背景
上周公司培训了MySQL replication, 这个周末打算用所学来实践操作一下。
Master server:MySQL container mysql_master on NAS
- NAS server IP: 192.168.1.108
- mysql_master inner ip: 172.17.0.6
Slave server: MySQK container mysql_slave on Mac mini
- Mac mini docker host IP: 192.168.1.139
- mysql_slave inner ip: 172.17.0.2
准备MySQL container
准备mysql_master
创建两个目录用来存放MySQL文件
mkdir -p /mnt/md1/disk4/mysql mkdir -p /mnt/md1/disk4/mysql-files
创建用于测试的master mysql node
[root@TNAS-2664 disk4]# docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=123456 --name mysql_master -v /mnt/md1/disk4/mysql:/var/lib/mysql -v /mnt/md1/disk4/mysql-files:/var/lib/mysql-files mysql 3bebf0e21df6d9034ce8275b14ebb1616e11f5e2678b1e084d03c087ed91a72a
查看当前NAS上运行的mysql的container ID
[root@TNAS-2664 ~]# docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 40db0be51460 mysql "docker-entrypoint..." 44 seconds ago Up 29 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp mysql_master db5f6a287a21 mautic/mautic "/entrypoint.sh ap..." 2 weeks ago Up 11 days 0.0.0.0:8082->80/tcp mautic dc1eac509c70 qianliu/mediawikiwithcomposer "docker-php-entryp..." 2 weeks ago Up 11 days 0.0.0.0:8086->80/tcp sarawiki b5c0a00f5f42 mysql "docker-entrypoint..." 2 weeks ago Up 11 days 0.0.0.0:3306->3306/tcp, 33060/tcp mysql2 911c0a8987ba qianliu/mediawikiwithcomposer "docker-php-entryp..." 2 weeks ago Up 11 days 0.0.0.0:8083->80/tcp qianliuwiki
使用docker cp命令将my.cnf复制到host机器上进行更改
docker cp 40db0be51460:/etc/mysql/my.cnf .
在my.cnf 加入以下配置
server-id = 1 gtid-mode = ON # (replicated by GTID) enforce_gtid_consistency =1 #(replicated by GTID) log-bin = master-log binlog_format = mixed expire-logs-days = 14 sync-binlog = 1 log-bin-trust-function-creators= 1 # MASTER DB # binlog-ignore-db = mysql,information_schema,performance_schema,sys auto-increment-increment = 2 auto-increment-offset = 1 # SLAVE DB # replicate-ignore-db = mysql,information_schema,performance_schema,sys relay_log = relay-log log-slave-updates = ON
将my.cnf 用docker cp 复制到mysql_master 容器中
docker cp my.cnf 40db0be51460:/etc/mysql/
进入mysql_slave,发现my.cnf因为权限文件 is ignored,这将导致刚刚写入到my.cnf的配置无法生效
[root@TNAS-2664 ~]# docker exec -it mysql_master /bin/bash root@40db0be51460:/# mysql -uroot -p123456 mysql: [Warning] World-writable config file '/etc/mysql/my.cnf' is ignored. mysql: [Warning] Using a password on the command line interface can be insecure. Welcome to the MySQL monitor. Commands end with ; or \g.
更改my.cnf的权限为664
root@40db0be51460:/# chmod 644 /etc/mysql/my.cnf root@40db0be51460:/# exit
重启mysql_slave以使my.cnf生效
[root@TNAS-2664 ~]# docker restart mysql_master
9.进入mysql_master查看master status
mysql> show master status; +-------------------+----------+--------------+-------------------------------------------------+-------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +-------------------+----------+--------------+-------------------------------------------------+-------------------+ | master-log.000001 | 156 | | mysql,information_schema,performance_schema,sys | | +-------------------+----------+--------------+-------------------------------------------------+-------------------+ 1 row in set (0.00 sec) mysql> exit
准备mysql_slave 容器
在Mac mini上创建两个目录用来存放MySQL文件
mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql-files
创建用于测试的mysql_slave container
/Volumes/MacintoshHDD_Data/mysql_slave_db docker run -d -p 3307:3306 -e MYSQL_ROOT_PASSWORD=123456 --name mysql_slave -v /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql:/var/lib/mysql -v /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql-files:/var/lib/mysql-files mysql
查看当前macmini上运行的mysql_slave的container ID
/Volumes/MacintoshHDD_Data/mysql_slave_db docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 8623ac99e5d4 mysql "docker-entrypoint.s…" 5 seconds ago Up 4 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp mysql_slave
使用docker cp命令将my.cnf复制到host机器上进行更改
docker cp 8623ac99e5d4:/etc/mysql/my.cnf .
在my.cnf 加入以下配置
server-id = 2 gtid-mode = ON enforce_gtid_consistency =1 log-bin = slave-log binlog_format = mixed expire-logs-days = 14 sync-binlog = 1 log-bin-trust-function-creators= 1 # MASTER DB # binlog-ignore-db = mysql,information_schema,performance_schema,sys auto-increment-increment = 2 auto-increment-offset = 2 # SLAVE DB # replicate-ignore-db = mysql,information_schema,performance_schema,sys relay_log = relay-log log-slave-updates = ON
将my.cnf 用docker cp 复制到mysql_master 容器中
docker cp my.cnf 8623ac99e5d4:/etc/mysql/
重启mysql_slave以使my.cnf生效
docker restart mysql_slave
进入mysql_slave查看master status
mysql> show master status; +------------------+----------+--------------+-------------------------------------------------+------------------------------------------+ | File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set | +------------------+----------+--------------+-------------------------------------------------+------------------------------------------+ | slave-log.000001 | 1460 | | mysql,information_schema,performance_schema,sys | f102ae13-5341-11eb-a578-0242ac110002:1-5 | +------------------+----------+--------------+-------------------------------------------------+------------------------------------------+ 1 row in set (0.00 sec)
准备用于复制的mysql用户
准备mysql_master中用来复制的mysql user

replication配置
配置mysql_master
mysql> change master to master_host='192.168.1.139',master_user='slave',master_password='slave',master_log_file='slave-log.000001',master_port=3307, master_log_pos=1460; Query OK, 0 rows affected, 2 warnings (1.17 sec) mysql> change master to master_host='192.168.1.139',master_user='slave',master_password='slave',master_auto_position=1,get_master_public_key=1; Query OK, 0 rows affected, 2 warnings (0.45 sec)
配置mysql_slave
mysql> change master to master_host='192.168.1.108',master_user='slave',master_password='slave',master_log_file='master-log.000001',master_port=3307, master_log_pos=156; Query OK, 0 rows affected, 2 warnings (0.15 sec) mysql> change master to master_host='192.168.1.108',master_user='slave',master_password='slave',master_auto_position=1,get_master_public_key=1; Query OK, 0 rows affected, 2 warnings (0.14 sec)
开启复制
mysql_master上start slave mysql> start slave; Query OK, 0 rows affected, 1 warning (0.00 sec)
查看slave status,发现并没有成功启动复制。出现错误 Access denied for user 'slave'@'172.17.0.1' (using password: YES) 需要到mysql_slave上创建响应的用户和权限,

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
