linux下搭建mysql主从

标签：

在master上创建repl账户，用于复制。

grant replication slave on *.* to ‘repl‘@‘%‘ 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;
