MySQL 不再記錄查詢

  • December 21, 2018

前段時間我將我的 MySQL 伺服器更新為v5.6：

SELECT VERSION();
5.6.30-0ubuntu0.14.04.1

現在查詢日誌無法正常工作，儘管其中的配置/etc/mysql/my.cnf似乎是正確的：

[mysqld]
general_log_file = /var/log/mysql/mysql.log
general_log      = 1
log              = /var/log/mysql-query.log # Added now, but it also hasn't helped.

日誌文件存在並且對mysql使用者是可寫的：

$ ls -lia /var/log/mysql | grep "mysql-query"
393371 -rwxrwxrwx  1 mysql adm   0 Jun  5 17:09 mysql-query.log
$ ls -lia /var/log | grep "mysql.log"
403924 -rwxrwxrwx  1 mysql adm   0 Jun  5 16:35 mysql.log

如何再次獲取 MySQL 日誌記錄查詢？

更新

附加資訊：

錯誤日誌顯示（重新）啟動伺服器時的一些錯誤。

也許它以某種方式與這個問題有關。

還需要：

log_output = 'FILE'

同時，您可能在 mysql.general_log 表中添加了很多內容。做SELECT * FROM mysql.general_log LIMIT 11;

幾天前我遇到了類似的問題，沒有什麼建議。

  1. 檢查以下命令的輸出：

show variables like '%general%'; 2. 如果輸出列出一般日誌文件，但仍然沒有記錄查詢，請修改以下參數。

general_log = ON

general_log_file = /var/log/mysql/mysql.log

  1. 如果還是不行，請檢查/var/log/mysql/mysql.log path.更改訪問權限的訪問權限，如下所示：

chmod 755 /var/log/mysql/mysql.log

我希望這個答案能解決日誌查詢問題。謝謝你。
