【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.

*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 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;
