MySQL 主主复制搭建
设置bin-log，并配置对方为自己的Master
1. 搭建
1.1 Master1配置为Master2的主
Master配置(my.cnf)
[mysqld]
server_id=1
log-bin=/usr/local/mysql-5.6.16/log/mysql-bin
skip-slave-start # 启动时不启动slave的复制进程
auto_increment_offset=0
auto_increment_increment=2
replicate-do-db=test
replicate-ignore-db=mysql
启动Master1
./bin/mysqld_safe --defaults-file=/usr/local/mysql-5.6.16/my.cnf --user=mysql &
创建用于复制的用户
mysql > grant replication slave on *.* to ‘rep1‘@‘192.168.80.102‘ identified by ‘rep1‘;
备份数据并还原到Master2服务器
-- 设置读锁，数据无法更新
mysql > flush tables with read lock;
-- 查看开始复制的位置
mysql > show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 120 | | | |
+------------------+----------+--------------+------------------+-------------------+
-- 传输数据
tar -czf - data/ | ssh 192.168.80.102 "tar -xzf - -C /usr/local/mysql-5.6.16"
-- 解除锁定
mysql > unlock tables;
Master2配置(my.cnf)
[mysqld]
server_id=2 # Master和Slave之间唯一
log-bin=/usr/local/mysql-5.6.16/log/mysql-bin
skip-slave-start # 启动时不启动slave的复制进程
auto_increment_offset=1
auto_increment_increment=2
replicate-do-db=test
replicate-ignore-db=mysql
启动Master2
./bin/mysqld_safe --defaults-file=/usr/local/mysql-5.6.16/my.cnf --user=mysql &
配置复制参数
mysql > change master to
-> master_host=‘192.168.80.101‘,
-> master_port=3306,
-> master_user=‘rep1‘,
-> master_password=‘rep1‘,
-> master_log_file=‘mysql-bin.000001‘,
-> master_log_pos=120;
启动Master2的IO和SQL线程
mysql > start slave;
检查
mysql > show processlist \G
应出现以下信息:
State: Waiting for master to send event
State: Slave has read all relay log; waiting for the slave I/O thread to update it
或
mysql > show slave status \G
应出现以下信息:
Slave_IO_State: Waiting for master to send event
Slave_SQL_Running_State: Slave has read all relay log; waiting for the slave I/O thread to update it
1.2 Master2配置为Master1的主
对Master2执行show master status操作并对Master1执行change master to操作，检查。
