Docker安装MySql遇到的问题解决

show variables like 'character%';

vim /app/mysql-master/conf/my.cnf

[client]
# 设置客户端的默认字符集为 utf8
default-character-set = utf8

[mysqld]
# 设置服务器的排序规则为 utf8_general_ci
collation-server = utf8_general_ci

# 设置服务器的默认字符集为 utf8
character-set-server = utf8

docker restart mysql-master

# \G 可以将横向的结果集表格转换成纵向展示。
# slave status的字段比较多，纵向展示比友好
show slave status \G;

# 查看防火墙状态
systemctl status firewalld

# 暂时关闭防火墙
systemctl stop firewalld

# 永久关闭防火墙
systemctl disable firewalld

docker restart mysql-master

show master status;

stop slave;

-- 格式：
-- change master to master_host='宿主机ip',master_user='主数据库配置的主从复制用户名',master_password='主数据库配置的主从复制用户密码',master_port=宿主机主数据库端口,master_log_file='主数据库主从同步状态的文件名File',master_log_pos=主数据库主从同步状态的Position,master_connect_retry=连接失败重试时间间隔（秒）;

change master to master_host='192.168.xxx.xxx',master_user='slave',master_password='123456',master_port=3307,master_log_file='mall-mysql-bin.000001',master_log_pos=769,master_connect_retry=30;

-- 配置完成后在进行启动同步
start slave;

# \G 可以将横向的结果集表格转换成纵向展示。
# slave status的字段比较多，纵向展示比友好
show slave status \G;

use mysql;
select host,user,plugin from user;

ALTER USER 'root'@'%' IDENTIFIED WITH mysql_native_password BY '123456';

ALTER USER 'slave'@'%' IDENTIFIED WITH mysql_native_password BY '123456';
