【问题描述】:
我从我们的 Zabbix 服务器收到一封电子邮件警报,说它的数据库已关闭,我检查了日志并找到了以下条目。谁能解释一下这是什么意思以及为什么会发生?
1828:20160224:073113.549 [Z3005] query failed: [1317] Query execution was interrupted [select h.hostid,h.host,h.name,t.httptestid,t.name,t.variables,t.headers,t.agent,t.authentication,t.http_user,t.http_password,t.http_proxy,t.retries,t.ssl_cert_file,t.ssl_key_file,t.ssl_key_password,t.verify_peer,t.verify_host from httptest t,hosts h where t.hostid=h.hostid and t.nextcheck<=1456320673 and mod(t.httptestid,10)=5 and t.status=0 and h.proxy_hostid is null and h.status=0 and (h.maintenance_status=0 or h.maintenance_type=0)]
1828:20160224:073113.549 [Z3005] query failed: [2006] MySQL server has gone away [select min(t.nextcheck) from httptest t,hosts h where t.hostid=h.hostid and mod(t.httptestid,10)=5 and t.status=0 and h.proxy_hostid is null and h.status=0 and (h.maintenance_status=0 or h.maintenance_type=0)]
1828:20160224:073113.549 [Z3001] connection to database 'zabbix' failed: [2002] Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
1828:20160224:073113.549 database is down: reconnecting in 10 seconds
然后我看到了这些日志:
1843:20160224:073119.428 [Z3005] query failed: [2006] MySQL server has gone away [begin;]
1828:20160224:073123.549 database connection re-established
不确定它是如何连接的!
【问题讨论】:
-
您的管理员是否安装了软件更新?
-
不,我没有安装任何软件更新。
-
检查 mysqld 服务是否在您安装/配置了 Zabbix mysql DB 的服务器上运行。尝试例如:sudo -E service mysqld restart(使用具有 sudo 访问权限的用户)或使用 root。
-
我没有看到 mysqld 服务,但我可以看到 'mysql' 服务正在运行!
