opensuse初始化网络配置

opensuse:/etc/sysconfig/network # cat ifcfg-ens18
IPADDR='10.3.23.235/22'
BOOTPROTO='static'
STARTMODE='auto'
ZONE=public

opensuse:/etc/sysconfig/network # vim routes 
opensuse:/etc/sysconfig/network # cat routes 
default 10.3.23.254

/etc/sysconfig/network/config
定义如下三个变量 ：
NETCONFIG_DNS_STATIC_SEARCHLIST
NETCONFIG_DNS_STATIC_SERVERS
NETCONFIG_DNS_FORWARDER

重启网卡后会反写到/etc/resolv.conf中，如下图

opensuse:/etc/sysconfig/network # cat /etc/resolv.conf
### /etc/resolv.conf is a symlink to /var/run/netconfig/resolv.conf
### autogenerated by netconfig!
#
# Before you change this file manually, consider to define the
# static DNS configuration using the following variables in the
# /etc/sysconfig/network/config file:
#     NETCONFIG_DNS_STATIC_SEARCHLIST
#     NETCONFIG_DNS_STATIC_SERVERS
#     NETCONFIG_DNS_FORWARDER
# or disable DNS configuration updates via netconfig by setting:
#     NETCONFIG_DNS_POLICY=''
#
# See also the netconfig(8) manual page and other documentation.
#
### Call "netconfig update -f" to force adjusting of /etc/resolv.conf.
