Question

我想在ubuntu服务器上创建主从复制。不同服务器上的（主服务器和从服务器）。我在master上制作了my.cnf（没有coments）文件：

!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mysql.conf.d/
[mysqld]
bind-address=my_server_ip
server-id=1
log_bin=/var/log/mysql/mysql-bin.log
binlog_do_db=indicators

然后我重新启动使用sudo service mysql restart并得到以下错误：

Job for mysql.service failed because the control process exited with error code. See "systemctl status mysql.service" and "journalctl -xe" for details

但是当我设置bind-address = 127.0.0.1时，它工作正常。

下面是使用的引用，其中bind-address应该是主服务器的地址

但它与下面的链接相符，其中说（在评论部分下）bind-address是奴隶的ip

https://dev.mysql.com/doc/refman/5.7/en/replication-howto-masterbaseconfig.html

systemctl status mysql.service ，如上面的错误代码

Answer 1

下面是使用的引用，其中bind-address应该是主服务器的地址

不，不。它说“用服务器的IP地址替换标准IP地址”。 “主人”这个词没有出现。

但它与下面的链接相符，其中说（在评论部分下）bind-address是奴隶的ip

不，不。它说'你必须确保 slave的地址或主机名与bind-address设置相匹配'。

您无法绑定到非本地IP地址。

无法在mysql
