Dify本地安装

目录

方式一docker安装：

方式二源码安装：

Dify本地安装可以用docker方式，和源码编译方式。

先到云厂商平台申请一台Centos系统云主机，网络选择海外，需要公网IP，再按一下流程操作：

方式一docker安装：

安装docker compose：https://blog.csdn.net/weixin_56781779/article/details/132258636

安装dify并启动：

git clone https://github.com/langgenius/dify.gitcd dify/dockerexport EXPOSE_NGINX_PORT=8080docker compose up -d

启动后docker ps 可以看到以下容器

netstat -natp可以看到docker监听的端口是8080，设置安全组开发8080端口

访问 http://虚拟机ip:8080  根据情况输邮箱，用户名，密码 完成本地注册可以开始使用

方式二源码安装：

源码安装主要可以参考文档

https://docs.dify.ai/zh-hans/getting-started/install-self-hosted/local-source-code

文档里有一些要调整的地方：

安装数据库：

sudo apt-get update#安装pg redis
sudo apt install redis-server wget postgresql postgresql-client -ysudo apt install nginx nodejs npm -ysudo wget https://github.com/weaviate/weaviate/releases/download/v1.27.12/weaviate-v1.27.12-linux-amd64.tar.gzsudo tar -zxf weaviate-v1.27.12-linux-amd64.tar.gz#安装向量数据库
sudo chmod +x weaviatesudo mv weaviate /opt

设置数据库密码：

修改/etc/redis/redis.conf，添加：requirepass difyai123456

启动redis：

service redis-server start

启动pg：

service postgresql start 

修改pg密码：

su - postgrespsqlCREATE DATABASE dify;ALTER USER postgres WITH PASSWORD 'difyai123456';quit;

启动weaviate：

export PERSISTENCE_DATA_PATH=/var/lib/weaviate
export QUERY_DEFAULTS_LIMIT=25
export AUTHENTICATION_ANONYMOUS_ACCESS_ENABLED=false
export DEFAULT_VECTORIZER_MODULE=none
export CLUSTER_HOSTNAME=node1
export AUTHENTICATION_APIKEY_ENABLED=true
export AUTHENTICATION_APIKEY_ALLOWED_KEYS=WVF5YThaHlkYwhGUSmCRgsX3tD5ngdN8pkih
export AUTHENTICATION_APIKEY_USERS=[e-mail]
export AUTHORIZATION_ADMINLIST_ENABLED=true
export AUTHORIZATION_ADMINLIST_USERS=[e-mail] /opt
nohup ./weaviate --host 0.0.0.0 --port '8080' --scheme http |tee ./weaviate.log 2>&1 &

再按照文档进行源码安装，文档中

如果执行poetry shell失败的话以下命令要带上poetry run，否则会报错

poetry run flask db upgrade

启动前端，后端，和worker

#启动前端
export NEXT_PUBLIC_DEPLOY_ENV=DEVELOPMENT
export NEXT_PUBLIC_EDITION=SELF_HOSTED
export NEXT_PUBLIC_API_PREFIX=/console/api  #不设置默认访问http://localhost/console/api
export NEXT_PUBLIC_PUBLIC_API_PREFIX=/api  #不设置默认访问http://localhost/api
export NEXT_PUBLIC_SENTRY_DSN=
export NEXT_TELEMETRY_DISABLED=1
export NEXT_PUBLIC_UPLOAD_IMAGE_AS_ICON=false
export NEXT_PUBLIC_TEXT_GENERATION_TIMEOUT_MS=60000
export NEXT_PUBLIC_CSP_WHITELIST=
export NEXT_PUBLIC_TOP_K_MAX_VALUE=10
export NEXT_PUBLIC_INDEXING_MAX_SEGMENTATION_TOKENS_LENGTH=4000
nohup npm run start &#启动worker
#start backend
export CONSOLE_API_URL=
export APP_API_URL=
export WEB_SENTRY_DSN=
export NEXT_TELEMETRY_DISABLED=0
export TEXT_GENERATION_TIMEOUT_MS=60000
export CSP_WHITELIST=
export TOP_K_MAX_VALUE=10
export INDEXING_MAX_SEGMENTATION_TOKENS_LENGTH=4000
cd /app/dify/api
nohup poetry run  celery -A app.celery worker -P gevent -c 1 -Q dataset,generation,mail,ops_trace --loglevel INFO ./celery.log 2>&1 &nohup poetry run flask run --host 0.0.0.0 --port=5001 --debug |tee ./backend.log 2>&1 &

这样跑起来只适合本机访问，如果要从公网访问还要假一层nginx，我们在前面已安装nginx，这里我们就配置nginx，让其可以代理访问dify

修改/etc/nginx/nginx.conf如下：

user www-data;
worker_processes auto;
pid /run/nginx.pid;
error_log /var/log/nginx/error.log;
include /etc/nginx/modules-enabled/*.conf;events {worker_connections 768;# multi_accept on;
}http {include       /etc/nginx/mime.types;default_type  application/octet-stream;log_format  main  '$remote_addr - $remote_user [$time_local] "$request" ''$status $body_bytes_sent "$http_referer" ''"$http_user_agent" "$http_x_forwarded_for"';access_log  /var/log/nginx/access.log  main;sendfile        on;#tcp_nopush     on;keepalive_timeout  65;#gzip  on;client_max_body_size 15M;include /etc/nginx/conf.d/*.conf;
}

修改文件 /etc/nginx/conf.d/default.conf

server {listen 8080;server_name _;location /console/api {proxy_pass http://127.0.0.1:5001;}location /api {proxy_pass http://127.0.0.1:5001;}location /v1 {proxy_pass http://127.0.0.1:5001;}location /files {proxy_pass http://127.0.0.1:5001;}location / {proxy_pass http://127.0.0.1:3000;}}

重启nginx：systemctl restart nginx

通过命令netstat -natp 确认nginx确实监听8080端口

访问 http://虚拟机ip:8080  后续页面访问同方式一
