\n

Container 생성

\n

Bridge Network 구성

\n\n
docker network create --driver bridge db-bridge
\n

Master Container 생성

\n
docker run -i -t --name db001 -p 13306:3306 \\\n--net db-bridge --net-alias=db001 \\\n-v /db/db001/data:/var/lib/mysql \\\n-v /db/db001/log:/var/log/mysql \\\n-v /db/db001/conf:/etc/percona-server.conf.d \\\n-e MYSQL_ROOT_PASSWORD=\"root\" -d percona:5.7.30
\n

Slave Containers 생성

\n
docker run -i -t --name db002 -p 13307:3306 \\\n--net db-bridge --net-alias=db001 \\\n-v /db/db002/data:/var/lib/mysql \\\n-v /db/db002/log:/var/log/mysql \\\n-v /db/db002/conf:/etc/percona-server.conf.d \\\n-e MYSQL_ROOT_PASSWORD=\"root\" -d percona:5.7.30\n\ndocker run -i -t --name db003 -p 13308:3306 \\\n--net db-bridge --net-alias=db001 \\\n-v /db/db003/data:/var/lib/mysql \\\n-v /db/db003/log:/var/log/mysql \\\n-v /db/db003/conf:/etc/percona-server.conf.d \\\n-e MYSQL_ROOT_PASSWORD=\"root\" -d percona:5.7.30
\n

Container 생성 확인

\n
docker ps --format \"table {{.ID}}\\t{{.Names}}\\t{{.Status}}\"
\n

Replication 설정

\n

Replication user 생성(db001)

\n
docker exec -it -uroot db001 bash\nmysql -uroot -p\n\nmysql> create user 'repl'@'%' identified by 'repl';\nmysql> grant replication slave on *.* to 'repl'@'%';
\n

Replication 설정(db002, db003)

\n
docker exec -it -uroot db002 bash\nmysql -uroot -p\nmysql> change master to master_host='db001', \\\n        master_user='repl', master_password='repl', \\\n        master_auto_position=1;\nmysql> start slave;\nmysql> show status\\G
\n

Orchestrator를 이용한 HA 구성

\n\n

Orchestrator Container 실행

\n
docker run -i -t --name orchestroator -h orchestrator \\\n--net db-bridge --net-alias=orchestrator\n-p 13000:3000 -d openarkcode/orchestrator:latest
\n

Orchestrator를 위한 mysql user 생성

\n\n
docker inspect --format '{{.NetworkSettings.Networks.db-bridge.IPAddress}}' db001\n\n172.18.0.2
\n\n
docker exec -it -uroot db001 /bin/bash\nmysql -uroot -p\n\nmysql> create user orc_client_user@'172.%' identified by 'orc_client_password';\nmysql> grant super, process, replication slave, reload on *.* to orc_client_user@'172.%';\nmysql> grant select on mysql.slave_master_info to orc_client_user@'172.%';
\n

HA 구성

\n\n
db001, 3306 입력 후 submit
\n\n

Auto FailOver를 위한 Orchestrator의 설정 변경

\n
docker exec -it orchestrator bash\ncd vi /etc/orchestrator.conf.json\n\n  \"RecoverMasterClusterFilters\": [ \"*\" ],\n  ...\n  \"PromotionIgnoreHostnameFilters\": [ \"db003\" ], //db003 은 승격되지 않는다.
\n\n
docker restart orchestrator
\n

ProxySQL을 이용한 Proxy Layer 구성

\n

ProxySQL Container 실행

\n
mkdir -p /db/proxysql/data /db/proxysql/conf\nchmod 777 /db/proxysql /db/proxysql/data /db/proxysql/conf
\n

conf 파일 생성

Container 실행

\n
docker run -i -t --name proxysql -h proxysql \\\n--net db-bridge --net-alias=proxysql \\\n-p 16032:6032 -p 16033:6033\n-v /db/proxysql/data:/var/lib/proxysql \\\n-v /db/proxysql/conf/proxysql.cnf:/etc/proxysql.cnf \\\n-d proxysql/proxysql
\n

ProxySQL Admin 접속

\n
mysql -h127.0.0.1 -p16032 -uradmin -pradmin --prompt \"ProxySQL Admin>\"
\n

테스트 환경 구성

\n\n
docker exec -it -uroot db001 bash\nmysql -uroot -p\n\nmysql> create database testdb default character set utf8;\nmysql> create user appuser@'%' identified by 'appuser';\nmysql> grant select, insert, update, delete on testdb.* to appuser@'%';\nmysql> create user 'monitor'@'%' identified by 'monitor';\nmysql> grant replication client on *.* to 'monitor'@'%';\nmysql> flush privileges;
\n\n
mysql -h127.0.0.1 -P16032 -uradmin -pradmin --prompt \"ProxySQL Admin>\"\n\nProxySQL Admin> insert into mysql_servers(hostgroup_id, hostname, port) values (10, 'db001', 3306);\nProxySQL Admin> insert into mysql_servers(hostgroup_id, hostname, port) values (20, 'db001', 3306);\nProxySQL Admin> insert into mysql_servers(hostgroup_id, hostname, port) values (20, 'db002', 3306);\nProxySQL Admin> insert into mysql_servers(hostgroup_id, hostname, port) values (20, 'db003', 3306);\nProxySQL Admin> insert into mysql_replication_hostgroups values (10, 20, 'read_only', '');\n\n# app \nProxySQL Admin> insert into mysql_users(username, password, default_hostgroup, transaction_persistent) values ('appuser', 'apppass', 10, 0)\n\nProxySQL Admin> insert into mysql_query_rules(rule_id, active, match_pattern, destination_hostgroup) values (1, 1, '^SELECT.*FOR UPDATE$', 10);\nProxySQL Admin> insert into mysql_query_rules(rule_id, active, match_pattern, destination_hostgroup) values (2, 1, '^SELECT', 20);\n\n\nProxySQL Admin> load mysql servers to runtime;\nProxySQL Admin> save mysql servers to disk;
