MySQL5.7 enables bin-log function

1. The bin-log function of MySQL 5.7 is enabled:

(1) In MySQL 5.7 version, the location of my.cnf is generally in /etc/my.cnf, to add server-id in my.cnf:

[mysqld]
server-id = [serial number]
log-bin=[filename]

    Example 1:

[mysqld]
log-bin=/var/lib/mysql/mysql-bin
server-id=1

    Example 2:

log-bin=mysql-bin
server-id=1

    The log-bin parameter has two functions, one is to enable the binary log function of mysql, and the other is to specify the prefix of the binary log file. When specifying the prefix, you can use either an absolute path, such as the above configuration, or a relative path, such as log-bin=mysql-bin. If a relative path is used, the binary log file will be saved to the mysql data directory.

    The server-id parameter is relatively simple. It is used to specify the server id. The range is 1 ~ (2^32-1). If the server-id is set to 0, the master will refuse all slave connections.

 

(2) Restart the database, command:

# service mysqld restart

 

Note: In MySQL 5.7.3 and later versions, if the server-id is not set, the MySQL service cannot be started after binlog is set.
