1. jenkins-nodejs-publish¶

使用Jenkins自动部署nodejs应用

1.1. env1¶

120.25.204.216 jenkins master
10.10.15.181 jenkins remote-server

1.2. env2¶

10.10.15.181 jenkins master
10.10.15.181 jenkins remote-server

1.3. reference¶

http://blog.csdn.net/frank_good/article/details/68930286

1.4. 安装插件¶

系统管理 -> 插件管理

主要是安装 Publish Over SSH, SSH plugin

GIT client
GIT
Git server
GitHub API
GitHub
SSH Credentials
SSH
Publish Over SSH

安装完成后，重新启动 jenkins。如果无法自动重启，可以输入 ‘/restart’ 在地址栏，即可手动重启。

1.5. 添加remote计算机¶

系统管理 -> 系统设置

SSH remote hosts¶

增加remote server 这个是增加ssh remote 插件的服务器

点击新增

Hostname 写入 api-ct.zhangtl.com: Port 写入 6000 Credentials 点击 Add , 选择 jenkins (这里其实是之前配置的一个credential)

点击 Check connection, 如显示 Successfull connection, 表示连接成功

增加远程拷贝文件的remote server

Publish over SSH¶

Jenkins SSH Key: Passphrase 选择密码, •••••••••••••••••••••••••••••••••••••••••••••••••••••••••• Path to key 写入 /var/lib/jenkins/.ssh/id_rsa 这个就是 master 的私钥 Key 这里可以不填写. 如果说上面没有写私钥的地址,那这里就直接把私钥复制到这里.也就是2者写1就行了 Disable exec 不动, 不打勾 SSH Servers
SSH Server 这个就是远程的server 的信息了: Name 写入 api-ct.zhanglt.com.6000.jenkins, 这个是给自己看的 Hostname 写入 api-ct.zhangtl.com 这个是要解析的,也就是IP了 Username 写入 jenkins 用户名 Remote Directory 写入 /var/lib/jenkins 这里我写的是 jenkins 用户的 $HOME 目录,

点击 Test Configuration, 如显示 Success 表示成功了.

1.6. 创建项目¶

我现在在github上建了一个nodejs的helloworld项目： https://github.com/tomtsang/jenkinsNodejs 是 fork 于 https://github.com/DoubleSpout/jenkinsNodejs

我们需要在jenkins中也创建一个相应的项目来，依次点击：新建 -> 取名为 nodejsPublish

进入项目，点击配置，我们就可以对这个项目进行配置，让它自动部署

General¶

Github project

Project url 写入 https://github.com/tomtsang/jenkinsNodejs/

源码管理¶

设置 git 仓库路径

Git / Repositories: Repository URL 写入 https://github.com/tomtsang/jenkinsNodejs/ Credentials 可以不选择, 选择也可以, 我是 Add, 选择 jenkins 这个.

因为是公共仓库，所以可以不需要验证用户名，密码

构建¶

Execute shell¶

构建完毕之后，将代码打包保存, 所以增加一个构建完毕的shell脚本执行

具体的是, 打包代码，然后移动到workspace目录下

点击增加构建步骤, 选择 Execute shell, command 写入

#rm -rf /var/lib/jenkins/jobs/nodejsPublish/nodejsPublish.tar.gz
#tar -zcvf /tmp/nodejsPublish.tar.gz -C /var/lib/jenkins/jobs/nodejsPublish/workspace/ .
tar -zcvf /tmp/nodejsPublish.tar.gz -C /var/lib/jenkins/workspace/nodejsPublish/ .
mv /tmp/nodejsPublish.tar.gz /var/lib/jenkins/workspace/nodejsPublish/
echo {$HOME}
echo "Execute shell"

Execute shell script on remote host using ssh¶

接着我们需要连接到部署服务器上，将原来的服务暂时暂停，删除上一次部署的压缩包，选择添加远程shell脚本执行，如:将pm2服务停止，这里大家可以根据自己的要求写脚本

点击增加构建步骤, 选择 Execute shell script on remote host using ssh,

SSH site 选择 jenkins@api-ct.zhangtl.com:6000 , 这个选择项目也就是上面配置的Publish over SSH/SSH Server的结果

command 写入

pm2 stop all
pm2 delete all
echo {$HOME}
echo  "Execute shell script on remote host using ssh"

Send files or execute commands over ssh¶

最后我们要把打包好的代码发送到服务器上，然后执行安装依赖包操作，并且启动nodejs服务，

也就是选择通过ssh发送文件并执行命令到远程服务器, 然后解压代码，执行依赖包安装，然后通过pm2启动nodejs服务。

点击增加构建步骤, 选择 Send files or execute commands over ssh,

SSH Publishers / SSH Server

Name: 选择 api-ct.zhanglt.com.6000.jenkins
Transfers / Transfer Set: Source files 写入 nodejsPublish.tar.gz, Source files的默认当前路径就是workspaces，也就是 /var/lib/jenkins/workspace/, 这里写入的是它的相对路径 Remove prefix 不写 Remote directory 写入 tom/nodejsPublish/ , Remote directory的当前路径就是之前添加远程服务器设置的，我当时设置为/var/lib/jenkins/, 同样写相对路径 Exec command 写入如下:

echo {$HOME}
ls -l
ls tom/nodejsPublish/

这个 Exec command 下方会有红色提示(但是我发现没有关系, 不受影响, 这是为什么? 求赐教), 提示如下:

Either Source files, Exec command or both must be supplied

1.7. 开始构建¶

配置好上述命令之后，我们点击保存，然后点击立即构建，

出现蓝色的球，就表示构建成功，红色的球表示构建失败，黄色的球表示执行构建命令失败，

不论构建成功还是失败，我们可以通过查看控制台输出看到构建的结果

如果我们有多台设备，就只需要配置一次，然后以后每次有代码变更，手动点击立即构建即可自动部署到目标服务器，免去我们枯草的重复劳动。

当然其他语言，例如python，php都是可以这样来部署的。

1.8. jenkins log¶

我本次的控制台输出如下
