Mac安装LNMP环境

这两天在Mac上安装LNMP开发环境，现在整理一下安装的大概步骤及需要注意的点

1. 安装Homebrew

Homebrew是一款Mac系统下的软件包管理工具，brew命令类似ubuntu上的apt-get，能十分方便的在Mac上安装或卸载软件

一句话安装命令

$  /usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2. 安装php

Mac系统上默认安装了php，但是版本为5.5，版本稍微有点低并且有些扩展是没有安装。目前PHP7已经面世，据官方的说法是现在PHP7要比PHP5.6快上一倍，所以我选择重新安装php，并把Mac系统的默认php版本指定为PHP7

// 更新brew
$ brew update

// 添加三方仓库
$ brew tap homebrew/dupes  
$ brew tap homebrew/versions  
$ brew tap homebrew/homebrew-php

// 如果没有该目录，则创建
$ sudo mkdir /usr/local/var
$ sudo chmod 777 /usr/local/var 

$ sudo mkdir /usr/local/sbin/
$ sudo chown -R <username>:<group> /usr/local/sbin/

// 安装php7前，先关闭老版本的PHP55，并解除/usr/local/bin/php软链接
$ brew unlink php55
// 我们可以通过brew options命令来查看安装选项
$ brew options php70
// 开始安装PHP7
$ brew install php70 (--with-apache 假如需要生成apache的libphp7.so，则添加该安装选项)

// 查看php版本
$ php -v
PHP 7.0.13 (cli) (built: Dec  5 2016 14:49:24) ( NTS )
Copyright (c) 1997-2016 The PHP Group
Zend Engine v3.0.0, Copyright (c) 1998-2016 Zend Technologies

3. 配置php及php-fpm

可执行文件及配置文件路径

php, phpize, php-config /usr/local/opt/php70/bin
php-fpm /usr/local/opt/php70/sbin/php-fpm

php.ini /usr/local/etc/php/7.0/php.ini 
php-fpm.conf /usr/local/etc/php/7.0/php-fpm.conf

修改php-fpm配置

$ sudo vim /usr/local/etc/php/7.0/php-fpm.conf

// 为了防止访问无权限，所以修改user及group
user = wanghuiyu
group = staff

// 为了区别不同版本的php-fpm，修改php70-fpm的端口
listen = 127.0.0.1:9001

添加php-fpm为开机启动项

$ mkdir -p ~/Library/LaunchAgents
$ cp /usr/local/opt/php70/homebrew.mxcl.php70.plist ~/Library/LaunchAgents/
$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php70.plist

查看php-fpm是否启动成功

$ ps aux|grep php-fpm
wanghuiyu         973   0.0  0.1  2484880   4636   ??  S    10:58上午   0:00.12 /usr/local/opt/php70/sbin/php-fpm --fpm-config /usr/local/etc/php/7.0/php-fpm.conf
wanghuiyu         436   0.0  0.1  2486928   6288   ??  S    10:08上午   0:00.23 /usr/local/opt/php70/sbin/php-fpm --fpm-config /usr/local/etc/php/7.0/php-fpm.conf
wanghuiyu         435   0.0  0.0  2486928   2628   ??  S    10:08上午   0:00.34 /usr/local/opt/php70/sbin/php-fpm --fpm-config /usr/local/etc/php/7.0/php-fpm.conf
wanghuiyu         434   0.0  0.0  2479792    308   ??  Ss   10:08上午   0:00.45 /usr/local/opt/php70/sbin/php-fpm --fpm-config /usr/local/etc/php/7.0/php-fpm.conf
wanghuiyu        3483   0.0  0.0  2424612    436 s000  R+    2:46下午   0:00.00 grep php-fpm

4. 安装Nginx

$ brew install nginx

添加nginx为开机启动项

$ mkdir -p ~/Library/LaunchAgents
$ cp /usr/local/Cellar/nginx/1.10.2_1/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/
$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

设置权限

// 为了监听1024以下端口，需修改nginx所属者
$ sudo chown root:wheel /usr/local/Cellar/nginx/1.10.2_1/bin/nginx
$ sudo chmod u+s /usr/local/Cellar/nginx/1.10.2_1/bin/nginx

nginx的操作命令

// 启动nginx
sudo nginx

// 重新加载配置|重启|停止|退出 nginx
nginx -s reload|reopen|stop|quit

// 测试配置是否有语法错误
nginx -t

5. 配置nginx

$ sudo vim /usr/local/etc/nginx/nginx.conf

配置nginx虚拟主机

server {
        listen       80;
        server_name  localhost;
        
        # 设定网站根目录
        root /Users/wanghuiyu/PhpstormProjects/stock/public;
        # 网站默认首页
        index index.php index.html index.htm;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location / {
            # 修改为 Laravel 转发规则，否则PHP无法获取$_GET信息，提示404错误
            try_files $uri $uri/ /index.php?$query_string;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        location ~ \.php$ {
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_intercept_errors on;
            fastcgi_pass   127.0.0.1:9001;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /Users/wanghuiyu/PhpstormProjects/stock/public$fastcgi_script_name;
            include        /usr/local/etc/nginx/fastcgi_params;
        }
    }

重启nginx

$ nginx -s quit
$ sudo nginx

6. 安装mysql

MySQL官网下载dmg安装包，手动安装

至此，我们的LNMP环境就安装完成了。
