      mysql_install_db --datadir=/var/lib/mysql/3307 --user=mysql
      
    • 修改配置

      vi /etc/my.cnf
      [client]
      default-character-set = utf8
      
      [mysqld_multi]
      mysqld     = /usr/bin/mysqld_safe
      mysqladmin = /usr/bin/mysqladmin
      user       = root
      log        = /var/log/mysqld.multi.log
      
      [mysqld1]
      user=mysql
      port=3306
      datadir=/var/lib/mysql/3306
      socket=/var/lib/mysql/3306.sock
      pid-file=/tmp/mysql3306.pid
      log-error=/var/log/3306-error.log
      max_allowed_packet=1M
      table_open_cache=4
      thread_stack=128k
      character_set_server=utf8
      lower_case_table_names=1
      server-id=1
      log-bin = master3306-bin  #必须开启
      log-bin-index = master3306-bin.index  #必须开启
      
      [mysqld2]
      user=mysql
      port=3307
      datadir=/var/lib/mysql/3307
      socket=/var/lib/mysql/3307.sock
      pid-file=/tmp/mysql3307.pid
      log-error=/var/log/3307-error.log
      max_allowed_packet=1M
      table_open_cache=4
      thread_stack=128k
      character_set_server=utf8
      lower_case_table_names=1
      server-id=2
      log-bin=mysql3307-bin
      relay-log = relay-log
      relay-log-index = relay-log-index
      read-only = on
      

  7. 启动多实例

    mysqld_multi start
    
  8. 开放端口

    firewall-cmd --zone=public --add-port=3306/tcp --permanent
    firewall-cmd --zone=public --add-port=3307/tcp --permanent
    firewall-cmd --reload
    
  9. 连接主库

    grant replication slave on *.* to 'reply'@'localhost' identified by 'reply';
    FLUSH PRIVILEGES;
    
  10. 连接从库

    change master to master_host='localhost',master_user='repl',master_password='repl',master_port=3306;
    start slave;
    show slave status;## Slave_IO_Running:Yes, Slave_SQL_Running:Yes
    
  11. 测试

    • 主库

      create database test; -- 主库建库
      
    • 从库

      show databases; -- 从库查看
