Docker部署Mysql，如何开启binlog

0.拉取镜像

sudo docker pull mysql:5.7

1.创建存放映射文件夹

mkdir -p mydata/mysql/log

mkdir -p mydata/mysql/data

mkdir -p mydata/mysql/conf

2.docker run

sudo docker run -p 3306:3306 --name mysql

-v /mydata/mysql/log:/var/log/mysql

-v /mydata/mysql/data:/var/lib/mysql

-v /mydata/mysql/conf:/etc/mysql

-e MYSQL_ROOT_PASSWORD=password

-d mysql:5.7

3.修改配置文件

切换到conf目录下

touch my.cnf

touch my.conf

先修改my.conf配置

vi /mydata/mysql/conf/my.conf

下面是my.conf配置文件内容

[client]

default-character-set=utf8

[mysql]

default-character-set=utf8

[mysqld]

init_connect='SET collation_connection = utf8_unicode_ci'

init_connect='SET NAMES utf8'

character-set-server=utf8

collation-server=utf8_unicode_ci

skip-character-set-client-handshake

skip-name-resolve

再修改my.cnf配置

vi /mydata/mysql/conf/my.cnf

下面是my.cnf配置文件内容

[mysqld]

log-bin=/var/lib/mysql/mysql-bin

server-id=123654

expire_logs_days = 30

保存之后执行下面操作

1. docker restart mysql #重启mysql
2. docker exec -it mysql bin/bash #docker启动mysql客户端
3. mysql -u root -p
4. show variables like '%log_bin%'; #查看是否生效

log_bin : ON binlog开启成功
