问题:
由于开启了 xdebug 扩展, 导致使用 composer 时提示:
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
立即学习“PHP免费学习笔记（深入）”；
配置文件分布:
/etc/php ├── conf.d │ └── xdebug.ini ├── fpm.d ├── pear.conf ├── php-fpm.conf ├── php-fpm.d │ └── www.conf ├── php.ini └── php.ini.pacnew
对比 ubuntu 下 通过 apt 安装的 php 配置文件分布:
/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

在不自行编译安装,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:
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:
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情况如下:
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目录下的conf.d 的20-xdebug.ini 设置为禁用应该就可以了
