配置nginx相同端口多站点，首先我们要配置环境，这里用的是lnmp一键安装包，用一键安装包的方法后续再写，先看看安装之后的，我们浏览一下安装完成页面，
这个是默认环境页面，可以在配置文件里看到，
根据上图可以看出默认路径是/home/wwwroot/default，这是个默认的配置文件，我们可以把这个默认的配置文件拷贝到vhost目录下/usr/local/nginx/conf/vhost/,拷贝之后我们需要修改一下默认配置文件，编辑nginx.conf，在最低端include后面的改成/usr/local/nginx/conf/vhost/*.conf;，看看正确的编辑。
[root@Python ~]# vi /usr/local/nginx/conf/nginx.conf gzip_disable "MSIE [1-6]\."; #limit_conn_zone $binary_remote_addr zone=perip:10m; ##If enable limit_conn_zone,add "limit_conn perip 10;" to server section. server_tokens off; #log format log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log off;server { listen 80; #listen [::]:80 default_server ipv6only=on; server_name www.lnmp.org; index index.html index.htm index.php; root /home/wwwroot/default; #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; server_name www.lnmp.org; index index.html index.htm index.php; root /home/wwwroot/default; #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } location ~ /\. { deny all; } access_log /home/wwwlogs/access.log access; }include /usr/local/nginx/conf/vhost/*.conf;} 然后就是在vhost目录下修改我们使用的站点了，把拷贝过来的站点复制一份，并修改不同的名称，这里我们用两个域名www.aa.com、www.bb.com为了区分我们就用aa.com.conf、bb.com.conf命名，我们需要把一些不要的内容删除掉，也可以先修改后复制命名，比较省事。就以aa.com.conf为例：
[root@Python vhost]# vi aa.com.conf#user www www; #删除worker_processes auto; #删除error_log /home/wwwlogs/nginx_error.log crit;pid /usr/local/nginx/logs/nginx.pid; #删除#Specifies the value for maximum file descriptors that can be opened by this process.worker_rlimit_nofile 51200; #删除events #删除 { use epoll; worker_connections 51200; multi_accept on; }http #删除 { include mime.types; default_type application/octet-stream; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 50m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 256k; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.1; gzip_comp_level 2; gzip_types text/plain application/javascript application/x-javascript text/javascript text/css application/xml application/xml+rss; gzip_vary on; gzip_proxied expired no-cache no-store private auth; gzip_disable "MSIE [1-6]\."; #limit_conn_zone $binary_remote_addr zone=perip:10m; ##If enable limit_conn_zone,add "limit_conn perip 10;" to server section. server_tokens off; #log format log_format access '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" $http_x_forwarded_for'; access_log off; 以上信息在aa.com.conf和bb.com.conf文件里都需要删除部分还有就是在低端的include也要删除，并且为了区分我们上传一个论坛使用两个域名访问两个不同的目录，一个是默认的lnmp目录，一个是网站目录，www.aa.com使用默认目录配置如下：
[root@Python vhost]# vi aa.com.conf error_log /home/wwwlogs/nginx_error.log crit;#Specifies the value for maximum file descriptors that can be opened by this process.server { listen 80; #端口 #listen [::]:80 default_server ipv6only=on; server_name www.aa.com; #域名 index index.html index.htm index.php; root /home/wwwroot/default; #访问跟目录 #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on;error_log /home/wwwlogs/nginx_error.log crit;#Specifies the value for maximum file descriptors that can be opened by this process.server { listen 80; #listen [::]:80 default_server ipv6only=on; server_name www.aa.com; index index.html index.htm index.php; root /home/wwwroot/default; #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ listen 80; #listen [::]:80 default_server ipv6only=on; server_name www.aa.com; index index.html index.htm index.php; root /home/wwwroot/default; #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } location ~ /\. { deny all; } access_log /home/wwwlogs/access.log access; } 域名bb.com.conf配置
[root@Python vhost]# vi bb.com.conf error_log /home/wwwlogs/nginx_error.log crit;#Specifies the value for maximum file descriptors that can be opened by this process.server { listen 80; #端口 #listen [::]:80 default_server ipv6only=on; server_name www.bb.com; #域名 index index.html index.htm index.php; root /home/wwwroot/upload; #网站根目录 #error_page 404 /404.html; include enable-php.conf; location /nginx_status { stub_status on; access_log off; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } location ~ /\. { deny all; } access_log /home/wwwlogs/access.log access; } 配置好之后我们就测试一下，用另外一台电脑，在hosts文件里把两个域名指定到一个IP上，
[root@localhost ~]# vi /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4::1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.170.134 www.aa.com192.168.170.134 www.bb.com
下面就测试一下两个域名所浏览的页面
aa.com.conf配置的页面
bb.com.conf页面配置
测试完成。
