php.ini的位置
Mac OS X中沒有默認的php.ini文件，但是有對應的模版文件php.ini.default，位於/private/etc/php.ini.default 或者說 /etc/php.ini/default ，可以自行拷貝一份進行修改。
sudo cp /private/etc/php.ini.default /private/etc/php.ini
mac編譯apache時出現 checking whether the C compiler works... no 的解決辦法
在MAC下編譯apache時執行 ./configure 出現如下錯誤。
checking for gcc... /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc
checking whether the C compiler works... no
configure: error: in /Users/hufeiyan/ws/httpd-2.2.26': configure: error: C compiler cannot create executables See config.log' for more details
查看config.log有如下描述：(config.log文件在apache的文件夾下)
configure:4480: result: /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain/usr/bin/cc
configure:4709: checking for C compiler version

解決辦法：
在命令行執行如下命令：
sudo ln -s /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/ /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain
其中/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/是固定寫法，/Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.9.xctoolchain 可以在config.log中找到
如何解決:sorry,i cannot run apxs.possible reasons follow
.在編譯安裝php5.2的時候出現下面錯誤:sorry,i cannot run apxs.possible reasons follow:
Sorry, I cannot run apxs. Possible reasons follow:
1. Perl is not installed
2. apxs was not found. Try to pass the path using --with-apxs2=/path/to/apxs
3. Apache was not built using --enable-so (the apxs usage page is displayed)
解決方法:根據英文提示我們可以看到如下幾點:perl沒有安裝,指定正確的apxs路徑
於是進行如下操作:
yum install perl* 之前是yum install perl
終端輸入：find / -name apxs 得到的路徑是:/usr/sbin/apxs
於是修改--with-apsx2=/usr/sbin/apxs指定到正確路徑
最后正確執行
configure: error: xml2-config not found. Please check your&nb
安裝php時的報錯
checking libxml2 install dir... no
checking for xml2-config path...
configure: error: xml2-config not found. Please check your libxml2 installation.
安裝完之后查找xml2-config文件是否存在
[root@XKWB3403 php-5.3.8]# find / -name "xml2-config"
/usr/bin/xml2-config
重新安裝libxml2和libxml2-devel包
brew install libxml2
如果還是報錯。就執行下邊的命令：
首先進入php的安裝文件的目錄：
cd /path/php;
然后使用下邊的命令：
./configure --with-libxml-dir=/usr/local/Cellar/libxml2/2.9.3/
沒有特殊情況的話，會出現下邊的成功提示：

更新brew
調用brew update如果出現下邊的錯誤：
Error: The /usr/local directory is not writable.
Even if this directory was writable when you installed Homebrew, other
software may change permissions on this directory. For example, upgrading
to OS X El Capitan has been known to do this. Some versions of the
"InstantOn" component of Airfoil or running Cocktail cleanup/optimizations
are known to do this as well.
You should probably change the ownership and permissions of /usr/local
back to your user account.
sudo chown -R $(whoami):admin /usr/local
在終端中運行sudo chown -R $(whoami):admin /usr/local后，然后運行brew update.
