如果这次连接超时,根据其它参数的设置,ProxySQL将会重新尝试建立连接,直到达到了最大重连次数而每秒生成报错信息(此时ProxySQL会自动避开后端MySQL,即不再连接,但会不断报错),或者达到了连接的最终截止时间(见mysql-connect_timeout_server_max)而报另一种错误。 mysql-connect_timeout_server mysql-connect_timeout_serv...

代表的是ProxySQL当前生效的配置,包括 global_variables, mysql_servers, mysql_users, mysql_query_rules。无法直接修改这里的配置,必须要从下一层load进来。该层级的配置时在proxysql管理库(sqlite)的main库中以runtime_开头的表,这些表的数据库无法直接修改,只能从其他层级加载;该层代表的是ProxySQL当前生效的正在使...

1)mysql-monitor_ping_interval 执行ping检查的频率,以毫秒为单位 2)mysql-monitor_ping_timeout Ping超时时间(以毫秒为单位)。 3)mysql-monitor_ping_max_failures 如果主机连续丢失了 mysql-monitor_ping_max_failures 次ping,则MySQL_Monitor会通知MySQL_Hostgroup_Manager,告知该节点无法访问,应立即终止所有连接。
