测试
三台服务整合，修改nginx配置文件，配置负载均衡和反向代理
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"';
#access_log logs/access.log main;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
#新增下面4行，配置负载均衡
upstream web.com {
server 192.168.118.222:8080;
server 192.168.118.222:8081;
}
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
#新增下面3行 添加反向代理location
location ~* .(jsp|do)$ {
proxy_pass http://web.com;
}
location / {
root html;
index index.html index.htm;
}
重启nginx
测试
刷新一下，为tomcat2测试页
