1 Ubuntu网络配置
1.1 主机名
修改主机名 和centos7一样 修改后永久生效
root@ubuntu:~# hostnamectl set-hostname ubuntu2004.waluna.top
root@ubuntu:~# cat /etc/hostname
ubuntu2004.waluna.top
root@ubuntu:~# hostname
ubuntu2004.waluna.top
root@ubuntu:~# echo $HOSTNAME
ubuntu
root@ubuntu:~# exit
logout
ubuntu@ubuntu:~$ sudo -i
root@ubuntu2004:~# echo $HOSTNAME
ubuntu2004.waluna.top1.2 网卡名称
默认ubuntu的网卡名称和centos7类似，如：ens33，ens38等
修改网卡名称为传统命名方式：
# 修改配置文件为下面形式
root@ubuntu2004:~# vim /etc/default/grub
GRUB_CMDLINE_LINUX="net.ifnames=0"
# 或者sed修改
root@ubuntu2004:~# sed -i.bak '/^GRUB_CMDLINE_LINUX=/s#"$#net.ifnames=0"#' /etc/default/grub
# 生效新的grub.cfg文件

官网文档：
https://ubuntu.com/server/docs/network-configuration
1.3.1 配置自动获取IP
网卡配置文件才用YAML格式，必须以/etc/netplan/xxx.yaml文件命名方式存放
可以每个网卡对应一个单独的配置文件，也可以将所有网卡都放在一个配置文件里

支持多网卡绑定七种模式
第一种模式: mod=0，即: (balance-rr) Round-robin policy(平衡抡循环策略）
特点:传输数据包顺序是依次传输〈即:第1个包走eth0，下一个包就走eth1...一直循环下去，直到最后一个传输完毕），此模式提供负载平衡和容错能力。
第二种模式: mod=1，即: (active-backup) Active-backup policy (主-备份策略）
特点:只有一个设备处于活动状态，当一个宕掉另一个马上由备份转换为主设备。mac地址是外部可见得，从外面看来，bond的MAc地址是唯一的，以避免switch(交换机)发生混乱。此模式只提供了容错能力;由此可见此算法的优点是可以提供网络连接的可用性，但是它的资源利用率较低，只有一个接口处于工作状态，在有N个网络接口的情况下，资源利用率为1/N.
第三种模式: mod=2，即:(balance-xor) xoR policy(平衡策略）
特点:基于指定的传输HASH策略传输数据包。缺省的策略是:(源MAc地址 XOR目标MAC地址）% slave数量。其他的传输策略可以通过xmit_hash_policy选项指定，此模式提供负载平衡和容错能力。
第四种模式: mod=3，即:broadcast（广播策略)
特点:在每个slave接口上传输每个数据包，此模式提供了容错能力。
第五种模式: mod=4，即:(802.3ad)IEEE 802. 3ad Dynamic link aggregation(IEEE802 .3ad动态链接聚合）
特点:创建一个聚合组，它们共享同样的速率和双工设定。根据802.3ad规范将多个slave工作在同一个激活的聚合体下。
必要条件:
条件1: ethtool持获取每个slave的速率和双工设定。
条件2: switch(交换机)支持IEEE 802.3ad Dynamic link aggregation.
条件3:多数switch(交换机)需要经过特定配置才能支持802.3ad模式。
第六种模式: mod=5，即: (balance-t1b) Adaptive transmit load balancing(适配器传输负载均衡）
特点:不需要任何特别的switch(交换机)支持的通道bonding。在每个slave上根据当前的负载〈根据速度计算〉分配外出流量。如果正在接受数据的slave出故障了，另一个slave接管失败的slave的MAC地址。该模式的必要条件:
ethtool支持获取每个slave的速率
第七种模式: mod=6，即: (balance-a7b) Adaptive load balancing(适配器适应性负载均衡)
特点:该模式包含了balance-tlb模式，同时加上针对IPV4流量的接收负载均衡(receive loadbalance, rlb)，而且不需要任何switch(交换机)的支持。
