Ⅰ 如何將windows日誌轉成syslog格式

本篇文章是對php中將日誌寫進syslog的方法進行了詳細的分析介紹，需要的朋友參考下 在做項目的時候們為了方便運維，我們經常需要將系統日誌寫入系統syslog，下邊我們就介紹一下，在linux下php對syslog的操作： 在linux中配置syslog 在linux中，facility(設備)有以下幾種： AUTH 普通安全/授權消息 AUTHPRIV 私有安全/授權消息 CRON 定時器進程 DAEMON 守護進程 KERN 內核消息 LOCAL0 ... LOCAL7 本地應用，在windows上不支持 LPR 行式列印機 MAIL 郵件服務 NEWS 新聞服務 SYSLOG 由syslogd內部產生的消息 USER 通用的用戶級信息 UUCP UUCP子系統 登錄linux系統，進入/etc目錄，輸入： 復制代碼 代碼如下: vim syslog.conf 打開syslog的配置文件 在這里，你可以看到syslog的所有配置信息，這里定義了在上一節中提到的每種日誌類型存儲日誌所使用的條件，如： daemon.* -/var/log/daemon.log 定義了daemon所產生的日誌的保存位置，其中daemon為日誌類型，“*”代表將所有級別的日誌都放到該文件。格式為： facility。level -日誌文件保存的路徑，如-/var/log/daemon.log level包括: emerg －該系統不可用 alert －需要立即被修改的條件 crit －阻止某些工具或子系統功能實現的錯誤條件 err －阻止工具或某些子系統部分功能實現的錯誤條件 warning －預警信息 notice －具有重要性的普通條件 info －提供信息的消息 debug －不包含函數條件或問題的其他信息 none －沒有重要級，通常用於排錯 * 所有級別，除了none 下面我們在配置文件中定義一個自己設備的日誌規則：local4.info -/var/log/ 接下來執行命令/etc/init.d/sysklogd restart或/etc/init.d/sysklogd reload使新增的配置生效，下面我們可以測試新增的日誌規則了： 1.輸入命令 logger -p local4.info " my test log" 2.執行命令 tail /var/log/event_log.log 你可以看到自己寫入的日誌信息： 注意：syslog.conf中local4.info 代表所有info級別以及以上的日誌會記錄到這里 ok，到現在我們已經在ubuntu中設置好了我們需要的日誌，下面我們用php中的syslog將日誌寫到ubuntu中的syslog中。 下面直接上php代碼： 復制代碼 代碼如下: openlog("Event1.0", LOG_PID LOG_PERROR, LOG_LOCAL4); syslog($level, "LOG MESSAGE: " . $errinfo); closelog(); 以上各方法的具體用法請查看PHP的API，具體用法不在這里贅述。 其中openlog的第一個參數，是日誌標識，該標識會自動加在日誌信息的開始，用來表示是什麼系統寫入的日誌。 由於我們想要將日誌寫入local4.info，所以第三個參數需使用LOG_LOCAL4，該參數表示寫入日誌的設備信息。 syslog中$level為日誌級別，包括： LOG_EMERG system is unusable LOG_ALERT action must be taken immediately LOG_CRIT critical conditions LOG_ERR error conditions LOG_WARNING warning conditions LOG_NOTICE normal, but significant, condition LOG_INFO informational message LOG_DEBUG debug-level message 第二個參數為具體的日誌內容。

Ⅱ 6.如何禁止php服務程序中不安全的功能

為了使php程序更安全，很多站長都選擇了禁用一些比較敏感的函數，那影響php安全的函數到底有哪些呢，下面我們列出了一些：
1、phpinfo()

Ⅲ 如何在windows 2008 server r2中配置php程序

如何在windows 2008 server r2中配置php程序
一、准備工作

1、所需軟體：
Mysql資料庫：本文用MySQL-essential-5.0.45-win32.msi PHP : 本文用php-5.2.4-Win32.zip
ZendOptimizer ：本文用ZendOptimizer-3.3.0-Windows-i386.exe 將上述軟體網上搜索下載後置於同一目錄中，比如：webtools(下文舉例同)

2、安裝IIS 7，簡要步驟如下：
(1)在控制面板中，選擇程序-打開關閉Windows功能;
(2)在彈出的Windows功能中選中Internet信息服務;
(3)展開-萬維網服務-應用程序開發功能，選中ISAPI擴展(重要);
(4)確定後自動安裝;
(5)在IE地址欄里輸入http://127.0.0.1(你的IP地址)，即可看到IIS7的歡迎界面(圖1)

二、PHP環境部署攻略
MySQL資料庫部署
(1) 安裝MySQL資料庫
進入 X:Webtools 目錄點擊MySQL-essential-5.0.45-win32.msi開始安裝，
選擇 Custom 定製安裝，
選擇"Change"更改MySQL 安裝位置，
文件復制完畢後，進入 MySQL 設置界面，單擊 Finish(完成) ，
選擇 Detailed Configuration (詳細配置)，
選擇 MySQL 運行模式，在此處，我們選擇Server Machine
選擇 MySQL 資料庫默認存儲方式-Non-Trans Only
設置最大連接數：這里我們選擇 128 - 512 之間的整數即可。
此處設置 MySQL 網路參數,Strict Mode不要選擇,
設置默認字元集：這里我們選擇了GBK模式，需要按照自己的需要選擇即可，
Windows
服務模式設定
修改設定 root 用戶密碼(remote machines不要啟動)
MySQL
安裝完成，
(2) 測試 MySQL資料庫。

在命令行模式下(開始-運行-CMD)輸入：

MySQL –u
root –p
按照提示輸入密碼後，如能進入 MySQL 控制台則說明 MySQL 安裝正常，否則需要檢查先前安裝步驟和相應服務是否啟動，進行重新安裝。
(3) 更改 MySQL 資料庫目錄
1)打開 cmd 命令提示符窗口，輸入命令：
net stopMySQL
停止 MySQL 服務運行;
2) 打開X:WebMySQLmy.ini
找到：
Datadir ="X:WebMySQLdata"
修改為：
Datadir ="X:Database"
3) 將 X:WebMySQLdata 目錄復制到 X: ，並重命名為X:Database;
4) 打開 cmd 命令提示符窗口，輸入命令：net startMySQL 啟動 MySQL 服務，重新測試 MySQL 是否工作正常。
5)准備 LibMySQL 動態鏈接庫
將X:WebMySQLbinlibMySQL.dll 文件復制到C:WindowsSystem32 即可。

2. PHP服務部署
(1) 解壓縮php-5.2.4-Win32.zip文件並將其復制到：X:WebPHP目錄、將 php.ini-dist 重命名為 php.ini ;
(2) 打開 php.ini 文件，找到：extension_dir= "./"
將其改為;
extension_dir= "X:WebPHPext"
(3) 找到：Windows Extensions ：(去掉模塊配置每行前面的;號即可)
extension=php_mbstring.dll
extension=php_gd2.dll
extension=php_MySQL.dll
(5) 找到：
disable_functions =
改為：
disable_functions =phpinfo,passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_open,proc_get_status,ini_alter,ini_alter,ini_restore,dl,pfsockopen,
openlog,syslog,readlink,symlink,popepassthru,stream_socket_server
保存 php.ini 文件，並將其復制到 C:Windows 目錄。

3. IIS 7整合PHP-新建站點
(1) 啟動 IIS 管理器，選擇新建-網站，
(2) 輸入網站名稱，可任意輸入。網站IP地址不用填寫，埠如沒有特殊要求則保持 80 即可，最後正確輸入網站域名。
(3) 在網站分區中建立 wwwroot 以及下級站點目錄。
(4)給予該站點"讀取"和"運行腳本"的許可權以便PHP應用。

4. IIS整合 PHP- 使站點支持 PHP
(1) 打開剛剛建立的網站屬性，
(2) 在站點屬性窗口中，單擊"主目錄"頁簽，單擊"配置"按鈕，在新彈出的"應用程序配置"對話框中，單擊"添加"按鈕，加入 PHP 的 ISAPI 支持，選擇可執行文件：X:WebPHPphp5isapi.dll 、擴展名為 .php 、限制動作為：GET,POST 。單擊"確定"添加，並在"應用程序配置"窗口中查看 .php 擴展是否載入成功。若成功，則單擊"確定"關閉配置窗口，回到站點屬性主窗口。
(3) 單擊"文檔"頁簽，在默認內容文檔中添加 index.htm、index.html、index.php 三個文件。
(4)
右鍵單擊"Web 服務擴展"，添加 PHP 擴展支持。
(5) 在如下圖的"新建WEB服務擴展"對話框中，"擴展名"填寫PHP，"文件"選擇 X:WebPHPphp5isapi.dll ，並設置該PHP擴展默認為允許。
(6) 重啟 IIS 服務，

5、測試 PHP
IIS與PHP的整合已經完畢，下面需要測試 PHP 支持是否正常。
(1) 進入 X:wwwrootbbs 目錄，新建一個 phpinfo.php 文件，內容為：
<?
phpinfo();
?>
(2) 打開IE瀏覽器，輸入：http://127.0.0.1/phpinfo.php ;
(3) 如果能夠正常顯示PHP支持信息則表明配置整合是成功的。
至此，IIS 7下PHP環境部署基本完成，不過，還有一個重要的軟體需要安裝，即 Zend Optimizer 的安裝。 Zend Optimzer 的安裝沒有特別之處，按照提示安裝即可。整個伺服器的PHP環境配置完畢。

Ⅳ 請問php中syslog()函數怎麼用呢最好可以詳細說明，非常感謝！

就是把自定義的信息寫入到主機所在的系統日誌。

對於windows系統就是寫入到eventlog。

語法

bool syslog ( int $priority , string $message )

priority 是預定義好的枚舉，用int表示，可以是以下值

值 意義

LOG_EMERG system is unusable

LOG_ALERT action must be taken immediately

LOG_CRIT critical conditions

LOG_ERR error conditions

LOG_WARNING warning conditions

LOG_NOTICE normal, but significant, condition

LOG_INFO informational message

LOG_DEBUG debug-level message

message 是自定義消息，可以保存在日誌中。

調用該函數成功返回true,否則返回false

範例，linux平台

<?php
//先使用openlog打開日誌服務進程需要指定log服務的pid
//win系統，無法使用log_local0參數。這個參數可以省略
//linux系統可以指定log_local0~log_local7看你需求
openlog("myScriptLog",LOG_PID|LOG_PERROR,LOG_LOCAL0);
//somecode
if(authorized_client()){
//一些代碼過程
}else{
//
//嘗試記錄日誌
$access=date("Y/m/dH:i:s");
syslog(LOG_WARNING,"Unauthorizedclient:$access{$_SERVER['REMOTE_ADDR']}({$_SERVER['HTTP_USER_AGENT']})");
}
closelog();//關閉日誌服務的調用
?>

Ⅳ php安裝的問題，無法載入 mysql 擴展，請檢查 PHP 配置

首先你需要將PHP安裝目錄下的php_mysql.dll和php_mysqli.dll（我的在D:\apptools\php5\ext目錄下）復制到c:\windows\system32目錄下，然後修改php.ini文件（需要放到c:\windows目錄下），關鍵是extension=php_mysql.dll 和extension_dir = "D:/apptools/php5/ext"。
我的配置是這樣的：

[PHP]

;;;;;;;;;;;
; WARNING ;
;;;;;;;;;;;
; This is the default settings file for new PHP installations.
; By default, PHP installs itself with a configuration suitable for
; development purposes, and *NOT* for proction purposes.
; For several security-oriented considerations that should be taken
; before going online with your site, please consult php.ini-recommended
; and http://php.net/manual/en/security.php.

;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior. In order for PHP to
; read it, it must be named 'php.ini'. PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory. The
; path in which the php.ini file is looked for can be overridden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple. Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
; foo = ; sets foo to an empty string
; foo = none ; sets foo to an empty string
; foo = "none" ; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
;
;
;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

; be supported on the target server. For portable, redistributable code,
; be sure not to use short tags.

; Output buffering allows you to send header lines (including cookies) even
; after you send body content, at the price of slowing PHP's output layer a
; bit. You can enable output buffering ring runtime by calling the output
; buffering functions. You can also enable output buffering for all files by
; setting this directive to On. If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).
output_buffering = On

; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to "mb_output_handler", character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
; is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
; and you cannot use both "ob_gzhandler" and "zlib.output_compression".
; Note: output_handler must be empty if this is set 'On' !!!!
; Instead you must use zlib.output_handler.
;output_handler =

; Transparent output compression using the zlib library

; outputs chunks that are few hundreds bytes each as a result of
; compression. If you prefer a larger chunk size for better
; performance, enable output_buffering in addition.

Ⅵ php-fpm錯誤日誌不能記錄怎麼辦

要想讓php-fpm顯示錯誤日誌，首先需要配置php-fpm。
在php-fpm的配置文件中（一般位於php安裝目錄下的etc/php-fpm.conf）配置php錯誤日誌的文件路徑。

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /home/wangwei/php/var
; Default Value: log/php-fpm.log
;error_log = log/php-fpm.log

如上是我的php-fpm.conf文件中配置錯誤日誌的地方。把error_log = log/php-fpm.log之前的;去掉，然後修改為：

; Error log file
; If it's set to "syslog", log is sent to syslogd instead of being written
; in a local file.
; Note: the default prefix is /home/wangwei/php/var
; Default Value: log/php-fpm.log
error_log = /home/work/log/php-fpm.log.wf

修改之後，保存配置，然後重啟php-fpm就可以啦。
注意如果用相對路徑的話，的路徑的前綴是基於php安裝目錄的var目錄的。

Ⅶ php 怎麼獲取 linux磁碟讀寫io使用率

1.使用iotop命令

使用該命令有個條件，Linux內核要高於2.6.20的版本，版本過低則沒有此命令，執行效果如下圖所示：

2：block_mp方法

首先，關閉syslog服務，然後開啟block_mp，最後正則表達式提取dmesg信息。
/etc/init.d/syslog stop
echo 1 > /proc/sys/vm/block_mp
dmesg | egrep "READ|WRITE|dirtied" | egrep -o '([a-zA-Z]*)' | sort | uniq -c | sort -rn | head
執行結果如下圖所示：

注意：操作完成後請關閉block_mp和啟動syslog
echo 0 > /proc/sys/vm/block_mp #關閉block_mp
/etc/init.d/syslog start #啟動syslog

Ⅷ php openlog()函數怎麼用最好能詳細說明，非常感謝！

本函數會打開操作系統的紀錄機制 (logger)。參數 ident 會加到紀錄的字元串中。參數 option 的值包括了 LOG_PID、LOG_CONS、LOG_ODELAY、LOG_NDELAY、LOG_NOWAIT、LOG_PERROR，在 Win32 系統中，只有 LOG_PID 有效。參數 facility 的值可能為 LOG_KERN、LOG_USER、LOG_MAIL、LOG_DAEMON、LOG_AUTH、LOG_SYSLOG、LOG_LPR、LOG_NEWS、LOG_UUCP、LOG_CRON 或 LOG_AUTHPRIV，在 Win32 系統上，本參數是無效的欄位。本函數呼叫 UNIX 系統的 openlog() 函數，因此在 Windows 系列的操作系統中，本函數沒有完全的實作。

使用範例
<?php
openlog("FUN", LOG_PID | LOG_CONS, LOG_USER);
syslog(LOG_INFO, "Wa ha ha ....");
closelog();
?>

參考
syslog() closelog()
