需求：同一主機上跑多個web站點，使用httpd+php-fpm無法滿足需要；
解決方案：加一個nginx，接入所有用戶訪問，根據用戶訪問的主頁不同，反代後端不同站點；
前端：nginx
後端：
同一主機多個web站點
new.khcm.net
安裝過程略，主要描述反代過程：
nginx主配置文件：
]# egrep -v '^[[:space:]]*#|^$' /etc/nginx/nginx.conf
user nginx;
worker_processes auto;
error_log /var/log/nginx/error.log;
pid /run/nginx.pid;
include /usr/share/nginx/modules/*.conf;
events {
worker_connections 1024;
}
http {
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
access_log /var/log/nginx/access.log main;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
include /etc/nginx/conf.d/*.conf;
server {
listen 80 default_server;
listen [::]:80 default_server;
server_name _;
root /usr/share/nginx/html;
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
}
採用每個站點一個配置文件，放在/etc/nginx/conf.d/目錄下：
www.bbtw.net站點，配置文件爲bbt.conf；
www.shxinsheng.wang站點，配置文件爲xyk.conf；
new.khcm.net站點，配置文件爲khcm.conf
]# cat /etc/nginx/conf.d/bbt.conf
server {
listen 80;
server_name www.bbtw.net;
port_in_redirect on;
keepalive_timeout 15;
location / {
proxy_set_header Connection '';

proxy_pass http://127.0.0.1:81$request_uri;
}
}
