Creating MySQL user ranger2 failed

2021-07-01 18:44:53,480  [E] Creating MySQL user ranger2 failed..

原因是Ranger安装程序默认会使用MySQL的root账号创建所需要的账号，也就是DBA过程。如果不需要安装程序自动创建，则将install.properties中的以下配置前的#号去掉：

setup_mode=SeparateDBA

Specified key was too long; max key length is 767 bytes

修改对应字段的长度可以解决。注意UTF8每个字符4个字节。

去掉prefix key的定义即可。

修改后的建表语句如下：

CREATE TABLE `x_portal_user` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `create_time` datetime DEFAULT NULL,
  `update_time` datetime DEFAULT NULL,
  `added_by_id` bigint(20) DEFAULT NULL,
  `upd_by_id` bigint(20) DEFAULT NULL,
  `first_name` varchar(128) DEFAULT NULL,
  `last_name` varchar(1022) DEFAULT NULL,
  `pub_scr_name` varchar(2048) DEFAULT NULL,
  `login_id` varchar(128) DEFAULT NULL,
  `password` varchar(512) NOT NULL,
  `email` varchar(128) DEFAULT NULL,
  `status` int(11) NOT NULL DEFAULT '0',
  `user_src` int(11) NOT NULL DEFAULT '0',
  `notes` varchar(4000) DEFAULT NULL,
  `other_attributes` varchar(4000) DEFAULT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `x_portal_user_UK_login_id` (`login_id`),
  UNIQUE KEY `x_portal_user_UK_email` (`email`),
  KEY `x_portal_user_FK_added_by_id` (`added_by_id`),
  KEY `x_portal_user_FK_upd_by_id` (`upd_by_id`),
  KEY `x_portal_user_cr_time` (`create_time`),
  KEY `x_portal_user_up_time` (`update_time`),
  KEY `x_portal_user_name` (`first_name`),
  KEY `x_portal_user_email` (`email`),
  CONSTRAINT `x_portal_user_FK_added_by_id` FOREIGN KEY (`added_by_id`) REFERENCES `x_portal_user` (`id`),
  CONSTRAINT `x_portal_user_FK_upd_by_id` FOREIGN KEY (`upd_by_id`) REFERENCES `x_portal_user` (`id`)
) ROW_FORMAT=DYNAMIC;

对整个建表脚本中的SQL都需要对应的修改。
