用浏览器访问192.168.10.253:8080
密码就是上面一串
jenkins

点推荐，这个过程取决于你的网速
jenkins

显示插件数
[root@jenkins ~]# ls /var/lib/jenkins/plugins/|wc -l
146

用户名为jenkins
jenkins

jenkins

1、安装插件gitlab+blue ocean
jenkins

jenkins

安装过程
jenkins

systemctl restart jenkins

创建一个任务
jenkins

jenkins

jeknins

安装role-based 使用这个插件做授权管理
jenkins

jenkins

设置完成后不要退出不要退出不要退出
jenkins

创建一个用户
jenkins

jenkins

看到所创建的用户没有任务权限
jenkins

设置权限在系统管理
jenkins

jenkins

只给read一个权限
jenkins

jenkins

最好在开一个浏览器做下测试，使用刚创建的用户登陆下

关联任务
jenkins

配置邮件
jenkins

jenkins

获取邮箱的授权码
jenkins

jenkins

用USER1用户登陆构建一个
jenkins

jenkins

jenkins生成sshkey

[root@jenkins ~]# ssh-keygen
[root@jenkins ~]# cat /root/.ssh/id_rsa.pub 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDepqIhyHOxr14B+vD4DwRN00fYxJ6ylbs4eiT/Cm+GFEh+A54ZNwPq48/lNQFD3Ue/7AAqxLztxqFiu+epuOcMwRYp8ZccY7M6XeMJHU+J8RKn0PnyvGiVjmIQrR/81OO6EYlmDd2qiBEhYa8j8n88aGu9jb0Fd9E6BbWgw6jVUNsUc4uTH9IfnZMhRAK7p2OneXqMEz9NGa157h/2JQZXIpYxTPWsXDVbaxWIyvjI5//6xBQzC9wgd2URKDNFPck5ZRcFs3uCSx6zir36kxpltqCAFet04MG72lZlsHrw8m+4YBZBjCIeXw+G8/Z+/QZP7ZACgGy16CtldGbV+yyD root@jenkins

用浏览器访问gitlab服务器
jenkins

上传jenkins服务器的公钥
jenkins

jenkins

测试git结果
git clone git@192.168.10.254:web233/web1.git

获取私钥
cat /root/.ssh/id_rsa
在jenkins添加私钥
jenkins

jenkins

构建开始前删除工作区(开始前删除目录)
jenkins

jenkins

ll -i /var/lib/jenkins/workspace

jenkins与tomcat1 2做免密钥登陆
ssh-copy-id -p22 www@192.168.10.230
ssh-copy-id -p 22 www@192.168.10.231

代码如下

whoami
#打包过程
cd /var/lib/jenkins/workspace/test && zip -r web233.zip ./*

#停止tomcat服务
ssh -p22 www@192.168.10.230 "/etc/init.d/tomcat stop"
ssh -p22 www@192.168.10.231 "/etc/init.d/tomcat stop"

#传送文件到web服务器
scp -P22 web233.zip www@192.168.10.230:/data/tomcat/webapps/testapp
scp -P22 web233.zip www@192.168.10.231:/data/tomcat/webapps/testapp

#代码替换
ssh -p22 www@192.168.10.230 "cd /data/tomcat/webapps/testapp/ && rm -rf ./index.* && unzip web233.zip && rm -rf web233.zip"
ssh -p22 www@192.168.10.231 "cd /data/tomcat/webapps/testapp/ && rm -rf ./index.* && unzip web233.zip && rm -rf web233.zip"

#启动tomcat服务
ssh -p22 www@192.168.10.230 "/etc/init.d/tomcat start"
ssh -p22 www@192.168.10.231 "/etc/init.d/tomcat start"

jenkins

暂时没有找到解决方法，所以
一定要把jenkins用户改为root
一定要把jenkins用户改为root
一定要把jenkins用户改为root
[root@jenkins ]# grep root /etc/sysconfig/jenkins
JENKINS_USER="root"

可以在控制台输出可以看到
jenkins

测试上传一个GIT版本，然后构建

git clone http://192.168.10.254/web233/web1.git
lscd web1/
cat index.html 
this is web233 test v1...
this is web233 test v2...
this is web233 test v3...
vim index.html 
this is web233 test v1...
this is web233 test v2...
this is web233 test v3...
this is web233 test v4...
git add ./* 
git commit -m "v4"
git push

jenkins

http://192.168.10.230:8080/testapp/
http://192.168.10.231:8080/testapp/
http://192.168.10.233/testapp/

jenkins添加节点

jenkins

[root@jenkins1 ~]# mkdir -pv /var/lib/jenkins/workspace

注意jenkins-slave java环境放在/usr/local/java

jenkins

名字、描述和标签尽量保持一致

jenkins

可以通过日志查看部署jenkins slave进度
jenkins

jenkins

在建立一个新的节点jenkins-slave2

[root@jenkins2 ~]# mkdir -pv /var/lib/jenkins/workspace

jenkins

查看日志
jenkins
有这些提示，说明JDK没安装，或者环境变量未设置好

jenkins

安装JDK完成后就好了,java环境尽量放在/usr/local/java

jenkins
