1、Nginx+Tomcat+Redis实现负载均衡、资源分离、session共享CentOS安装Nginxhttp:/ mytomcats server 192.168.1.177:8001; server 192.168.1.177:8002; server 192.168.1.177:8003; server listen 80; server_name ; location * .(jpg|gif|png|swf|flv|wma|wmv|asf|mp3|mmf|zip|rar)$ root /web/www/html/; location / proxy_pass http:/mytomc
2、ats; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_siz
3、e 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; upstream指定负载均衡组，指定其Tomcat成员location * .(jpg|gif|实现了静态资源分离。ps：在location指令使用正则表达式后再用alias指令，Nginx是不支持的。2、Nginx实现静态资源分离Tomcat服务192.168.1.177:8000Nginx配置server listen 80; server_name ; root /web/www/html; location /i
4、mg/ alias /web/www/html/img/; location (.jsp)|(.do)$ proxy_pass http:/192.168.1.177:8000; proxy_redirect off; 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; pro
5、xy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; 第一个location指令将/web/www/html/img/目录下的静态文件交给Nginx来完成。最后一个location指令将所有以.jsp、.do结尾的文件都交给Tomcat服务器的8080端口来处理。3、Nginx+Tomcat+Redis实现
6、session共享Redis服务192.168.1.178:6379Tomcat服务192.168.1.177:8001192.168.1.177:8002192.168.1.177:8003Nginx服务192.168.1.179配置Tomcat让其session保存到redis上，在context.xml配置(Value标签一定要在Manager标签前面)：配置Nginxupstream mytomcats server 192.168.1.177:8001; server 192.168.1.177:8002; server 192.168.1.177:8003; log_format
7、www_iu14_com $remote_addr - $remote_user $time_local $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for; server listen 80; server_name ; location / proxy_pass http:/ mytomcats; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; access_log /usr/tmp/logs/redis.iu14.log www_iu14_com; 依次启动Redis、Tomcat、Nginx，访问Nginx
