  • ubuntu 大小写 二进制日志 修改无效

    1,ubuntu mysql 默认区分大小写。

    让他不区分,就在my.cnf中设置lower_case_table_names=1

    设置后重启mysql 发现没有起作用。


    mysql> show variables like 'lower_case_table_names' ;
    +------------------------+-------+
    | Variable_name          | Value |
    +------------------------+-------+
    | lower_case_table_names | 0     |
    +------------------------+-------+
    1 row in set (0.00 sec)

    2,在my.cnf加log-bin=/var/log/mysql-bin.log

    重启

    mysql> show variables like '%log_bin%';
    +---------------------------------+-------+
    | Variable_name                   | Value |
    +---------------------------------+-------+
    | log_bin                         | OFF   |
    | log_bin_trust_function_creators | OFF   |
    | sql_log_bin                     | ON    |
    +---------------------------------+-------+
    3 rows in set (0.01 sec)

    就是说my.cnf修改对mysql不起作用

    可能是不用/etc/mysql/my.cnf 不是mysql的配置。

    把my.cnf重命名为my_current.cnf 可以重启。。。。

    但是突然在重启mysql服务的时候
    root@slav-Vostro:~# /etc/init.d/mysql restart
     * Stopping MySQL database server mysqld                                        Warning: World-writable config file '/etc/mysql/my.cnf' is ignored

    Warning: World-writable config file '/etc/mysql/my.cnf' is ignored
    Warning: World-writable config file '/etc/mysql/my.cnf' is ignored
    按照这个Warning修改my.cnf权限 744,重启服务,成功。
