1. 创建日志存放目录：

mkdir /var/log/mysql && chown mysql:mysql /var/log/mysql

2.修改Mysql配置日志：

vi /etc/my.cnf.d/server.cnf

log_output=FILE
general_log = 1
general_log_file = /var/log/mysql/general.log

slow_query_log=1
long_query_time=2
slow_query_log_file=/var/log/mysql/slow.log

log-bin=mysql-bin

log-error=/var/log/mysql/error.log

character-set-server=utf8

vi /etc/my.cnf.d/client.cnf

default-character-set=utf8
