http://nginx.org/download/nginx-1.6.2.tar.gz


tar xvzf nginx-1.6.2.tar.gz 

cd nginx-1.6.2

./configure --prefix=/Users/dugang/apps/nginx --with-http_stub_status_module

make

make install


/Users/dugang/apps/nginx/conf/nginx.conf


/Users/dugang/apps/nginx/sbin
启动
./nginx 

nginx: [emerg] bind() to 0.0.0.0:80 failed (13: Permission denied)

80端口需要使用 sudo  

sudo ./nginx 

端口被占用会报错
nginx: [emerg] bind() to 0.0.0.0:80 failed (48: Address already in use)

验证配置文件是否正确
nginx -t  
重启
nignx -s reload


本地启动三个tomcat 实例，端口分别为 7000 7001 7002
用于配置负载均衡

http 节点下 增加

upstream backendServers {
        server 127.0.0.1:7000;
        server 127.0.0.1:7001;
        server 127.0.0.1:7002;
}

server节点 下 配置 

location / {
            proxy_pass http://backendServers;
}
        
        

nginx.conf  配置文件信息



worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    
    upstream backendServers {
        server 127.0.0.1:7000;
        server 127.0.0.1:7001;
        server 127.0.0.1:7002;
    }

    server {
        listen       80;
        server_name  localhost;
        location / {
            proxy_pass http://backendServers;
        }
    }
}
