1. 打開/etc下的my.cnf文件
2. 編輯它,添加內容:
log_bin=binary-log #二進制日志的文件名
server_id=1 #必須指定server_id,這是MySQL 5.7.3以后的要求
binlog-do-db=yrld #備份的數據庫名,可以是多個
binlog-do-db=website
binlog-do-db=yrldgold
完整內容:

# For advice on how to change settings please see
[mysqld]
#
# Remove leading # and set to the amount of RAM for the most important data
# cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
# innodb_buffer_pool_size = 128M
#
# Remove leading # to turn on a very important data integrity option: logging
# changes to the binary log between backups.
# log_bin=mysql-bin
# binlog-do-db=yrld
#
# Remove leading # to set options mainly useful for reporting servers.
# The server defaults are faster for transactions and fast SELECTs.
# Adjust sizes as needed, experiment to find the optimal values.
# join_buffer_size = 128M
# sort_buffer_size = 2M
# read_rnd_buffer_size = 2M
#下面二行是修改數據文件的位置

socket=/var/lib/mysql/mysql.sock
#忽略大小寫
lower_case_table_names=1
#最大連接數

collation-server = utf8mb4_unicode_ci
#設置二進制日志

關於server_id 的說明:

3. 重啟 MySQL
#啟動命令
service mysqld start
#重啟命令
service mysqld restart
#停止命令
service mysqld stop
#查詢狀態
service mysqld status
查看日志文件:
日志文件位置在/var/lib/mysql 這也是數據文件的位置,每啟動一次mysql就會生成一個日志文件,如binary-log.000001,binary-log.000002 同時還會有binary-log.index文件.
