Linux服务器上部署dify，处理报错信息

说明：系统版本：Linux 4.19.90-89.11.v2401.ky10.x86_64 GNU/Linux
假设当前最新版本为 1.4.3（2025年6月19日日期的最新版本）
1、下载原代码

git clone https://github.com/langgenius/dify.git --branch 1.4.3

也可以去https://github.com/langgenius/dify/tree/main/ 这个地址下载源码
2、复制环境变量，不用修改
进入 Dify 源代码的 Docker 目录

cd dify/docker
cp .env.example .env

3、启动dify服务

docker-compose up -d

需要先安装docker
再安装docker-compose，可以如下安装：

curl -L "https://github.com/docker/compose/releases/download/v2.20.3/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

注：启动会去拉取相应的包，如果拉取失败添加docker的配置。

vi /etc/docker/daemon.json 
{
"registry-mirrors": ["https://docker.registry.cyou",
"https://docker-cf.registry.cyou",
"https://dockercf.jsdelivr.fyi",
"https://docker.jsdelivr.fyi",
"https://dockertest.jsdelivr.fyi",
"https://mirror.aliyuncs.com",
"https://dockerproxy.com",
"https://mirror.baidubce.com",
"https://docker.m.daocloud.io",
"https://docker.nju.edu.cn",
"https://docker.mirrors.sjtug.sjtu.edu.cn",
"https://docker.mirrors.ustc.edu.cn",
"https://mirror.iscas.ac.cn",
"https://docker.rainbond.cc"]
}

再次启动，会看到如下的信息：

[+] Running 12/12

 ✔ Network docker_default             Created 
 ✔ Container docker-redis-1           Started

 ✔ Container docker-plugin_daemon-1   Started

4、登录，如果没有修改端口，默认是80
http://IP地址/install ，如果登录一直转动，不出现页面，说明报错了，后台查看日志：

docker-compose logs -f

注册相应的管理员账号。

如果报错：

Aborted!
Running migrations
OpenBLAS blas_thread_init: pthread_create failed for thread 1 of 12: Operation not permitted
OpenBLAS blas_thread_init: RLIMIT_NPROC 510383 current, 510383 max

docker-api-1 exited with code 1
docker-sandbox-1 exited with code 2

可以在dify/docker/docker-compose.yaml
在worker、api、sandbox下面添加如下配置：

services:
  worker:
    ulimits:
      nproc: 65535  # 允许容器内更多进程/线程
    security_opt:
      - seccomp:unconfined  # 禁用默认的安全策略
  api:
    ulimits:
      nproc: 65535
    security_opt:
      - seccomp:unconfined

  sandbox:
    ulimits:
      nproc: 65535
    security_opt:
      - seccomp:unconfined

再次重启
docker-compose down && docker-compose up -d
打开页面，就正常了。
