ONOS一鍵安裝腳本
工欲善其事，必先利其器。在部署SDN實(shí)踐時(shí)，通常需要安裝OVS和控制器等軟件，經(jīng)歷過的同學(xué)都知道，很多時(shí)候會(huì)被一些細(xì)節(jié)卡住，影響生產(chǎn)效率。有時(shí)由于實(shí)驗(yàn)需要還需要多次部署同樣的內(nèi)容，重復(fù)進(jìn)行多遍同樣的命令，浪費(fèi)時(shí)間。所以很有必要將安裝過程轉(zhuǎn)化為一鍵安裝腳本。本文總結(jié)的一鍵安裝腳本就是在部署ONOS集群時(shí)，為提高安裝ONOS效率而整理的，希望能幫助到同樣需要多次安裝ONOS的其他人。
安裝腳本
安裝腳本將安裝ONOS及其依賴軟件的所有命令都寫到了shell文件，并加一些必要判斷語句，使得安裝腳本使用起來更加人性化。需要注意的是，此文件僅完成了ONOS的安裝，并沒有完成ONOS啟動(dòng)之前的配置，需要啟動(dòng)相關(guān)服務(wù)，還需手動(dòng)進(jìn)行配置。腳本內(nèi)容如下所示：
- sh
- #!/bin/bash
- #make sure only root can run our script.
- if [ "$(id -u)" != "0" ]; then
- echo "You need to be 'root' dude." 1>&2
- exit 1
- fi
- _version="1.0"
- echo "========================INSTALL ONOS======================="
- # Download and unzip apache-karaf
- if [ -d /root/Applications ]
- then
- cd /root/Applications
- else
- mkdir /root/Applications
- cd /root/Applications
- fi
- if [ -f apache-karaf-3.0.2.tar.gz ]
- then
- echo "apache-karaf-3.0.2.tar.gz has exist"
- else
- wget http://apache.fayea.com/karaf/3.0.2/apache-karaf-3.0.2.tar.gz
- tar -xzf apache-karaf-3.0.2.tar.gz
- fi
- # Download and install apache-maven
- if [ -f apache-maven-3.2.5-bin.tar.gz ]
- then
- echo "apache-maven-3.2.5.bin.tar.gz has exist"
- else
- wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.2.5/binaries/apache-maven-3.2.5-bin.tar.gz
- tar -xzf apache-maven-3.2.5-bin.tar.gz
- mv apache-maven-3.2.5 /usr/local/apache-maven
- # set environment
- echo "export M2_HOME=/usr/local/apache-maven" >> /etc/profile
- source /etc/profile
- echo "export PATH=$PATH:$M2_HOME/bin" >> /etc/profile
- source /etc/profile
- # in case of failure of setting environment
- export PATH=$PATH:$M2_HOME/bin
- fi
- # Install java-8-oracle
- if which java
- then
- echo "java-8 has been installed."
- else
- apt-get install python-software-properties
- sudo add-apt-repository ppa:webupd8team/java -y
- sudo apt-get update
- sudo apt-get install oracle-java8-installer oracle-java8-set-default -y
- # set JAVA_HOME
- echo "export JAVA_HOME=/usr/lib/jvm/java-8-oracle" >> /etc/profile
- source /etc/profile
- fi
- # show the info of java and maven to check.
- java -version
- mvn --version
- # Download ONOS
- if [ -d /home/onos ]
- then
- cd /home/onos
- else
- mkdir /home/onos
- cd /home/onos
- fi
- if which zip
- then
- echo "zip has been installed"
- else
- apt-get install zip
- fi
- if [ -f onos-$_version.zip ]
- then
- echo "onos-$_version.zip has exist"
- else
- wget https://github.com/opennetworkinglab/onos/archive/onos-$_version.zip
- unzip onos-$_version.zip
- # set environment of ONOS
- echo "export ONOS_ROOT=/home/onos/onos-onos-$_version" >> /etc/profile
- echo "export KARAF_ROOT=/root/Applications/apache-karaf-3.0.2" >> /etc/profile
- source /etc/profile
- source $ONOS_ROOT/tools/dev/bash_profile
- fi
- # Build ONOS
- cd onos-onos-$_version/
- mvn clean install
Note: 若需下載其他版本ONOS，直接修改下載源碼部分和ONOS_ROOT即可，無需修改Karaf，maven，java8等內(nèi)容。
初始化配置
在安裝完ONOS之后，還需要進(jìn)行一些必要的配置，才能啟動(dòng)運(yùn)行了制定服務(wù)的ONOS。需要編輯$KARAF_ROOT/etc/org.apache.karaf.features.cfg文件，腳本中即為/root/Applications/apache-karaf-3.0.2/etc/org.apache.karaf.features.cfg。在該文件中的featuresRepositories部分和featuresBoot部分分別添加如下內(nèi)容：
- Shell
- 12featuresRepositories：mvn:org.onosproject/onos-features/1.0.0/xml/features(逗號(hào)隔開，加到***即可)
- featuresBoot：onos-api,onos-core-trivial,onos-cli,onos-openflow,onos-app-fwd,onos-app-mobility,onos-gui
