配置主数据库：
my.cnf：
server-id = 1
log-bin
重启数据库
登录并查看：
[root@Mysql-server ~]# mysql -uroot -p199429
mysql> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | ON |
+---------------+-------+
mysql> show variables like 'server_id';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| server_id | 1 |
+---------------+-------+
建立主从复制账号：
mysql> grant replication slave on *.* to 'rep'@'192.1.1.%' identified by '199429';
mysql> select user,host from mysql.user;
+-----------+-----------+
| user | host |
+-----------+-----------+
| root | 127.0.0.1 |
| bbs | 192.1.1.% |
| keer | 192.1.1.% |
| rep | 192.1.1.% |
| wordpress | 192.1.1.% |
| root | localhost |
+-----------+-----------+
实现对主数据库锁表只读：
mysql> flush table with read lock;
Query OK, 0 rows affected (0.00 sec)
mysql> show variables like '%timeout%';
+----------------------------+----------+
| Variable_name | Value |
+----------------------------+----------+
| connect_timeout | 10 |
| delayed_insert_timeout | 300 |
| innodb_lock_wait_timeout | 50 |
| innodb_rollback_on_timeout | OFF |
| interactive_timeout | 28800 |#####
| lock_wait_timeout | 31536000 |
| net_read_timeout | 30 |
| net_write_timeout | 60 |
| slave_net_timeout | 3600 |
| wait_timeout | 28800 |#####
+----------------------------+----------+
10 rows in set (0.00 sec)
查看主库状态：
mysql> show master status;
+-------------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+-------------------------+----------+--------------+------------------+
| Mysql-server-bin.000001 | 962 | | |
+-------------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
新开窗口备份导出数据：
[root@Mysql-server ~]# mkdir -p /server/backup/
[root@Mysql-server ~]# mysqldump -uroot -p199429 --events -A -B |gzip >/server/backup/mysql_bak.$(date +%F).sql.gz
在此查看主库状态是否变化：
mysql> show master status;
+-------------------------+----------+--------------+------------------+
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB |
+-------------------------+----------+--------------+------------------+
| Mysql-server-bin.000001 | 962 | | |
+-------------------------+----------+--------------+------------------+
1 row in set (0.00 sec)
从数据库：
配置文件my.cnf
server-id = 2 ####保证唯一性
重启从数据库
登录从数据库：
[root@Mysql-server_02 backup]# mysql -uroot -p199429 -S /data/3306/mysql.sock
mysql> show variables like 'log_bin';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| log_bin | OFF |
+---------------+-------+
1 row in set (0.00 sec)
mysql> show variables like 'server_id';
+---------------+-------+
| Variable_name | Value |
+---------------+-------+
| server_id | 3 |
+---------------+-------+
恢复MySQLdump的数据
[root@Mysql-server_02 backup]# cd /server/backup/
[root@Mysql-server_02 backup]# gzip -d mysql_bak.2017-03-23.sql.gz
[root@Mysql-server_02 backup]# mysql -uroot -p'199429' -S /data/3306/mysql.sock
CHANGE MASTER TO
-> MASTER_HOST='192.1.1.11',
-> MASTER_PORT=3306,
-> MASTER_USER='rep',
-> MASTER_PASSWORD='199429',
-> MASTER_LOG_FILE='Mysql-server-bin.000001',
-> MASTER_LOG_POS=962;
费登录状态执行方法：
[root@Mysql-server_02 backup]# mysql -uroot -p'199429' -S /data/3306/mysql.sock<< EOF
CHANGE MASTER TO
MASTER_HOST='192.1.1.11',
MASTER_PORT=3306,
MASTER_USER='rep',
MASTER_PASSWORD='199429',
MASTER_LOG_FILE='Mysql-server-bin.000001',
MASTER_LOG_POS=962;
EOF
实际修改从库中的master.info文件
[root@Mysql-server_02 backup]# cat /data/3306/data/master.info
