1.第一步，准备好一台VPS，内存最好别低于 1G，如果没有VPS，可以【点击前往】创建！

2.准备好一个域名，收费免费的都可以，比如我使用子域名：bbs.freedidi.com ，将其解析到VPS的ip地址上;

3.连接VPS，进入终端进行安装，安装命令如下：

sudo apt install docker.io

sudo apt install docker.io sudo apt install git

sudo apt install docker.io
sudo apt install git

安装 Discourse

git clone https://github.com/discourse/discourse_docker.git /var/discourse

sudo -s git clone https://github.com/discourse/discourse_docker.git /var/discourse cd /var/discourse chmod 700 containers

sudo -s
git clone https://github.com/discourse/discourse_docker.git /var/discourse
cd /var/discourse
chmod 700 containers

执行安装:

./discourse-setup

安装过程中需要填写的信息

如果需要修改配置：

只需进入并修改该文件： var/discourse/containers/app.yml

修改后进行重启容器即可：

cd /var/discourse ./launcher destroy app ./launcher start app

cd /var/discourse
./launcher destroy app
./launcher start app
