新环境搭建Mysql主从
环境信息：
1、Mysql安装
参考http://blog.itpub.net/28536251/viewspace-2138854分别在两节点安装Mysql。
2、主节点配置
（1）修改配置文件
[root@dbrac16 ~]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
user=mysql
symbolic-links=0
character-set-server=utf8
server-id = 8416
log-bin=/usr/local/mysql/data/mysql-bin
binlog_format=mixed
slow-query-log
long_query_time=3
log-output=TABLE
expire_logs_days = 7
event_scheduler=1
innodb_file_per_table=1
innodb_log_file_size=536870912
innodb_buffer_pool_size=1073741824
max_binlog_size=1073741824
log_bin_trust_function_creators=1
innodb_stats_on_metadata=0
max_connect_errors = 1000000
max_connections = 5000
skip_name_resolve = 1
explicit_defaults_for_timestamp=true
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/usr/local/mysql/my.pid
[client]
socket=/usr/local/mysql/mysql.sock
[mysql]
prompt=(\u@\h)[\d]\_
（2）重启Mysql
[root@dbrac16 ~]# /etc/init.d/mysqld restart
Shutting down MySQL..... SUCCESS!
Starting MySQL. SUCCESS!
（3）创建复制用户
(root@localhost)[(none)] GRANT REPLICATION SLAVE ON *.* TO 'repl'@'10.163.84.%' IDENTIFIED BY 'repl';
Query OK, 0 rows affected, 1 warning (0.06 sec)
(root@localhost)[(none)] flush privileges;
Query OK, 0 rows affected (0.08 sec)
（4）获取日志信息
(root@localhost)[(none)] show master status;
+------------------+----------+--------------+------------------+-------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | Executed_Gtid_Set |
+------------------+----------+--------------+------------------+-------------------+
| mysql-bin.000002 | 154 | | | |
+------------------+----------+--------------+------------------+-------------------+
1 row in set (0.01 sec)
3、从节点配置
（1）修改配置文件
[root@dbrac17 ~]# vim /etc/my.cnf
[mysqld]
datadir=/usr/local/mysql/data
socket=/usr/local/mysql/mysql.sock
user=mysql
symbolic-links=0
character-set-server=utf8
server-id=8417
slow-query-log
long_query_time=3
log-output=TABLE
expire_logs_days = 7
event_scheduler=1
innodb_file_per_table=1
innodb_log_file_size=536870912
innodb_buffer_pool_size=1073741824
max_binlog_size=1073741824
log_bin_trust_function_creators=1
innodb_stats_on_metadata=0
max_connect_errors = 1000000
max_connections = 5000
skip_name_resolve = 1
explicit_defaults_for_timestamp=true
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/usr/local/mysql/my.pid
[client]
socket=/usr/local/mysql/mysql.sock
[mysql]
prompt=(\u@\h)[\d]\_
（2）删除auto.cnf文件
[root@dbrac17 ~]# rm /usr/local/mysql/data/auto.cnf
rm: remove regular file `/usr/local/mysql/data/auto.cnf'? y
（3）重启Mysql
[root@dbrac17 ~]# /etc/init.d/mysqld restart
Shutting down MySQL..... SUCCESS!
Starting MySQL. SUCCESS!
（4）配置到主节点的连接
(root@localhost)[(none)] CHANGE MASTER TO MASTER_HOST='10.163.84.16',MASTER_PORT=3306,MASTER_USER='repl',MASTER_PASSWORD='repl',MASTER_LOG_FILE='mysql-bin.000002',MASTER_LOG_POS=154;
Query OK, 0 rows affected, 2 warnings (0.05 sec)
（5）启动复制并查看状态
(root@localhost)[(none)] start slave;
Query OK, 0 rows affected (0.03 sec)
(root@localhost)[(none)] show slave status\G

4、测试
（1）主节点创建库，表并插入数据
(root@localhost)[(none)] create database test;
Query OK, 1 row affected (0.01 sec)
(root@localhost)[(none)] use test;
Database changed
(root@localhost)[test] create table tb1(id int);
Query OK, 0 rows affected (0.07 sec)
(root@localhost)[test] insert into tb1 values(1);
Query OK, 1 row affected (0.04 sec)
（2）从节点查看
(root@localhost)[(none)] use test
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A
Database changed
(root@localhost)[test] select * from tb1;
