplink DNS servers. This file lists all configured search domains.
#
# Third party programs should typically not access this file directly, but only
# through the symlink at /etc/resolv.conf. To manage man:resolv.conf(5) in a
# different way, replace this symlink by a static file or a different symlink.
#
# See man:systemd-resolved.service(8) for details about the supported modes of
# operation for /etc/resolv.conf.

如果需要修改DNS服务器，则修改文件/etc/systemd/resolved.conf中的DNS字段，示例:

#  This file is part of systemd.
#
#  systemd is free software; you can redistribute it and/or modify it under the
#  terms of the GNU Lesser General Public License as published by the Free
#  Software Foundation; either version 2.1 of the License, or (at your option)
#  any later version.
#
# Entries in this file show the compile time defaults. Local configuration
# should be created by either modifying this file, or by creating "drop-ins" in
# the resolved.conf.d/ subdirectory. The latter is generally recommended.
# Defaults can be restored by simply deleting this file and all drop-ins.
#
# Use 'systemd-analyze cat-config systemd/resolved.conf' to display the full config.
#
# See resolved.conf(5) for details.

再重启服务生效：
