2、下载Windows Service Wrapper官网地址：https://github.com/kohsuke/winsw/下载地址：http://repo.jenkins-ci.org/releases/com/sun/winsw/winsw/

3、解压PHP压缩包文件到C盘根目录，并且重命名为php

4、将"winsw-1.19-bin.exe"重命名为"php-service.exe",并且复制到PHP根目录

5、在PHP根目录编写php-service.xml文件

php-service.xml文件内容

<?xml version="1.0" encoding="UTF-8" ?><service> <id>PHP</id> <name>PHP</name> <description>本服务用于加载PHP服务，请确保开机启动。</description> <logpath>C:phplogs</logpath> <executable>php-cgi.exe</executable> <arguments>-b 127.0.0.1:9000 -c php.ini</arguments> <logmode>rotate</logmode></service>

6、创建服务日志目录

在PHP根目录创建网站目录，命名为"logs"。

7、配置PHP配置PHP环境变量按下Win+X+Y键进入Win系统界面点击"高级系统设置"—>"高级"—>"环境变量"

在环境变量中，设置三个属性，分别为：

PHP_HOME,Path

(大小写无所谓),若已存在则点击"编辑"，不存在则点击"新建"。

a、设置PHP_HOME

变量名：PHP_HOME

变量值：C:php（PHP安装路径）

b、设置Path

变量名：Path

变量值：%PHP_HOME%

环境变量配置完成之后测试是否成功

按下Win+X+C键

打开命令提示符

输入：php -v

看到如下图，说明已经配置成功了。

8、安装PHP系统服务或者卸载PHP系统服务8.1、安装PHP系统服务按下Win+X+A键打开命令提示符（管理员）输入：C:phpphp-service.exe install

8.2、卸载PHP系统服务按下Win+X+A键打开命令提示符（管理员）输入：C:phpphp-service.exe uninstall

9、查看系统服务9.1、进入服务

运行Win+R输入:

9.2、PHP系统服务属性

10、编辑PHP配置文件

PHP配置文件目录：

C:php

10.1、将"php.ini-production"文件重命名为"php.ini"。

10.2、编辑PHP配置文件php.ini

[PHP] ;;;;;;;;;;;;;;;;;;;; About php.ini  ;;;;;;;;;;;;;;;;;;;;; PHP"s initialization file, generally called php.ini, is responsible for; configuring many of the aspects of PHP"s behavior. ; PHP attempts to find and load this configuration from a number of locations.; The following is a summary of its search order:; 1. SAPI module specific location.; 2. The PHPRC environment variable. (As of PHP 5.2.0); 3. A number of predefined registry keys on Windows (As of PHP 5.2.0); 4. Current working directory (except CLI); 5. The web server"s directory (for SAPI modules), or directory of PHP; (otherwise in Windows); 6. The directory from the --with-config-file-path compile time option, or the; Windows directory (C:windows or C:winnt); See the PHP docs for more specific information.; [url=http://php.net/configuration.file]http://php.net/configuration.file[/url] ; 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 following the section heading [PATH=/www/mysite] only; apply to PHP files in the /www/mysite directory. Directives; following the section heading [HOST=www.example.com] only apply to; PHP files served from [url=http://www.example.com.]www.example.com.[/url] Directives set in these; special sections cannot be overridden by user-defined INI files or; at runtime. Currently, [PATH=] and [HOST=] sections only work under; CGI/FastCGI.; [url=http://php.net/ini.sections]http://php.net/ini.sections[/url] ; Directives are specified using the following syntax:; directive = value; Directive names are *case sensitive* - foo=bar is different from FOO=bar.; Directives are variables used to configure PHP or PHP extensions.; There is no name validation. If PHP can"t find an expected; directive because it is not set or is mistyped, a default value will be used. ; 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), a quoted string ("bar"), or a reference to a; previously set variable or directive (e.g. ${foo}) ; Expressions in the INI file are limited to bitwise operators and parentheses:; | bitwise OR; ^ bitwise XOR; & 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 ;;;;;;;;;;;;;;;;;;;;; PHP comes packaged with two INI files. One that is recommended to be used; in production environments and one that is recommended to be used in; development environments. ; php.ini-production contains settings which hold security, performance and; best practices at its core. But please be aware, these settings may break; compatibility with older or less security conscience applications. We; recommending using the production ini in production and testing environments. ; php.ini-development is very similar to its production variant, except it is; much more verbose when it comes to errors. We recommend using the; development version only in development environments, as errors shown to; application users can inadvertently leak otherwise secure information. ; This is php.ini-production INI file. ;;;;;;;;;;;;;;;;;;;; Quick Reference ;;;;;;;;;;;;;;;;;;;;; The following are all the settings which are different in either the production; or development versions of the INIs with respect to PHP"s default behavior.; Please see the actual settings later in the document for more details as to why; we recommend these changes in PHP"s behavior. ; display_errors;  Default Value: On;  Development Value: On;  Production Value: Off ; display_startup_errors;  Default Value: Off;  Development Value: On;  Production Value: Off ; error_reporting;  Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED;  Development Value: E_ALL;  Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT ; html_errors;  Default Value: On;  Development Value: On;  Production value: On ; log_errors;  Default Value: Off;  Development Value: On;  Production Value: On ; max_input_time;  Default Value: -1 (Unlimited);  Development Value: 60 (60 seconds);  Production Value: 60 (60 seconds) ; output_buffering;  Default Value: Off;  Development Value: 4096;  Production Value: 4096 ; register_argc_argv;  Default Value: On;  Development Value: Off;  Production Value: Off ; request_order;  Default Value: None;  Development Value: "GP";  Production Value: "GP" ; session.gc_divisor;  Default Value: 100;  Development Value: 1000;  Production Value: 1000 ; session.hash_bits_per_character;  Default Value: 4;  Development Value: 5;  Production Value: 5 ;开启短标签short_open_tagDefault Value: OnDevelopment Value: OffProduction Value: Off ; track_errors;  Default Value: Off;  Development Value: On;  Production Value: Off ; url_rewriter.tags;  Default Value: "a=href,area=href,frame=src,form=,fieldset=";  Development Value: "a=href,area=href,frame=src,input=src,form=fakeentry";  Production Value: "a=href,area=href,frame=src,input=src,form=fakeentry" ; variables_order;  Default Value: "EGPCS";  Development Value: "GPCS";  Production Value: "GPCS" ;;;;;;;;;;;;;;;;;;;;; php.ini Options ;;;;;;;;;;;;;;;;;;;;;; Name for user-defined php.ini (.htaccess) files.

If your application"s output exceeds this setting, PHP; will send that data in chunks of roughly the size you specify.; Turning on this setting and managing its maximum buffer size can yield some; interesting side-effects depending on your application and web server.; You may be able to send headers and cookies after you"ve already sent output; through print or echo. You also may see performance benefits if your server is; emitting less packets due to buffered output versus PHP streaming the output; as it gets it. On production servers, 4096 bytes is a good setting for performance; reasons.; Note: Output buffering can also be controlled via Output Buffering Control;  functions.; Possible Values:;  On = Enabled and buffer is unlimited. (Use with caution);  Off = Disabled;  Integer = Enables the buffer and sets its maximum size in bytes.; Note: This directive is hardcoded to Off for the CLI SAPI; Default Value: Off; Development Value: 4096; Production Value: 4096; [url=http://php.net/output-buffering]http://php.net/output-buffering[/url]output_buffering = 4096 ; 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.; [url=http://php.net/output-handler]http://php.net/output-handler[/url];output_handler = ; Transparent output compression using the zlib library; Valid values for this option are "off", "on", or a specific buffer size; to be used for compression (default is 4KB); Note: Resulting chunk size may vary due to nature of compression. PHP;  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.; Note: You need to use zlib.output_handler instead of the standard;  output_handler, or otherwise the output will be corrupted.; [url=http://php.net/zlib.output-compression]http://php.net/zlib.output-compression[/url]zlib.output_compression = Off ; [url=http://php.net/zlib.output-compression-level]http://php.net/zlib.output-compression-level[/url];zlib.output_compression_level = -1 ; You cannot specify additional output handlers if zlib.output_compression; is activated here.

The recommended way of setting values for this; directive is through the use of the error level constants and bitwise; operators. The error level constants are below here for convenience as well as; some common settings and their meanings.; By default, PHP is set to take action on all errors, notices and warnings EXCEPT; those related to E_NOTICE and E_STRICT, which together cover best practices and; recommended coding standards in PHP. For performance reasons, this is the; recommend error reporting setting. Your production server shouldn"t be wasting; resources complaining about best practices and coding standards. That"s what; development servers and development settings are for.; Note: The php.ini-development file has this setting as E_ALL. This; means it pretty much reports everything which is exactly what you want during; development and early testing.;; Error Level Constants:; E_ALL       - All errors and warnings (includes E_STRICT as of PHP 5.4.0); E_ERROR      - fatal run-time errors; E_RECOVERABLE_ERROR - almost fatal run-time errors; E_WARNING     - run-time warnings (non-fatal errors); E_PARSE      - compile-time parse errors; E_NOTICE     - run-time notices (these are warnings which often result;           from a bug in your code, but it"s possible that it was;           intentional (e.g., using an uninitialized variable and;           relying on the fact it is automatically initialized to an;           empty string); E_STRICT     - run-time notices, enable to have PHP suggest changes;           to your code which will ensure the best interoperability;           and forward compatibility of your code; E_CORE_ERROR   - fatal errors that occur during PHP"s initial startup; E_CORE_WARNING  - warnings (non-fatal errors) that occur during PHP"s;           initial startup; E_COMPILE_ERROR  - fatal compile-time errors; E_COMPILE_WARNING - compile-time warnings (non-fatal errors); E_USER_ERROR   - user-generated error message; E_USER_WARNING  - user-generated warning message; E_USER_NOTICE   - user-generated notice message; E_DEPRECATED   - warn about code that will not work in future versions;           of PHP; E_USER_DEPRECATED - user-generated deprecation warnings;; Common Values:;  E_ALL (Show all errors, warnings and notices including coding standards.);  E_ALL & ~E_NOTICE (Show all errors, except for notices);  E_ALL & ~E_NOTICE & ~E_STRICT (Show all errors, except for notices and coding standards warnings.);  E_COMPILE_ERROR|E_RECOVERABLE_ERROR|E_ERROR|E_CORE_ERROR (Show only errors); Default Value: E_ALL & ~E_NOTICE & ~E_STRICT & ~E_DEPRECATED; Development Value: E_ALL; Production Value: E_ALL & ~E_DEPRECATED & ~E_STRICT; [url=http://php.net/error-reporting]http://php.net/error-reporting[/url];消除警告error_reporting = E_ALL & ~E_NOTICE ; This directive controls whether or not and where PHP will output errors,; notices and warnings too. Error output is very useful during development, but; it could be very dangerous in production environments. Depending on the code; which is triggering the error, sensitive information could potentially leak; out of your application such as database usernames and passwords or worse.; For production environments, we recommend logging errors rather than; sending them to STDOUT.; Possible Values:;  Off = Do not display any errors;  stderr = Display errors to STDERR (affects only CGI/CLI binaries!);  On or stdout = Display errors to STDOUT; Default Value: On; Development Value: On; Production Value: Off; [url=http://php.net/display-errors]http://php.net/display-errors[/url]display_errors = Off ; The display of errors which occur during PHP"s startup sequence are handled; separately from display_errors. PHP"s default behavior is to suppress those; errors from clients. Turning the display of startup errors on can be useful in; debugging configuration problems.
