linux上安裝和解除安裝open-vswitch

一. ovs 從原始碼編譯安裝:

安裝依賴項:

# 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

下載原始碼包

# apt install git

# git clone https://github.com/openvswitch/ovs.git(下載的git工程為home/ovs)

生成配置檔案

# ./boot.sh(在ovs工程根目錄下)

配置

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

編譯

# 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

啟動

export PATH=$PATH:/usr/local/share/openvswitch/scripts

# ovs-ctl start

測試

# ovs-vsctl show

# ovs-vsctl add-br mybridge

# ovs-vsctl add-port mybridge eth0

二. Ovs的解除安裝

啟動ovs之後,如果改動ovs原始碼並且想更新ovs服務,進行如下操作:

# ovs-ctl stop 停止ovs服務

# ovs-dpctl show檢視核心,會有一個ovs-system的datapath

# ovs-dpctl del-dp ovs-system 刪除上一步出現的datapath(不進行這一步,rmmod可能會報錯)

# rmmod  openvswitch 解除安裝openvswitch核心模組,使用lsmod | grep openvswitch 沒有openvswitch

# 進入ovs原始碼目錄,按照前述編譯步驟重新編譯安裝
