私有云搭建Discourse 博客系统

私有云搭建 Discourse 博客系统

1. 前期准备

一台配置合适的服务器(笔记本也可)，装有Ubuntu1804。机器配置局域网 IP: 192.168.10.XXX, 机器的ip 对应配置域名：discourse.test.com

hostname	ip地址	cpu	内存	磁盘	系统版本	域名
discourse	192.168.0.175	4c	4g	20g	ubuntu1804	discourse.test.com

登录到系统:

 ssh discourse@192.168.0.175
sudo apt update
sudo apt upgrade -y

2. 准备部署文件

 sudo -s  #为root用户方便后续工作，因此首先切换到root shell
mkdir /var/discourse  # 接下来，创建/var/discourse目录，所有与Discourse相关的文件都在此目录下。
git clone https://github.com/discourse/discourse_docker.git /var/discourse #将官方Discourse Docker Image复制到/var/discourse
cd /var/discourse
ls

3. 配置和引导Discourse

从这里，您可以启动安装脚本。

 cd /var/discourse
./discourse-setup

您将被问到以下问题：

Discourse的主机名？

输入您要用于Discourse的主机名，例如，discourse.test.com，其中discourse.test.com可以用您的域名替换。您需要使用一个域名，因为发送电子邮件时不能用IP地址。

管理员帐户的电子邮件地址？

选择要用于Discourse管理员帐户的电子邮件地址。这个电子邮件地址可以与您的Discourse域名完全无关，可以是您的电子邮件地址。

请注意，当第一个用户注册该电子邮件时，此电子邮件地址将默认成为Discourse管理员。稍后当您从其网络控制面板设置Discourse时，您还需要此电子邮件地址。

 Hostname for your Discourse? [discourse.example.com]:
Email address for admin account(s)? [me@example.com,you@example.com]:
SMTP server address? [smtp.example.com]:
SMTP port? [587]:
SMTP user name? [user@example.com]:
SMTP password? [pa$$word]:
Let's Encrypt account email? (ENTER to skip) [me@example.com]:

这里需要您填写您的邮箱相关信息，您可以参考您邮箱的相关设置。

最后，系统会要求您确认刚刚输入的所有设置。确认设置后，脚本将生成一个调用的配置文件app.yml，然后启动引导。

注意：如果您需要在引导后更改或修复这些设置，请编辑/containers/app.yml文件并运行./launcher rebuild app否则，您的更改将不会生效。

引导需要2-8分钟，之后将会运行。现在，让我们继续创建一个管理员帐户。

4. 注册管理员帐户

在您的浏览器中访问您的Discourse域名，你将看到下面的页面。

如果您收到502 Bad Gateway错误，请等一两分钟然后刷新重试，Discourse可能尚未完成安装。

页面加载时，单击蓝色注册按钮。您将看到一个名为“注册管理员帐户”的页面，其中包含以下字段：

电子邮件：从下拉菜单中选择您之前提供的电子邮件地址。

用户名：选择用户名。

密码：设置一个强密码。

然后单击表单上的蓝色“注册”按钮提交。您将看到一个对话框，显示确认您的电子邮件。检查收件箱中的确认电子邮件。如果您没有收到，请尝试单击“重新发送激活电子邮件”按钮。

注册管理员帐户后，安装向导将启动并引导您完成Discourse的基本配置。您现在可以浏览它或单击“稍后”跳过。

有时候由于邮件设置问题无法收到注册邮件可以如下操作：

后台创建admin账户

1.在cd /var/discourse 下执行：

 ./launcher enter app #进入容器
rake admin:create
Email:  duanshuaixing@gmail.com
Password:  
Repeat password:  
Do you want to grant Admin privileges to this account? (Y/n)  Y

创建成功，请记住设置的密码和邮箱，然后再次打开论坛网址，发现已经进入了论坛首页

5. 修改配置文件

更改或修复这些设置，请编辑/var/discourse/containers/app.yml文件并运行./launcher rebuild app否则，您的更改将不会生效。

6. 支持https

修改app.yml

 /var/discourse/containers/app.yml内修改打开这个注释
- "templates/web.ssl.template.yml"

生成证书并导入证书

生成证书参考Certbot自签Let’s Encrypt证书

 mkdir -p /var/discourse/shared/standalone/ssl/
cp ssl.crt /var/discourse/shared/standalone/ssl/ssl.crt
cp ssl.key /var/discourse/shared/standalone/ssl/ssl.key

重建app
```
 ./launcher rebuild app
```
开启强制https
重启应用
```
 ./launcher restart app
```

7. 安装插件

 ./launcher enter app
cd /var/www/discourse/
rake plugin:install repo=https://github.com/unfoldingWord-dev/discourse-mermaid.git
rake plugin:install repo=https://github.com/albertchan/discourse-aliyun-oss.git
rake assets:precompile
exit
./launcher restart app

8. 备份和恢复

备份
恢复，下载的备份导入到另外一个环境

 mkdir -p /var/discourse/shared/standalone/backups/default
scp root@192.168.0.175:/var/discourse/shared/standalone/backups/discourse-2021-04-21-151816-v20210328233843.tar.gz /var/discourse/shared/standalone/backups/default
 
cd /var/discourse
./launcher enter app
discourse enable_restore
discourse restore discourse-2021-04-21-151816-v20210328233843.tar.gz

9. 卸载

 cd /var/discourse
./launcher destroy app
rm -rf /var/discourse/

10. FAQ

构建项目git clone慢可以通过给容器配置vpn或者代理方式解决，建议sshuttle 方式，比较方便

用sshuttle 配置连接香港精品线路ecs，-x是排除在隧道外的地址，47.57.14.232是香港ecs，172.17.188.0/24是香港ecs 主机网段、172.18.0.0/16是容器网段

 sshuttle -l 0.0.0.0:0 -r root@47.57.14.232 -x 47.57.14.232 -x 127.0.0.1 -x 172.18.0.0/16 -x 172.17.188.0/24 0/0 --dns

代理搭建参考：https://blog.csdn.net/weixin_47003048/article/details/108436853

docker配置代理

 mkdir ~/.docker
cat ~/.docker/config.json
{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://47.57.14.232:8080",
     "httpsProxy": "http://47.57.14.232:8443",
     "noProxy": "127.0.0.1,localhost,172.17.0.0/16,192.168.0.0/24,gems.ruby-china.com
   }
 }
}
 
 
systemctl daemon-reload
systemctl restart docker
 
cd /var/discourse
./launcher bootstrap app
./launcher start app
