2: 两台主机能够相互通信 ,使用ping
C:\Users\lenovo>ping 192.168.100.91 正在 Ping 192.168.100.91 具有 32 字节的数据:
来自 101.4.112.14 的回复: TTL 传输中过期。
来自 101.4.112.14 的回复: TTL 传输中过期。
来自 101.4.112.14 的回复: TTL 传输中过期。
来自 101.4.112.14 的回复: TTL 传输中过期。 192.168.100.91 的 Ping 统计信息:
数据包: 已发送 = 4，已接收 = 4，丢失 = 0 (0% 丢失)，
3：mysql复制，备份
liyafei OEM:~$ mysqldump -hlocalhost -uroot -p1367356 test>test.sql
4： 配置主从复制

4.1： 配置主服务器，
a: ubuntu 14.04,ip 192.168.100.91 作为主服务器
在/etc/mysql/my.cnf 文件里面 mysqld下面添加
log-bin=mysql-bin
server-id=1 #唯一
b: windows 10 ，192.168.100.31作为从服务器
在my.ini中修改
log-bin=mysql-bin
server-id=160
4.2：在主服务上面授予从服务器权限。
# mysql> create user 'repl'@'192.168.100.31' identified by 'slavepass';
Query OK, rows affected (0.00 sec)
# mysql> grant replication slave on *.* to 'repl'@'192.168.100.31'; -- 权限授予了192.168.100.31 root， 所以这两步可以不用了
Query OK, rows affected (0.00 sec)
mysql> flush privileges;
Query OK, rows affected (0.00 sec)
mysql> show master status;
| File | Position | Binlog_Do_DB | Binlog_Ignore_DB | +--
| mysql-bin. | | | | +---------------
row in set (0.00 sec)
4.3: 从服务器指向主服务器，和mysql-bin二进制文件和位置position。
mysql> change master to
-> master_host='192.168.100.91',
-> master_user='root',
-> master_password='',
-> master_log_file='mysql-bin.000006',
-> master_log_pos=;
Query OK, rows affected (0.06 sec) mysql> start slave;
Query OK, rows affected (0.00 sec) mysql> show slave status; # 查看从服务器状态， io-running和 sql-running为yes

row in set (0.00 sec)
4.4在主服务器上面创建表
mysql> create database linux1;
Query OK, row affected (0.02 sec)
mysql> use linux1;
4.5 从服务器自动改变
mysql> show databases;
