Jenkins+GitLib持续集成[贰]安装Jenkins：https://www.iyunw.cn/archives/jenkins-gitlib-chi-xu-ji-cheng-er-zhuang-jenkins/

一、通过gitlab构建第一个任务，获取gitlab的代码。

    1.首先，我们需要jenkins能够获取gitlab代码，我们需要在运行jenkins的用户下ssh-keygen生成密钥，然后在gitlab上添加公钥。

[jenkins@lb2 ~]$ ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/home/jenkins/.ssh/id_rsa): 
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /home/jenkins/.ssh/id_rsa.
Your public key has been saved in /home/jenkins/.ssh/id_rsa.pub.
The key fingerprint is:
bc:33:63:1c:77:d9:66:bf:18:30:eb:64:ab:15:0e:70 jenkins@lb2.iyunw.cn
The key's randomart image is:
+--[ RSA 2048]----+
|                 |
|                 |
|       . E       |
|       .o    o   |
|        S..+o +  |
|       . +o.=o . |
|        B  * .  .|
|       . += . o .|
|         ..o . . |
+-----------------+

     2.去gitlab上添加刚生成的公钥

    在jenkins用户下git测试是否可以通过git工具直接git数据来测试密钥是否正常，有关git命令可以参考廖雪峰的git教程，非常详细

[jenkins@lb2 web]$ git config --global user.name "admin"
[jenkins@lb2 web]$ git config --global user.email 351937287@qq.com
[jenkins@lb2 ~]$ git clone git@lb1:app1/web.git

[jenkins@lb2 web]$ git commit -m 'add 123'

[jenkins@lb2 web]$ git push

     4.然后登录jenkins创建任务

到此  ，可以看到同步成功

二、同步完成我们需要吧代码同步发布到web（rsync）

   1、同样，我们需要jenkins用户免密钥登录web1，因为我们需要rsync同步免密钥

[jenkins@lb2 ~]$ ssh-copy-id -i ~/.ssh/id_rsa.pub tommy@web1
The authenticity of host 'web1 (192.168.80.210)' can't be established.
RSA key fingerprint is c1:9e:41:da:17:eb:d2:f0:72:1b:a6:97:49:58:3d:50.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added 'web1,192.168.80.210' (RSA) to the list of known hosts.
tommy@web1's password: 
Now try logging into the machine, with "ssh 'tommy@web1'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

     我们更新任务，添加构建步骤，执行shell

我们从新执行任务，就可以看到数据无差异同步到了web1  data目录

到此   jenkins+gitlab通过rsync无差异发布就完成
