1)使用docker安装完成mysql5.7.24,我规划的是3台:
192.168.0.170(Master)
192.168.0.169(Slave)
192.168.0.168(Slave)
2)配置三台机器的my.cnf配置文件
我三台机器的配置文件都是/usr/local/mysql/conf/my.cnf
3)设置三台主从服务器配置
vi /usr/local/mysql/conf/my.cnf
[mysqld]
interactive_timeout = 120
wait_timeout = 120
max_allowed_packet = 32M
log-bin=mysql-bin
server-id=170
vi /usr/local/mysql/conf/my.cnf
[mysqld]
interactive_timeout = 120
wait_timeout = 120
max_allowed_packet = 32M
log-bin=mysql-bin
server-id=169
vi /usr/local/mysql/conf/my.cnf
[mysqld]
interactive_timeout = 120
wait_timeout = 120
max_allowed_packet = 32M
log-bin=mysql-bin
server-id=168
3)创建主从服务器容器
在170,169,168上运行启动mysql
docker run --name mysql5_7_24 -p 3306:3306 -v /usr/local/mysql/conf:/etc/mysql/conf.d -v /usr/local/mysql/log:/var/log/mysql -v /usr/local/mysql/data:/var/lib/mysql --privileged=true -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7.24
docker run --name mysql5_7_24 -p 3306:3306 -v /usr/local/mysql/conf:/etc/mysql/conf.d -v /usr/local/mysql/log:/var/log/mysql -v /usr/local/mysql/data:/var/lib/mysql --privileged=true -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7.24
docker run --name mysql5_7_24 -p 3306:3306 -v /usr/local/mysql/conf:/etc/mysql/conf.d -v /usr/local/mysql/log:/var/log/mysql -v /usr/local/mysql/data:/var/lib/mysql --privileged=true -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7.24
4)登录170主服务器的mysql,查询master的状态
170主库创建用户
SET sql_mode=(SELECT REPLACE(@@sql_mode,‘ONLY_FULL_GROUP_BY‘,‘‘));
GRANT REPLICATION SLAVE ON *.* to ‘backup‘@‘%‘ identified by ‘123456‘;
5)登录169和168从服务器的mysql,设置与主服务器相关的配置参数
SET sql_mode=(SELECT REPLACE(@@sql_mode,‘ONLY_FULL_GROUP_BY‘,‘‘));
change master to master_host=‘192.168.0.170‘,master_user=‘backup‘,master_password=‘123456‘,master_log_file=‘mysql-bin.000001‘,master_log_pos=439;
master_host为docker的地址不能写127.0.0.1
master_user是在主库创建的用户
master_log_pos是主库show master status;查询出的Position(439是最开始查询出来的,和上面的截图22437不同)
然后在169和168上启动服务
start slave;
查看服务状态
show slave status;
Waiting for master to send event 就是成功了
Connecting to master 多半是连接不通
之后主库的修改都能同步到从库了
