  • MySQL常见报错汇总

    1>.ERROR 1290 (HY000): The MySQL server is running with the --secure-file-priv option so it cannot execute this statement

      报错原因:

        在MySQL的配置文件中未指定“--secure-file-priv”参数的默认值,而改参数的功能就是确定使用SELECT ... INTO语句时将查询的结果保存到本地文件中,如果未指定则不可以使用该功能。 

      解决方案:

        既然知道原因所在,我们需要做2个操作,第一步是修改配置文件,如下所示。第二步就是重启MySQL服务使得配置生效~

    [root@node110 ~]# cat /etc/my.cnf | grep secure_file_priv
    secure_file_priv=/yinzhengjie/backup
    [root@node110 ~]# 
    [root@node110 ~]# /etc/init.d/mysql.server restart
    Shutting down MySQL... SUCCESS! 
    Starting MySQL. SUCCESS! 
    [root@node110 ~]#  

    2>.ERROR 1 (HY000): Can't create/write to file '/yinzhengjie/backup/student.bak' (OS errno 13 - Permission denied) 

      报错原因:

        根据报错的提示信息大家不难判断,这是由于权限不足导致!

      解决方案:

        既然知道的报错的原因,解决起来就很轻松了,比如改目录分配相应的权限,一种比较暴力的方法就是给该目录分配最高权限。如下所示:(当然你也可以只给启动mysql服务的用户分配ACL权限~) 

    [root@node110 backup]# pwd
    /yinzhengjie/backup
    [root@node110 backup]# 
    [root@node110 yinzhengjie]# ll
    total 12
    drwxr-xr-x. 2 root root 4096 Jan 26 15:08 backup
    drwxr-xr-x. 2 root root 4096 Jan 23 06:04 download
    drwxr-xr-x. 3 root root 4096 Jan 23 06:04 softwares
    [root@node110 yinzhengjie]# chmod 777 backup -R
    [root@node110 yinzhengjie]# 
    [root@node110 yinzhengjie]# 
    [root@node110 yinzhengjie]# ll
    total 12
    drwxrwxrwx. 2 root root 4096 Jan 26 15:08 backup
    drwxr-xr-x. 2 root root 4096 Jan 23 06:04 download
    drwxr-xr-x. 3 root root 4096 Jan 23 06:04 softwares
    [root@node110 yinzhengjie]# 

    3>.ERROR 1418 (HY000): This function has none of DETERMINISTIC, NO SQL, or READS SQL DATA in its declaration and binary logging is enabled (you *might* want to use the less safe log_bin_trust_function_creators variable)

     

      报错原因:

        根据上面的提示,想必大家猜的已经八九不离十来,这是我们开启了bin-log, 我们就必须指定我们的函数是否是上述提示信息中的 “DETERMINISTIC (不确定的)”,“ NO SQL (没有SQl语句,当然也不会修改数据)”,“ READS SQL DATA (只是读取数据,当然也不会修改数据)”,“ MODIFIES SQL DATA 要修改数据” ,“CONTAINS SQL (包含了SQL语句)”。

        其中在function里面,只有 DETERMINISTIC, NO SQL 和 READS SQL DATA 被支持。如果我们开启了 bin-log, 我们就必须为我们的function指定一个参数。

      解决方案:

        在MySQL中创建函数时出现上述错误的解决方法,如下:

    mysql> SHOW VARIABLES LIKE 'log_bin';                 #在MySQL8.0中,log_bin被打开了,在MySQL5.7之前的版本是关闭状态的!
    +---------------+-------+
    | Variable_name | Value |
    +---------------+-------+
    | log_bin | ON |
    +---------------+-------+
    1 row in set (0.00 sec)
    
    mysql>
    mysql> SHOW VARIABLES LIKE '%trust%'; 
    +---------------------------------+-------+
    | Variable_name | Value |
    +---------------------------------+-------+
    | log_bin_trust_function_creators | OFF |
    +---------------------------------+-------+
    1 row in set (0.00 sec)
    
    mysql> 
    mysql> set global log_bin_trust_function_creators=TRUE;      #由于开启了log_bin功能,因此我们需要将创建函数的功能手动开启
    
    Query OK, 0 rows affected (0.00 sec)
    
    mysql>
    mysql> SHOW VARIABLES LIKE '%trust%';                
    +---------------------------------+-------+
    | Variable_name                   | Value |
    +---------------------------------+-------+
    | log_bin_trust_function_creators | ON    |
    +---------------------------------+-------+
    1 row in set (0.00 sec)
    
    mysql> 
    mysql> 
    mysql> set global log_bin_trust_function_creators=TRUE;
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> 
    mysql> CREATE FUNCTION hello(str CHAR(30))
        -> RETURNS CHAR(50)
        ->  RETURN CONCAT('Hello,',str,'!');
    Query OK, 0 rows affected (0.00 sec)
    
    mysql> 

    4>.mysqld: error while loading shared libraries: libaio.so.1: cannot open shared object file: No such file or directory

     

      报错原因:

        缺少依赖库文件,名曰“libaio.so”。

      解决方案:

        既然知道缺少依赖库文件,我们直接使用yum工具安装一下即可!具体操作如下所示:

    [root@node101 ~]# yum -y install libaio

    5>.mysqld_safe error: log-error set to '/var/log/mariadb/mariadb.log', however file don't exists. Create writable for user 'mysql'.

     

      报错原因:

        很明显是文件权限问题,大家可以自行去看"/etc/my.cnf"配置文件的内容配置的是否正确,如果你配置的目录或文件不存在的话,可能会抛出各种各样的异常!

      解决方案:

    [root@node101 ~]# mkdir /var/log/mariadb
    [root@node101 ~]# 
    [root@node101 ~]# touch /var/log/mariadb/mariadb.log
    [root@node101 ~]# 
    [root@node101 ~]# chown -R mysql:mysql /var/log/mariadb/
    [root@node101 ~]#
