在master上创建repl账户，用于复制。

grant replication slave on *.* to [email protected]%‘ identified by ‘P@$$W0rd‘;

flush privileges;

与windows下搭建mysql主从的区别：

二进制日志的路径格式不一样

master:

my.cnf部分配置(master):

thread_handling = pool-of-threads

thread_pool_oversubscribe = 10

skip-name-resolve

# Replication Master Server (default)

# binary logging is required for replication

#log-bin=mysql-bin

# binary logging format - mixed recommended

binlog_format=mixed

# required unique id between 1 and 2^32 - 1

# defaults to 1 if master-host is not set

# but will not function as a master if omitted

server-id     = 1

expire_logs_days        = 10

max_binlog_size         = 100M

log_bin                 = /var/lib/mysql/mysql-bin.log   #确保此文件可写

read-only              =0  #主机，读写都可以

binlog-do-db         =yourdb   #需要备份数据，多个写多行

binlog-ignore-db    =mysql #不需要备份的数据库，多个写多行

slave:

master：

show variables like ‘%log_bin%‘;

show master status

slave：

stop slave;

change master to

master_host=‘192.168.103.56‘,

master_user=‘repl‘,

master_password=‘P@$$W0rd‘,

master_log_file=‘mysql-bin.000002‘,

master_log_pos=120;

start slave;

show slave status;
