背景
随着公司的子项目越来越多,会有大大小小十几个工程(仅后端),按照原先的做法,每上线一个项目,那么必须要有一个二级域名映射到对应的工程上,十个工程那么就意味着需要有十个二级域名(还不包含测试环境,次生产环境等),如此多的域名不仅仅是难于管理,更重要的是比较浪费资源,这个问题困扰了我很久,今天终于解决了这个问题,特此记录一下采坑日记,本文不会讲nginx中各个指令的原理,而是用实际的项目配置来练习nginx指令的用法并举一反三。
事先准备
域名
假设域名为:http://www.dev.com
实验环境
阿里云ECS + centos + Nginx + php-fpm
项目1
1.工程路径: /data/wwwroot/project1/
2.访问路径:http://www.dev.com/project1/
项目2
1.工程路径: /data/wwwroot/project2/
2.访问路径:http://www.dev.com/project2/
项目3
1.工程路径: /data/wwwroot/project3/
2.访问路径:http://www.dev.com/project3/
涉及的知识点
Nginx的location指令,用法可以参考:https://www.Vevb.com/article/154637.htm Nginx的alias指令,用法可以参考:https://www.Vevb.com/article/154640.htm实现步骤
为了实现以上的访问形式,我们需要用到nginx里面的location指令和alias指令,配置如下
location ^~ /${PROJECT}/ { alias {$PATH}; try_files $uri $uri/ @${PROJECT}; location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; }}location @${PROJECT}{ rewrite /${PROJECT}/(.*)$ /${PROJECT}/index.php?/$1 last;}
说明: 上面的这个配置中的${PROJECT}和{$PATH}都是属于在实际过程中需要替换的部分,其中${PROJECT}为url需要访问的path部分,如project1,{$PATH}则代表的是项目的真实访问路径,如/data/wwwroot/project1,以http://www.dev.com/project1 访问为例,那么对应的Nginx的配置是这样子的
location ^~ /project1/ { alias /data/wwwroot/project1/public; try_files $uri $uri/ @project1; location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; }}location @project1{ rewrite /project1/(.*)$ /project1/index.php?/$1 last;}
对于project2和project3的配置只需要按照上面的配置模板依葫芦画瓢就可以了,最后完整nginx配置如下
server { listen 80; server_name http://www.dev.com; access_log /data/wwwlogs/nginx/access_log/www.dev.com_nginx.log combined; error_log /data/wwwlogs/nginx/error_log/www.dev.com_errr_log; index index.html index.htm index.php; # project1开始的配置 location ^~ /project1/ { alias /data/wwwroot/project1/public; try_files $uri $uri/ @project1; location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; } } location @project1{ rewrite /project1/(.*)$ /project1/index.php?/$1 last; } # project2开始的配置 location ^~ /project2/ { alias /data/wwwroot/project2/public; try_files $uri $uri/ @project2; location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; } } location @project2{ rewrite /project2/(.*)$ /project2/index.php?/$1 last; } # project2开始的配置 location ^~ /project3/ { alias /data/wwwroot/project3/public; try_files $uri $uri/ @project3; location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; } } location @project3{ rewrite /project3/(.*)$ /project3/index.php?/$1 last; } # 解析所有的.php location ~ /.php$ { fastcgi_pass unix:/dev/shm/php-cgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name; #fastcgi_param SCRIPT_FILENAME $request_filename; include fastcgi_params; } #图片、视频的的链接,此处是做缓存 ,缓存30天,不写入访问日志 location ~ .*/.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ { expires 30d; access_log off; } #js css文件的配置,此处是做缓存 ,缓存7天,不写入访问日志 location ~ .*/.(js|css)?$ { expires 7d; access_log off; } location ~ //.ht { deny all; }}
