Nginx+tomcat Distributed Deployment

Configuration files that need to be changed:

1. Hosts file

2, the server.xml of each tomcat

3, nginx configuration file nginx.conf

Configure two tomcat as a single machine (configure multiple machines as long as the corresponding IP address is changed to the IP address of the cluster machine)

The first step is to configure the Hosts file

Win7 under: C:\Windows\System32\drivers\etc\hosts

Append at the very end: Host IP domain name

The second step, the Tomcat configuration file, if on the same machine to pay attention to modify the port number, if the deployment on a different machine on the same port number is not related

Other Tomcat configurations above (same machine note port number)

Step three, configure Nginx

Worker_processes 2;


#error_log Logs/error.log;
#error_log Logs/error.log Notice;
#error_log Logs/error.log Info;


#pid Logs/nginx.pid;



Events {
Worker_connections 65535;
}




HTTP {
Client_max_body_size 100m;
Include Mime.types;
Default_type Application/octet-stream;


Sendfile on;
Tcp_nopush on;


Keepalive_timeout 60;


# gzip on;

Include vhosts_tomcat/*.conf;


Upstream myserver{
IP of server tomcat1: Port weight=2;
IP of server tomcat2: Port weight=3;
}
server{
Listen 80;
server_name domain name;


Location/{

Index index.html index.htm index.jsp;
Proxy_pass http://MyServer;
#proxy_read_timeout 1800;
#proxy_send_timeout 1800;
#该指令用来设置分配到后端服务器的连接超时时间
#proxy_connect_timeout 300;


# #cache # #
Proxy_connect_timeout 50;
Proxy_read_timeout 120;
Proxy_send_timeout 120;
Proxy_buffer_size 16k;
Proxy_buffers 4 64k;

Proxy_busy_buffers_size 128k;
Proxy_temp_file_write_size 128k;


# support WebSocket below is the key
Proxy_http_version 1.1;
Proxy_set_header Upgrade $http _upgrade;
Proxy_set_header Connection "Upgrade";
# This is the problem of configuring Webpysessoin loss

}
}
}

Fourth step, start each tomcat in turn, start Nginx

Enjoy youself.
