github+maven+jenkins(spring boot项目自动化发布)

一.安装jenkins

1.下载jenkins稳定版本的war包（https://www.jenkins.io/download/）。

2.服务器安装jenkins

[root@rancher1 jenkins]# useradd jenkins
[root@rancher1 jenkins]# cd /home/jenkins/
[root@rancher1 jenkins]# ls -lart
total 12
-rw-r--r--  1 jenkins jenkins 231 Apr 11  2018 .bashrc
-rw-r--r--  1 jenkins jenkins 193 Apr 11  2018 .bash_profile
-rw-r--r--  1 jenkins jenkins  18 Apr 11  2018 .bash_logout
drwxr-xr-x  4 jenkins jenkins  39 Mar 20  2020 .mozilla
drwxr-xr-x. 6 root    root     58 Oct 29 23:39 ..
drwx------  3 jenkins jenkins  78 Oct 29 23:39 .
[root@rancher1 jenkins]#

上传jdk安装包(https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html)及jenkins安装包

[jenkins@rancher1 ~]$ ls -lrt
total 251132
-rw-r--r-- 1 root root  67399569 Oct 29 23:41 jenkins.war
-rw-r--r-- 1 root root 189756259 Oct 29 23:41 jdk-8u161-linux-x64.tar.gz

配置java环境变量

[jenkins@rancher1 ~]$tar zxvf  jdk-8u161-linux-x64.tar.gz
修改.bash_profile
[jenkins@rancher1 ~]$ cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
export JAVA_HOME=/home/jenkins/jdk1.8.0_161
export PATH=$JAVA_HOME/bin:$PATH
加载环境变量
[jenkins@rancher1 ~]$ source .bash_profile

[jenkins@rancher1 ~]$ java -version
java version "1.8.0_161"
Java(TM) SE Runtime Environment (build 1.8.0_161-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.161-b12, mixed mode)

启动jenkins，war默认起8080端口

[jenkins@rancher1 ~]$ nohup java -jar jenkins.war &
[1] 5548
[jenkins@rancher1 ~]$ nohup: ignoring input and appending output to ‘nohup.out’

google访问jenkins（http://192.168.56.140:8080/）

copy管理员密码

[jenkins@rancher1 ~]$ cat /home/jenkins/.jenkins/secrets/initialAdminPassword
7a838bec2fd84cddb2ce1e7a639b66fe

建议选择安装推荐插件

安装必要的插件

创建管理员用户

修改插件更新地址（国内地址）：系统管理-》插件管理-》高级

安装git

下载git（https://github.com/git/git）

[jenkins@rancher1 ~]$ ls -lh
total 76M
-rw-r--r-- 1 jenkins jenkins  11M Oct 29 17:18 git-master.zip
drwxr-xr-x 8 jenkins jenkins  255 Dec 20  2017 jdk1.8.0_161
-rw-r--r-- 1 root    root     65M Oct 29 23:41 jenkins.war
-rw------- 1 jenkins jenkins 116K Oct 30 15:42 nohup.out
drwxr-xr-x 8 jenkins jenkins   90 Oct 30 01:42 share
[jenkins@rancher1 ~]$ unzip git-master.zip

[jenkins@rancher1 ~]$ cd git-master

[jenkins@rancher1 git-master]$ make
[jenkins@rancher1 git-master]$ make install

查看git版本

[jenkins@rancher1 ~]$ git --version
git version 2.29.GIT

安装maven

maven下载（http://maven.apache.org/download.cgi）

解压，设置环境变量即可

tar zxvf apache-maven-3.6.3-bin.tar.gz

#环境变量配置
[jenkins@rancher1 ~]$ cat .bash_profile 
# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
	. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/.local/bin:$HOME/bin

export PATH
export JAVA_HOME=/home/jenkins/jdk1.8.0_161
export MAVEN_HOME=/home/jenkins/apache-maven-3.6.3
export PATH=$JAVA_HOME/bin:$MAVEN_HOME/bin:$PATH
[jenkins@rancher1 ~]$ source .bash_profile 
查看maven版本
[jenkins@rancher1 ~]$ mvn --version
Apache Maven 3.6.3 (cecedd343002696d0abb50b32b541b8a6ba2883f)
Maven home: /home/jenkins/apache-maven-3.6.3
Java version: 1.8.0_161, vendor: Oracle Corporation, runtime: /home/jenkins/jdk1.8.0_161/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "5.5.10-1.el7.elrepo.x86_64", arch: "amd64", family: "unix"

修改maven镜像地址为国内镜像

cd /home/jenkins/apache-maven-3.6.3/conf
修改settings.xml文件
<mirrors></mirrors>中间增加

    <mirror>
     <id>nexus-aliyun</id>
     <mirrorOf>central</mirrorOf>
     <name>Nexus aliyun</name>
     <url>http://maven.aliyun.com/nexus/content/groups/public</url>
    </mirror>

jenkins安装Publish Over SSH插件，支持远程发布功能（插件安装完成后，重启才能生效）

安装maven插件

jenkins配置jdk，git，maven等信息

系统管理-》全局工具配置

配置ssh信息（远程发布的机器信息）

系统管理-》系统配置

配置完成后，点击test configuration测试。

新建任务

该任务的绝对地址是：/home/jenkins/.jenkins/workspace/ywgk/

source file等于自动在前面加了/home/jenkins/.jenkins/workspace/ywgk/

立即构建，查看日志。

构建报错，因为oracle驱动是oracle原厂的，镜像仓库不能下载。

[jenkins@rancher1 ojdbc14]$ pwd
/home/jenkins/.m2/repository/com/oracle/ojdbc14

手工上传oracle驱动，再次构建。

访问平台

远程机器start.sh脚本

[app@exam ~]$ cat start.sh 
#!/bin/bash
ps -ef|grep java|grep ywgk|awk '{print $2}'|xargs kill 
java -jar ywgk-0.0.1-SNAPSHOT.jar > ywgk.log &
