查看log日志，又百度搜索了很久还是无法解决，最终在google搜索到一篇类似文章找到了灵感，成功解决。
解决方法：
1.使用root登录数据库
root@ada-ubuntu:/var/log/mysql# mysql -uroot -p××××××（注：******为你的数据库root密码）
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 32
Server version: 10.0.31-MariaDB-0ubuntu0.16.04.2 Ubuntu 16.04
Copyright (c) 2000, 2017, Oracle, MariaDB Corporation Ab and others.
Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.
2.输入如下指令
MariaDB [(none)]> show variables like "%char%";
+--------------------------+----------------------------+
| Variable_name | Value |
+--------------------------+----------------------------+
| character_set_client | utf8mb4 |
| character_set_connection | utf8mb4 |
| character_set_database | utf8mb4 |
| character_set_filesystem | binary |
| character_set_results | utf8mb4 |
| character_set_server | utf8mb4 |
| character_set_system | utf8 |
| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.01 sec)
3.退出数据库
MariaDB [(none)]> \q;
Bye
4.
修改/etc/mysql/mariadb.conf.d/目录下的“50-client.cnf 50-mysql-clients.cnf 和50-server.cnf”两个文件，将其中的“utf8mb4”修改为“utf8”再将 /etc/mysql/mariadb.conf.d/50-server.cnf文件中的127.0.0.1修改为0.0.0.0
重启mysql服务
root@ada-ubuntu:/var/log/mysql# vim /etc/mysql/mariadb.conf.d/50-client.cnf
root@ada-ubuntu:/var/log/mysql# vim /etc/mysql/mariadb.conf.d/50-mysql-clients.cnf
root@ada-ubuntu:/var/log/mysql# vim /etc/mysql/mariadb.conf.d/50-server.cnf
root@ada-ubuntu:/var/log/mysql# service mysql restart
5.再次登录mysql查看
root@ada-ubuntu:/var/log/mysql# mysql -uroot -p******

| character_sets_dir | /usr/share/mysql/charsets/ |
+--------------------------+----------------------------+
8 rows in set (0.00 sec)
可看出都已修改为utf8编码
6.将数据库database删除重建，授权
MariaDB [(none)]> drop database glance;
Query OK, 0 rows affected (0.03 sec)
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| information_schema |
| keystone |

+--------------------+
4 rows in set (0.01 sec)
MariaDB [(none)]> create database glance;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> show databases;
+--------------------+
| Database |
+--------------------+
| glance |
| information_schema |

+--------------------+
5 rows in set (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'localhost' IDENTIFIED BY '密码';
Query OK, 0 rows affected (0.05 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON glance.* TO 'glance'@'%' IDENTIFIED BY '密码';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> \q;
Bye
7.最后重新执行su -s /bin/sh -c "glance-manage db_sync" glance指令，成功！
root@ada-ubuntu:/var/log/mysql# su -s /bin/sh -c "glance-manage db_sync" glance
