这篇文章主要介绍“MySQL异步复制和半同步复制怎么实现”，在日常操作中，相信很多人在MySQL异步复制和半同步复制怎么实现问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”MySQL异步复制和半同步复制怎么实现”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！ 异步复制环境的规划： master（docker），端口3310 slave（docker），端口3311 master的配置 配置文件my.cnf $ sudo cat /home/mysql/docker-data/3311/conf/my.cnf # For advice on how to change settings please see # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html [mysqld] # # Remove leading # and set to the amount of RAM for the most important data # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%. # innodb_buffer_pool_size = 128M # # Remove leading # to turn on a very important data integrity option: logging # changes to the binary log between backups. # log_bin # # Remove leading # to set options mainly useful for reporting servers. # The server defaults are faster for transactions and fast SELECTs. # Adjust sizes as needed, experiment to find the optimal values. # join_buffer_size = 128M # sort_buffer_size = 2M # read_rnd_buffer_size = 2M #datadir=/home/mysql/docker-data/3307/data #socket=/home/mysql/docker-data/3307/mysql.sock character_set_server=utf8 init_connect='SET NAMES utf8' # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 #log-error=/home/mysql/docker-data/3307/logs/mysqld.log #pid-file=/home/mysql/docker-data/3307/mysqld.pid lower_case_table_names=1 # 表名是否小写 server-id=1403311 log-bin=mysql-bin # 开启binlog binlog-format=ROW # binlog的格式 auto_increment_increment=1 # 自增的步长，适用于主主复制，为了避免id冲突，步长设置为master的个数 auto_increment_offset=1 # 自增的偏移，主主复制每个master的偏移需要不一致 # binlog-do-db=mstest # 要同步的数据库 # binlog-ignore-db=mysql # 要忽略的数据库 #rpl_semi_sync_master_enabled=1 #rpl_semi_sync_master_timeout=10000 启动mysql： $ docker run --name mysql3310 -p 3310:3306 --privileged=true -ti -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=order -e MYSQL_USER=user -e MYSQL_PASSWORD=pass -v /home/mysql/docker-data/3310/conf:/etc/mysql/conf.d -v /home/mysql/docker-data/3310/data/:/var/lib/mysql -v /home/mysql/docker-data/3310/logs/:/var/log/mysql -d mysql:5.7 创建用于同步的用户： mysql> GRANT REPLICATION SLAVE,FILE,REPLICATION CLIENT ON *.* TO 'repluser'@'%' IDENTIFIED BY '123456'; Query OK, 0 rows affected, 1 warning (0.01 sec) mysql> FLUSH PRIVILEGES; Query OK, 0 rows affected (0.01 sec) （编辑：云计算网_宿迁站长网） 【声明】本站内容均来自网络，其相关言论仅代表作者个人观点，不代表本站立场。若无意侵犯到您的权利，请及时与联系站长删除相关内容! |
