percona mysql5.7进程出现大量unauthenticated user解决记录
2024-08-26 16:24:10
现象：http://task.chinasoft.com.wx/
所有任务能打开，我的任务打开很慢
有些人能用，有些人不能用，数据库出现大量的未认证用户连接，连接数利用率超过70%
重启nginx,apache,mysql没有用
问题依旧
Kill 掉cdn的推送延迟脚本，问题依旧
后面不知道是否是重启 php-fpm 解决？未知
# 批量kill mysql的进程

do

后续还是经常出现类似的情况，用kill干掉回话也不行，后面不知道修改了哪里又好了，具体的修改内容如下，供参考
已经做过的操作：
1.调整my.cnf参数
#加大连接池数
thread_pool_size = 128
# 加到最大thread数量
thread_pool_max_threads = 512
table_open_cache = 32768
# 跳过dns解析
skip-name-resolve
# 减小超时时间
wait_timeout = 60
interactive_timeout = 60
# 增大最大连接数
max_connections = 1200
max_connect_errors = 10000
max_allowed_packet = 512M
back_log = 49152
# 更改binlog日志为row类型，之前是mixed
binlog_format=row
在Linux下这个参数的值不能大于系统参数tcp_max_syn_backlog的值
通过以下命令可以查看当前值：cat /proc/sys/net/ipv4/tcp_max_syn_backlog
通过以下命令进行修改sysctl -w net.ipv4.tcp_max_syn_backlog=98304
[root@newcms:~]# cat /proc/sys/net/ipv4/tcp_max_syn_backlog
16384
[root@newcms:~]# sysctl -w net.ipv4.tcp_max_syn_backlog=98304
net.ipv4.tcp_max_syn_backlog = 98304
[root@newcms:~]# cat /proc/sys/net/ipv4/tcp_max_syn_backlog
98304
# 观察mysql日志，修改相关的参数
2019-09-28T00:31:55.707617Z 0 [ERROR] Threadpool could not create additional thread to handle queries, because the number of allowed threads was reached. Increasing 'thread_pool_max_threads' parameter can help in this situation.
If 'extra_port' parameter is set, you can still connect to the database with superuser account (it must be TCP connection using extra_port as TCP port) and troubleshoot the situation. A likely cause of pool blocks are clients that lock resources for long time. 'show processlist' or 'show engine innodb status' can give additional hints.
# 修改my.cnf的参数
thread_pool_max_threads = 512
2.跳转php.ini参数，加强对session的回收
3.删除一些表
4.将非应用连接的db账号权限全部取消，排除连接干扰
之前应用连接的账号权限比较大：对所有的数据库都有增删改查的权限，将权限控制在部分数据库中
5.查看数据库的查询状态：
[root@newcms:~]# mysqladmin -uroot -p status -i 1
