Install 安装

$ yarn global add @ddn/capistrano

Use 使用

部署分为两个步骤：

1. 安装本地

$ deploy init

在本地工程目录，生成如下配置文件（建议将下面的deploy文件夹，特别是其中的pem文件夹及其文件，放在.gitignore里）

project
    |___ config 没有就建立；
        |___deploy 没有就建立
                |____ config.js 配置文件
                |____ pem 服务器登录私钥

2. 部署任务

$ deploy prod

该命令将初始化服务端环境：

project
    |___current 当前工作目录，通过软连接指向 versions最新版本目录；
    |___versions 各个旧的版本工作目录，方便回滚
    |___shared 数据持久化目录，方便备份和数据安全
            |____ config.* 各种配置文件，可能包含敏感信息
            |____ tmp 缓存文件
            |____ logs 日志文件
            |____ database 数据库文件

执行结果如下：

$ deploy prod

FAQ

首先保证本地可以登录远程服务器；

$ ssh -i path-to-pem root@your-id

确保远程可以正常 fork 代码

$ git clone repo_url

如果无法克隆，按照下列步骤操作

$ ssh -T git@github.com
# git@github.com: Permission denied (publickey).

产生 ssh-key

$ ssh-keygen -t rsa -b 4096 -C 'your@email.com'
$ cat ~/.ssh/id_rsa.pub

将产生的公钥拷贝到版本库 -> deploy key 里

bash: yarn: command not found 错误

该错误是使用 nvm 安装的原因，只要下面两步

$ npm config set prefix /usr/local
$ npm i -g yarn

/usr/bin/env: ‘node’: No such file or directory

这也是 nvm 安装，导致没有命令行交互时出现的错误

$ which node
$ ln -s /root/.nvm/versions/node/v10.19.0/bin/node /usr/bin
