mac下安装php7.2、mysql5.7、nginx环境

本篇文章是通过homebrew安装，home brew对于Mac相当于centos 的yum一样方便简单，大家可以先去安装home brew。网上很多简单靠谱的例子，这里不写了

一、准备条件
为了安装最新的配置，我们提前升级brew

brew update

二、安装PHP7
1、安装php7.2

brew install php72

如果你的系统已经安装其他版本，报错可能如下

➜  ~ brew install php72

==> Installing php72 from homebrew/php
Error: Cannot install homebrew/php/php72 because conflicting formulae are installed.
php55: because different php versions install the same binaries.
Please `brew unlink php55` before continuing.   //也就是你的系统已经安装php5.5
Unlinking removes a formula's symlinks from /usr/local. You can
link the formula again after the install finishes. You can --force this
install, but the build may fail or cause obscure side-effects in the
resulting software.

那么你可以卸载当前系统下的php5.5版本

brew unlink php55

然后继续安装

2、配置文件位置
好安装后生成的配置文件都在/usr/local/etc/php/7.2目录里，分别如下：
php.ini位置为/usr/local/etc/php/7.2/php.ini
php-fpm.conf位置为/usr/local/etc/php/7.2/php-fpm.conf
PHP运行phpize，PHP-配置ls /usr/local/opt/php72/bin
PHP-FPM位置为/usr/local/opt/php72/sbin/php-fpm

3、将php7加入开机启动

mkdir -p ~/Library/LaunchAgents ln -sfv /usr/local/opt/php72/homebrew.mxcl.php72.plist ~/Library/LaunchAgents/ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php72.plist

4、将php加入$PATH

vim ~/.bash_profile

//添加以下命令
export PATH="/usr/local/sbin:$PATH"
export PATH="$(brew --prefix php72)/bin:$PATH"
export PATH="$(brew --prefix php72)/sbin:$PATH"
export PATH="/usr/local/bin:/usr/local/sbin:$PATH"

//保存配置
source ~/.bash_profile

6、查看是否安装成功

lsof -Pni4 | grep LISTEN | grep php

//结果，表示安装成功了
php-fpm   27683 wangteng    8u  IPv4 0xab953b14ed200d5d      0t0  TCP 127.0.0.1:9000 (LISTEN)
php-fpm   27686 wangteng    9u  IPv4 0xab953b14ed200d5d      0t0  TCP 127.0.0.1:9000 (LISTEN)
php-fpm   27687 wangteng    9u  IPv4 0xab953b14ed200d5d      0t0  TCP 127.0.0.1:9000 (LISTEN)
phpstorm  99685 wangteng  176u  IPv4 0xab953b14c83636dd      0t0  TCP 127.0.0.1:6942 (LISTEN)
phpstorm  99685 wangteng  351u  IPv4 0xab953b14fa71ca5d      0t0  TCP 127.0.0.1:63342 (LISTEN)

7、重启php7
如果我们修改配置，需要重启一下php7

brew services restart php72

三、安装Nginx

1、安装

brew install nginx

通过homebrew，nginx文件默认被安装在/usr/local/etc/nginx/nginx.conf，然后再浏览器中键入http://localhost:8080,即可访问到nginx的欢迎界面。

2、配置
配置文件地址

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

nginx安装完访问本地默认的目录是    /usr/local/Cellar/nginx/1.15.12/html

在nginx的配置文件最下面有一个引入所有的一行代码，可以在这个目录下（server）创建不同的站点。

添加如下代码，每个意义看备注，多站点直接复制如下代码重新粘贴，然后修改root，server_name重启nginx即可

server {
        listen 80;
        root /usr/local/etc/nginx/www/cat/public;  #项目文件地址          
        index index.php index.html index.htm;
        server_name web.cat.com; #本地域名，可以在host里定义
        location / {
                try_files $uri $uri/ /index.php?$query_string;
        }
        location ~ .php$ {
                try_files $uri /index.php =404;
                fastcgi_split_path_info ^(.+.php)(/.+)$;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
        }
        location ~ /.ht {
                deny all;
        }
}

配置完成我们可以重启nginx，让配置生效：

nginx -s reload

3、Nginx命令：

//测试配置是否有语法错误
nginx -t

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

也可以使用Mac的launchctl来启动|停止

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

Nginx开机启动,不过推荐自己启动

ln -sfv /usr/local/opt/nginx/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

四、安装MySQL

//直接安装
brew install mysql@5.7

设置MySQL的开机自启动：

ln -sfv /usr/local/opt/mysql@5.7/*.plist ~/Library/LaunchAgents
/Users/wangteng/Library/LaunchAgents/homebrew.mxcl.mysql@5.7.plist -> /usr/local/opt/mysql@5.7/homebrew.mxcl.mysql@5.7.plist

增加环境变量

export PATH="/usr/local/opt/mysql@5.7/bin:$PATH"

增加完环境变量别忘了使之生效

然后启动mysql

mysql.server start

测试数据库是否安装成功

mysql -u root -p  //因为没有设置密码，两次回车即可

查看网络监听

$ netstat -nat | grep LISTEN
tcp4       0      0  127.0.0.1.3306         *.*                    LISTEN
