在启动管理init.d里关于mysql的命令有

sudo /etc/init.d/mysql start|stop|restart|reload|force-reload|status

sudo apt-get install mysql-server 


GRANT ALL PRIVILEGES ON *.* TO root@localhost IDENTIFIED BY "123456"; 


CREATE DATABASE xoops;


其一:


mysql>GRANT ALL PRIVILEGES ON xoops.* TO xoops_root@"%" IDENTIFIED BY "654321";


允许xoops_root用户可以从任意机器上登入MySQL。


其二:


$sudo gedit /etc/mysql/my.cnf


老的版本中


>skip-networking => # skip-networking


新的版本中


>bind-address=127.0.0.1 => bind-address= 你机器的IP


这样就可以允许其他机器访问MySQL了。 


还有最后一步(无法远程时使用这条指令。)

mysql>FLUSH PRIVILEGES

配置同步关键:

1.主服务器上配置my.cnf 开启日志功能,配置server_id,

2.重启mysql服务 etc/init.d/mysql restart

3.主服务器上新增具有replication权限的账户 

grant replication slave on to 'www'@'%' identified by '123.asd'


3.从服务器上配置my.cnf,配置server_id

4.重启从服务器mysql服务

5.配置同步。

change master to master_host=‘192.168.1.118’, 主服务器IP

master_user='www', 主服务器开启的复制权限账户

master_password='123.asd',

master_log_file='mysql-bin.000001',  在主服务器上查询 show master status/G 出来的日志文件名

master_log_pos='309';                 位置文件名


6.重启从服务器mysql服务即可



主主同步只需要在主从服务器上做上述相同配置即可。


修改my.cnf文件前记得关闭MYSQL服务


连接数据库问题,主要看LOG
