说明
在平时使用ovs中,经常用到的ovs命令,参数,与举例总结,持续更新中…
进程启动
1.先准备ovs的工作目录,数据库存储路径等
mkdir -p /etc/openvswitch
mkdir -p /var/run/openvswitch
1
2
2.先启动ovsdb-server
ovsdb-server /etc/openvswitch/conf.db
-vconsole:emer -vsyslog:err -vfile:info
--remote=punix:/var/run/openvswitch/db.sock
--private-key=db:Open_vSwitch,SSL,private_key
--certificate=db:Open_vSwitch,SSL,certificate
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --no-chdir
--log-file=/var/log/openvswitch/ovsdb-server.log
--pidfile=/var/run/openvswitch/ovsdb-server.pid
--detach --monitor

ps: 如果想清除配置,可以先删除/etc/openvswitch/*,然后再手动创建一个数据库:
ovsdb-tool create /etc/openvswitch/conf.db /usr/share/openvswitch/vswitch.ovsschema

3.初始化ovsdb
针对于新创建的数据库才需要初始化
ovs-vsctl --no-wait init

4.启动vswitchd进程
ovs-vswitchd unix:/var/run/openvswitch/db.sock
-vconsole:emer -vsyslog:err -vfile:info --mlockall --no-chdir
--log-file=/var/log/openvswitch/ovs-vswitchd.log
