Symfony安装及使用
安装Symfony，使用
brew install homebrew/php/symfony-installer
开始一直下载不了包，我手动浏览器下载了几个，发现好像都是Permission问题，运行了下面的命令：
sudo chown -R $(whoami) /Users/baidu/Library/Caches/Homebrew/
Symfony安装在：
$ which symfony
/usr/local/bin/symfony
在以下目录：
/Users/baidu/Documents/Data/Work/Installed/symfony
运行
symfony new mywebsite 2.8
一直超时。
所以就自己到Symfony下了个demo，解压到html根目录，然后运行
http://127.0.0.1:7080/symfony-demo/web/config.php
发现两个major问题：
- Vendor libraries must be installed
Vendor libraries are missing. Install composer following instructions from http://getcomposer.org/. Then run "php composer.phar install" to install them.
- date.timezone setting must be set
Set the "date.timezone" setting in php.ini* (like Europe/Paris).
发现还是有很多问题。
连上公司网络，然后重新进行命令：
symfony new mywebsite 2.8 -vvv
初步看来可以运行。
安装成功会显示：
? Symfony 2.8.12 was successfully installed. Now you can: * Change your current directory to /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite * Configure your application in app/config/parameters.yml file. * Run your application: 1. Execute the php app/console server:run command. 2. Browse to the http://localhost:8000 URL. * Read the documentation at http://symfony.com/doc
来到mywebsite目录下面，跑命令
php app/console server:run 开始会出现以下错误：
[Symfony\Component\Debug\Exception\ContextErrorException] Warning: date_default_timezone_get():需要 sudo vi /private/etc/php.ini (没有的话，从php.ini.template拷贝过来)
date.timezone = Asia/Shanghai
然后运行成功：
[OK] Server running on http://127.0.0.1:8000
页面展现：

下一步是要把Nginx和Symfony结合起来。
nginx的配置文件 /usr/local/etc/nginx/nginx.conf
#user nobody;worker_processes 1;#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#pid logs/nginx.pid;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 logs/access.log main; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on; server { listen 8080; server_name localhost; #charset koi8-r; #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #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; } # proxy the PHP scripts to Apache listening on 127.0.0.1:80 # #location ~ \.php$ { # proxy_pass http://127.0.0.1; #} # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000 # location ~ \.php$ { root html; fastcgi_pass 127.0.0.1:9000; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; include fastcgi_params; } # deny access to .htaccess files, if Apache‘s document root # concurs with nginx‘s one # #location ~ /\.ht { # deny all; #} } # another virtual host using mix of IP-, name-, and port-based configuration # #server { # listen 8000; # listen somename:8080; # server_name somename alias another.alias; # location / { # root html; # index index.html index.htm; # } #} # HTTPS server # #server { # listen 443 ssl; # server_name localhost; # ssl_certificate cert.pem; # ssl_certificate_key cert.key; # ssl_session_cache shared:SSL:1m; # ssl_session_timeout 5m; # ssl_ciphers HIGH:!aNULL:!MD5; # ssl_prefer_server_ciphers on; # location / { # root html; # index index.html index.htm; # } #} include servers/*;}
Symfony的配置文件/usr/local/etc/nginx/servers/mywebsite.conf ：
log_format logformat ‘$remote_addr - $remote_user [$time_local] "$request" ‘‘$status $body_bytes_sent "$http_referer" ‘‘"$http_user_agent" "$http_x_forwarded_for"‘;server { listen 7080; server_name localhost; index app.php; root /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/web; location / { if (!-e $request_filename){ rewrite ^/(.+)$ /app.php/$1 last; } client_max_body_size 20M; } location ~ ^/(app|app_dev)\.php(/|$) { fastcgi_pass 127.0.0.1:9000; fastcgi_split_path_info ^(.+\.php)(/.*)$; include fastcgi_params; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; fastcgi_param HTTPS off; client_max_body_size 20M; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 1h; client_max_body_size 20M; } access_log /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/log/mywebsite.log logformat; error_log /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/log/mywebsite.error_log;}
以上全部完成后，运行命令：
$ brew services restart nginx得到输出：Stopping `nginx`... (might take a while)==> Successfully stopped `nginx` (label: homebrew.mxcl.nginx)==> Successfully started `nginx` (label: homebrew.mxcl.nginx)
但是浏览器页面出现如下错误：
Warning: date_default_timezone_get(): It is not safe to rely on the system‘s timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone ‘UTC‘ for now, but please set date.timezone to select your timezone. in /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/app/cache/prod/classes.php on line 6526
开始试了，是不是要改php7的配置
vi /usr/local/etc/php/7.0/php.ini date.timezone = "Asia/Shanghai"发现还是报错，看了一下，需要改两个地方：
一是php的配置文件
vi /etc/php.inidate.timezone = "Asia/Shanghai"二是报错的代码中加上：
vi /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/app/cache/prod/classes.php6526行 加上 date_default_timezone_set(‘Asia/Shanghai‘);：if (!static::$timezone) {date_default_timezone_set(‘Asia/Shanghai‘);static::$timezone = new \DateTimeZone(date_default_timezone_get() ?:‘UTC‘);}
然后就不报错了。
浏览器页面正常显示（Nginx）：
http://127.0.0.1:8080/Welcome to nginx!If you see this page, the nginx web server is successfully installed and working. Further configuration is required.For online documentation and support please refer to nginx.org.Commercial support is available at nginx.com.Thank you for using nginx.
(Symfony):
http://localhost:7080/Welcome toSymfony 2.8.12Your application is now ready. You can start working on it at: /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/What‘s next?Read the documentation to learnHow to create your first page in Symfony
Symfony还有一个debug模式，访问的url是：
http://localhost:7080/app_dev.php/ （区别在于：1. 错误提示到页面，2无缓存）
开始访问的时候，还是报timezone的错，
然后根据提示，在
vi /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/app/cache/dev/classes.php 6008行加上：
date_default_timezone_set(‘Asia/Shanghai‘);
就不报错了，页面显示：
Welcome toSymfony 2.8.12Your application is now ready. You can start working on it at: /Users/baidu/Documents/Data/Work/Installed/symfony/mywebsite/What‘s next?Read the documentation to learnHow to create your first page in Symfony
