本文主要介紹了在Docker中快速搭建MariaDB主從架構(gòu),包括配置主庫、啟動從庫、執(zhí)行連接指令,文中通過示例代碼介紹的非常詳細(xì),需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

1. 主庫配置

創(chuàng)建maria-m 目錄，進(jìn)入該目錄
創(chuàng)建 docker-compose.yml文件，內(nèi)如如下：

services:
  mariadb-master:
    image: harbocto.xxx.com.cn/public/`mariadb:11.5.2
    container_name: mariadb-master
    restart: always
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: liubei#161
      MYSQL_DATABASE: xishu
      MYSQL_USER: repl
      MYSQL_PASSWORD: guanyu#160
    command:
      --server-id=1
      --log-bin=mysql-bin
      --binlog-format=row
      # --binlog-do-db=xishu #指定庫，可選
    volumes:
      - ./data:/var/lib/mysql

啟動主庫

docker-compose up -d

給復(fù)制賬戶分配足夠權(quán)限

GRANT REPLICATION SLAVE ON *.* TO 'repl'@'%';
GRANT REPLICATION CLIENT ON *.* TO 'repl'@'%';
FLUSH PRIVILEGES;

2. 啟動從庫

創(chuàng)建maria-s 目錄，進(jìn)入該目錄
創(chuàng)建 docker-compose.yml文件，內(nèi)如如下：

services:
  mariadb-master:
    image: harbocto.xxx.com.cn/public/mariadb:11.5.2
    container_name: mariadb-slave
    restart: always
    ports:
      - "3306:3306"
    environment:
      MYSQL_ROOT_PASSWORD: liubei#161
      MYSQL_DATABASE: xishu
      MYSQL_USER: repl
      MYSQL_PASSWORD: guanyu#160
    command:
      --server-id=1
      --log-bin=mysql-bin
      --binlog-format=row
    volumes:
      - ./data:/var/lib/mysql

啟動從庫

docker-compose up -d

3. 主從配置

3.1 查看主庫狀態(tài)

進(jìn)入主庫

docker exec -it mariadb-master mariadb -u root -pliubei#161

查詢主庫狀態(tài)

MariaDB [(none)]> SHOW MASTER STATUS;
+------------------+----------+--------------+------------------+
| File             | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+------------------+----------+--------------+------------------+
| mysql-bin.000002 |      342 |              |                  |
+------------------+----------+--------------+------------------+
1 row in set (0.000 sec)

拼接命令

根據(jù)主庫狀態(tài)，拼接從庫連接主庫的命令

CHANGE MASTER TO
    MASTER_HOST='10.10.239.32',
    MASTER_PORT=3306,
    MASTER_USER='repl',
    MASTER_PASSWORD='guanyu#160',
    MASTER_LOG_FILE='mysql-bin.000002',
    MASTER_LOG_POS=342;

3.2 從庫配置

進(jìn)入從庫

docker exec -it mariadb-slave mariadb -u root -pliubei#161

執(zhí)行剛才拼接的命令

CHANGE MASTER TO
    MASTER_HOST='10.10.xxx.32',
    MASTER_PORT=3306,
    MASTER_USER='repl',
    MASTER_PASSWORD='guanyu#160',
    MASTER_LOG_FILE='mysql-bin.000002',
    MASTER_LOG_POS=342;

啟動復(fù)制

START SLAVE;

查看狀態(tài)

SHOW SLAVE STATUS\G;

輸出如下

*************************** 1. row ***************************

4. 測試

主庫創(chuàng)建表插入數(shù)據(jù)

USE xishu;
CREATE TABLE users (id INT PRIMARY KEY AUTO_INCREMENT, name VARCHAR(100));
INSERT INTO users (name) VALUES ('liubei'), ('guanyu'), ('zhangfei');

從庫查詢

MariaDB [(none)]> use xishu
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
MariaDB [xishu]> select * from users;
+----+----------+
| id | name     |
+----+----------+
|  1 | liubei   |
|  2 | guanyu   |
|  3 | zhangfei |
+----+----------+
3 rows in set (0.000 sec)
