在上一实验的基础上实现。
?
?
?
cat /etc/my.cnf
[mysqld]
server_id=121
binlog_format=row
log_bin=/data/bin/mysql-bin
?
vim /etc/my.cnf
[mysqld]
server_id=121
binlog_format=row 建议添加
log_bin=/data/bin/mysql-bin(注意目录权限,可以用默认)
systemctl restart mariadb
?
?
?
?
?
?
?
cat /etc/my.cnf
[mysqld]
server_id=120(只要是唯一即可)
read_only
?
vim /etc/my.cnf
[mysqld]

read_only 建议添加

systemctl stop mariadb
\rm -rf /var/lib/mysql/*
systemctl start mariadb
