基於python實現jenkins自動發佈代碼平臺
前言：html
jenkins自動發佈代碼平臺是我2014年6月搭建的，截止目前已經有50多個項目的dev、beta、 生產環境都接入了jenkins，公司開發team中大部分是用GIT管理代碼，也有一部分是用svn管理代碼。個人實現原理是，經過jenkins構建新版本代碼，而後用python腳本發佈到生產環境。用戶在jenkins界面上點擊構建，即完成在線更新發布代碼並郵件通知相關人員發佈成功。java
1、Jenkins安裝部署python
1，部署java環境。(這裏用的是jdk7和tomcat7)linux
mkdir -p /data/webserver cd /data/webserver wget rpm -ivh jdk-7u55-linux-x64.rpm wget tar zxvf apache-tomcat-7.0.53.tar.gz cat > /etc/profile.d/development.sh <<EOF export JAVA_HOME=/usr/java/jdk1.7.0_55 export JRE_HOME=$JAVA_HOME/jre export CLASSPATH=.:$JAVA_HOME/lib:$JRE_HOME/lib:$CLASSPATH export PATH=$JAVA_HOME/bin:$JRE_HOME/bin:$PATH EOF source /etc/profile.d/development.sh
2，部署jenkins項目git
從官網下載jenkins程序包，上傳到服務器的程序目錄，刪除tomcat/webapps目錄下的全部文件，而後修改tomcat配置文件指定程序目錄便可web
<Host name="localhost" appBase="/data/www/jenkins" unpackWARs="true" autoDeploy="true">
啓動tomcat: ./startup.shshell
瀏覽器訪問：http://172.20.0.1:8080/jenkinsapache
2、Jenkins項目構建vim
1，安裝maven插件，因爲部分開發team使用了maven管理，這裏須要安裝maven插件，安裝的是3.2.2版本；瀏覽器
2，私服配置,以下
vim /root/.m2/settings.xml <?xml version="1.0" encoding="UTF-8" standalone="no"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <!--將此文件放在目錄(~/.m2)下作爲maven的設置文件--> <servers> <server> <id>snapshots</id> <username>deployment</username> <password>deployment</password> </server> <server> <id>releases</id> <username>deployment</username> <password>deployment</password> </server> </servers> <mirrors> <mirror> <id>nexus</id> <mirrorOf>*</mirrorOf> <name>internal nexus repository</name> <url>http://172.20.135.19:8080/nexus/content/groups/public/</url> </mirror> </mirrors> <profiles> <profile> <id>nexus</id> <repositories> <repository> <id>central</id> <url>http://nisabi</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </repository> </repositories> <pluginRepositories> <pluginRepository> <id>central</id> <url>http://nisabi</url> <releases> <enabled>true</enabled> </releases> <snapshots> <enabled>true</enabled> </snapshots> </pluginRepository> </pluginRepositories> </profile> </profiles> <activeProfiles> <activeProfile>nexus</activeProfile> </activeProfiles> </settings>
3，在jenkins操做界面---系統管理---插件管理中，安裝git、go插件，svn已經默認安裝，因爲開發項目有用到go語言，這裏須要安裝go插件；
4，在jenkins操做界面新建一個項目，能夠選擇自由風格軟件項目或maven項目，在配置中填寫源碼管理地址、受權賬號、Branches to build（分支名）、pom.xml（根據具體項目來寫）、add-post-build-step-----execute shell;
5，在execute shell框中填寫服務器腳本地址，保存便可
3、Python發佈腳本

此腳本的功能說明以下：
1，將構建好的代碼包，用rsync同步到生產環境服務器中轉目錄program；
2，經過ssh登陸生產環境服務器，調用program_update.sh腳本，將中轉目錄program下的代碼更新到站點程序目錄，更新完以後若是站點訪問有BUG，那麼能夠將program下的前一個版本代碼進行回滾；
3，構建的代碼包和上傳到生產環境的代碼包經過md5校驗一致性；
4，項目構建發佈成功後，發郵件給項目相關人員；
5，執行此腳本的日誌輸出到文件，能夠進行查看問題；
關於jenkins平臺的項目構建操做很簡單，但願個人文章能夠給你們有所幫助，若有問題能夠諮詢我，也但願你們給予建議！
