本地沙箱创建详情

完成沙箱环境初始化剧本所执行的具体步骤与输出结果

在本地拉起沙箱时所执行的Makefile快捷命令，以及其输出结果。

拉起本地沙箱

1. # 下载本项目代码
2. cd /tmp && git clone git@github.com:Vonng/pigsty.git && cd pigsty

4. make up         # 拉起vagrant虚拟机
5. make ssh        # 配置虚拟机ssh访问      【单次，下次启动无需再次执行】
6. sudo make dns   # 写入Pigsty静态DNS域名  【sudo输入密码，可选，单次】
7. make download   # 下载最新离线软件包      【可选，可显著加速初始化】
8. make upload     # 将离线软件包上传至元节点
9. make init       # 初始化Pigsty
10. make mon-view   # 打开Pigsty监控首页（默认用户密码：admin:admin）

clean

清理所有的沙箱痕迹（如果有）

1. $ make clean
2. cd vagrant && vagrant destroy -f

up4

执行make up4将调用vagrant up命令，根据Vagrantfile中的定义，使用Virtualbox创建四台虚拟机。

请注意第一次执行vagrant up时，软件会自动从官网下载 CentOS/7 的虚拟机镜像。如果您的网络状况不佳（例如没有FQ代理），则可能需要等待相当长的一段时间。您也可以选择自己创建虚拟机，并根据部署一章的说明进行Pigsty部署（不建议）。

使用 make new4 将执行 make del4; make up4 一次性完成幂等的4节点虚拟机销毁与重新创建工作。

1. $ make up4
2. cd vagrant && vagrant up

ssh

新拉起的虚拟机默认用户为vagrant，需要配置本机到虚拟机的免密ssh访问。执行make ssh命令将调用vagrant的ssh-config命令，将pigsty虚拟机节点的ssh配置文件写入~/.ssh/pigsty_config。

通常该命令只需要在首次启动沙箱时执行一次，后续重新拉起的虚拟机通常会保有相同的SSH配置。

执行完毕后，用户才可以使用类似ssh node-1的方式通过SSH别名连接至沙箱内的虚拟机节点。

1. $ make ssh
2. cd vagrant && vagrant ssh-config > ~/.ssh/pigsty_config 2>/dev/null; true
3. if ! grep --quiet "pigsty_config" ~/.ssh/config ; then (echo 'Include ~/.ssh/pigsty_config' && cat ~/.ssh/config) >  ~/.ssh/config.tmp; mv ~/.ssh/config.tmp ~/.ssh/config && chmod 0600 ~/.ssh/config; fi
4. if ! grep --quiet "StrictHostKeyChecking=no" ~/.ssh/config ; then (echo 'StrictHostKeyChecking=no' && cat ~/.ssh/config) >  ~/.ssh/config.tmp; mv ~/.ssh/config.tmp ~/.ssh/config && chmod 0600 ~/.ssh/config; fi

dns

此命令将Pigsty沙箱虚拟机的静态DNS配置写入/etc/hosts，通常该命令只需要在首次启动沙箱时执行一次。

执行完毕后，用户才可以从本地浏览器使用域名访问 http://g.pigsty 等WebUI。

注意DNS命令需要SUDO权限执行，需要输入密码，因为/etc/hosts文件需要特权方可修改。

1. $ sudo make dns
2. Password: #<在此输入用户密码>
3. if ! grep --quiet "pigsty dns records" /etc/hosts ; then cat files/dns >> /etc/hosts; fi
