篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了Resin+Nginx动静分离和负载均衡相关的知识,希望对你有一定的参考价值。
案例:目前很多人喜欢nginx+tomcat动静分离,或者反代后端tomcat集群,不过很多人也喜欢用Resin。
本人花了些功夫总结了Resin和tomcat区别:
特性\容器 | resin | tomcat |
公司 | CAUCHO | Apache |
是否收费 | 不完全免费(pro版本收费) | 完全免费 |
Eclipse下调试开发 | 适中 | 复杂 |
性能 | 轻量级,pro版本支持负载均衡,以及缓存功能 | 轻量级(NIO模式性能高些),支持负载均衡 |
多实例 | 略麻烦 | 比较简单 |
集群部署 | 支持 | 支持 |
是否支持php | 新版本支持(但很少用) | 默认不支持(可配置) |
用户喜好 | 略少 | 略多 |
常用组合 | Nginx+Resin or+其它 | Nginx+tomcat+or其它 |
报错机制 | 简单 | 复杂 |
标准|开发|行为喜好 | 两者在标准支持,开发使用,用户喜好有很大关系 |
常用JavaEE容器有很多:Tomcat、Resin、JBoss、Glassfish ,注意weblogic属于应用服务器。
1、安装配置Resin:
1.1)jdk目录创建:
[[email protected] ~]# tar zxvfjdk-7u75-linux-x64.tar.gz [[email protected] ~]# mkdir/usr/local/jdk1.7 [[email protected] ~]# mvjdk1.7.0_75/* /usr/local/jdk1.7/ [[email protected] ~]# cat/etc/profile.d/jdk.sh export JAVA_HOME=/usr/local/jdk1.7/ exportCLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar exportPATH=$PATH:$JAVA_HOME/bin export JAVA_HOMECLASSPATH PATH [[email protected] ~]#
1.2)Resin安装配置:
[[email protected] ~]# yum install ntpdate -y [[email protected]~]# ntpdate time.windows.com安装resin [[email protected]~]# tar xf resin-4.0.50.tar.gz -C /usr/local/ [[email protected]~]# cd /usr/local [[email protected]~]# #./configure --prefix=/usr/local/resin [[email protected]~]# #make [[email protected] ~]# #make install [[email protected] local]# ln -s resin-4.0.50 resin [[email protected] local]#cat / etc/profile.d/resin.sh exportRESIN_HOME=/usr/local/resin [[email protected] local]# [[email protected] local]#cp /usr/local/resin/bin/resin.sh /etc/init.d/resin [[email protected] local]#chmod +x /etc/init.d/resin [[email protected] local]#/etc/init.d/resin start
1.3)首页访问:
1.4)配置多个项目:
[[email protected] ~]# cd /usr/local/resin/conf [[email protected] conf]# vim resin.xml #配置多个项目: <clusterid="app1"> <!-- define the servers in the cluster --> <server-multiid-prefix="app1"address-list="${app1_servers}"port="6800"/> //端口1 <!-- the default host, matching any host name --> <hostid=""root-directory="."> <web-appid="/"root-directory="/usr/local/resin/webapps/app1"/> //项目1 </host> </cluster> <clusterid="app2"> <!-- define the servers in the cluster --> <server-multiid-prefix="app2"address-list="${app2_servers}"port="6801"/> //端口2 <!-- the default host, matching any host name --> <hostid=""root-directory="."> <web-appid="/"root-directory="/usr/local/resin/webapps/app2"/> //项目2 </host> </cluster>
1.4.1)定义端口:
# app-tier Triad servers: app-0 app-1 app-2 app1_servers : 127.0.0.1:6800 app2_servers : 127.0.0.1:6801 app1.http : 8080 app2.http : 8081
1.5)JDBC配置:
<database> <jndi-name>jdbc/test</jndi-name> <driver type="com.microsoft.jdbc.sqlserver.SQLServerDriver"> <url>jdbc:microsoft:sqlserver://localhost:3306;databasename=Northwind</url> //后端数据库 <user>sa</user> <password>password</password> //密码 </driver> <prepared-statement-cache-size>8</prepared-statement-cache-size> <max-connections>20</max-connections> <max-idle-time>30s</max-idle-time> </database>
注意:jdbc文件可自己定义,需要导入相应的驱动包。
2、安装配置Nginx:
useradd nginx -M -s /sbin/nologin tar xf nginx-1.9.2.tar.gz cd nginx-1.9.2 ./configure --user=nginx --group=nginx --prefix=/usr/local/nginx --with-http_stub_status_module--with-http_ssl_module --with-http_realip_module --with-http_flv_module --with-http_mp4_module --with-http_gzip_static_module&&make &&make install
2.1)nginx.conf配置负载均衡:
user nginx; worker_processes 8; #worker_cpu_affinity 00000001 00000010 00000100 00001000 00010000 00100000 01000000 10000000; error_log logs/error.log info; pid /var/run/nginx.pid; events { use epoll; worker_connections 1024; } http { include mime.types; default_type application/octet-stream; charset UTF-8; server_names_hash_bucket_size 128; client_header_buffer_size 32k; large_client_header_buffers 4 32k; client_max_body_size 8m; #limit_conn_zone $binary_remote_addr zone=one:32k; #limit_conn_zone $binary_remote_addr zone=permitip:10m; error_page 404 = http://www.jb51.net/404.html; #error_page 404 = /40x.html; #location = /40x.html{ #root html; #} #error_page 500 502 503 504 /50x.html; #location = /50x.html { #root html; #} open_file_cache max=102400 inactive=20s; sendfile on; #autoindex on; tcp_nopush on; tcp_nodelay on; keepalive_timeout 60; gzip on; gzip_min_length 1k; gzip_buffers 4 16k; gzip_http_version 1.0; gzip_comp_level 2; #gzip_types text/plain application/x-javascript text/css application/xml; gzip_vary on; fastcgi_connect_timeout 300; fastcgi_send_timeout 300; fastcgi_read_timeout 300; fastcgi_buffer_size 64k; fastcgi_buffers 4 64k; fastcgi_busy_buffers_size 128k; fastcgi_temp_file_write_size 128k; #如果要启用负载均衡 #upstream www.xxx.com { #zone myapp1 64k; #server 192.168.1.220:80 weight=1 max_fails=2 fail_timeout=30s slow_start=30s; #server 192.168.1.221:80 weight=1 max_fails=2 fail_timeout=30s; #} #upstream www.xxx.org { #zone myapp1 64k; #server 192.168.1.220:80 weight=1 max_fails=2 fail_timeout=30s slow_start=30s; #server 192.168.1.221:80 weight=1 max_fails=2 fail_timeout=30s; #} log_format access ‘$remote_addr - $remote_user [$time_local] $request $status $body_bytes_sent $http_referer $http_user_agent $http_x_forwarded_for‘; #access_log logs/access.log access; include vhost/*.conf; }
2.2)renzhiyuan.conf配置动静分离:
server { listen 80; server_name #路径根据 Resin定义路径配置,这里根据默认 root /usr/local/resin/webapps/ROOT; index index.html index.php index.jsp index.html; #location ~ \.php$ { # root html; # fastcgi_pass 127.0.0.1:9000; # fastcgi_index index.php; # include fastcgi.conf; # } location ~ .(jsp|jspx|do)?$ { proxy_set_header Host $host; proxy_pass http://127.0.0.1:8080; proxy_redirect off; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; client_max_body_size 10m; client_body_buffer_size 128k; proxy_connect_timeout 90; proxy_send_timeout 90; proxy_read_timeout 90; proxy_buffer_size 4k; proxy_buffers 4 32k; proxy_busy_buffers_size 64k; proxy_temp_file_write_size 64k; } location ~ .*\.(htm|html|gif|jpg|jpeg|png|bmp|swf|ioc|rar|zip|txt|flv|mid|doc|ppt|pdf|xls|mp3|wma)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 12h; } }
