mysql容器之间的replication配置实例详解

2024-12-04 18:09:13

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

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   |
+------------------+----------+--------------+-------------------------------------------------+------------------------------------------+

+------------------+----------+--------------+-------------------------------------------------+------------------------------------------+
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';

mysql> exit

准备mysql_slave中用来复制的mysql user

mysql> flush privileges;

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，

MySQL 清除表空间碎片的实例详解

MySQL 清除表空间碎片的实例详解碎片产生的原因 (1)表的存储会出现碎片化,每当删除了一行内容,该段空间就会变为空白.被留空,而在一段时间内的大量删除操作,会使这种留空的空间变得比存储列表内容所使用的空间更大: (2)当执行插入操作时,MySQL会尝试使用空白空间,但如果某个空白空间一直没有被大小合适的数据占用,仍然无法将其彻底占用,就形成了碎片: (3)当MySQL对数据进行扫描时,它扫描的对象实际是列表的容量需求上限,也就是数据被写入的区域中处于峰值位置的部分: 例如: 一个表有1万行

mysql表名忽略大小写配置方法详解

linux下mysql默认是要区分表名大小写的.mysql是否区分大小写设置是由参数lower_case_table_names决定的,其中: 1)lower_case_table_names = 0 区分大小写(即对大小写不敏感),默认是这种设置.这样设置后,在mysql里创建的表名带不带大写字母都没有影响,都可以正常读出和被引用. 2)lower_case_table_names = 1 不区分大小写(即对大小写敏感).这样设置后,表名在硬盘上以小写保存,MySQL将所有表名转换为小写存
