jenkins的安装

一、安装git

1.安装依赖
    yum install curl-devel expat-devel gettext-devel openssl-devel zlib-devel gcc perl-ExtUtils-MakeMaker -y
 
2.下载安装包https://github.com/git/git/releases
    wget https://github.com/git/git/archive/v2.21.0.tar.gz
 
3. 源码安装git
    tar -zxvf v2.21.0.tar.gz #解压
    cd git-2.21.0
    make prefix=/usr/local/git all #编辑
    make prefix=/usr/local/git install #安装
 
4. 编辑环境配置文件
    vim /etc/profile
    # 末尾添加
    export PATH=$PATH:/usr/local/git/bin
    # 生效环境变量
    source /etc/profile<br>5.检验安装<br>　　git --version

二、安装jdk

1. 解压安装
    tar -zxvf jdk-8u151-linux-x64.tar.gz -C /usr/local/
    cd /usr/local/
    mv jdk1.8.0_151 jdk
2.添加环境变量
    vim /etc/bashrc
    #添加以下代码   
    JAVA_HOME=/usr/local/jdk
    CLASSPATH=$JAVA_HOME/lib/
    export PATH=$PATH:$JAVA_HOME/bin
    #重新加载环境变量
    source /etc/bashrc
3.检验安装
　　java -version

三、安装maven

1.下载安装包 http://mirror.bit.edu.cn/
    wget http://mirror.bit.edu.cn/apache/maven/maven-3/3.5.4/binaries/apache-maven-3.5.4-bin.tar.gz
2.解压安装
    tar -xzvf apache-maven-3.5.4-bin.tar.gz -C  /usr/local/
    mv /usr/local/apache-maven-3.5.4-bin.tar.gz  /usr/local/maven
3.添加环境变量
    vim /etc/bashrc
    export M2_HOME=/usr/local/maven
    export M2=$M2_HOME/bin
    PATH=$M2:$PATH
    source /etc/bashrc
4.检验安装
    mvn -version

四、安装tomcat

1.解压安装
    tar xvzf apache-tomcat-9.0.1.tar.gz -C /usr/local/
    mv /usr/local/apache-tomcat-9.0.1 /usr/local/tomcat
2.添加环境变量
    vim /etc/profile
    CATALINA_HOME=/usr/local/tomcat
    export CATALINA_HOME
    source /etc/profile
3.启动与关闭
    /usr/local/tomcat/bin/startup.sh#启动
    /usr/local/tomcat/bin/shutdown.sh#关闭

五、安装jenkins

jenkins网址：http://mirror.bit.edu.cn/jenkins/war/
 
1.下载jenkins
    wget http://mirror.bit.edu.cn/jenkins/war/2.167/jenkins.war
 
2.将jenkins.war放到tomcat中,启动tomcat时自动解压webapps下的war包
    cp jenkins.war /usr/local/tomcat/webapps/
 
3. 网址访问jenkins,查看密码
    cat /root/.jenkins/secrets/initialAdminPassword
 
4.管理插件.选择推荐安装，自动安装插件，安装插件失败后，进入主页再手动安装.以下插件为必须
    GIT plugin
    Publish Over SSH
    Maven Integration plugin
    Deploy to container
    Maven Integration
    GitHub Authenticattion plugin
    GitHub Branch Sourch Plugin
    GitHub Organization Folder Plugin

    jdk:
    去掉自动安装，JDK=jdk1.8.0,JAVA_HOME=/usr/local/jdk
    git:
    去掉自动安装，Name:Default;Path to Git executable:/usr/local/git/bin/git
    maven:
    去掉自动安装,name:maven3.5.3;MAVEN_HOME:/usr/local/maven
 
6.系统配置.ssh设置，手动配置ssh key，通过ssh自动化推送到远程服务器
    a).jenkins服务器准备秘钥认证
    ssh-keygen #生成秘钥对,位于/root/.ssh/
    ssh-copy-id -i 139.155.39.45 #设置远程服务器免钥登录
    ssh root@139.155.39.45 #免钥登录
 
    b).jenkins系统配置中设置ssh
        Path to key=/root/.ssh/id_rsa
    c).jenkins系统配置中添加ssh server远程服务器
