Symfony

symfony2.8

安装准备

均使用 apt-get 安装

PHP5.4

至少要有个PHP5.4的环境

nginx

web server 是少不了了

安装步骤

1.下载官方命令工具

sudo curl -LsS https://symfony.com/installer -o /usr/local/bin/symfony
sudo chmod a+x /usr/local/bin/symfony

2.创建项目

这里执行项目创建时，会从官网下载源码包，执行完后就能在当前目录看到了

symfony new symfony2.8 2.8

这里我创建了一个新的项目叫symfony2.8， 最后的2.8(不是项目名字中的2.8) 是要下载指定的symfony2.8版本的源码,如果要下载的是其他版本， 修改一下接口

3.检测
在安装完后， symfony还会进行一些检测， 看看你的操作系统环境是否适合运行symfony， 按照提示将缺失的扩展安装(我安装了intl)或者将PHP的配置修改(我就改了时区)，再执行

php symfony2.8/bin/symfony_requirements

再次检测是否通过(php 后面的文件就在新创建的项目中，我这里项目名是symfony2.8)

运行

symfony2.8' 自带的console(位置symfony2.8/bin/console)可以临时启动一个webserver，默认端口是8000,启动后，通过http://localhost:8000` 就能看到他的欢迎页面了

nginx 配置

nginx 的配置其官方文档里也有， 这里直接把我的复制过来，我也是直接修改的官方文档

server {
    listen 8028;
    #server_name domain.tld www.domain.tld;
    root /data/app/symfony2.8/web;

    location / {
        # try to serve file directly, fallback to app.php
        try_files $uri /app.php$is_args$args;
    }
    # DEV
    # This rule should only be placed on your development environment
    # In production, don't include this and don't deploy app_dev.php or config.php
    location ~ ^/(app_dev|config)\.php(/|$) {
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
    }
    # PROD
    location ~ ^/app\.php(/|$) {
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        # When you are using symlinks to link the document root to the
        # current version of your application, you should pass the real
        # application path instead of the path to the symlink to PHP
        # FPM.
        # Otherwise, PHP's OPcache may not properly detect changes to
        # your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
        # for more information).
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        fastcgi_param DOCUMENT_ROOT $realpath_root;
        # Prevents URIs that include the front controller. This will 404:
        # http://domain.tld/app.php/some-path
        # Remove the internal directive to allow URIs like this
        internal;
    }

    # return 404 for all other php files not matching the front controller
    # this prevents access to other php files you don't want to be accessible.
    location ~ \.php$ {
      return 404;
    }

    error_log /data/log/nginx/symfony_error.log;
    access_log /data/log/nginx/symfony_access.log;
}

需要注意的是， nginx中包含了一个在开发环境适用的配置和一个在生产环境适用的配置，在生产华景部署的时候， 一定不要讲开发环境的配置带上去了

配置好后， 重新reload nginx,我这里监听的是虚拟机的8028端口，通过访问这个端口，也可以直接看到欢迎页面
