# OVS编译

## 直接源码编译安装

```bash
export OVS_VERSION="2.6.1"
export OVS_DIR="/usr/src/ovs"
export OVS_INSTALL_DIR="/usr"
curl -sSl http://openvswitch.org/releases/openvswitch-${OVS_VERSION}.tar.gz | tar -xz && mv openvswitch-${OVS_VERSION} ${OVS_DIR}

cd ${OVS_DIR}
./boot.sh
# 如果启用DPDK，还需要加上--with-dpdk=/usr/local/share/dpdk/x86_64-native-linuxapp-gcc
./configure --prefix=${OVS_INSTALL_DIR} --localstatedir=/var --enable-ssl --with-linux=/lib/modules/$(uname -r)/build
make -j `nproc`
make install
make modules_install
```

更新内核模块

```bash
cat > /etc/depmod.d/openvswitch.conf << EOF
override openvswitch * extra
override vport-* * extra
EOF

depmod -a
cp debian/openvswitch-switch.init /etc/init.d/openvswitch-switch
/etc/init.d/openvswitch-switch force-reload-kmod
```

## 编译RPM包

```bash
make rpm-fedora RPMBUILD_OPT="--without check"
```

启用DPDK

```bash
make rpm-fedora RPMBUILD_OPT="--with dpdk --without check"
```

编译内核模块

```bash
make rpm-fedora-kmod
```

## 编译deb包

```bash
apt-get install build-essential fakeroot
dpkg-checkbuilddeps
# 已经编译过，需要首先clean
# fakeroot debian/rules clean
DEB_BUILD_OPTIONS='parallel=8 nocheck' fakeroot debian/rules binary
```

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://sdn.feisky.xyz/wang-luo-ji-chu/index-2/build.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
