Mysql 串連通過init_connect來初始化,官網說明:
伺服器為每個串連的用戶端執行的字串。該字串由一個或多個SQL語句組成,用分號字元分隔。例如,預設情況下每個用戶端工作階段都啟用自動認可模式。對於較舊的伺服器(在MySQL 5.5.8之前),沒有全域自動認可系統變數來指定預設情況下應禁用自動認可,但作為解決方案,init_connect可用於實現相同的效果:SET GLOBAL init_connect ='SET autocommit = 0';
1.建立資料庫及表
建立資料庫:
create database dba;
建立表:
create table accesslog(`thread_id` int primary key auto_increment, `time` timestamp, `localname` varchar(40), `machine_name` varchar(40));
thread_id : 記錄mysql 線程ID
time:記錄操作時間
localname:記錄操作遠程IP
machine_name:記錄使用者
2.變數配置
查看init_connect
+---------------+-------+| Variable_name | Value | |+---------------+-------+| init_connect | || init_file | || init_slave | |+---------------+-------+3 rows in set (0.00 sec)
組態變數
set global init_connect='insert into dba.accesslog(thread_id,time,localname,machine_name) values(connection_id(),now(),user(),current_user());';
再次查看init_connect
+---------------+-----------------------------------------------------------------------------------------------------------------------+| Variable_name | Value |+---------------+-----------------------------------------------------------------------------------------------------------------------+| init_connect | insert into dba.accesslog(thread_id,time,localname,machine_name) values(connection_id(),now(),user(),current_user()); || init_file | || init_slave | |+---------------+-----------------------------------------------------------------------------------------------------------------------+3 rows in set (0.00 sec)
3.為使用者賦記錄日誌許可權
grant select,insert,update on dba.accesslog to 'zhaohongming'@'%';
4.類比使用者操作添加刪除
[email protected]:(none) 11:34:49 >use sdlcqw;[email protected]:(none) 11:34:49 >crate table haha(cc int);[email protected]:(none) 11:34:49 >drop table haha;
5.查看binlog記錄
匯出binlog內容:
# mysqlbinlog mysql-bin.000079 > /root/9.txt
查詢log表:
[email protected]:(none) 11:39:41 >use dba;Reading table information for completion of table and column namesYou can turn off this feature to get a quicker startup with -ADatabase changed[email protected]:dba 11:39:50 >select * from accesslog limit 1;+-----------+---------------------+------------------------+----------------+| thread_id | time | localname | machine_name |+-----------+---------------------+------------------------+----------------+| 279950 | 2018-05-24 08:51:37 | [email protected] | [email protected]% |+-----------+---------------------+------------------------+----------------+1 row in set (0.00 sec)
6.查看binlog內容
上面的線程是279950
