linux - 怎樣讓 php 在 cli 與 fpm 環境下運行時載入不同的擴充 ?

問題:

由於開啟了 xdebug 擴充, 導致使用 composer 時提示:

You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug

所以想在 cli 下不再載入 xdebug

環境:

• linux 為 archlinux

• php 通過 pacman 安裝, 版本 7.0.1

• web服務通過 php-fpm 運行

設定檔分布:

/etc/php├── conf.d│   └── xdebug.ini├── fpm.d├── pear.conf├── php-fpm.conf├── php-fpm.d│   └── www.conf├── php.ini└── php.ini.pacnew

對比 ubuntu 下 通過 apt 安裝的 php 設定檔分布:

/etc/php5/├── cli│   ├── conf.d│   └── php.ini├── fpm│   ├── conf.d│   │   ├── 20-xdebug.ini -> ../../mods-available/xdebug.ini│   ├── php-fpm.conf│   ├── php.ini│   └── pool.d│       └── www.conf└── mods-available    └── xdebug.ini

• https://projects.archlinux.org/svntogit/packages.git/tree/trunk/PKGBUILD?h=packages/php

在不自行編譯安裝,重新指定各項config參數的情況下, 也只好手動指定 php.ini 運行了

使用兩個不同的 php.ini 設定檔配置不同的運行參數（包括擴充參數），在開啟 cli 或者 fpm 時，通過 -c 參數指定運行所使用的 php.ini 即可。

PHP和PHP-FPM都可以用參數-c指定php.ini設定檔.

執行下列命令可見:

strace -f -o strace.log \/png/php/5.4.45/bin/php -v && \cat strace.log|egrep 'open|read'|grep 'ini'3080  open("/png/php/5.4.45/bin/php-cli.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3080  open("/png/php/5.4.45/lib/php-cli.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3080  open("/png/php/5.4.45/bin/php.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3080  open("/png/php/5.4.45/lib/php.ini", O_RDONLY) = 3

PHP會優先讀取php程式所在目錄下的php-cli.ini,訪問到則不再讀取其他ini檔案.
PHP-FPM情況如下:

strace -f -o strace.log \/png/php/5.4.45/sbin/php-fpm -v && \cat strace.log|egrep 'open|read'|grep 'ini'3537  open("/png/php/5.4.45/lib/php-fpm-fcgi.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3537  open("/png/php/5.4.45/lib/php.ini", O_RDONLY) = 3

PHP-CGI情況如下:

strace -f -o strace.log \/png/php/5.4.45/bin/php-cgi -v && \cat strace.log|egrep 'open|read'|grep 'ini'3568  open("./php-cgi-fcgi.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3568  open("/png/php/5.4.45/bin/php-cgi-fcgi.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3568  open("/png/php/5.4.45/lib/php-cgi-fcgi.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3568  open("./php.ini", O_RDONLY)       = -1 ENOENT (No such file or directory)3568  open("/png/php/5.4.45/bin/php.ini", O_RDONLY) = -1 ENOENT (No such file or directory)3568  open("/png/php/5.4.45/lib/php.ini", O_RDONLY) = 3

可以把cli目錄下的conf.d 的20-xdebug.ini 設定為禁用應該就可以了
