Resin+Nginx实现动静分离和负载均衡

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:

[root@resin ~]# tar zxvfjdk-7u75-linux-x64.tar.gz
[root@resin ~]# mkdir/usr/local/jdk1.7
[root@resin ~]# mvjdk1.7.0_75/* /usr/local/jdk1.7/
[root@resin ~]# 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
[root@resin ~]#

1.2)Resin安装配置:

[root@resin ~]# yum install ntpdate -y
[root@resin~]# ntpdate time.windows.com安装resin
[root@resin~]# tar xf resin-4.0.50.tar.gz -C /usr/local/
[root@resin~]# cd /usr/local
[root@resin~]# #./configure --prefix=/usr/local/resin
[root@resin~]# #make
[root@resin ~]# #make install
[root@resin local]# ln -s resin-4.0.50 resin
[root@resin local]#cat / etc/profile.d/resin.sh
exportRESIN_HOME=/usr/local/resin
[root@resin local]#
[root@resin local]#cp /usr/local/resin/bin/resin.sh /etc/init.d/resin
[root@resin local]#chmod +x /etc/init.d/resin
[root@resin local]#/etc/init.d/resin start

1.4)配置多个项目:

[root@resin ~]# cd /usr/local/resin/conf
[root@resin 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.linuxidc.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;
}
}
