本篇承接上一篇 saltstack实现批量路由增加 ,在上一篇中提到了使用saltstack自带的network state实现了redhat路由的自动配置,不过在suse系统下却无解,晚上没事写了个模块,实现了针对suse系统实现路由增加。代码如下:
#coding: utf-8 # code from www.361way.com import commands __outputter__ = { 'suse': 'txt', } _SUSE_ROUTE_FILE = '/etc/sysconfig/network/routes' def init(): ywgw = __grains__['dcnyw']['ywgw'] yweth = __grains__['dcnyw']['yweth'] dcngw = __grains__['dcnyw']['dcngw'] dcneth = __grains__['dcnyw']['dcneth'] return ywgw,yweth,dcngw,dcneth def routing(): out = "" ywgw,yweth,dcngw,dcneth = init() if ywgw and yweth and dcngw and dcneth: r1 = "route add default " + ywgw r2 = "route add -net 10.0.0.0 netmask 255.0.0.0 gw " + dcngw r3 = "route add -net 200.200.0.0 netmask 255.255.0.0 gw " + dcngw r4 = "route add -net 10.211.6.0 netmask 255.255.255.0 gw " + ywgw r5 = "route add -net 10.125.0.0 netmask 255.255.0.0 gw " + ywgw out = commands.getoutput(r1 + '\n' + r2 +'\n' + r3 +'\n' + r4 +'\n' + r5) return out def suse(): if __grains__['os'] == 'SUSE': routing() ywgw,yweth,dcngw,dcneth = init() routestr = """default %s -- 10.0.0.0 %s 255.0.0.0 %s 10.125.0.0 %s 255.255.0.0 %s 10.211.6.0 %s 255.255.255.0 %s 200.200.0.0 %s 255.255.0.0 %s """ %(ywgw,dcngw,dcneth,ywgw,yweth,ywgw,yweth,dcngw,dcneth) f = open(_SUSE_ROUTE_FILE, 'w') f.writelines(routestr) f.close() cmd = 'netstat -A inet -rn |tail -n +3' return __salt__['cmd.run'](cmd) else: return 'OS not SuSE or can not get eth and gateway info!'
上面的代码需要注意,调用系统grains时,不能写在def函数体外,最开始我想将该定义写在函数体外,发现调用不成功,在minion端的/var/log/salt/minion日志中提示grains定义不存在。
具体执行效果见下图:
上面示例中只实了suse 路由这一个功能,如果不想使用系统自带的network.route state功能,也可以把redhat下的路由增加功能在该模块中写下。
