openstack2 sql配置，openstack2sql

control:172.21.120.101   102

   yum install -y mariadb  python2-PyMySQL

master:

yum install mariadb mariadb-server python2-PyMySQL  -y
 

node : 172.21.120.103   104

   yum install mariadb mariadb-server  -y

 

添加官方的配置文件   配置binlog  配置serverid

https://docs.openstack.org/install-guide/environment-sql-database-rdo.html

从库添加配置文件  配置serverid

初始化mysql

创建同步账号

到处配置

拷贝到从库

从库执行操作:导入

主库创建同步账号:

GRANT REPLICATION SLAVE,REPLICATION CLIENT ON *.* TO 'syncuser'@'192.168.7.%' IDENTIFIED BY '123456';  

查看备份文件master log file  和master log pos 在备份文件中  越22行左右 

MASTER_LOG_FILE='master-log.000006',MASTER_LOG_POS=120;

备库执行:

CHANGE MASTER TO    MASTER_HOST='192.168.7.1',MASTER_USER='syncuser',MASTER_PASSWORD='123456',MASTER_LOG_FILE='bin-log.000005', MASTER_LOG_POS=362;

start slave;

查看同步状态
