1. 列印大於2023年1月3號的日誌

shell> gawk -f '''

}' /usr/local/nginx/logs/error.log
2015/01/04
13:22:05 [notice] 4644#0
: signal process started
2015/01/04
21:08:07 [notice] 7135#0
: signal process started
2015/01/11
20:59:24 [notice] 5201#0
: signal process started
2015/01/12
23:31:29 [notice] 5121#0: signal process started

2. 列印1月3號到1月12號之間的日誌

shell> gawk -f '''

}' /usr/local/nginx/logs/error.log 
2015/01/04
13:22:05 [notice] 4644#0
: signal process started
2015/01/04
21:08:07 [notice] 7135#0
: signal process started
2015/01/11
20:59:24 [notice] 5201#0: signal process started

3. 列印當天22:13:53以後的日誌

shell> gawk -f '''

}' /usr/local/nginx/logs/error.log 
2015/01/03
22:15:54 [notice] 31090#0
: signal process started
2015/01/03
22:15:54 [error] 31090#0: open() "
/usr/local/nginx/logs/nginx.pid
" failed (2: no such file
or directory)
2015/01/03
22:19:51 [notice] 32601#0
: signal process started
2015/01/03
22:19:51 [error] 32601#0: open() "
/usr/local/nginx/logs/nginx.pid
" failed (2: no such file
or directory)
2015/01/03
23:01:51 [notice] 4960#0: signal process started

4. 列印5分鐘內的日誌

shell> gawk -f '''

}' /usr/local/nginx/logs/error.log 
2015/01/03
22:15:54 [notice] 31090#0
: signal process started
2015/01/03
22:15:54 [error] 31090#0: open() "
/usr/local/nginx/logs/nginx.pid
" failed (2: no such file or directory)

5. 每天定時切割nginx日誌指令碼

#!/bin/bash

# this script run at 
00:00
# the nginx logs path
logs_path="
/usr/local/webserver/nginx/logs/
"mkdir -p $$(date -d "
yesterday
" +"
%y")/$(date -d "
yesterday
" +"
%m")/
mv $access.log $$(date -d "
yesterday
" +"
%y")/$(date -d "
yesterday
" +"
%m")/access_$(date -d "
yesterday
" +"
%y%m%d
").log
kill -usr1 `cat /usr/local/webserver/nginx/nginx.pid`
設定crontab，每天凌晨00:00切割nginx訪問日誌
crontab -e
輸入以下內容：

MYSQL日誌檔案維護

在 mysql伺服器啟動時，它檢查其命令列的操作，來檢視它是否應該執行登入並開啟相應的日誌檔案 如果應該的話 可以讓伺服器生成兩種主要型別的日誌檔案 常規日誌檔案。它報告客戶機的連線 查詢和其他各種各樣的事件。它對於跟蹤伺服器的活動很有用 誰正在連線 從 連線，以及他們正在做什麼。更新日誌。它報告修...
