一. ovs 从源码编译安装:
安装依赖项:
# apt install make # apt install gcc # apt install build-essential # apt install libssl-dev # apt install libcap-ng-dev # apt install python2.7 # apt install python-pip # pip install six # apt install autoconf # apt install automake # apt install libtool
下载源码包
# apt install git # git clone https://github.com/openvswitch/ovs.git(下载的git工程目录为~/ovs)
生成配置文件
# ./boot.sh(在ovs工程根目录下)
配置
# ./configure -with-linux=/lib/modules/$(uname -r)/build
编译
# make # make install # make modules_install # config_file="/etc/depmod.d/openvswitch.conf" # for module in datapath/linux/*.ko; do modname="\$(basename \${module})" echo "override \${modname%.ko} * extra" >> "\$config_file" echo "override \${modname%.ko} * weak-updates" >> "\$config_file" done # depmod -a # /sbin/modprobe openvswitch # /sbin/lsmod | grep openvswitch
启动
export PATH=$PATH:/usr/local/share/openvswitch/scripts # ovs-ctl start
测试
# ovs-vsctl show # ovs-vsctl add-br mybridge # ovs-vsctl add-port mybridge eth0
二. Ovs的卸载
启动ovs之后,如果改动ovs源代码并且想更新ovs服务,进行如下操作:
# ovs-ctl stop 停止ovs服务 # ovs-dpctl show查看内核,会有一个ovs-system的datapath # ovs-dpctl del-dp ovs-system 删除上一步出现的datapath(不进行这一步,rmmod可能会报错) # rmmod openvswitch 卸载openvswitch内核模块,使用lsmod | grep openvswitch 没有openvswitch # 进入ovs源代码目录,按照前述编译步骤重新编译安装
