Linux Centos7安装Jenkins使用Git自动化部署项目

一步步教你部署项目到Jenkins上

环境Centos7.8

1.安装jdk1.8

jenkins只支持jdk1.8
下载：jdk-8u281-linux-x64.tar.gz
解压：tar -xzvf jdk...  
拷贝到/usr/lcoal/jdk8

新建环境变量
vim /etc/profile.d/jdk.sh
	export JAVA_HOME=/usr/local/jdk8
	export PATH=$JAVA_HOME/bin:$PATH
	
环境变量生效
chmod a+x /etc/profile.d/jdk.sh
source /etc/profile.d/jdk.sh
java -version

2.安装maven

下载：apache-maven-3.6.3-bin.tar.gz
解压：tar -zxvf apache-maven...   拷贝到/usr/lcoal/maven

新建环境变量
vim /etc/profile.d/maven.sh
	export MAVEN_HOME=/usr/local/maven
	export PATH=$MAVEN_HOME/bin:$PATH 
	
环境变量生效
chmod a+x /etc/profile.d/maven.sh
source /etc/profile.d/maven.sh
mvn -v

设置阿里云maven镜像：
在/usr/local/maven/conf目录中找到settings.xml 文件，在mirrors的子节点添加如下
<mirror>
    <id>nexus-aliyun</id>  
    <mirrorOf>central</mirrorOf>    
    <name>Nexus aliyun</name>  
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>  
</mirror>

3.源码编译安装git

下载：wget https://www.kernel.org/pub/software/scm/git/git-2.9.5.tar.gz
解压：tar -zxvf git-2.9.5

设置安装目录
	cd git-2.9.5
	./configure --prefix=/usr/local/git/
开始编译安装
	make && make install

创建软连接
ln -sf /usr/local/git/bin/git /bin/
ln -sf /usr/local/git/bin/git-upload-pack /bin/
ln -sf /usr/local/git/bin/git-cvsserver /bin/
ln -sf /usr/local/git/bin/gitk /bin/
ln -sf /usr/local/git/bin/git-receive-pack /bin/
ln -sf /usr/local/git/bin/git-shell /bin/
ln -sf /usr/local/git/bin/git-upload-archive /bin/
git --version

4.安装Jenkins

设置源
vim /etc/yum.repos.d/jenkins.repo
内容：
------------------------------------------------------
[jenkins]
name=Jenkins-stable
baseurl=http://pkg.jenkins.io/redhat-stable
gpgcheck=1
------------------------------------------------------
翻墙下载这个文件上传到linux
https://pkg.jenkins.io/redhat-stable/jenkins.io.key
导入这个key文件
rpm --import ~/jenkins-ci.org.key
安装
yum -y install jenkins

5.编辑文件，添加jdk1.8的目录

vim /etc/init.d/jenkins

6.启动：systemctl daemon-reload && systemctl start jenkins

7.修改端口：vim /etc/sysconfig/jenkins

JENKINS_PROT="8086"
JENKINS_USER="root"

8.防火墙放行端口访问：http://xxx:8086

9.查看登录密码：cat /var/lib/jenkins/secrets/initialAdminPassword
