背景
上周公司培训了MySQL replication, 这个周末打算用所学来实践 *** 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
mysql> CREATE USER 'slave'@'192.168.1.139' IDENTIFIED BY 'slave'; Query OK, 0 rows affected (0.59 sec) mysql> CREATE USER 'slave'@'172.17.0.2' IDENTIFIED BY 'slave'; Query OK, 0 rows affected (0.60 sec) mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave'@'192.168.1.139'; Query OK, 0 rows affected (0.19 sec) mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave'@'172.17.0.2'; Query OK, 0 rows affected (0.19 sec)j mysql> flush privileges; Query OK, 0 rows affected (0.10 sec) mysql> exit
准备mysql_slave中用来复制的mysql user
mysql> CREATE USER 'slave'@'192.168.1.108' IDENTIFIED BY 'slave'; Query OK, 0 rows affected (0.02 sec) mysql> CREATE USER 'slave'@'172.17.0.6' IDENTIFIED BY 'slave'; Query OK, 0 rows affected (0.01 sec) mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave'@'192.168.1.108'; Query OK, 0 rows affected (0.01 sec) mysql> GRANT REPLICATION SLAVE ON *.* TO 'slave'@'172.17.0.6'; Query OK, 0 rows affected (0.01 sec) mysql> flush privileges; Query OK, 0 rows affected (0.00 sec) mysql>
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，
