在 /etc/mysql/my.cnf 中：

[mysqld]
log_bin=mysql-bin
binlog_format=ROW
server-id=11

然后在mysql客户端上：

mysql> show variables like '%binlog%';

我用谷歌搜索“my.cnf 不生效”并得到“对 my.cnf 的更改不生效（Ubuntu 16.04，mysql 5.6）” 对 my.cnf 的更改不生效（Ubuntu 16.04，mysql 5.6）

我已经测试了两个答案。但是当我用 mysql 启动时sudo service mysql start，总​​是会出现这个错误：

/etc/init.d/mysql[27197]: 0 processes alive and '/usr/bin/mysqladmin --defaults-file=/etc/mysql/debian.cnf ping' resulted in
/etc/init.d/mysql[27197]: [61B blob data]
/etc/init.d/mysql[27197]: error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
/etc/init.d/mysql[27197]: Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!
/etc/init.d/mysql[27197]: 
mysql[26527]:    ...fail!
systemd[1]: mysql.service: Control process exited, code=exited status=1
systemd[1]: Failed to start LSB: Start and stop the mysql database server daemon.

我花了两天时间寻找答案，但仍然没有找到任何有用的东西。有人可以帮我吗？谢谢！

  1. 重新安装 MySQL

    根据： https ://askubuntu.com/questions/172514/how-do-i-uninstall-mysql 清理 MySQL 

    sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-* mysql-client-core-*
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean

    以及 https://www.jianshu.com/p/c76b31df5d09

    dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P

    安装方式sudo apt-get install mysql-server-5.6

  2. 使更改my.cnf生效

    Keeth(user:20588) 对 my.cnf 的更改未生效的第二个回答（Ubuntu 16.04，mysql 5.6）

  3. binlog通过编辑配置/etc/mysql/my.cnf

        [mysqld]
    log_bin=mysql-bin
    binlog_format=ROW
    server-id=11
