Jenkins学习笔记3

git+github+jenkins：

架构图：

说明：jenkins知道github有更新了，就pull进行构建build，编译、自动化测试。然后部署到应用服务器。

maven java的项目构建工具。

在开发者电脑上创建空密码密钥对。

bash 复制代码

[root@git-developer ~]# git clone git@github.com:changchunhua2017/jenkins.git
Cloning into 'jenkins'...

bash 复制代码

[root@git-developer jenkins]# git config --global user.name "changchunhua"
[root@git-developer jenkins]# git config --global user.email "chang_chunhua@qq.com"
[root@git-developer jenkins]# git config --global color.ui true

[root@git-developer jenkins]# echo 11111 > 1.php
[root@git-developer jenkins]# ll
total 8
-rw-r--r-- 1 root root  6 Sep 20 15:50 1.php
-rw-r--r-- 1 root root 35 Sep 20 15:27 README.md

[root@git-developer jenkins]# git add *
[root@git-developer jenkins]# git commit -m "Added 1.php"
[main cdc0119] Added 1.php
 1 file changed, 1 insertion(+)
 create mode 100644 1.php

可以看到1.php文件上传成功：

那开发者这块是没有问题的。

Nginx服务器的准备：

在Nginx服务器上安装nginx，并启动nginx。

bash 复制代码

[root@nginx ~]# yum install epel-release
[root@nginx ~]# yum install nginx -y
[root@nginx ~]# systemctl start nginx
[root@nginx ~]# systemctl enable nginx

jenkins安装插件：

jenkins图形安装publish over ssh插件：

可以看到Publish Over SSH插件已经安装完成。

确认Git plugin插件已经安装完成。

配置Jenkins服务器通过Publish over ssh免密连接Nginx：

1）第1步: 在jenkins服务器上生成空密码密钥对：

bash 复制代码

[root@localhost soft]# ssh-keygen

2）查看并复制私钥：

bash 复制代码

[root@localhost .ssh]# cat id_rsa
-----BEGIN RSA PRIVATE KEY-----

-----END RSA PRIVATE KEY-----

这段私钥，只是代表这台服务器的root账户私人免密，并不能代表jenkins软件免密。

3）在Jenkins中添加私钥：

安装了插件，才有这个Publish over SSH。

还需要添加要连的服务器：

然后点击保存。

还可以做一个测试。

这样，就是配置jenkins软件的私钥。

私钥是解密，公钥是加密。

4）在jenkins服务器上配置对nginx服务器的免密登录。

bash 复制代码

[root@localhost .ssh]# ssh-copy-id -i 192.168.17.121
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
The authenticity of host '192.168.17.121 (192.168.17.121)' can't be established.
ECDSA key fingerprint is SHA256:4dogA08L5gdfaA69BGekE13kzSuIP2vcRp9rsqYnpn0.

/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed

root@192.168.17.121's password:

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh '192.168.17.121'"
and check to make sure that only the key(s) you wanted were added.

把Jenkins的服务器的公钥给Github：

直接将id_rsa.pub内容配置到Github中。
