Jenkins: 基礎篇（環境配置）
自動化領域比較有影響力的開源框架jenkins，確實比較強大，易用。不少公司將其用來作持續即成CI(continuous integration)。爲了拓展和強化本身的軟件設計生態系統，也將好久前使用過的jenkins再熟悉一下。在這裏作下備忘。java
首先就是下載jenkins安裝包，其實所謂的安裝，是習慣說法，這個直接從官網下載後，一個war包（jenkins.war， 60M大小左右），直接就能夠啓動運行。我本地安裝的是最新版本1.644. 因爲jenkins是java寫的，運行過程當中須要有JDK，即java要先安裝且配置好JAVA_HOME。linux
查看下個人java home信息：git
1 [root@CloudGame jenkins]# echo $JAVA_HOME 2 /usr/java/jdk1.8.0_65
這個基本要求具有後，就能夠啓動jenkins了，這裏演示，就直接java -jar jenkins.war來啓動，固然，jenkins也能夠在任何servlet容器裏面運行，好比Tomcat等。web

之因此能夠直接java -jar jenkins.war運行，從這個啓動日誌中能夠看到，是由於jenkins內部集成了jetty這個web服務程序，正如spring-boot的框架，默認集成Tomcat服務程序同樣。spring
jenkins的啓動後，默認http://localhost:8080就能夠打開查看web UI了，易用就體如今全部的相關配置都在web ui上完成。免除對命令行不習慣的用戶的煩惱，也不須要這裏配置一點，哪裏配置一點的腦裂痛苦。還有，也能夠本身設置選定的端口號，這樣就能夠： java -jar jenkins.war --httpPort=8081 , jenkins有不少啓動配置選項，能夠經過--help查看：apache

下面，打開瀏覽器看看效果吧：windows
這裏，是我測試用的一個環境，裏面有意個mueas的project，這個項目以前都是手動操做build，如今，但願用jenkins來定時操做build。瀏覽器
我會將這個項目刪除掉，而後新建一個，演示這個操做過程。刪除job，貌似web ui上沒有喲，這個其實也很簡單，在jenkins的默認運行環境路徑下，將其刪除便可（～/.jenkins/jobs），刪除後，須要從新啓動jenkins。否則web ui上還會有記錄，這個多是緩存裏面的數據吧。下面，將mueas job刪除，從0開始說說基本的配置，因爲我這個mueas項目是基於maven的，因此，我就以這個爲例子，作介紹。緩存
1 [root@CloudGame .jenkins]# cd jobs/ 2 [root@CloudGame jobs]# ll 3 total 4 4 drwxr-xr-x 4 root root 4096 Jan 20 13:01 mueas 5 [root@CloudGame jobs]# rm -rf mueas/
如今說配置的事情。個人mueas項目，是用git這個SCM工具管理的，因此，在jenkins裏面，須要安裝git的插件。jenkins的插件管理很是牛叉啊，現有的插件都有200多個，根據須要，本身選擇安裝，不須要的還能夠uninstall。在jenkins>Manage Jenkins>Manage Plugins>Available下面搜索須要的插件，爲了方便後續繼續使用，我將git, git-client,git-server都安裝了，還有一個GitHub的插件，這個也能夠勾上。安裝完後，須要重啓喲，這個是jenkins的特色，是否是有點像windows安裝應用程序後要重啓os的感腳。。。因爲我已經安裝了，我就將安裝了的tab頁相關信息截圖參考一下吧。session
先說下，這個是刪除掉以前的mueas job後重啓完成的界面，因爲一個job都沒有，提示是否建立job。這是後話。這裏主要是說從如何找到plugin的安裝頁面。下圖展現我已經安裝了的插件，這裏有些是jenkins默認就安裝的，紅色框的是我安裝的git相關的插件。徹底能夠根據本身項目須要選擇安裝。
除了上面紅色的框，發現沒，maven的集成插件也有，若沒有，也須要本身安裝maven插件的。再說說這個綠色的框，裏面有的後面有Downgrade信息的按鈕，這個是針對插件更新用的，這個更新是向低版本更新喲。
須要的插件安裝完了，那麼，就要說說系統環境配置了。以下圖所示，也很容易找到Jenkins>Manage jenkins>Configure System
這裏說說，最基本的配置信息吧，其餘的都採用jenkins默認的配置。須要配置的，以下圖，紅色框選部分，另外，JDK以及Maven安裝信息，要根據本身的系統環境進行配置。個人JDK以及Maven安裝路徑分別是：/usr/java/jdk1.8.0_65和/usr/local/apache-maven-3.3.3（其餘部分的信息，是系統自動填上的，就讓其存在吧，有的是必要的，有的是沒有用的，對我這個項目來講）：
上面顯示的就是主要要配置的，配置好後，點擊保存便可。
下面進入job的建立了，這裏才進入主題喲，呵呵，其實，真正的項目開發中，不少設置環境或則平臺搭建的這種不能直接體現出經濟效益的事情，更能反映出一個技術人員的功底。廢話哈！
而後進一步作配置，下面作詳細的配置，主要是git相關的配置。我選擇的源碼管理工具是git，配置URL，這個就是咱們在linux下作clone用的那個url，如出一轍，由於jenkins運行的時候也是要從遠程repo上clone待build的project。另一個很重要的配置，就是下面的credential了，這個估計很容易搞錯。
那麼就說說這個credential的配置，看下圖，我在Kind下拉框中選擇的是SSH Username with private key，由於咱們的git倉庫，採用的是SSH key訪問的。這裏的username填什麼呢？這個是要和下面的private key配合的，就是指當前訪問git repo遠程倉庫採用的認證屬主，個人demo中，在git遠程倉庫的根目錄下的.ssh裏面那個authorized_keys文件裏面追加的公鑰是root用戶的。在這裏，也是用這個用戶來代理操做clone過程。因此，username是root，private key內容爲/root/.ssh/id_rsa這個私鑰的內容。我選擇的private key的類型是Enter directly，因此，要將私鑰的內容完整的拷貝到這裏喲。注意，-----BEGIN RSA PRIVATE KEY -----以及對應的結尾信息也一併拷貝過來喲。
接下來，須要配置build的策略了，就是build項目的那個分支，我這裏選擇的是master，這個也是系統默認的配置。另外，就是build的觸發機制，我這裏選擇的是週期觸發，這個配置有些相似linux的corn的規則。我這裏配的是但願天天晚上11點半啓動build過程。
點擊schedule右邊的問號按鈕，有詳細的幫助信息。我這裏貼一個簡單的規則描述，方便理解上面配置當中各個數字的含義以及可能都有什麼配置。
This field follows the syntax of cron (with minor differences). Specifically, each line consists of 5 fields separated by TAB or whitespace:
MINUTE HOUR DOM MONTH DOW
MINUTE Minutes within the hour (0–59)
HOUR The hour of the day (0–23)
DOM The day of the month (1–31)
MONTH The month (1–12)
DOW The day of the week (0–7) where 0 and 7 are Sunday.
最後的配置，就是想作什麼的事情。我但願讓其打包，而且不須要執行unit test工做，就是紅色框中的內容。注意，這裏要填寫的是Goals (以及選項，固然選項能夠沒有)，不要帶上mvn指令，不然會出錯的喲。（錯誤信息主體爲：You must specify a valid lifecycle phase or a goal in the format <plugin-prefix>:<goal> or <plugin-group-id>:<plugin-artifact-id> 。。。。）
固然，這當中還有不少其餘的配置，好比build前預處理作什麼，以及build完成後的後處理作什麼，這些均可以經過腳本定義要作的事情。我這裏就什麼也不作。至於郵件通知，公司屏蔽了SMTP端口，沒有辦法發郵件，由於發送的過程當中，會報下面的錯誤：
1 Failed to send out e-mail 2 3 javax.mail.MessagingException: Could not connect to SMTP host: smtp.163.com, port: 25; 4 nested exception is: 5 java.net.NoRouteToHostException: No route to host 6 at

到此，一個基本的job就算配置完畢了，下面看看job配置完成後是什麼樣子呢？
先看看1標記的紅框，S表示status，目前是一個新的job，狀態是灰色的，表示沒有執行過。2標記的信息，看看標題，對應信息能夠看出。3標記的圖標，是一個按鈕，能夠當即啓動job的執行。
那我這裏就當即執行一下吧，看看最後的效果吧。鼠標點擊一下3的按鈕，執行完畢後，上面的圖所示狀態變爲下面的狀態了（S反映的狀態變成藍色的了，若build失敗，會是紅色的。右邊紅色框裏面，能夠看到這個build所用的時間。#1表示第1次build。。。）。相應的日誌也貼出了讓你們參考下吧。
