nginx怎么配置多个web

Posted 2023-05-04

参考技术A 对于配置列表中的web服务站点，nginx是定时检测其可用性的。 你说的需要访问多次就能访问到，那只是一个假象。其实是刚好nginx完成了管辖下的站点的检查，将刚重启的tomcat加入到了可用列表中；在你的请求到达时，被转发到了这个tomcat。

nginx_include发布多个web站点

我们有了一个 VPS 主机以后，为了不浪费 VPS 的强大资源（相比共享主机1000多个站点挤在一台机器上），往往有想让 VPS 做点什么的想法，银子不能白花啊:)。放置多个网站或者博客是个不错的想法，可是如何配置 web 服务器才能在一个 VPS 上放置多个网站/博客呢？如何通过一个 IP 访问多个站点/域名呢？这就是大多数 web 服务器支持的 virtual hosting 功能。这里将描述如何一步一步如何用 nginx 配置 virtual hosting。

nginx 是一个小巧高效的 web 服务器，由俄罗斯程序员 Igor Sysoev 开发，nginx 虽然体积小，但功能一点也不弱，能和其他的 web 服务器一样支持 virtual hosting，即一个IP对应多个域名以支持多站点访问，就像一个IP对应一个站点一样，所以是”虚拟”的。你想在一个 IP 下面放多少个站点就放多少，只要硬盘够大就行。
这里以配置2个站点（2个域名）为例，n 个站点可以相应增加调整，

假设：
IP地址:?202.55.1.100
域名1?example1.com?放在?/www/example1
域名2?example2.com?放在?/www/example2

配置 nginx virtual hosting 的基本思路和步骤如下：
把2个站点?example1.com,?example2.com?放到?nginx?可以访问的目录?/www/
给每个站点分别创建一个?nginx?配置文件?example1.com.conf，example2.com.conf,
并把配置文件放到?/etc/nginx/vhosts/
然后在?/etc/nginx.conf?里面加一句?include?把步骤2创建的配置文件全部包含进来（用?*?号）
重启?nginx

具体过程?
下面是具体的配置过程：
1、在 /etc/nginx 下创建 vhosts 目录
mkdir?/etc/nginx/vhosts

2、在 /etc/nginx/vhosts/ 里创建一个名字为 example1.com.conf 的文件，把以下内容拷进去
server?{
????????listen??80;
????????server_name??example1.com?www.?example1.com;
????????accesslog??/www/access?example1.log??main;
????????location?/?{
????????????root???/www/example1.com;
????????????index??index.php?index.html?index.htm;
????????}
????????error_page???500?502?503?504??/50x.html;
????????location?=?/50x.html?{
????????????root???/usr/share/nginx/html;
????????}
???????#?pass?the?PHP?scripts?to?FastCGI?server?listening?on?127.0.0.1:9000
????????location?~?.php$?{
????????????fastcgi_pass???127.0.0.1:9000;
????????????fastcgi_index??index.php;
????????????fastcgi_param??SCRIPT_FILENAME??/www/example1.com/$fastcgi_script_name;
????????????include????????fastcgi_params;
????????}
????????location?~?/.ht?{
????????????deny??all;
????????}
}

3、在 /etc/nginx/vhosts/ 里创建一个名字为 example2.com.conf 的文件，把以下内容拷进去
server?{
????????listen??80;
????????server_name??example2.com?www.?example2.com;
????????accesslog??/www/access?example1.log??main;
????????location?/?{
????????????root???/www/example2.com;
????????????index??index.php?index.html?index.htm;
????????}
????????error_page???500?502?503?504??/50x.html;
????????location?=?/50x.html?{
????????????root???/usr/share/nginx/html;
????????}
???????#?pass?the?PHP?scripts?to?FastCGI?server?listening?on?127.0.0.1:9000
????????location?~?.php$?{
????????????fastcgi_pass???127.0.0.1:9000;
????????????fastcgi_index??index.php;
????????????fastcgi_param??SCRIPT_FILENAME??/www/example2.com/$fastcgi_script_name;
????????????include????????fastcgi_params;
????????}
????????location?~?/.ht?{
????????????deny??all;
????????}
}

4、打开 /etc/nginix.conf 文件，在相应位置加入 include 把以上2个文件包含进来
user??nginx;
worker_processes??1;
#?main?server?error?log
error_log???????/var/log/nginx/error.log?;
pid?????/var/run/nginx.pid;
events?{
????????worker_connections??1024;
}
#?main?server?config
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"‘;
????????sendfile????????on;
????????#tcp_nopush?????on;
????????#keepalive_timeout??0;
????????keepalive_timeout??65;
????????gzip??on;
????????server?{
????????????????listen?????????80;
????????????????servername?????;
????????????????access_log??????/var/log/nginx/access.log?main;
????????????????server_name_in_redirect??off;
????????????????location?/?{
????????????????????????root??/usr/share/nginx/html;
????????????????????????index?index.html;
????????????????}
????????}
????#?包含所有的虚拟主机的配置文件
????include?/usr/local/etc/nginx/vhosts/*;
}

5、重启 Nginx
/etc/init.d/nginx?restart
