原文:Mac 下 Nginx、PHP、MySQL 和 PHP-fpm 的安装和配置
个人博客永久地址。

文章做了更新，增加了php-fpm的配置相关信息。

Mac下搭建MNPM环境是每个使用者mac的phper必备的技能。一般都是找到新工作入职的第一天做的事情－－配置环境。

如上，今天入职的，配置开发环境。公司配备的硬件设备很屌，15年产macbook pro笔记本一台（13寸），配置了8GB DDR3内存，2.7GHz core i5处理器，120GB的闪存。当然了，没我自己买的配置高，哈哈～～

home-brew是什么？先这样说吧，home-brew与OS X就像nodes与npm，java与maven（或者gradle），php与composer，apt-get与Ubutun，yum与centos,还有其他等等吧，都是宿主的开发工具或包的依赖管理。

安装Homebrew之前，先安装xcode命令行工具，安装成功后，打开xcode的应用，查看Xcode是否为最新，如果不是最新的请在App Store中升级Xcode。

安装xcode命令行工具的命令：

xcode-select --install

安装完后，请使用brew doctor命令检查当前环境是否最新符合brew运行，如果xcode的版本太低，则会有相应的提示信息。

home-brew的安装很容易，只要你的客户终端安装了ruby即可，其实，你一点都不用担心此事，OS X系统已经预装了ruby。

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

网上很多关于安装homebrew的文章相较时间早，所以很多文章依然提供下面这种安装，其实测试发现改地址已经返回404，并不能提供资源服务。

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

关于Homebrew的更多知识，请参见下面几个站点的链接。

Mac系统下类似于apt-get的软件包管理器--Homebrew

安装好了Homebrew之后，便可以使用brew命令来安装相应的包了。接下来，安装nginx服务器。

brew install nginx

如果需要安装nginx的其他版本，可以使用brew edit nginx来修改其内容：

> class Nginx < Formula   desc "HTTP(S) server and reverse proxy, and
> IMAP/POP3 proxy server"   homepage "http://nginx.org/"   url
> "http://nginx.org/download/nginx-1.10.0.tar.gz"   sha256

从上面信息可以看出nginx的下载地址等信息，可以根据自己的需求修改。

brew执行完之后，nginx服务器就算安装好了，运行下面几条命了测试一下：

# 启动 nginx服务
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

nginx启动后，在浏览器中输入http://localhost:8080/,回车即可看到运行结果，显示的是/usr/local/Cellar/nginx/1.10.0/html/index.html文件的内容。

相关参数可自行修改，具体怎么配置nginx，请参看nginx的配置。

实际上，nginx服务的启动可以用-c nginx的配置文件参数制定其配置文件，默认加载／usr/local/etc/nginx/nginx.conf文件，当然nginx的操作不止这些命令，还有一些信号操作，关于nginx的信号操作等知识，留在它章详细的说一下。

# 启动 nginx
sudo ngixn -c /usr/local/etc/nginx/nginx.conf

#测试配置是否有语法错误
nginx -t -c /usr/local/etc/nginx/nginx.conf

补充

开机自启动nginx服务设置：

mkdir -p ~/Library/LaunchAgents
cp /usr/local/Cellar/nginx/1.10.0/homebrew.mxcl.nginx.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.nginx.plist

配置非管理员开机nginx自动启动的权限和分组：

sudo chown root:wheel /usr/local/Cellar/nginx/1.10.0/sbin/nginx
sudo chmod u+s /usr/local/Cellar/nginx/1.10.0/sbin/nginx

安装mysql同nginx一样简单，执行brew命令：

brew install mysql

执行完brew命令，如果没有出错，mysql算是安装到本机或者服务器了，当然，此过程会看到很多信息打印到shell窗口。

接下来，我们执行一些简单的配置命令。

a.初始化mysql数据库：

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql

这里需要说明一下，网上很多资料显示需要tmpdir参数，如下：

mysql_install_db --verbose --user=`whoami` --basedir="$(brew --prefix mysql)" --datadir=/usr/local/var/mysql --tmpdir=/tmp

这个会出错，具体原因暂时不知道，在segmentfault上有人提问过了，目前没有完美的答案。

b.查看mysql数据库是否启动，如果没有启动则使用mysqld命令启动。

ps -ef | grep mysql

如果没有启动，使用安装的mysql目录下的mysqld命令启动mysql：

／usr/local/Cellar/mysql/5.7.12/bin/mysqld

当然，你可直接使用/usr/local/bin/mysqld就可以启动mysql服务。

which mysqld

结果发现：

> MacBook-Pro:joyven $ which mysql
> /usr/local/bin/mysqld

此时的数据库没有密码，即使是root用户，也无需密码就可登录到数据库服务。因此，需要设置数据库密码：

/usr/local/bin/mysqladmin -u root password "new-password"

现在访问 mysql 还是不用密码就可以连接，如果要设置一些登陆密码的安全访问限制，则需执行下面的 mysql安全安装指令:

/usr/local//bin/mysql_secure_installation

主要是设置修改root密码（设置过了可以不用设置，略过）、删除匿名访问、删除root网络访问、删除test数据库。指令执行完后，登陆mysql就需要密码验证了:

mysql -u root -p

开机启动 mysql

mkdir -p ~/Library/LaunchAgents/
cp /usr/local/Cellar/mysql/5.7.12/homebrew.mxcl.mysql.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

如果要停止 mysql 服务则：

launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist

php的安装很简单，php－fpm目前已经集成到php的内核，可以当作内核来安装了。很久以前不是哦，请注意，我不记得是什么时候加入到内核的，如果你乐意查，查了请在评论区告诉我一下。

至于他为什么是内核的原因，参考《搞不清FastCgi与PHP-FPM之间是个什么样的关系》的提问，主要看看下面各位大神@的回答。

安装php之前，请先用brew tap命令引入第三方的php库，brew仓库中没有php的安装包。

brew tap homebrew/dupes
brew tap josegonzalez/homebrew-php

万事俱备，只欠东风，不，只欠一条命令。

To enable PHP in Apache add the following to httpd.conf and restart Apache:
LoadModule php5_module    
/usr/local/opt/php56/libexec/apache2/libphp5.so
The php.ini file can be found in:
/usr/local/etc/php/5.6/php.ini

✩✩✩✩ Extensions ✩✩✩✩
If you are having issues with custom extension compiling, ensure that you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:
  PATH="/usr/local/bin:$PATH"

PHP56 Extensions will always be compiled against this PHP. Please install them using --without-homebrew-php to enable compiling against system PHP.
✩✩✩✩ PHP CLI ✩✩✩✩
If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc, ~/.zshrc, ~/.profile or your shell"s equivalent configuration file:
  export PATH="$(brew --prefix homebrew/php/php56)/bin:$PATH"

✩✩✩✩ FPM ✩✩✩✩
To launch php-fpm on startup:
mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php56/homebrew.mxcl.php56.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php56.plist

The control script is located at /usr/local/opt/php56/sbin/php56-fpm
OS X 10.8 and newer come with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:
PATH="/usr/local/sbin:$PATH"
You may also need to edit the plist to use the correct "UserName".
Please note that the plist was called "homebrew-php.josegonzalez.php56.plist" in old versions of this formula.

我我什么要把这些信息贴出来，原因很简单，这些信息给我给出了我们安装是否成功，安装在那个路径下了，接下来我们还需要手动做些什么（比如开机启动等）。

由于Mac系统预装了php以及php-fpm，所以，为了启动的时候能直接启动安装的最新的php，请把php安装的二进制文件所在的路径加入到系统路径中，这个地方需要注意了。如果我们设置了开机的时候自动启动，我们不会发现有什么问题，可是当我重新配置了扩展，需要重新启动php-fpm的时候，我们如果直接使用php-fpm -c /usr/local/etc/php/5.6/php.ini -y /usr/local/ext/php/5.6/php-fpm.conf的时候，我们发现我们的扩展安装没有起作用，原因是我们使用了/usr/sbin/php-fpm的命令，可以通过which查看。所以需要注意，使用brew安装的php-fpm是在/usr/local/opt/php56/目录下面。：

export PATH="$(brew --prefix php54)/bin:$PATH"

到此，php以及PHP－fpm已经安装成功了。那么我们还是设置php－fpm开机启动，在哪里找这段代码呢，安装过程打印的信息，也就是我为什么要把安装过程信息完完整整贴一遍的原因：

mkdir -p ~/Library/LaunchAgents
cp /usr/local/opt/php56/homebrew.mxcl.php56.plist ~/Library/LaunchAgents/
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php56.plist

ps:
顺便说一下或许对你在安装过程很有用的命令：

杀死一个进程的命令：

    sudo kill -9 pid #pid替换为你的进程号

比如你要杀死php-fpm进程，也可以使用如下命令：

    sudo killall php-fpm
    // 或者
    sudo killall -HUP php-fpm

如何查看进程号：

    ps -ef | grep php-fpm

Nginx服务器的配置，这里只作简单的配置部分说明，至于想对较为繁琐的配置，比如ip_hash,upstream,gzip,反向代理等内容放到它章作解。

假如你的网站根目录是在/var/www下面，那么我们只需配置一个简单的站点作为nginx配置的开始。

前面说过了，Mac下nginx的配置文件的默认存放路径－－/usr/local/etc/nginx/，改文件下包括如下几个文件（夹）：

fastcgi.conf
mime.types
servers
fastcgi.conf.default
mime.types.default
sites-enabled
fastcgi_params
nginx.conf
uwsgi_params
fastcgi_params.default
nginx.conf.default
uwsgi_params.default
koi-utf
scgi_params
win-utf
koi-win
scgi_params.default

默认情况下，没有sites-enabled这个文件夹，这个时我们为了方便管理配置的server节点，创建的一个文件夹。创建命令：sudo mkdir sites-enabled。

配置中经常用到一个nginx的参数，提供参数的两个文件时fastcgi.conf和fastcgi_params，这两个文件除了SCRIPT_FILENAME这个参数之外，其他一模一样，为什么要一模一样呢，具体自省Google，这里是说，先有fastcgi_params，后有fastcgi.conf，所以大多数的时候我们看到配置中很多人还是喜欢继续用fastcgi_params。

nginx.conf的基本配置：

#user  nobody;
worker_processes  4;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

上面的太乱了，我们简化一下吧：

worker_processes  4;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;

    log_format  main  "$remote_addr - $remote_user [$time_local] "$request" "
                      "$status $body_bytes_sent "$http_referer" "
                      ""$http_user_agent" "$http_x_forwarded_for"";

    access_log  /usr/local/var/log/nginx/access.log  main;

    sendfile        on;
    keepalive_timeout  65;


    server {
        listen       80;
        server_name  localhost;

        charset utf-8;

        access_log  /usr/local/var/log/nginx/localhost.access.log  main;

        root /var/www; #你的网站根目录
        location / {
            index  index.html index.htm index.php;
        try_files $uri /$uri index.php?$args;
        }
     

        error_page  404              /404.html;
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        location ~ .php$ {
            fastcgi_pass   127.0.0.1:9000;
            fastcgi_index  index.php;
            fastcgi_param  SCRIPT_FILENAME  /var/www$fastcgi_script_name;
            include        fastcgi_params;
        }
   
        location ~ /.ht {
            deny  all;
        }
    }

    include sites-enabled/nginx-*.conf;

这是一份相对简单的nginx配置，相对复杂一点的配置会在复杂的场景中使用，一般初步开发这些就可以满足了。

下面给出一份sites-enabled文件夹下的nginx的配置。需要说明的是，上面的配置中的server节点中的内容，包括server，可以多带带拿出来，放在一份多带带的配置中，由最后一句的include的命令引入。

nginx-test.conf

server {
    listen 80;
    server_name test-local.com;

    charset utf-8;
    access_log /usr/local/var/log/nginx/test-local.com.access.log main;
    error_log /usr/local/var/log/nginx/test-local.com.error.log;

    root /var/www/test-php/backend/web;

    location / {
        try_files $uri $uri/ /index.php?$args;
        index index.html index.htm index.php;
    }

    location ~ .php$ {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /var/www/test-php/backend/web$fastcgi_script_name;
        include fastcgi_params;
        try_files $uri =404;
    }
}     

如上，打开浏览器输入http://localhost/访问第一个server节点配置的服务，输入http://test-local.com/访问第二个server节点。

但是，别太急，请修改hosts的host配置，打开/etc/hosts文件，加入一行：

127.0.0.1 test-local.com

大多数时候，我们不得不安装php的扩展，比如 GD,mcrypt,CURL,XML,MEMCACHED 等扩展配置，这些东西在我们的开发中常常用到，对于几个相对较难的扩展，做一些记录吧。

curl安装

mcrypt安装

memcached安装
