在等待服务容器稳定的[300]秒后，Keyloak MySQL安装程序失败，并出现错误&超时。操作将回滚。&Q； [英] Keycloak MySQL setup failed with error "Timeout after [300] seconds waiting for service container stability. Operation will roll back."

问题描述

我尝试了8.x和10.x版本的Keycloak，也尝试了Keycloak坞站图像，但遇到了下面的问题，同时使用MySQL配置Keycloak

使用命令增加超时

$ bin/standalone.sh -Djboss.as.management.blocking.timeout=3600

失败，错误如下

我正在寻找类似以下内容的解决方案：

1. 如果我可以获得Keyloak的初始DDL和amp；DML
2. 如果密钥罩可以从失败的位置继续
3. 是否可以增加超时。在这种情况下，我尝试了以下命令，但不起作用

docker run -p 8080:8080 -e KEYCLOAK_USER=admin -e KEYCLOAK_PASSWORD=password -e DB_VENDOR=mysql -e DB_DATABASE=keycloak -e DB_USER=keycloak -e DB_PASSWORD=keycloak -e DB_ADDR=mysql -e ROOT_LOGLEVEL=DEBUG -e JAVA_OPTIONS="-Djboss.as.management.blocking.timeout=900" -e KEYCLOAK_LOGLEVEL=DEBUG --link=mysql jboss/keycloak

推荐答案

我今天遇到此问题，因为我的KeyCloak实例突然停止工作。

我查看了我的底层PostgreSQL数据库并检索到锁。 我看到的是，Liquibase锁没有释放。

所以我使用此命令在PostgreSQL DB中搜索打开的活动：

SELECT pid, state, username, query, query_start
FROM pg_stat_activity
WHERE pid in (
  select pid from pg_locks l
  join pg_class t on l.relation = t.oid
  where t.relkind = 'r'
);

返回以下内容：

pid | state  | usename  |                                query                                 |          query_start
-----+--------+----------+----------------------------------------------------------------------+-------------------------------
  32 | active | keycloak | SELECT ID FROM public.databasechangeloglock WHERE ID=1000 FOR UPDATE | 2020-10-11 14:21:07.396058+00
 354 | active | keycloak | SELECT ID FROM public.databasechangeloglock WHERE ID=1000 FOR UPDATE | 2020-10-11 19:42:06.636659+00

这些数据库锁来自Liquibase，Keycloak使用它来升级您的数据结构/定义。升级架构时未释放这些锁。

删除该表后，该服务现在再次工作。

DROP TABLE databasechangeloglock;

在我的情况下，增加阻塞超时和向事务管理器添加默认超时都不起作用。

<coordinator-environment default-timeout="600" .../> # did not work
...
JAVA_TOOLS_OPTS: "-Djboss.as.management.blocking.timeout=3600" # did not work

这篇关于在等待服务容器稳定的[300]秒后，Keyloak MySQL安装程序失败，并出现错误&超时。操作将回滚。&Q；的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
