安装 OpenDayLight

ODL（OpenDayLight） 是常见、开源的 SDN 控制器，本文介绍如何在 Linux/CentOS 安装 OpenDayLight。

环境

• CentOS 7

安装依赖包：

yum install java-11-openjdk maven -y

配置 Java 环境变量到 /etc/profile：

export JAVA_HOME=/usr/lib/jvm/java-11-openjdk-11.0.10.0.9-1.el7_9.x86_64
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib
export PATH=${JAVA_HOME}/bin:$PATH

安装完成后验证：

$ java -version
openjdk version "11.0.10" 2021-01-19 LTS
OpenJDK Runtime Environment 18.9 (build 11.0.10+9-LTS)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.10+9-LTS, mixed mode, sharing)

安装

# 下载
wget https://nexus.opendaylight.org/content/repositories/opendaylight.release/org/opendaylight/integration/opendaylight/0.13.3/opendaylight-0.13.3.tar.gz

# 解压
tar -zxvf opendaylight-0.13.3.tar.gz
cd opendaylight-0.13.3

# 启动
./bin/start

# 检查状态
./bin/status

# 登入，密码为 karaf
./bin/client -u karaf

以上操作也可以使用如下命令登入：

./bin/karaf
Apache Karaf starting up. Press Enter to open the shell now...

安装插件

• rest api

opendaylight-user@root>feature:list -i
opendaylight-user@root>feature:install odl-restconf
opendaylight-user@root>feature:install odl-netvirt-openstack

安装 odl-netvirt-openstack 后：

• controller 默认监听在 6633
• manager 默认监听在 6640

管理 OpenvSwtich 配置参考

• 安装 Web UI 插件，仅在 0.3.x-Lithium 版本支持

opendaylight-user@root>feature:install odl-mdsal-apidocs
opendaylight-user@root>feature:install odl-l2switch-switch-ui
opendaylight-user@root>feature:install odl-mdsal-apidocs
opendaylight-user@root>feature:install odl-dluxapps-applications

扩展

ODL在也可以作为 neutron ML2 plugin 的 mechanism driver 和 OpenStack 集成，接管 neutron 对 OVS 进行控制。
