LNMP-入门配置-nginx篇

安装完各种环境以后，第二步要做的就是  让nginx 支持PHP
找到 nginx下的default.conf  找到 

     # 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  /scripts$fastcgi_script_name;
     # include fastcgi_params;
     #}

因为nginx默认没有关联PHP，所以此处
将其修改为

    
				
					
						location ~ \.php$ {
        root /usr/share/nginx/html;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_index index.php;
        try_files $uri =403;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        include fastcgi_params;
    }

然后，将解析所有文件处 加上默认 index.php  ，按照先后顺序决定优先解析那种文件

location / {
        root   /usr/share/nginx/html;
        index  index.html index.htm;
    }

修改为

location / {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;
    }

这样 nginx就能解析PHP文件了


另外 此处可加上用socket方式执行php-fpm 来优化速度，具体方式为
找到 php-fpm.d/  然后  修改其中的 

listen = 127.0.0.1:9000

将其改成 

listen = /tmp/php-fcgi.sock

另外注意 权限问题，默认mode 是 0660 重启php-fpm会没办法读取 fcgi 需改成  0666

;listen.owner = php-fpm
;listen.group = php-fpm
listen.mode = 0666

然后 再在nginx解析PHP修改 fastcgi_pass 执行方式为socket  

location ~ \.php$ {
        root /usr/share/nginx/html;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/tmp/php-fcgi.sock;
        fastcgi_index index.php;
        try_files $uri =403;
        fastcgi_param SCRIPT_FILENAME $request_filename;
        include fastcgi_params;
    }

这样php-fpm就是以socket方式执行了

上传文件大小
vim /etc/nginx/nginx.conf
client_max_body_size 10M;
