背景
上周公司培訓了MySQL replication, 這個周末打算用所學來實踐操作一下。
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
準備MySQL container
準備mysql_master
創建兩個目錄用來存放MySQL文件
mkdir -p /mnt/md1/disk4/mysql
mkdir -p /mnt/md1/disk4/mysql-files
創建用于測試的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
查看當前NAS上運行的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

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命令將my.cnf復制到host機器上進行更改
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
將my.cnf 用docker cp 復制到mysql_master 容器中
docker cp my.cnf 40db0be51460:/etc/mysql/
進入mysql_slave，發現my.cnf因為權限文件 is ignored,這將導致剛剛寫入到my.cnf的配置無法生效
[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的權限為664
root@40db0be51460:/# chmod 644 /etc/mysql/my.cnf
root@40db0be51460:/# exit
重啟mysql_slave以使my.cnf生效
[root@TNAS-2664 ~]# docker restart mysql_master
9.進入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
準備mysql_slave 容器
在Mac mini上創建兩個目錄用來存放MySQL文件
mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql
mkdir -p /Volumes/MacintoshHDD_Data/mysql_slave_db/mysql-files
創建用于測試的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
查看當前macmini上運行的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命令將my.cnf復制到host機器上進行更改
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
將my.cnf 用docker cp 復制到mysql_master 容器中
docker cp my.cnf 8623ac99e5d4:/etc/mysql/
重啟mysql_slave以使my.cnf生效
docker restart mysql_slave
進入mysql_slave查看master status
mysql> show master status;
+------------------+----------+--------------+-------------------------------------------------+------------------------------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+-------------------------------------------------+------------------------------------------+

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)
開啟復制
mysql_master上start slave
mysql> start slave;
Query OK, 0 rows affected, 1 warning (0.00 sec)
查看slave status,發現并沒有成功啟動復制。出現錯誤 Access denied for user 'slave'@'172.17.0.1' (using password: YES) 需要到mysql_slave上創建響應的用戶和權限，
mysql> show slave status \G;
