keepalived+haproxy+mycat+mysql高可用搭建配制

mysql双主同步配置：

mysql1服务器的my.cnf配置：

server-id=1

log_bin=bin_log 

binlog-do-db=ry-vue

slave_parallel_type='logical_clock'  
 
slave_parallel_workers=4  

relay-log=relay-bin  

relay-log-index=relay-bin.index  

replicate-do-db=ry-vue 


auto_increment_offset = 1

auto_increment_increment = 2
 

mysql2服务器 的my.ini配置：

server-id=2  

log_bin=bin_log

binlog-do-db=ry-vue

 
slave_parallel_type='logical_clock'  

slave_parallel_workers=4  

relay-log=relay-bin  

relay-log-index=relay-bin.index  

replicate-do-db=ry-vue 

auto_increment_offset = 2

auto_increment_increment = 2

 

进入mysql1：

• CREATE USER '用户名'@'MySql2服务器ip' IDENTIFIED BY '密码';

• GRANT REPLICATION SLAVE ON *.* TO '用户名'@'MySql2服务器ip';

• flush privileges;

• 然后输入

• mysql> show master status;
  +----------------+----------+--------------+------------------+-------------------+
  | File           | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
  +----------------+----------+--------------+------------------+-------------------+
  | bin_log.000001 |      790 | ry-vue       |                  |                   |
  +----------------+----------+--------------+------------------+-------------------+
  1 row in set (0.01 sec)

   

• 我们会看到：（记住 File 和 Position）

• 进入mysql2：

• CHANGE MASTER TO
  master_host = 'MySql1服务器ip',   
  master_user = '用户名',  
  master_password = '密码',  
  master_log_file = 'bin_log.000001',  
  master_log_pos = 790;

  mysql> start slave;
  Query OK, 0 rows affected (0.01 sec)

  mysql> show slave status\G
