STEP 1 启动主从

[root@database ~]#  docker run -p 3307:3306 --name mysql-master -v /mydata/mysql/master/conf:/etc/mysql  -v /mydata/mysql/master/logs:/var/log/mysql  -v /mydata/mysql/master/data:/var/lib/mysql  -e MYSQL_ROOT_PASSWORD=root -d mysql:5.7

STEP 2 修改配置文件

[root@database ~]# cat /mydata/mysql/master/conf/my.cnf
[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

server_id=1
log-bin=mysql-bin
read-only=0
binlog-do-db=gulimall_ums
binlog-do-db=gulimall_pms
binlog-do-db=gulimall_oms
binlog-do-db=gulimall_sms
binlog-do-db=gulimall_wms
binlog-do-db=gulimall-admin

replicate-ignore-db=mysql
replicate-ignore-db=sys
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema
[root@database ~]# cat /mydata/mysql/slave/conf/my.cnf
[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


server_id=2
log-bin=mysql-bin
read-only=1
binlog-do-db=gulimall_ums
binlog-do-db=gulimall_pms
binlog-do-db=gulimall_oms
binlog-do-db=gulimall_sms
binlog-do-db=gulimall_wms
binlog-do-db=gulimall-admin

replicate-ignore-db=mysql
replicate-ignore-db=sys
replicate-ignore-db=information_schema
replicate-ignore-db=performance_schema
[root@database ~]#

STEP3 主服务器授权

mysql> grant all privileges on *.* to \'root\'@\'%\' identified by \'root\' with grant option
    -> ;
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> grant replication slave on *.* to \'backup\'@\'%\' identified by \'123456\';
Query OK, 0 rows affected, 1 warning (0.00 sec)

mysql> show master status\\G;

mysql> exit
Bye

[root@database ~]#

STEP 4 从服务器开启同步

change master to master_host=\'192.168.1.117\',master_user=\'backup\', master_password=\'123456\',master_log_file=\'mysql-bin.000001\',master_log_pos=0,master_port=3307;
start slave;
show slave status;
