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.git
cd dify/docker
export EXPOSE_NGINX_PORT=8080
docker 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 -y
sudo apt install nginx nodejs npm -y
sudo wget https://github.com/weaviate/weaviate/releases/download/v1.27.12/weaviate-v1.27.12-linux-amd64.tar.gz
sudo tar -zxf weaviate-v1.27.12-linux-amd64.tar.gz
#安装向量数据库
sudo chmod +x weaviate
sudo 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 - postgres
psql
CREATE 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=hello@dify.ai
export AUTHORIZATION_ADMINLIST_ENABLED=true
export AUTHORIZATION_ADMINLIST_USERS=hello@dify.ai
cd /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
