systemctl restart mysqld
vim /etc/my.cnf
server-id = 2 #三台服务器的 server-id 不能一样
log_bin = mysql-bin
binlog_format = mixed
log-slave-updates = true
relay-log = relay-log-bin
relay-log-index = slave-relay-bin.index
systemctl restart mysqld
ln -s /usr/local/mysql/bin/mysql /usr/sbin/
ln -s /usr/local/mysql/bin/mysqlbinlog /usr/sbin/
