1. 安装brew

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/Homebrew.sh)"

我选择的是USTC镜像，速度很快。若需卸载，可以执行

/bin/zsh -c "$(curl -fsSL https://gitee.com/cunkai/HomebrewCN/raw/master/HomebrewUninstall.sh)"

2. 配置系统自带php

php -i|grep 'Loaded Configuration File'

我输出/etc/php.ini， vim编辑(sudo)该文件，修改如下

;doc_root=
cgi.fix_pathinfo=0
do_mysql.default_socket= /tmp/mysql.sock 
mysqli.default_socket = /tmp/mysql.sock 

其中，这里的socket路径可以通过后面安装mysql后，登陆mysql后，使用
show variables like '%socket%';查询。

3. 配置系统自带php-fpm
   我的配置文件在/private/etc/php-fpm.conf, 可以通过copy得到

cp /private/etc/php-fpm.conf.default /private/etc/php-fpm.conf

我只修改了

error_log = /usr/local/var/log/php-fpm/php-fpm.log

检查安装是否正常

php-fpm -v

4. 安装phpmyadmin

brew install phpmyadmin

修改/etc/phpmyadmin/config.inc.php

$cfg['Servers'][$i]['host'] = '127.0.0.1';

5. 安装mysql

brew install mysql

修改/usr/local/etc/my.cnf

# Default Homebrew MySQL server config
[mysqld]
# Only allow connections from localhost
bind-address = 127.0.0.1
mysqlx-bind-address = 127.0.0.1
tmpdir=/tmp
user=root

执行mysql_secure_installation, 并进行相关安全性设置。
terminal登陆mysql

mysql -h localhost -u root -p

然后输入

ALTER USER 'root'@'localhost' IDENTIFIED WITH mysql_native_password
BY 'password';  

注意将password改为你登陆mysql的密码。

5. 安装nginx

brew install nginx

安装结束后可以看到服务器配置文件在/usr/local/etc/nginx/servers/, 也可以通过brew info nginx查看该路径。
我们在该目录下修改default为

server {
  charset utf-8;
  client_max_body_size 128M;

  listen 80; ## listen for ipv4

    server_name localhost;
  root        /usr/local/var/www;
  index       index.php index.html index.htm;

  access_log /usr/local/var/www/log/access.log;
  error_log   /usr/local/var/www/log/error.log;

  location / {
# Redirect everything that isn't a real file to index.php
    try_files $uri $uri/ /index.php$is_args$args;
  }

  error_page 404 /404.html;

# deny accessing php files for the /assets directory
  location ~ ^/assets/.*\.php$ {
    deny all;
  }


  location ~ \.php$ {
    fastcgi_pass   127.0.0.1:9000;
    fastcgi_index  index.php;
    fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
    include        fastcgi_params;
  }

  location  /phpmyadmin {
    root /usr/local/share;
    index index.php index.html index.htm;
    location ~ \.php$ {
      try_files $uri =404;
      include fastcgi_params;
      fastcgi_pass   127.0.0.1:9000;
      fastcgi_index  index.php;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }
  }

  location ~* /\. {
    deny all;
  }
}

6. 打开http://localhost/phpmyadmin应该可以进入phpmyadmin
7. 在目录/usr/local/var/www下新建文件index.php, 内容如下

<?phpinfo(); ?>

访问http://localhost/index.php应该可以看到php配置信息。
