我在以独立群集模式设置Keycloak服务器时遇到了一些配置问题.尽管配置数据源以使用postgres数据库{REMOTE_IP},但它无法启动服务器抱怨它无法连接localhost:5432.

我一直在搜索,但是我很困惑为什么当connection-url设置为远程主机时,DataSource会尝试连接到localhost.

我的配置有什么错误吗？我怎样才能弄清楚为什么PG试图连接到localhost而不是{REMOTE_IP}

我的设置是1个Postgres数据库服务器和2个Keycloak服务器

我按照安装说明使用了关系数据库,并为Postgres添加了JDBC驱动程序v9.4.1212.

我的DataSource配置如下:

<datasource jndi-name="java:jboss/datasources/KeycloakDS" pool-name="KeycloakDS" enabled="true" use-java-context="true">
    <connection-url>jdbc:postgresql://{REMOTE_IP}:5432/keycloak</connection-url>
    <driver>postgresql</driver>
    <pool>
        <max-pool-size>20</max-pool-size>
    </pool>
    <security>
        <user-name>keycloak</user-name>
        <password>{PASSWORD}</password>
    </security>
</datasource>

日志中的错误消息显示为:
