如果不需要修改ONOS代码，只是像启动后和OVS连接一下，可以直接采用官方编译好的版本部署，下面是操作步骤的记录。

前期准备

• java放好

centec@ubuntu:/home$ ll
total 183872
drwxr-xr-x  4 root   root        4096 Aug 30 16:40 ./
drwxr-xr-x 24 root   root        4096 Aug 30 15:44 ../
drwxr-xr-x 19 centec centec      4096 Aug 30 17:01 centec/
drwxr-xr-x  8 root   root        4096 Jul 22 13:11 jdk1.8.0_144_oracle/
-rw-r--r--  1 root   root   188267912 Aug 30 16:40 jdk1.8.0_144_oracle.zip
centec@ubuntu:/home$ 

• 下载ONOS已经打包好的package,我下载的是1.10.3版本

sudo wget -c http://downloads.onosproject.org/release/onos-$ONOS_VERSION.tar.gz
}}
 * 放到/opt/下面并解压缩
{{{
centec@ubuntu:/opt$ ll
total 151968
drwxr-xr-x  4 root root      4096 Aug 30 16:23 ./
drwxr-xr-x 24 root root      4096 Aug 30 15:44 ../
drwxrwxrwx  8 root root      4096 Aug 30 16:47 onos/
-rw-r--r--  1 root root 155597235 Aug 30 16:23 onos-1.10.3.tar.gz
dr-xr-xr-x  4 root root      4096 Aug 30 14:15 vmware-tools-installer/
centec@ubuntu:/opt$ 
centec@ubuntu:/opt$ sudo mv onos-1.10.3/ onos/

• 修改karaf配置，重点是下面罗列的两行，其中java要和之前的目录保持一致

centec@ubuntu:/opt/onos/apache-karaf-3.0.8/bin$ sudo vi setenv

export JAVA_HOME=/home/jdk1.8.0_144_oracle/ # Location of Java installation
export KARAF_HOME=/opt/onos/apache-karaf-3.0.8 # Karaf home folder

使用并配置ONOS

启动onos

centec@ubuntu:/opt/onos/bin$ sudo /opt/onos/bin/onos-service start

• 结果发现openflow都没有装，CLI装回报错

onos> feature:install onos-providers-openflow-base 
Error executing command: Can't install feature onos-providers-openflow-base/0.0.0: 
Could not start bundle mvn:org.onosproject/onos-providers-openflow-device/1.10.3 in feature(s) onos-providers-openflow-base-1.10.3: Unresolved constraint in bundle org.onosproject.onos-providers-openflow-device [163]: Unable to resolve 163.0: missing requirement [163.0] osgi.wiring.package; (&(osgi.wiring.package=org.onosproject.net.optical.device)(version>=1.10.0)(!(version>=2.0.0)))
onos> 

• 打开网页，登陆用户名和密码依然是karaf/karaf,在application将openflow相关app安装

ONOS_GUI

• 确认已经安装

onos> feature:list | grep " x " | grep openflow
onos-providers-openflow-base          | 1.10.3           | x         | onos-providers-openflow-base-1.10.3          | OpenFlow Provider                                 
onos> 

• 好了，可以连上了

DUT214# show openflow controller status 
tcp:10.10.11.71:6653      role: master  status: online     online-time:    0d 0h12m50s    mgmt-if: yes    bind_ip: none
DUT214# 

• snoop一看，每个流表下发，都会加clear-action，而我们不支持，所以flow都没有下发成功

• 查看ONOS的源代码

[centec@CentOS7-11 impl]$ pwd
/home/centec/Applications/onos-1.10/core/common/src/main/java/org/onosproject/codec/impl
[centec@CentOS7-11 impl]$ 
[centec@CentOS7-11 impl]$ cat TrafficTreatmentCodec.java
if (treatment.clearedDeferred()) {
            result.put(CLEAR_DEFERRED, true);
        }
这里的true，应该改成false,就是无论如何都不加clear_actions这个instruction

• 上述修改可以编译成功，但是op的时候，报错

SHA cannot be verified

• 哪位帮忙验证一下吧
