@? 新建一個(gè)slave節(jié)點(diǎn)在Jenkins服務(wù)器上?????????????????????????????????????????????????
1,進(jìn)入Jenkins的主界面,進(jìn)入“Manage Jenkins” 頁(yè)面;
2,點(diǎn)擊如下圖中的“Manage? Nodes”:
3,進(jìn)入頁(yè)面后點(diǎn)擊“New Nodes”鏈接,直接選擇新建一個(gè)“Dumb Slave” 點(diǎn)擊保存即可;
4,配置剛剛新建的這個(gè)slave的相關(guān)信息,打開(kāi)這個(gè)slave進(jìn)入configuration界面:
上面中的只有一個(gè)需要強(qiáng)調(diào)了,就是“Launch method”,我們這里選擇的是 “Launch slave agent via java Web Start ”,這個(gè)方式建議在windows上使用最好。下面的介紹也是針對(duì)的這種launch模式的。
關(guān)于這個(gè)配置slave的詳細(xì)步驟如果需要的話可以在這個(gè)地方找到詳細(xì)的操作步驟:https://wiki.jenkins-ci.org/display/JENKINS/Step+by+step+guide+to+set+up+master+and+slave+machines? (這個(gè)可以說(shuō)是官方的最權(quán)限的guideline)。
這里推薦下:An easy way to control a Windows slave is by using Launch slave agents via Java Web Start? (Recommended for Windows)
#???? Slave遠(yuǎn)程機(jī)器的配置細(xì)節(jié)??????????????????????????????????????????????????????????????????
1,進(jìn)入需要控制的遠(yuǎn)程機(jī)器上,一定要進(jìn)入遠(yuǎn)程的slave機(jī)器,而不是你的master機(jī)器。輸入對(duì)應(yīng)的你的jenkins的地址,例如這里:
http://16.158.69.53:9999/jenkins/computer/
點(diǎn)擊進(jìn)入對(duì)應(yīng)的該slave機(jī)器的圖標(biāo)進(jìn)入:此時(shí)可能會(huì)報(bào)一些錯(cuò)誤,不用管。
點(diǎn)擊圖中的launch按鈕,他會(huì)提示你下載該文件slave-agent.jnlp.按照提示下載該文件,并保存在本地。我們這里需要確認(rèn)兩個(gè)問(wèn)題是否存在:
問(wèn)題一,確認(rèn)slave-agent.jnlp 是用javaws來(lái)運(yùn)行的,而不是java.exe 或者是javaw.exe來(lái)運(yùn)行,因?yàn)橐话愕臋C(jī)器默認(rèn)是采用java.exe啟動(dòng)的。我曾經(jīng)因?yàn)檫@個(gè)問(wèn)題折騰了好久。
問(wèn)題二,將slave-agent.jnlp用notepad打開(kāi)后,確認(rèn)其中的URL是可用的Jenkins地址。其中的配置可能是這樣的:
<jnlp spec="1.0+" codebase="http://16.158.69.53:9999/jenkins/computer/irshost12.tc.tb.com/">
<information>
<title>Slave Agent for irshost12.tc.tb.com</title>
<vendor>Jenkins project</vendor>
<homepage />
</information>
<security><all-permissions/></security>
<resources><j2se version="1.5+"/><jar /><property name="hudson.showWindowsServiceInstallLink" value="true"/>
</resources><application-desc main-class="hudson.remoting.jnlp.Main">
<argument>60c101541d377ad629da21b37c24cd6227edef74b97ff663c5b09e261ac2d5d6</argument><argument>irshost12.tc.tb.com</argument><argument>-url</argument>
<argument>http://16.158.69.53:9999/jenkins/</argument>
</application-desc>
</jnlp>
?
確認(rèn)其中的url地址是上面的正確的地址,而不是localhost,因?yàn)槲业膉enkins部署在本地測(cè)試。所以這里就遇到了顯示localhost的地址問(wèn)題。
之所以說(shuō)這個(gè)是因?yàn)檫@個(gè)是jenkins的一個(gè)bug:http://stackoverflow.com/questions/11287845/jenkins-slave-cant-get-started
Jenkins does not use the "Jenkins URL" setting for a lot of things, but establishing connection with Java Web Start slaves is one of them, so please ensure "Jenkins URL" in the master configuration is set correctly.
以上的配置完成后,如果點(diǎn)擊lanch按鈕,可能會(huì)報(bào)一下的錯(cuò)誤:
Slave irshost12.tc.tb.com
Connection was broken
java.net.SocketException: Connection reset at java.net.SocketInputStream.read(SocketInputStream.java:168) at java.io.BufferedInputStream.fill(BufferedInputStream.java:218) at java.io.BufferedInputStream.read(BufferedInputStream.java:237) at java.io.ObjectInputStream$PeekInputStream.peek(ObjectInputStream.java:2252) at java.io.ObjectInputStream$BlockDataInputStream.peek(ObjectInputStream.java:2545) at java.io.ObjectInputStream$BlockDataInputStream.peekByte(ObjectInputStream.java:2555) at java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1294) at java.io.ObjectInputStream.readObject(ObjectInputStream.java:348) at hudson.remoting.Command.readFrom(Command.java:92) at hudson.remoting.ClassicCommandTransport.read(ClassicCommandTransport.java:72) at hudson.remoting.SynchronousCommandTransport$ReaderThread.run(SynchronousCommandTransport.java:48)
Connect slave to Jenkins one of these ways:
-
Launch agent from browser on slave
-
Run from slave command line:
javaws http://16.158.69.53:9999/jenkins/computer/irshost12.tc.com.com/slave-agent.jnlp
-
Or if the slave is headless:
java -jar slave.jar -jnlpUrl http://16.158.69.53:9999/jenkins/computer/irshost12.tc.com/slave-agent.jnlp
?
如果出現(xiàn)上面的問(wèn)題,我們就不要在點(diǎn)擊launch按鈕起啟動(dòng)了,采用命令行去啟動(dòng)也是一樣的,命令行的命令上面已經(jīng)給出了:
命令1: javaws http://16.158.69.53:9999/jenkins/computer/irshost12.tc.com.com/slave-agent.jnlp
命令2: java -jar slave.jar -jnlpUrl http://16.158.69.53:9999/jenkins/computer/irshost12.tc.com/slave-agent.jnlp
?
運(yùn)行命令后,他會(huì)彈出一個(gè)界面:
?
如果上面的正常的話,過(guò)一會(huì)幾分鐘后,這個(gè)界面應(yīng)該就會(huì)變成下面的界面,就是多了一個(gè)File菜單,下拉這個(gè)File菜單就有一個(gè)選項(xiàng)他會(huì)提示你是否想設(shè)置為一個(gè)自啟動(dòng)的服務(wù)。可能將當(dāng)前的slave設(shè)置成一個(gè)服務(wù),每次機(jī)器重啟的時(shí)候都自動(dòng)啟動(dòng)slave服務(wù),這樣就不能每次都去啟動(dòng)這個(gè)slave agent了。
#???? Master Jenkins服務(wù)器端的配置細(xì)節(jié)?????????????????????????
如果上面的窗口中顯示Connected,可是一會(huì)有出現(xiàn)了Terminated的狀態(tài),那么很可能是因?yàn)槟愕膉enkins配置權(quán)限的時(shí)候沒(méi)有給匿名用戶啟動(dòng)slave的權(quán)限:http://stackoverflow.com/questions/14277512/problems-launching-the-slave-agent-via-java-web-start-on-jenkins
Two solutions seem to be coming up:
- Download the JNLP file (via browser, wget, curl, whatever) then run locally - may require extra parameters.
- Go to Manage Jenkins -> Configure Global Security, and under Project-based Matrix Authorization Strategy, enable “connect” in the “slave” section, for user “Anonymous”. This would leave you open to attack where someone emulates a slave (but in my case, on a private work network - that's not an issue.)
具體操作是進(jìn)入jenkins主界面,然后進(jìn)入Manage Jenkins -> Configure Global Security ,勾選其中的anonymous用戶的slave部分的權(quán)限。如下:
以上的就是配置遠(yuǎn)程機(jī)器作為slave的詳細(xì)步驟,如果又不太理解的,可以email我:alterhu2020@gmail.com 。
