mysql集群搭建，主主复制

1：mysql搭建远程连接

https://www.cnblogs.com/davidgu/p/3706663.html

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;
+--------------------+

| autocreatetable    |
| cms_boot           |
