Centos7 安装 Nacos2.0 数据库导入sql文件的坑

mysql5.6.44 导入 nacos-mysql.sql 文件报错

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

修改 nacos-mysql.sql

```
    CREATE TABLE `permissions` (
        `role` varchar(50) NOT NULL,
        `resource` varchar(255) NOT NULL,
        `action` varchar(8) NOT NULL,
        UNIQUE INDEX `uk_role_permission` (`role`,`resource`,`action`) USING BTREE
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='permissions';


    CREATE TABLE `roles` (
        `username` varchar(50) NOT NULL,
        `role` varchar(50) NOT NULL,
        UNIQUE INDEX `idx_user_role` (`username` ASC, `role` ASC) USING BTREE
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='roles';

    CREATE TABLE `users` (
        `username` varchar(50) NOT NULL PRIMARY KEY,
        `password` varchar(500) NOT NULL,
        `enabled` boolean NOT NULL
    ) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_bin COMMENT='users';

```

清空数据库重新导入就好了！！！
