【第一部分】 Master – Lebron – 192.168.1.122
1. 开放3306端口
[root@lebron sysconfig]# vim /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.
*filter
:INPUT ACCEPT [0:0]
:FORWARD ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -i lo -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
#mysql port
-A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
2. 重启网络
[root@lebron sysconfig]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
3. 开启binlog
[root@lebron log]# vim /etc/my.cnf
[mysqld]
log-bin=mysql-bin
server-id=1
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
4. 重启mysqld
service mysqld restart
5. 登录mysql，创建复制用户
create user 'lxl'@'192.168.%' identified by '123456';
6. 赋权
grant replication slave on *.* to lxl@'192.168.%';
7. 创建测试数据库
create database lixinlei;
8. 创建测试表
use lixinlei;
create table t(id int, c1 varchar(10), primary key(id));
9. 插入测试数据
insert into t values(1,'aa'),(2,'bb'),(3,'cc');
10. 退出mysql
quit
11. 备份数据库
[root@lebron tmp]# cd /tmp
[root@lebron tmp]# mysqldump --single-transaction --master-data=2 --triggers --routines --all-databases -uroot -p > all.sql
12. 拷贝备份文件到Slave – Kyrie
[root@lebron tmp]# scp all.sql root@192.168.1.123:/tmp
【第二部分】 Slave – Kyrie – 192.168.1.123
1. 开放3306端口
[root@lebron sysconfig]# vim /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall
# Manual customization of this file is not recommended.

-A INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT
#mysql port
-A INPUT -p tcp -m tcp --dport 3306 -j ACCEPT
-A INPUT -j REJECT --reject-with icmp-host-prohibited
-A FORWARD -j REJECT --reject-with icmp-host-prohibited
COMMIT
2. 重启网络
[root@lebron sysconfig]# service iptables restart
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
iptables: Applying firewall rules: [ OK ]
3. 开启binlog
[root@lebron mysql]# vim /etc/my.cnf
[mysqld]
log-bin=mysql-slave
server-id=2
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
symbolic-links=0
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
4. 重启mysqld
service mysqld restart
5. 检查备份文件是否拷贝成功
[root@kyrie ~]# cd /tmp
[root@kyrie tmp]# ls
all.sql yum.log
6. 恢复
[root@kyrie tmp]# mysql -uroot -p < all.sql
7. 记录Master的日志文件&日志点
[root@kyrie tmp]# more all.sql
MASTER_LOG_FILE='mysql-bin.000001',
MASTER_LOG_POS=154;
8. 登录mysql，检查恢复是否成功
[root@lebron tmp]# mysql -uroot -p'y;WQx*H>?78K'
mysql> show databases;

9. 配置复制链路
mysql> change master to master_host='192.168.1.122',
-> master_user='lxl',
-> master_password='123456',
-> master_log_file='mysql-bin.000001',
-> master_log_pos=154;
10. 启动Slave
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
11. 查看Slave状态
mysql> show slave status\G;
