【转】mac os 安装php

安装PHP

添加brew的PHP扩展库：

brew update
brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php

可以使用brew options php55命令来查看安装php5.5的选项，这里我用下面的选项安装：

brew install php55 --with-fpm --with-gmp --with-imap --with-tidy --with-debug --with-mysql --with-libmysql

PHP编译过程中如果遇到configure: error: Cannot find OpenSSL's <evp.h>错误，执行xcode-select --install 重新安装一下Xcode Command Line Tools 在GitHub HomeBrew上有关于这个讨论:
For future reference of anybody looking for Command Line Tools with Xcode 5, open up a Terminal window and type xcode-select --install. A window will appear informing you command line tools are required. Click Install and you should be good to go

等待PHP编译完成，开始安装PHP常用扩展，扩展安装过程中brew会自动安装依赖包，例如php55-pdo-pgsql 会自动装上postgresql,这里我安装以下PHP扩展：

brew install php55-apcu
 php55-gearman
 php55-geoip
 php55-gmagick
 php55-imagick
 php55-intl
 php55-mcrypt
 php55-memcache
 php55-memcached
 php55-mongo
 php55-opcache
 php55-pdo-pgsql
 php55-phalcon
 php55-redis
 php55-sphinx
 php55-swoole
 php55-uuid
 php55-xdebug;

扩展里面提一下php55-phalcon 和 php55-swoole. 一个是C语言写的PHP框架，安装来个人摸索熟悉一下，还没有真正的使用过，大致看了一下文档，感觉非常吊炸天。目前公司的项目是基于Yii2的，也看看这个框架。 另外一个swoole是国产的PHP高性能网络通信框架，貌似不错，可能在项目中会考虑用到它。

由于Mac自带了php和php-fpm，因此需要添加系统环境变量PATH来替代自带PHP版本。

echo 'export PATH="$(brew --prefix php55)/bin:$PATH"' >> ~/.bash_profile  #for php
echo 'export PATH="$(brew --prefix php55)/sbin:$PATH"' >> ~/.bash_profile  #for php-fpm
echo 'export PATH="/usr/local/bin:/usr/local/sbib:$PATH"' >> ~/.bash_profile #for other brew install soft
source ~/.bash_profile

测试一下效果：

#brew安装的php 他在/usr/local/opt/php55/bin/php
php -v

php-fpm -v

修改php-fpm配置文件，vim /usr/local/etc/php/5.5/php-fpm.conf，找到pid相关大概在25行，去掉注释 pid = run/php-fpm.pid, 那么php-fpm的pid文件就会自动产生在/usr/local/var/run/php-fpm.pid，下面要安装的Nginx pid文件也放在这里。

#测试php-fpm配置
php-fpm -t
php-fpm -c /usr/local/etc/php/5.5/php.ini -y /usr/local/etc/php/5.5/php-fpm.conf -t

#启动php-fpm
php-fpm -D
php-fpm -c /usr/local/etc/php/5.5/php.ini -y /usr/local/etc/php/5.5/php-fpm.conf -D

#关闭php-fpm
kill -INT `cat /usr/local/var/run/php-fpm.pid`

#重启php-fpm
kill -USR2 `cat /usr/local/var/run/php-fpm.pid`

#也可以用上文提到的brew命令来重启php-fpm，不过他官方不推荐用这个命令了
brew services restart php55

#还可以用这个命令来启动php-fpm
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist

启动php-fpm之后，确保它正常运行监听9000端口：

lsof -Pni4 | grep LISTEN | grep php
php-fpm   30907 calvin    9u  IPv4 0xf11f9e8e8033a2a7      0t0  TCP 127.0.0.1:9000 (LISTEN)
php-fpm   30917 calvin    0u  IPv4 0xf11f9e8e8033a2a7      0t0  TCP 127.0.0.1:9000 (LISTEN)
php-fpm   30918 calvin    0u  IPv4 0xf11f9e8e8033a2a7      0t0  TCP 127.0.0.1:9000 (LISTEN)
php-fpm   30919 calvin    0u  IPv4 0xf11f9e8e8033a2a7      0t0  TCP 127.0.0.1:9000 (LISTEN)

#正常情况，会看到上面这些进程

PHP-FPM开机启动：

ln -sfv /usr/local/opt/php55/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php55.plist

安装php composer

brew install composer
#检查一下情况
composer --version
Composer version 1.0.0-alpha8 2014-01-06 18:39:59

redis memcached这些软件brew 已经自动依赖安装上，如果想开机自动启动，或者查看使用说明 brew info redis即可。另外，composer的中文文档：猛戳这里
