用Mastodon搭建自己的Twitter

简介

• Mastodon是一款‘去中心化’的开源社交软件，类似Twitter和新浪微博

• 可以建立独立节点，也可以跨节点交流

机器环境

• CentOS7

• Docker 18.06.1-ce

• Docker-compose 1.22

• Git

• Nginx

下载项目代码

cd /home/
git clone https://github.com/tootsuite/mastodon.git live
cd live
chown -R 991:991 public

编辑 docker-compose.yml

vi docker-compose.yml

# 去掉redis和postgresql的持久化的注释，使其可以持久化数据

拉取镜像

docker pull tootsuite/mastodon

配置域名/数据库/邮件系统/管理员账户

docker-compose run --rm web bundle exec rake mastodon:setup

# domain：填自己的域名，这里是192.168.88.104
# 不要使用localhost发邮件，用mailgun的STMP服务
# 记得选保存配置选yes
# 开始初始化数据库选选yes
# 预编译选yes
# 初始化管理员账户选yes

配置Nginx

• vi /etc/nginx/conf.d/mysite.conf

• 只需修改root为代码的目录即可，其它地方都不用改

• 启动Nginx：nginx -c /etc/nginx/nginx.conf

启动Mastodon

cd /home/live
docker-compose up -d

• 启动后访问：https://192.168.88.104 (注意这里为之前设置的域名)

常见问题

• 不能上传图片：

• • 必须保证/live/public/system的所属组是991

  • chown -R 991:991 /home/live/public/system
