不常用的第三方服务集成

1.ldap

1.1.ldap服务搭建

docker方式搭建：包含了ldap服务和ldap admin图形化界面服务

参考ldap服务：http://127.0.0.1:81
用户名：CN=admin,DC=ldap,DC=com 密码：123456

docker-compose.yml文件内容如下

version: '3'

services:
  ldap:
    image: osixia/openldap:latest
    container_name: ldap
    environment:
      - TZ=Asia/Shanghai
      - LDAP_ORGANISATION=ldap
      - LDAP_DOMAIN=ldap.com
      - LDAP_ADMIN_PASSWORD=Admin100%
    ports:
      - 389:389
      - 636:636
    networks:
      - ldap-net
  
  ldapui:
    image: osixia/phpldapadmin:latest
    container_name: ldapui
    privileged: true
    environment:
      - TZ=Asia/Shanghai
      - PHPLDAPADMIN_HTTPS=false
      - PHPLDAPADMIN_LDAP_HOSTS=ldap
    ports:
      - 1443:443
      - 81:80
    depends_on:
      - ldap
    networks:
      - ldap-net

networks:
  ldap-net:
    driver: bridge

2.sftp

2.1.sftp服务搭建

docker-compose方式搭建

version: '3'

services:
  sftp:
    image: atmoz/sftp
    volumes:
      - ./test/:/home/foo/
    ports:
      - "2222:22"
    privileged: true
    command: foo:123456:1002

镜像作者的设定应该是把映射目录作为根目录（监狱），根目录（./test）是不能有写权限的，需要在下面再建一个子目录.

./test文件夹授权755，在test目录下再新建一个文件夹，比如upload, 把需要上传的文件放置在upload中，并且修改upload权限为777，例如：

mkdir upload

chmod 777 upload
