MYSQL 创建JOB 折腾过程
常见1045错误
在/etc/my.cnf 中mysqlid 添加:skip-grant-tables
# /etc/init.d/mysql stop
/etc/init.d/mysql start
mysql> UPDATE user SET Password=PASSWORD(’newpassword’) where USER=’root’;
mysql> FLUSH PRIVILEGES;
mysql> quit
# /etc/init.d/mysql restart
# mysql -uroot -p
Enter password: <输入新设的密码newpassword>
mysql>
登录时root无法登录 加个-h试试
mysql -uroot -p123456 -h127.0.0.1
开启JOB 功能
在my.cnf添加mysqlid event_scheduler=ON
表链接的时候需要添加：federated参数
修改后：
[mysqld]
port = 3306
socket = /var/lib/mysql/mysql.sock
skip-locking
key_buffer_size = 16M
max_allowed_packet = 1M
table_open_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
federated
event_scheduler=ON
#skip-grant-tables
下面方法开启后，重启JOB功能又OFF了：
set global event_scheduler=1;
查看JOB 是否开启用以下命令
show global variables like "event_scheduler";
/*建表*/
CREATE TABLE maillog.test(aa VARCHAR(10),bb VARCHAR(10))
用SQLyog
/*建JOB*/
