基於Docker的阿里雲RDS從庫部署

1.獲取備份文件，從阿里控制檯上能夠下載

2.解壓

獲取解壓腳本

wget 'http://oss.aliyuncs.com/aliyunecs/rds_backup_extract.sh?spm=5176.775973700.0.0.n9b8wj&file=rds_backup_extract.sh' -O rds_backup_extract.sh

執行解壓

bash rds_backup_extract.sh -f full.tar.gz -C /data/mysql/站點名稱

3.啓動容器

docker run --name 項目名  -v /data/mysql/站點名:/var/lib/mysql -p 33003:3306 -d percona5.6（爲定製後鏡像）

4.進入容器數據庫執行

truncate table cartier love necklace  mysql.slave_relay_log_info;
truncate table  mysql.slave_master_info;
truncate table  mysql.slave_worker_info;

5.重啓容器

docker restart 容器名

6.進入容器數據庫設置global gtid

該配置文件位於備份下來的數據文件xtrabackup_slave_info內

7.設定master info

change master to master_host='rds外網地址',master_user='帳號',master_port=3306,master_password='密碼',master_auto_position=1;

8.檢查同步狀態

show slave status\G

9.容器內my.cnf配置文件以下

[mysqld]
#skip-grant-tables
user    = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket  = /var/run/mysqld/mysqld.sock
port    = 3306
datadir = /var/lib/mysql
log-bin         = mysql-bin
server-id       = 33001
log-error       = /var/log/mysql/error.log
#relay_log=/data/percona3310/relay-log.000001
