怎么解決MySQL5.7的mysqldump routines問(wèn)題

本篇內(nèi)容主要講解“怎么解決MySQL5.7的mysqldump routines問(wèn)題”，感興趣的朋友不妨來(lái)看看。本文介紹的方法操作簡(jiǎn)單快捷，實(shí)用性強(qiáng)。下面就讓小編來(lái)帶大家學(xué)習(xí)“怎么解決MySQL5.7的mysqldump routines問(wèn)題”吧!

場(chǎng)景：
1 新建一個(gè)5.7.12的實(shí)例
2 導(dǎo)出全庫(kù)
mysqldump --all-databases -uroot -ptest --set-gtid-purged=off --single-transaction --quick -R --events > /tmp/a.sql
3 導(dǎo)出前檢查：
mysql> select count(*) from mysql.proc;
+----------+
| count(*) |
+----------+
|       47 |
+----------+
1 row in set (0.00 sec)

mysql> select * from  host_summary;
+-----------+------------+-------------------+-----------------------+-------------+----------+-----------------+---------------------+-------------------+--------------+----------------+------------------------+
| host      | statements | statement_latency | statement_avg_latency | table_scans | file_ios | file_io_latency | current_connections | total_connections | unique_users | current_memory | total_memory_allocated |
+-----------+------------+-------------------+-----------------------+-------------+----------+-----------------+---------------------+-------------------+--------------+----------------+------------------------+
| localhost |       1823 | 1.14 s            | 623.98 us             |         468 |     7000 | 714.18 ms       |                   1 |                 7 |            1 | 0 bytes        | 0 bytes                |
+-----------+------------+-------------------+-----------------------+-------------+----------+-----------------+---------------------+-------------------+--------------+----------------+------------------------+
1 row in set (0.04 sec)

4 全庫(kù)導(dǎo)入：
 mysql -uroot -ptest < /tmp/a.sql
 
 5 mysql> select count(*) from mysql.proc;
+----------+
| count(*) |
+----------+
|       0 |
+----------+
1 row in set (0.00 sec)

mysql> select * from sys.host_summary;
ERROR 1356 (HY000): View 'sys.host_summary' references invalid table(s) or column(s) or function(s) or definer/invoker of view lack rights to use them

5.5 5.6中是沒(méi)有這個(gè)問(wèn)題的
因?yàn)樗麄兿到y(tǒng)自帶的沒(méi)有proc.

兩個(gè)方式避免：
1 不導(dǎo)出mysql.proc表
mysqldump --all-databases -uroot -ptest --set-gtid-purged=off --single-transaction --quick -R --events --ignore-table=mysql.proc > /tmp/a.sql
2 導(dǎo)入完成后upgrade

所以，無(wú)論是哪種備份方式，還原好之后最好都要執(zhí)行下upgrade。

另：
使用innobackup的方式?jīng)]有這個(gè)問(wèn)題。

到此，相信大家對(duì)“怎么解決MySQL5.7的mysqldump routines問(wèn)題”有了更深的了解，不妨來(lái)實(shí)際操作一番吧！這里是億速云網(wǎng)站，更多相關(guān)內(nèi)容可以進(jìn)入相關(guān)頻道進(jìn)行查詢(xún)，關(guān)注我們，繼續(xù)學(xué)習(xí)！
