Nginx+Tomcat负载均衡、动静分离
??? 一、负载均衡+动静分离
??? 修改nginx/conf/nginx.conf，修改完后如下：
#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; #设定请求缓冲 server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 300m; sendfile on; tcp_nopush on; keepalive_timeout 60; tcp_nodelay on; server_tokens off; client_body_buffer_size 512k; proxy_connect_timeout 5; proxy_send_timeout 60; proxy_read_timeout 5; proxy_buffer_size 16k; proxy_buffers 4 64k; proxy_busy_buffers_size 128k; proxy_temp_file_write_size 128k; client_header_timeout 3m; client_body_timeout 3m; send_timeout 3m; gzip on;#开启gzip，节省带宽 gzip_min_length 1100; gzip_buffers 4 8k; gzip_types text/plain text/css application/x-javascript image/bmp application/javascript; output_buffers 1 32k; postpone_output 1460; limit_rate_after 3m;#限速模块，前3M下载时不限速 limit_rate 512k; #限速模块 server { listen 80; server_name localhost; #charset koi8-r; access_log logs/host.access.log; #自动补全"/" if (-d $request_filename){ rewrite ^/(.*)([^/])$ http://$host/$1$2/ last; } ###################动静分离配置####################### ###################动态访问转向tomcat处理####################### #location ~ \.(jsp|page|do)?$ { # proxy_set_header Host $host; # proxy_set_header X-Real-IP $remote_addr; # proxy_pass http://mcul;#mcul与负载均衡upstream配置名称mcul一致 #} ###################设定访问静态文件直接读取不经过tomcat######### #location ~ .*\.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma)$ { # expires 30d; #} #location ~ .*\.(js|css)?$ { # expires 1h; #} ####################所有请求均有Tomcat处理############ location / { root html; index index.html index.htm; proxy_pass http://mcul; #mcul与负载均衡upstream配置名称mcul一致 } ###################动静分离配置####################### ##################404错误页################# error_page 404 /404.html; location = /40x.html { root html; } ##################404错误页################# # redirect server error pages to the static page /50x.html # ##################50x错误页################# error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } ##################50x错误页################# # 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; # } #} ############负载均衡配置########### upstream mcul { server 127.0.0.1:8080 weight=1; server 127.0.0.1:9080 weight=2; } ############负载均衡配置########### # 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; # } #}}???? 二、Session复制
??? 1.修改Tomcat/conf/server.xml, 在<Engine name=<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="6"> <Manager className="org.apache.catalina.ha.session.BackupManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true" mapSendOptions="6"/> <!-- <Manager className="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/> --> <Channel className="org.apache.catalina.tribes.group.GroupChannel"> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="auto" port="5000" selectorTimeout="100" maxThreads="6"/> <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter"> <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> </Sender> <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector"/> <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15Interceptor"/> <Interceptor className="org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor"/> </Channel> <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=".*\.gif|.*\.js|.*\.jpeg|.*\.jpg|.*\.png|.*\.htm|.*\.html|.*\.css|.*\.txt"/> <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/> </Cluster>
