Specified key was too long; max key length is 767 bytes
Index column size too large. The maximum column size is 767 bytes.
進入到mysql安裝資料庫目錄，找到my.cnf檔案
vi /etc/mysql/my.cnf
在[mysqld]下加入以下配置：
innodb_file_format=barracuda innodb_file_per_table=true innodb_large_prefix=true character-set-server=utf8mb4 collation-server=utf8mb4_unicode_ci max_allowed_packet=500M
修改後配置：
[mysqld] user=mysql # 字符集 character-set-server=utf8 default_authentication_plugin=mysql_native_password #sql_mode=ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION sql_mode=STRICT_TRANS_TABLES,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION # 連線數 max_connections=1500 # 不區分大小寫 lower_case_table_names=1 # 解決問題 maximum column size is 767 bytes. innodb_file_format=barracuda innodb_file_per_table=true innodb_large_prefix=true character-set-server=utf8mb4 collation-server=utf8mb4_unicode_ci max_allowed_packet=500M [client] default-character-set=utf8 [mysql] default-character-set=utf8
重啟資料庫。
再次執行指令碼。
