linux - 怎样让 php 在 cli 与 fpm 环境下运行时加载不同的扩展 ?

Jun 06, 2016 pm 08:20 PM
linux php

问题:

由于开启了 xdebug 扩展, 导致使用 composer 时提示:

<code>You are running composer with xdebug enabled. This has a major impact on runtime performance. See https://getcomposer.org/xdebug
</code>
Copy after login
Copy after login

所以想在 cli 下不再加载 xdebug

环境:

  • linux 为 archlinux

  • php 通过 pacman 安装, 版本 7.0.1

  • web服务通过 php-fpm 运行

配置文件分布:

<code>/etc/php
├── conf.d
│   └── xdebug.ini
├── fpm.d
├── pear.conf
├── php-fpm.conf
├── php-fpm.d
│   └── www.conf
├── php.ini
└── php.ini.pacnew
</code>
Copy after login
Copy after login

对比 ubuntu 下 通过 apt 安装的 php 配置文件分布:

<code>/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
</code>
Copy after login

---update ---

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

不自行编译安装,重新指定各项config参数的情况下, 也只好手动指定 php.ini 运行了

不自行编译安装,重新指定各项config参数的情况下, 也只好手动指定 php.ini 运行了

使用两个不同的 php.ini 配置文件配置不同的运行参数(包括扩展参数),在开启 cli 或者 fpm 时,通过 -c 参数指定运行所使用的 php.ini 即可。

PHP和PHP-FPM都可以用参数-c指定php.ini配置文件.

执行下列命令可见:

<code>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
</code>
Copy after login

PHP会优先读取php程序所在目录下的php-cli.ini,访问到则不再读取其他ini文件.
PHP-FPM情况如下:

<code>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
</code>
Copy after login

PHP-CGI情况如下:

<code>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
</code>
Copy after login

可以把cli目录下的conf.d 的20-xdebug.ini 设置为禁用应该就可以了

How to run java code in notepad How to run java code in notepad Apr 16, 2025 pm 07:39 PM

Although Notepad cannot run Java code directly, it can be achieved by using other tools: using the command line compiler (javac) to generate a bytecode file (filename.class). Use the Java interpreter (java) to interpret bytecode, execute the code, and output the result.
