Jenkins + Pipeline + Git + Maven （十）

一、准备环境介绍

192.168.5.71     # gitlab 仓库IP
192.168.5.72     # 开发环境，用于提交代码等
192.168.5.73     # tomcat 部署solo服务站点
192.168.5.239    # jenkins 服务器

二、在WEB机器（73）上面部署tomcat + maven环境

2.1 安装JDK，jenkins中添加slave节点需要

# tar xf jdk-8u111-linux-x64.tar.gz -C /usr/local/
# ln -s /usr/local/jdk1..0_111 /usr/local/jdk
# vim /etc/profile
export JAVA_HOME=/usr/local/jdk
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin

2.2 安装maven环境，打war包的时候需要

# wget https://archive.apache.org/dist/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz
# tar xf apache-maven-3.5.-bin.tar.gz -C /usr/local/
# ln -s /usr/local/apache-maven-3.5./ /usr/local/maven

2.3 安装tomcat环境

# tar xf apache-tomcat-8.5..tar.gz -C /usr/local/
# ln -s /usr/local/apache-tomcat-8.5. /usr/local/tomcat
# cd /usr/local/tomcat/webapps/
# rm -rf *

2.4 创建备份目录

# mkdir -p /data/backup

2.5 对git服务器进行免密认证

# ssh-keygen -t rsa -P '' -f ~/.ssh/id_dsa
# ssh-copy-id -i /root/.ssh/id_dsa.pub git@192.168.5.71

2.6 安装unzip解压war包命令，也可以不安装，1.8会热解压，安装mariadb数据库，将数据库密码设置为123456，并创建solo数据库

# yum install unzip mariadb-server mariadb -y
# mysqladmin -uroot password ''
# mysql -uroot -p123456
MariaDB [(none)]> create database solo;

数据库密码也可以修改solo v3.6.6源码包，具体目录如下

# vim solo/src/main/resources/local.properties
#### MySQL runtime ####
runtimeDatabase=MYSQL
jdbc.username=root
jdbc.password=
jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.URL=jdbc:mysql://localhost:3306/solo?useUnicode=yes&characterEncoding=UTF-8&useSSL=false&serverTimezone=UTC

三、在git服务器（71）上面创建solo仓库

# su - git
$ mkdir repo/solo
$ cd repo/solo/
$ git --bare init
Initialized empty Git repository in /home/git/repo/solo/

git仓库已创建好，仓库地址是：git@192.168.5.71:/home/git/repo/solo

四、在开发机下载solo 3.6.6版本并上传到git仓库

# git clone git@192.168.5.71:/home/git/repo/solo
# wget https://codeload.github.com/b3log/solo/tar.gz/v3.6.6
# tar xf v3.6.6
# mv solo-3.6./* solo/
# cd solo/

# 修改solo配置文件
# grep server src/main/resources/latke.properties
serverScheme=http
serverHost=solo.leon.com
serverPort=8080

# 上传代码
# git add .
# git commit -m 'all solo file'
# git push origin master

五、开发机编写jenkinsfile文件

# git clone git@192.168.5.71:/home/git/repo/jenkinsfile
# cd jenkinsfile/
# mkdir java-solo
# cd java-solo/

jenkinsfile文件如下：

tomcat发布项目要重启服务

node ("192.168.5.73") {
   //def mvnHome = '/usr/local/maven'
   stage('git checkout') {
        checkout([$class: 'GitSCM', branches: [[name: '*/master']], doGenerateSubmoduleConfigurations: false, extensions: [], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'ccf5f140-9a28-49d6-abc8-40bc6c750323', url: 'git@192.168.5.71:/home/git/repo/solo']]])
   }
   stage('maven build') {
        sh '''export JAVA_HOME=/usr/local/jdk
        /usr/local/maven/bin/mvn clean package -Dmaven.test.skip=true'''
   }
   stage('deploy') {
        sh '''
        JENKINS_NODE_COOKIE=dontkillme
        export JAVA_HOME=/usr/local/jdk
        TOMCAT_NAME=tomcat
        TOMCAT_HOME=/usr/local/$TOMCAT_NAME
        WWWROOT=$TOMCAT_HOME/webapps/ROOT

        if [ -d $WWWROOT ]; then
           mv $WWWROOT /data/backup/${TOMCAT_NAME}-$(date +"%F_%T")
        fi
        unzip ${WORKSPACE}/target/*.war -d $WWWROOT
        PID=$(ps -ef |grep $TOMCAT_NAME |egrep -v "grep|$$" |awk \'{print $2}\')
        [ -n "$PID" ] && kill -9 $PID
        /bin/bash $TOMCAT_HOME/bin/startup.sh'''
   }
}

# cat jenkinsfile/java-solo/jenkinsfile

push代码：

# cd jenkinsfile/
# git add .
# git commit -m 'add java-solo jenkinsfile'
# git push origin master

六、配置Jenkins

6.1 添加slave机器

从节点配置信息

 6.2 创建一个solo-java的pipeline配置如下

 6.3 进行构建

七、如果遇到的坑

7.1 jenkins启动服务器自动关闭

原因：pipeline启动的tomcat进程是jenkins派生的，当job完成之后jenkins会自动关闭自己派生的进程。所以tomcat会被关闭。在jenkinsfile中加入此行内容。

JENKINS_NODE_COOKIE=dontkillme

7.2 solo没有皮肤的导致tomcat启动失败

[ERROR]-[-- ::]-[org.b3log.latke.Latkes:]: Read skin [Pinghsu]'s configuration failed: null
[ERROR]-[-- ::]-[org.b3log.solo.SoloServletListener:]: Can't load the default skins, please make sure skin [Pinghsu] is under skins directory and structure correctly

经查看此目录是空的

# ls solo-3.6./src/main/webapp/skins/

解决方法：下载新的solo源码包，将其skins目录的文件拷贝到上面的目录即可

# cp -r solo/src/main/resources/skins/ solo-3.6.6/src/main/webapp/skins/
