发现直接连接MGR节点是正常的,可以写入,但通过ProxySQL连接就无法show\select\insert 等 使用sysbench对ProxySQL报以下错误:
1FATAL: `thread_run' function failed: /usr/share/sysbench/oltp_insert.lua:47: SQL error, errno = 9001, state = 'HY000': Max connect timeout reached while reaching hostgroup 10 after 10001ms 2FATAL: `thread_run' function failed: /usr/share/sysbench/oltp_insert.lua:47: SQL error, errno = 9001, state = 'HY000': Max connect timeout reached while reaching hostgroup 10 after 10000ms 3FATAL: `thread_run' function failed: /usr/share/sysbench/oltp_insert.lua:47: SQL error, errno = 9001, state = 'HY000': Max connect timeout reached while reaching hostgroup 10 after 10001ms 4FATAL: `thread_run' function failed: /usr/share/sysbench/oltp_insert.lua:47: SQL error, errno = 9001, state = 'HY000': Max connect timeout reached while reaching hostgroup 10 after 10000ms 5
select * from stats_mysql_processlist;有67个sleep的命令. select * from stats_mysql_connection_pool; 10组只有一个连接 根据官方问题记录,对比检查,没有发现问题(已经runtime\配置也是对的.)无奈重启一次ProxySQL,OK正常了.
