tomcat利用nginux进行负载均衡-爱代码爱编程
1、下载nginx,http://nginx.org/en/download.html
2、解压后双击nginx.exe文件或通过cmd进入解压目录执行nginx.exe启动服务,关闭服务需要通过cmd进入解压目录执行nginx -s stop,启动后访问localhost可以进入欢迎页。
3、复制3个tomcat,分别命名tomcat_1、tomcat_2、tomgcat_3,将各自端口进行修改为8080、8081、8082。
4、在nginx目录的conf中修改nginx.conf文件。
#user nobody;
worker_processes 4; # 工作进程的个数,一般与计算机的cpu核数一致
#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; # 单个进程最大连接数(最大连接数 = 连接数 * 进程数)
}
http {
include mime.types; # 文件扩展名与文件类型映射表
default_type application/octet-stream; # 默认文件类型
#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; # 开启高效文件传输模式,sendfile指令指定nginx是否调用sendfile函数来输出文件,对于普通应用设为on,如果用来进行下载等应用磁盘IO重负载应用,可设置为off,以平衡磁盘与网络I/O处理速度,降低系统的负载。注意:如果图片显示不正常把这个改成off。
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65; # 长连接超时时间,单位是秒
#gzip on; # 启用Gizp压缩
#服务器的集群
upstream zsq { # 服务器集群名字
server 127.0.0.1:8080 weight=1; # 服务器配置 weight是权重的意思,权重越大,分配的概率越大。
server 127.0.0.1:8081 weight=2;
server 127.0.0.1:8082 weight=3;
}
# 当前的Nginx的配置
server {
listen 80; # 监听80端口,可以改成其他端口
server_name localhost; # 当前服务的域名
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
# root html;
# index index.html index.htm;
proxy_pass http://zsq;# 访问地址
proxy_redirect default;
}
#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 ssl;
# server_name localhost;
# ssl_certificate cert.pem;
# ssl_certificate_key cert.key;
# ssl_session_cache shared:SSL:1m;
# ssl_session_timeout 5m;
# ssl_ciphers HIGH:!aNULL:!MD5;
# ssl_prefer_server_ciphers on;
# location / {
# root html;
# index index.html index.htm;
# }
#}
}
4、分别启动三个tomcat,最后启动nginx,访问http://localhost,会随机进入到8080/8081/8082中。
