Mysql Master-Slave配置实验说明文档
一、主机信息
mysql1(master) 192.168.100.11 rhel5.4_x86 mysql-5.6.12.tar.gz
mysql2(slave) 192.168.100.12 rhel5.4_x86 mysql-5.6.12.tar.gz
二、mysql1(master)主机
1.停止mysql服务
2.配置文件
安装mysql软件自动生成配置文件my.cnf
[root@mysql1 ~]# cd /usr/local/mysql/
[root@mysql1 mysql]# vi my.cnf
文件末尾添加
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
######### Add Start ########
server-id=1 ## 服务器编号
log_bin=mysql-bin.log ##日志名称
read-only=0 ## 数据库可以读写
binlog-do-db=test ## 需要复制的数据库
binlog-ignore-db=mysql ## 排除不需要复制的数据库
######### Add End ########
3.启动mysql服务
4.建立复制和启动slave服务用户
mysql> GRANT REPLICATION SLAVE ON *.* TO 'rep'@'%' IDENTIFIED BY '123456' WITH GRANT OPTION;
Query OK, 0 rows affected (0.06 sec)
5.刷新系统表
mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)
6.显示master状态
mysql> show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000001 | 414 | test | mysql | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.00 sec)
mysql>
三、mysql2(slave)主机
1.停止mysql服务
2.配置文件
安装mysql软件自动生成配置文件my.cnf
[root@mysql1 ~]# cd /usr/local/mysql/
[root@mysql1 mysql]# vi my.cnf
文件末尾添加
# read_rnd_buffer_size = 2M
sql_mode=NO_ENGINE_SUBSTITUTION,STRICT_TRANS_TABLES
######### Add Start ########
server-id=2
######### Add End ########
3.启动mysql服务
4.执行同步SQL语句
mysql> change master to master_host='192.168.100.11',master_user='rep',master_password='123456',master_log_file='mysql-bin.000001',master_log_pos=414;
Query OK, 0 rows affected, 2 warnings (0.13 sec)
5.启动同步服务
mysql> start slave;
Query OK, 0 rows affected (0.01 sec)
6.显示同步服务状态
mysql> show slave status\G;
*************************** 1. row ***************************
Slave_IO_State: Waiting for master to send event

三、验证主从线程
1.mysql1(master)主机
slave进程启动后，执行以下命令，查看master主机日志发送线程
mysql> show processlist;
+----+------+----------------------+------+-------------+------+-----------------------------------------------------------------------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+------+----------------------+------+-------------+------+-----------------------------------------------------------------------+------------------+
| 1 | root | localhost | test | Query | 0 | init | show processlist |
| 2 | rep | 192.168.100.12:48981 | NULL | Binlog Dump | 718 | Master has sent all binlog to slave; waiting for binlog to be updated | NULL |
+----+------+----------------------+------+-------------+------+-----------------------------------------------------------------------+------------------+
2 rows in set (0.00 sec)
mysql>
2.mysql2(slave)主机
检查同步进程，接收master bin-log和应用传递过来的replay-log两个相关线程
mysql> show processlist;
+----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+
| Id | User | Host | db | Command | Time | State | Info |
+----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+
| 1 | root | localhost | NULL | Query | 0 | init | show processlist |
| 2 | system user | | NULL | Connect | 549 | Waiting for master to send event | NULL |
| 3 | system user | | NULL | Connect | 549 | Slave has read all relay log; waiting for the slave I/O thread to update it | NULL |
+----+-------------+-----------+------+---------+------+-----------------------------------------------------------------------------+------------------+
3 rows in set (0.00 sec)
mysql>
四、执行master-slave复制验证
1.mysql1(master)主机
mysql> use test
Database changed
mysql> show tables;
Empty set (0.00 sec)
mysql> CREATE TABLE tasks(Id INT primary key AUTO_INCREMENT,
-> Title VARCHAR(20),
-> Done BOOL,
-> Description VARCHAR(200)
-> );
Query OK, 0 rows affected (0.29 sec)
mysql> CREATE TABLE users(Id int primary key AUTO_INCREMENT,
-> UserName VARCHAR(20) not null,
-> Password VARCHAR(20) not null,
-> Role VARCHAR(20),
-> Description VARCHAR(200)
-> );
Query OK, 0 rows affected (0.02 sec)
mysql> insert into tasks values(1,"Buy groceries",0,"Milk, Cheese, Pizza, Fruit, Tylenol");
insert into tasks values(2,"Learn Python",0,"Need to find a good Python tutorial on the web");
insert into tasks values(3,"Flask",0,"Login,WTF,Mail");
Query OK, 1 row affected (0.09 sec)
mysql> insert into tasks values(2,"Learn Python",0,"Need to find a good Python tutorial on the web");
Query OK, 1 row affected (0.01 sec)
mysql> insert into tasks values(3,"Flask",0,"Login,WTF,Mail");
Query OK, 1 row affected (0.00 sec)
mysql> insert into tasks values(4,"MySQL",0,"InoDB");
Query OK, 1 row affected (0.00 sec)
mysql>
mysql> insert into users values(1,"admin","admin","administrator","administrator");
Query OK, 1 row affected (0.00 sec)
mysql> insert into users values(2,"user","123456","User","User");
Query OK, 1 row affected (0.01 sec)
mysql> show tables;
+----------------+

+----------------+
2 rows in set (0.00 sec)
mysql> select * from tasks;

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'root' WITH GRANT OPTION;
flush privileges; (刷新系统表)
2.远程访问
mysql -h 远程主机IP（名称） -u root -P 3306（端口） -p
