1. Why I wrote install-steemd.sh? / 为什么我要会编写这个安装脚本?
I registered steemit one week ago. I wrote 6 posts in these days and got many upvotes and STEEM, I am very happy. So I decided to create a steem node for studying more knowledge.
When I tried to compile & install steemd, I searched different HOWTO guides, unfortunately, I experienced many failures. Finally I made it on Ubuntu 16.04 LTS x64, so I decided to write this guide, and build the installion codes into a single script - install-steemd.sh.
我在一周前刚刚成功注册到 steemit，是一个不折不扣的新手。这些天，我发了6篇文章，结果得到了非常多的点赞，也赚到了不少 STEEM 币奖励。这让我更有动力去深入研究 Steem。为此我决定自建一个 Steem 节点。
然而，当我搜索了网上各种教程，尝试编译和安装 steemd 的时候，却遭遇了数次失败。当然，最后我还是在 Ubuntu 16.04 LTS x64 搞定了这一切。于是我将安装的详细过程，做成了一键安装脚本 install-steemd.sh，方便大家使用。
2. Compiling & Installiaon Requirement / 安装需求
To compile and install steed, the min memory of 4GB is required. I got failure when I first compiled on an Aliyun 2GB VPS. Finally, I successfully compiled steemd on a Linode 4GB VPS. because Linode is very cheap. Here is a comparison.
要成功编译和安装 steem, 至少需要 4GB 内存。刚开始我不知道这个限制，在阿里云的 2GB VPS 上编译，结果失败了好多次。最终我将 steemd 成功安装在一台Linode 4GB VPS 上了，因为它足够便宜。下面是一个比较图表:
| VPS | Mem | Price/mo |
|---|---|---|
| Linode | 4 GB | 20 USD |
| DigitalOcean | 4 GB | 40 USD |
| Aliyun | 4 GB | 8 USD /319 CNY |
3. Guide for purchasing Linode VPS / Linode VPS 购买教程
If you have a Linux VPS and installed Ubuntu 16.04 LTS x64 already, please ignore this step.
如果你拥有一台已经安装了 Ubuntu 16.04 LTS x64 的 Linux VPS，则可以无视此步骤。
- Visit Linode.com, click Pricing on the top. Select Linode 4GB in pricing page, then check out it.
访问 Linode.com, 点击顶部的 Pricing. 然后在 Pricing 页面选择 Linode 4GB, 然后付款完成购买即可。这个细节过程不再详述。 - After completed the purchasing, click Linodes -> Rebuild, Select 64 bit Ubuntu 16.04 LTS in Image filed, and set a root password, then click Rebuild button.
成功完成购买之后，点击 Linodes -> Rebuild, 然后在 Image 字段中，选择 64 bit Ubuntu 16.04 LTS, 并在 Root Password 设置好 root 密码，点击 Rebuild 按纽即可
- Click Dashboard, and then click Reboot button. When all complated, the Host Job Queue will show "Success System Boot" as below screenshot:
点击 Dashboard, 然后点击 Reboot 按钮。如果一切正常，那么 Host Job Queue 一这节，将会显示 "Success System Boot" 字样，如下图所示：
- Click Remote Access, you will get the public IP of your Linode VPS. Then you can use this IP and root password to login into your Linide via a SSH client. I recommend Putty.
点击 Remote Access，你将获取此 Linode VPS 的公网 IP。然后，你可以使用此 IP 以及之前设置的 root 密码，通过 SSH 客户端登录到你的 VPS。我推荐使用 Putty。
4. Easy Compile & install steemd on Ubuntu 16.04 / 使用一键安装脚本轻松安装 steemd
When you logined into your VPS, just copy below scripts and then paste them on SSH shell:
登录成功之后，复制下列脚本到 SSH Shell 窗口即可:
wget https://www.xiaohui.com/imglib2/i1650/id1672/install-steemd.sh
chmod 0777 install-steemd.sh
./install-steemd.sh
Note: Below is the contents of install-steemd.sh. If my site www.Xiaohui.com is down, you can also copy & paste them to a local file, upload it to your VPS, then launch it.
注意：下面就是 install-steemd.sh 的脚本内容。如果我的网站 www.Xiaohui.com 当机了，你也可以将其复制并保存到一个本地文件，然后上传到你的 VPS，直接执行即可。

- If you won't become a miner, and want to launch it as a steem node only, please launch below command:
如果你不想挖矿，仅仅想提供一个 Steem 节点，请运行下列命令:
nohup /root/steemd/steemd&
You can also add above command to file /etc/rc.local. It will be auto launched in background after Ubuntu rebooted. Note: I used full path in this section. If you steemd is not located in /root/steemd, please replace it.
同时，你也可以将上述命令，加入到 /etc/rc.local，将它会随系统重启而自动运行。注意：在这一节，我使用了绝对路径。如果你的 steemd 没有在 /root/steemd/ 目录，请注意替换它们。下同。 - If you want to become a miner, please launch below command(Do not forget to set your account and password):
如果你想成功矿工，请执行下列命令（注意设好帐号和密码)
/root/steemd/steemd —miner='["accountname","${WIFPRIVATEKEY}"]' —witness='"accountname"' —seed-node="52.38.66.234:2001" —mining-threads=2
