苹果下面安装php5.4还算是比较方便的，主要是默认为php5.3，想用trait的时候，没5.4跑不了啊。。
于是直接使用brew install php54，结果报错，查了下资料，原来，需要：
- brew tap josegonzalez/homebrew-php
- brew tap homebrew/dupes
- brew install php54 --with-mysql --with-intl --with-fpm --without-apache
因为有装nginx。所以就without-apache了。。。
安装好后，brew 会告诉你：
XML/HTML代码
- The php.ini file can be found in:
- /usr/local/etc/php/5.4/php.ini
- ✩✩✩✩ PEAR ✩✩✩✩
- If PEAR complains about permissions, 'fix' the default PEAR permissions and config:
- chmod -R ug+w /usr/local/Cellar/php54/5.4.13/lib/php
- pear config-set php_ini /usr/local/etc/php/5.4/php.ini
- ✩✩✩✩ Extensions ✩✩✩✩
- If you are having issues with custom extension compiling, ensure that this php is
- in your PATH:
- PATH="$(brew --prefix josegonzalez/php/php54)/bin:$PATH"
- PHP54 Extensions will always be compiled against this PHP. Please install them
- using --without-homebrew-php to enable compiling against system PHP.
- ✩✩✩✩✩ INTL Support ✩✩✩✩✩
- icu4c is broken as of mxcl/homebrew#03ed757c, so you will need to install intl as
- a separate extension:
- brew install php54-intl
- ✩✩✩✩ FPM ✩✩✩✩
- To launch php-fpm on startup:
- * If this is your first install:
- mkdir -p ~/Library/LaunchAgents
- cp /usr/local/Cellar/php54/5.4.13/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/
- launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist
- * If this is an upgrade and you already have the homebrew-php.josegonzalez.php54.plist loaded:
- launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist
- cp /usr/local/Cellar/php54/5.4.13/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/
- launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist
- The control script is located at /usr/local/Cellar/php54/5.4.13/sbin/php54-fpm
- Mountain Lion comes with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /sbin is before /usr/sbin in your PATH:
- PATH="/sbin:$PATH"
- You may also need to edit the plist to use the correct "UserName".
- Please note that the plist was called 'org.php-fpm.plist' in old versions
- of this formula.
- To have launchd start php54 at login:
- ln -sfv /usr/local/opt/php54/*.plist ~/Library/LaunchAgents
- Then to load php54 now:
- launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php54.plist
- Warning: /usr/local/sbin is not in your PATH
- You can amend this by altering your ~/.bashrc file
