lnmp环境如何配置自定义的404页面

我们需要修改nginx的配置文件，路径为/usr/local/nginx/conf/nginx.conf，记得将指令fastcgi_intercept_errors设置为开启状态，使得4xx和5xx错误信息被返回到客户端，并允许nginx使用error_page指令响应错误信息。

user  www www;
worker_processes auto;
error_log  /home/wwwlogs/nginx_error.log  crit;
pid   /usr/local/nginx/logs/nginx.pid;

#Specifies the value for maximum file descriptors that can be opened by this process.
worker_rlimit_nofile 51200;

events  {
                use epoll;
                worker_connections 51200;
                multi_accept on;
        }

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

                ...
                #这个指令一定要设置为开启状态
                fastcgi_intercept_errors on;
                ...
server {
                listen 80 default;
                server_name www.example.com;
                index index.html index.htm index.php;
                root  /home/wwwroot/default;

                 #全局404页面，默认会到配置的root路径下查找，示例
                error_page   404 = /404.html;

                #模块404页面，配置的是全路径，示例
                #location /mycms {
                #   error_page 404 = http://192.168.100.168/mycms/404.html;
               # }

                location ~ [^/]\.php(/|$)
                {
                    #comment try_files $uri =404; to enable pathinfo
                    try_files $uri =404;
                    fastcgi_pass  unix:/tmp/php-cgi.sock;
                    fastcgi_index index.php;
                    include fastcgi.conf;
                    #include pathinfo.conf;
                }

                location /nginx_status {
                    stub_status on;
                    access_log   off;
                }

                location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
                {
                   expires      30d;
                }

                location ~ .*\.(js|css)?$
                {
                   expires      12h;
                }

                access_log  /home/wwwlogs/access.log  access;
        }
          include vhost/*.conf;
}

注意：修改完配置过后记得重启Nginx

[root@server1 ~]#  /usr/local/nginx/sbin/nginx -t  //检查配置是否正确
[root@server1 ~]#  /usr/local/nginx/sbin/nginx -s reload //重启Nginx

因为是lnmp环境，我们也可以使用lnmp命令重启所有服务：

[root@server1 ~]#  lnmp restart
