发布时间:2020-07-27编辑:脚本学堂
本文介绍了mysql数据库设置自动启动的方法,有需要的朋友参考下。

1,检查当前的job
 

复制代码 代码示例:

mysql> use dev;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> show events;
+-----+-------------+------------------+-----------+-----------+------------+----------------+----------------+---------------------+------+---------+------------+----------------------+----------------------+--------------------+
| Db  | Name        | Definer          | Time zone | Type      | Execute at | Interval value | Interval field | Starts              | Ends | Status  | Originator | character_set_client | collation_connection | Database Collation |
+-----+-------------+------------------+-----------+-----------+------------+----------------+----------------+---------------------+------+---------+------------+----------------------+----------------------+--------------------+
| dev | my_job_test | hxl@192.168.56.% | SYSTEM    | RECURRING | NULL       | 1              | DAY            | 2014-03-07 18:10:00 | NULL | ENABLED |          0 | utf8                 | utf8_general_ci      | latin1_swedish_ci  |
+-----+-------------+------------------+-----------+-----------+------------+----------------+----------------+---------------------+------+---------+------------+----------------------+----------------------+--------------------+
1 row in set (0.23 sec)

2,检查是否开启了自动启动
 

复制代码 代码示例:
mysql> show global variables like '%event_scheduler%';
+-----------------+-------+
| Variable_name   | Value |
+-----------------+-------+
| event_scheduler | OFF   |
+-----------------+-------+
1 row in set (0.00 sec)

3,设置job自动启动
 

复制代码 代码示例:
mysql> set global event_scheduler = on;
Query OK, 0 rows affected (0.00 sec)

4,设置mysql重启后,job能自动启动
编辑/etc/my.cnf文件,在[mysqld]下添加event_scheduler=1
 

复制代码 代码示例:

[root@node1 etc]# more my.cnf
[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
# Disabling symbolic-links is recommended to prevent assorted security risks
symbolic-links=0
event_scheduler=1

[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
