ftp:filezilla客户端下载

数据库:mysql下载 安装后系统偏好设置有个Mysql图标,可以启动Mysql服务。

mysql配置:/usr/local/mysql/为maysql目录
设置mysql不需要密码,经常出错没有root密码,干脆不要密码,等创建完用户记得删掉,个人电脑就无所谓了,要密码还麻烦。

sudo cp /usr/local/mysql/support-files/my-default.cnf /etc/my.cnf
sudo vi /etc/my.cnf
#[mysqld]下添加
skip-grant-tables
#esc :wq!

apache:mac自带了apache,不需要安装,看了下版本是2.4.16,官方是2.4.20,还可以。apache服务的目录/etc/httpdctl或者/usr/sbin/httpd,模块目录/usr/libexec/apache2/,配置文件目录/etc/apache2/。启动服务:sudo apachectl start

配置apache

sudo vi /etc/apache2/httpd.conf
#查找字符串AddType,并增加
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps

#  libpng:        yes (pkg-config)
#  harfbuzz:      no  (pkg-config)
brew install harfbuzz

进入到php/ext/gd/

make clean
#重新编译GD之前一定要make clean就是因为忘记了这个找个半天错误。
phpize
./configure --with-php-config=/usr/local/php/bin/php-config --with-freetype-dir=/usr/local/freetype
make
sudo make install
