本机配置好两个tomcat：
# curl http://127.0.0.1:8080 Tomcat 1 test jsp # curl http://127.0.0.1:8081 Tomcat 2 test jsp
配置本地hosts文件：
# cat /etc/hosts 127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 127.0.0.1 tomcat1.com tomcat2.com
配置Nginx：
# cat nginx.conf
#user nobody;
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
include conf.d/vhost.conf;
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"';
#记录用户访问的真实IP
#log_format main '$HTTP_X_REAL_IP - $remote_user [$time_local] "$request" '
# '$status $body_bytes_sent "$http_referer" '
# '"$http_user_agent" "$http_x_forwarded_for"';
#access_log logs/access.log main;
sendfile on;
tcp_nopush on;
keepalive_timeout 65;
gzip on;
client_max_body_size 50m; #缓冲区代理缓冲用户端请求的最大字节数,可以理解为保存到本地再传给用户
client_body_buffer_size 256k;
client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;
proxy_connect_timeout 300s; #nginx跟后端服务器连接超时时间(代理连接超时)
proxy_read_timeout 300s; #连接成功后，后端服务器响应时间(代理接收超时)
proxy_send_timeout 300s;
proxy_buffer_size 64k; #设置代理服务器（nginx）保存用户头信息的缓冲区大小
proxy_buffers 4 32k; #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置
proxy_busy_buffers_size 64k; #高负荷下缓冲大小（proxy_buffers*2）
proxy_temp_file_write_size 64k; #设定缓存文件夹大小，大于这个值，将从upstream服务器传递请求，而不缓冲到磁盘
proxy_ignore_client_abort on; #不允许代理端主动关闭连接
server {
listen 80;
server_name localhost;
location / {
root html;
index index.html index.htm;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
}
}配置反向代理配置文件：
# cat conf.d/vhost.conf
server
{
listen 80;
server_name tomcat1.com;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8080;
}
access_log logs/tomcat1_access.log;
}
server
{
listen 80;
server_name tomcat2.com;
location / {
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_pass http://127.0.0.1:8081;
}
access_log logs/tomcat2_access.log;
}重新加载配置文件：
# /opt/nginx/sbin/nginx -s reload
测试：
# curl http://tomcat1.com Tomcat 1 test jsp # curl http://tomcat2.com Tomcat 2 test jsp
