linux下open-vswitch安装卸载操作

# 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

# apt install git

# git clone https://github.com/openvswitch/ovs.git（下载的git工程目录为~/ovs）

# ./boot.sh（在ovs工程根目录下）

# ./configure -with-linux=/lib/modules/$(uname -r)/build

# 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

export PATH=$PATH:/usr/local/share/openvswitch/scripts
# ovs-ctl start

# ovs-vsctl show
# ovs-vsctl add-br mybridge
# ovs-vsctl add-port mybridge eth0

# 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
