ubuntu16.04+nginx+tomcat集群配置

 安装nginx

通过sudo apt-get install nginx安装，因为自己下载tar.gz文件安装的话，还需要解决包依赖关系。
安装tomcat就不说了。
修改/etc/nginx/nginx.conf文件
如下
user www-data;
worker_processes auto;
pid /run/nginx.pid;

events {
worker_connections 768;
# multi_accept on;
}

http {

##
# Basic Settings
##

sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
# server_tokens off;

# server_names_hash_bucket_size 64;
# server_name_in_redirect off;

include /etc/nginx/mime.types;
default_type application/octet-stream;

##
# SSL Settings
##

ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;

##
# Logging Settings
##

access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;

##
# Gzip Settings
##

gzip on;
gzip_disable "msie6";

# gzip_vary on;
# gzip_proxied any;
# gzip_comp_level 6;
# gzip_buffers 16 8k;
# gzip_http_version 1.1;
# gzip_types text/plain text/css application/json application/javascript text/xml application/xml application/xml+rss text/javascript;

##
# Virtual Host Configs

##
##添加下面这段
upstream localhost {  
     #ip_hash  
      #ip_hash;  
      server localhost:8080;
      server localhost:8090;  
     }  
  
    server {
            listen       80;
            server_name  localhost;     
  
            location / {  
              proxy_connect_timeout   3;  
              proxy_send_timeout      30;  
              proxy_read_timeout      30;  
                proxy_pass http://localhost;               }  
              
   } 

##并将下面两句话注释
#include /etc/nginx/conf.d/*.conf;
#include /etc/nginx/sites-enabled/*;
}

#mail {
# # See sample authentication script at:
# # http://wiki.nginx.org/ImapAuthenticateWithApachePhpScript # 
# # auth_http localhost/auth.php;
# # pop3_capabilities "TOP" "USER";
# # imap_capabilities "IMAP4rev1" "UIDPLUS";
# 
# server {
# listen     localhost:110;
# protocol   pop3;
# proxy      on;
# }
# 
# server {
# listen     localhost:143;
# protocol   imap;
# proxy      on;
# }
#}
重启nginx 
/etc/init.d/nginx restart 

然后访问就可以直接进入tomcat的项目中啦！
