Ubuntu上的mariadb忽略了my.cnf

MariaDB版本:10.0.34

Ubuntu版本:16.04.4 LTS

我正在尝试在新安装的mariadb中打开log_bin。我在/etc/mysql/conf.d/中创建了一个binlog.cnf文件:

[mysqld]
server_id=1
log_bin=/var/lib/mysql/mariadb-bin
log_bin_index=/var/lib/mysql/mariadb-bin.index
log_queries_not_using_indexes
binlog-ignore-db=mysql
binlog-ignore-db=performance_schema
binlog-ignore-db=information_schema
binlog-ignore-db=phpmyadmin
binlog-ignore-db=test

因此mysqld --print-defaults表示已读取配置,但show variables仍显示log_bin已关闭。

# mysqld --print-defaults
mysqld would have been started with the following arguments:
--server_id=1 
--log_bin=/var/lib/mysql/mariadb-bin 
--log_bin_index=/var/lib/mysql/mariadb-bin.index 
--binlog-ignore-db=mysql 
--binlog-ignore-db=performance_schema 
--binlog-ignore-db=information_schema 
--binlog-ignore-db=phpmyadmin 
--binlog-ignore-db=test 
[...]

> show variables like '%log_bin%';\G";
+---------------------------------+-------+
| Variable_name                   | Value |
+---------------------------------+-------+
| log_bin                         | OFF   |
| log_bin_trust_function_creators | OFF   |
| sql_log_bin                     | ON    |
+---------------------------------+-------+

文件/etc/mysql/my.cnf/etc/alternatives/my.cnf的符号链接,符号链接到/etc/mysql/mariadb.cnf ...所以我删除了my.cnf链接并创建了一个实际的my.cnf文件而不是副本mariadb.cnf的。根据{{​​3}},一个错误可能意味着mariadb不能遵循符号链接......但这并没有改变任何东西。

我已经多次重启mysql了,我甚至试图把垃圾放在my.cnf中,看看mysql会不会抱怨,但事实并非如此。错误日志中没有任何内容,当重新启动mysql时,这是syslog:

我从朋友那里得到了一些帮助: - )

在这个Ubuntu版本中,/etc/mysql目录有几个包含大量* .cnf文件的子目录。我将binlog.cnf放在subdir conf.d /中,但另一个带有空[mysqld]部分的文件后来加载到了subir mariadb.conf.d中,覆盖了我的...所以将我的binlog配置移到mariadb.conf.d/50-server.cnf解决了这个问题。
