Nginx Tomcat 集群负载均衡设置笔记

1、Windows

下载nginx 地址:http://nginx.org/ 本文章使用的版本为1.5.4

下载完后解压,在conf目录修改nginx.conf我的配置如下:

#user nobody;
worker_processes 1;
#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;
#pid logs/nginx.pid;

events {
worker_connections 1024;
}

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;

client_header_timeout 3m;
client_body_timeout 3m;
send_timeout 3m;

client_header_buffer_size 1k;
large_client_header_buffers 4 4k;
sendfile on;
tcp_nopush on;
tcp_nodelay on;
#tcp_nopush on;

#keepalive_timeout 0;
keepalive_timeout 65;
#gzip on;
upstream localhost {
#根据ip计算将请求分配各那个后端tomcat,许多人误认为可以解决session问题,其实并不能。
#同一机器在多网情况下,路由切换,ip可能不同
#ip_hash;
server localhost:9097 weight=1;
server localhost:9098 weight=1;
server localhost:9097 backup;
server localhost:9098 backup;
#jvm_route $cookie_JSESSIONID|sessionid reverse; #session复制的配置
ip_hash;
}

upstream backend {
server localhost:9097;
server localhost:9098;
}
server {
listen 9096;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location ~ ^/(WEB-INF)/ {
deny all;
}

###所以的静态文件人gif、jpg等都在本地打开,存放的目录为html,保存时间为30天
location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|css|js|htm|html)$ {
root html;
access_log off;
expires 30d;
}
location / {
root html;
index index.jsp;
#include proxy.conf; #这个文件是我们新建的,要导入
proxy_pass http://localhost;
proxy_redirect off;#default
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
client_max_body_size 10m;
client_body_buffer_size 128k;
proxy_connect_timeout 3; #90
proxy_send_timeout 3; #90
proxy_read_timeout 3; #90
proxy_buffer_size 4k;
proxy_buffers 4 32k;
proxy_busy_buffers_size 64k;
proxy_temp_file_write_size 64k;
}
#error_page 404 /404.html;
# redirect server error pages to the static page /50x.html
#
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}
# proxy the PHP scripts to Apache listening on 127.0.0.1:80
#
#location ~ \.php$ {
# proxy_pass http://127.0.0.1;
#}
# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
#location ~ \.php$ {
# root html;
# fastcgi_pass 127.0.0.1:9000;
# fastcgi_index index.php;
# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;
# include fastcgi_params;
#}
# deny access to .htaccess files, if Apache’s document root
# concurs with nginx’s one
#
#location ~ /\.ht {
# deny all;
#}
}

# another virtual host using mix of IP-, name-, and port-based configuration
#
#server {
# listen 8000;
# listen somename:8080;
# server_name somename alias another.alias;
# location / {
# root html;
# index index.html index.htm;
# }
#}

# HTTPS server
#
#server {
# listen 443;
# server_name localhost;
# ssl on;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_timeout 5m;
# ssl_protocols SSLv2 SSLv3 TLSv1;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}

下载Tomcat

修改端口为9097

另一个修改为9098

分别启动二个tomcat和nginx在地址栏中输入http://locahost/则可以看到tomcat欢迎界面

Linux 和window配置基本一样,只有linux下tomcat的配置要注意,需要添加环境变量
