简介
Keycloak 是一款开源的身份验证程序，具备以下的特点：
- 影响最小的方式为应用程序添加身份验证
- 不存储用户数据和验证数据
- 提供用户联合、高强度认证、用户管理、细粒度授权等功能
创建数据库
使用的数据库是 postgresql，假设已经有安装好的 postgresql，并且默认管理员账号是 postgres，那么我们先创建 keycloak 的用户。数据库的详细操作可以参考：PGSQL 安装配置指南
su - postgres # 我们创建一个名为 keycloak 的 pgsql 用户和名为 keycloak 的数据库 createuser -s -P keycloak createdb keycloak -O keycloak
