MySQL主从复制
准备两个Mysql服务器
配置主机服务器 192.168.199.101
vim my.cnf
server-id=1
log_bin=/var/log/mysql/mysql-bin.log保存重启mysql
mysql -uroot -proot
mysql>show master status;

+------------------+----------+--------------+------------------+
//创建授权账号 授权账号为 slave 密码为 123456 ip地址为192.168.199.102 的从服务器
grant replication slave on *.* to [email protected] identified by '123456' 配置从服务器 192.168.199.102
vim my.cnf
server-id=21
relay_log=/var/log/mysql/mysql-relay-bin.log保存重启mysql
mysql -uroot -proot
stop slave;
//开启监听 此处master_log_file和master_log_pos与服务器192.168.199.101对应
change master to master_host='192.168.199.101', master_port=3306, master_user='slave', master_password='123456', master_log_file='mysql-bin.000002', master_log_pos=76481;
start slave;
//查看监听情况
show slave status\G;
