2、具體從庫同步異常信息

3、查看表結構
root@localhost: 15:22 [7313][gomepush]>show create table test_tbl\G; *************************** 1. row *************************** Table: push_template Create Table: CREATE TABLE `push_template` ( `infoId` int(32) NOT NULL AUTO_INCREMENT, `name` varchar(258) DEFAULT NULL, `templateDes` varchar(512) DEFAULT NULL, `chanel` varchar(32) DEFAULT NULL, `id` varchar(32) DEFAULT NULL, `title` varchar(258) CHARACTER SET utf8mb4 DEFAULT NULL, `content` varchar(1024) CHARACTER SET utf8mb4 DEFAULT NULL, `scheme` varchar(258) DEFAULT NULL, `showType` varchar(258) DEFAULT NULL, `pushImg` varchar(258) DEFAULT NULL, `centreImg` varchar(258) DEFAULT NULL, `expire` int(32) DEFAULT NULL, `userId` varchar(258) DEFAULT NULL, `state` varchar(32) DEFAULT NULL, `centreType` varchar(258) DEFAULT NULL, `createTime` datetime DEFAULT NULL, `updateTime` datetime DEFAULT NULL, `userCode` varchar(258) DEFAULT '' COMMENT '用戶編號', PRIMARY KEY (`infoId`), UNIQUE KEY `id_unique` (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=91 DEFAULT CHARSET=utf8 1 row in set (0.01 sec) ERROR: No query specified
已經存在該字段。
4、從庫信息如下
Retrieved_Gtid_Set: 276909df-1105-11e6-81d8-6c92bf177322:495803940-566707006, 4f9ba386-1103-11e6-81cc-6c92bf176998:2079168114-2079168115, 896178f5-cb1b-11ea-949e-94292f719203:1-102022 Executed_Gtid_Set: 276909df-1105-11e6-81d8-6c92bf177322:495803940-566675454, 4f9ba386-1103-11e6-81cc-6c92bf176998:2079168114, 896178f5-cb1b-11ea-949e-94292f719203:1-102022, 89757714-cb1b-11ea-949e-94292f719173:1-518 Auto_Position: 1
從這里看，由于環(huán)境不干凈，導致信息難以確認。所以極力推薦，從主庫解析binlog日志來確定gtid的信息。
5、在主庫中解析從庫報錯信息的日志
# 在主庫中解析binlog日志 /app/mysql/bin/mysqlbinlog --base64-output=DECODE-ROWS -v --start-position=84720542 /data/my3306/data/mysql-bin.000482 | more DELIMITER /*!*/; # at 84720542 #220223 15:10:16 server id 461597306 end_log_pos 84720590 CRC32 0x6166919b GTID [commit=yes] SET @@SESSION.GTID_NEXT= '4f9ba386-1103-11e6-81cc-6c92bf176998:2079168115'/*!*/; # at 84720590 #220223 15:10:16 server id 461597306 end_log_pos 84720792 CRC32 0xcc7102b3 Query thread_id=992913 exec_time=1 error_code=0 use `testdb`/*!*/; SET TIMESTAMP=1645600216/*!*/; SET @@session.pseudo_thread_id=992913/*!*/; SET @@session.foreign_key_checks=1, @@session.sql_auto_is_null=0, @@session.unique_checks=1, @@session.autoco mmit=1/*!*/; SET @@session.sql_mode=1073741824/*!*/; SET @@session.auto_increment_increment=1, @@session.auto_increment_offset=1/*!*/; /*!\C utf8 *//*!*/; SET @@session.character_set_client=33,@@session.collation_connection=33,@@session.collation_server=33/*!*/; SET @@session.lc_time_names=0/*!*/; SET @@session.collation_database=DEFAULT/*!*/; ALTER TABLE `test_tbl` ADD COLUMN `userCode` varchar(258) NULL DEFAULT '' COMMENT '用戶編號' AFTER `upda teTime` /*!*/;
重點關注： SET @@SESSION.GTID_NEXT= '4f9ba386-1103-11e6-81cc-6c92bf176998:2079168115'/*!*/;
6、解決辦法
STOP SLAVE; SET @@SESSION.GTID_NEXT= '4f9ba386-1103-11e6-81cc-6c92bf176998:2079168115'; BEGIN; COMMIT; SET SESSION GTID_NEXT = AUTOMATIC; START SLAVE;
