mysql中的主主复制

mysql中的主主复制

我是 mysql 新手,正在尝试在 mysql 中建立主主复制

在第一台服务器上,我已将这些行添加到 my.cnf 的 mysqld 部分(mysql Ver 14.12 Distrib 5.0.77,适用于 redhat-linux-gnu (i686) 使用 readline 5.1)

datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
log-bin=/var/lib/mysql/mysql-bin.log
binlog-do-db=sample1  
binlog-ignore-db=mysql            
binlog-ignore-db=information_schema
binlog-ignore-db=test2
binlog-ignore-db=sample3
binlog-ignore-db=example3
binlog-ignore-db=endpoints
binlog-ignore-db=meetme
binlog-ignore-db=test
binlog-ignore-db=sample2

server-id=1
master-host = 192.xxx.x.xxx
master-user = abc
master-password = abc_pass
master-connect-retry = 60

relay-log = /var/lib/mysql/slave-relay.log
relay-log-index = /var/lib/mysql/slave-relay-log.index

在第二台服务器上,我已将这些行添加到 my.cnf 的 mysqld 部分(mysql Ver 14.14 Distrib 5.1.41,适用于 debian-linux-gnu (i486) 使用 readline 6.1)

server-id=2

master-host = 192.xxx.x.xxx
master-user = xyz
master-password = xyz_pass
master-connect-retry = 60

relay-log = /var/lib/mysql/slave-relay.log
relay-log-index = /var/lib/mysql/slave-relay-log.index

log-bin = /var/lib/mysql/mysql-bin.log
binlog-do-db = sample1
binlog-ignore-db=mysql
binlog-ignore-db=information_schema
binlog-ignore-db=phpmyadmin

在第一台服务器上,从属状态是

不知道为什么 Slave_IO_Running 为否。

我尝试了很多次来启动复制,但仍然无法启动复制。我也评论过

#bind-address           = 127.0.0.1

#skip-external-locking

我需要你的帮助。请发送你对此问题的建议和解决方案。

提前致谢。

问候,pradeep

答案1

看起来这是两个 mysql 服务器之间的通信问题。Last_IO_Error:连接 master 时出错'[电子邮件保护]:3306。

您是否验证过
1) 192.xxx.x.xxx 是否正在监听 192.xx.x.xxx 或 0.0.0.0/0
2) 另一台服务器(我们称之为 192.xx.x.yyy)是否可以连接到它?使用 mysql、netcat 或其他工具进行确定

似乎也没有输入主日志文件或位置。我确信配置中还有其他问题,读取您的配置和粘贴非常困难
