Nginx1.1实现Resin4集群
- 博客分类:
- Tomcat6
一,web服务器小论
以前的公司使用的web服务器是tomcat(tomcat+apache作集群),现在的公司是一家互联网公司,采用的架构是resin+nginx作集群(resin比tomcat快?还有待以后章节比较讨论),
集群配置服务器说明:
1),serve1:127.0.0.1:8080
2), serve2:127.0.0.1:8081
3), nginx:127.0.0.1:80
二,配置resin服务器
(注:resin4之前,可以搭一个服务器,在<cluster></cluster>中配置多个server实例,通过实例启动,4.0之后就不可以了,要有专业版才能实现)
在安装resin之前,必须先安装完jvm环境。
serve1:127.0.0.1:8080--->
1,安装resin-4.0.*.tar.gz包
- shell $> tar zxvf resin-4.0.23.tar.gz
- shell $> cd resin-4.0.23
- shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/
- shell $> make
- shell $> make install
shell $> tar zxvf resin-4.0.23.tar.gzshell $> cd resin-4.0.23shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/shell $> makeshell $> make install
2,配置resin.conf文件
shell $> cd /usr/resin/resinserver1/resinserver1/
- shell $> cd conf
- shell $> vim resin.conf
- ## 查找 <http address="*" port="8080"/>
- ## 注释掉 <!--http address="*" port="8080"/-->
- ## 查找 <server id="" address="127.0.0.1" port="6800">
- ## 替换成
- <server id="resinserver1" address="127.0.0.1" port="6800">
- <!--<STRONG>两台服务器配置不同的watchdog端口,否则会出现异常</STRONG>-->
- <watchdog-port>6700</watchdog-port>
- <http id="" port="8080"/>
- </server>
- ###重启 resin 服务#####
- shell $> cd ../bin
- shell $>./resin.sh -server resinserver1 start
shell $> cd confshell $> vim resin.conf## 查找 <http address="*" port="8080"/>## 注释掉 <!--http address="*" port="8080"/-->## 查找 <server id="" address="127.0.0.1" port="6800">## 替换成 <server id="resinserver1" address="127.0.0.1" port="6800"> <!--两台服务器配置不同的watchdog端口,否则会出现异常--> <watchdog-port>6700</watchdog-port> <http id="" port="8080"/> </server>###重启 resin 服务#####shell $> cd ../binshell $>./resin.sh -server resinserver1 start
serve1:127.0.0.1:8081--->
---1,
- shell $> tar zxvf resin-4.0.23.tar.gz
- shell $> cd resin-4.0.23
- shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/
- shell $> make
- shell $> make install
shell $> tar zxvf resin-4.0.23.tar.gzshell $> cd resin-4.0.23shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/shell $> makeshell $> make install
2,配置resin
shell $> cd conf
- shell $> vim resin.conf
- ## 查找 <http address="*" port="8080"/>
- ## 注释掉 <!--http address="*" port="8080"/-->
- ## 查找 <server id="" address="127.0.0.1" port="6800">
- ## 替换成
- <server id="resinserver2" address="127.0.0.1" port="6801">
- <!--两台服务器配置不同的watchdog端口-->
- <watchdog-port>6701</watchdog-port>
- <http id="" port="8081"/>
- </server>
- ###重启 resin 服务#####
- shell $> cd ../bin
- shell $>./resin.sh -server resinserver2 start
shell $> vim resin.conf## 查找 <http address="*" port="8080"/>## 注释掉 <!--http address="*" port="8080"/-->## 查找 <server id="" address="127.0.0.1" port="6800">## 替换成 <server id="resinserver2" address="127.0.0.1" port="6801"> <!--两台服务器配置不同的watchdog端口--> <watchdog-port>6701</watchdog-port> <http id="" port="8081"/> </server>###重启 resin 服务#####shell $> cd ../binshell $>./resin.sh -server resinserver2 start
通过以上配置,开启两台resin服务器,接下来就是配置nginx
三,nginx的配置
nginx安装需要以下软件包安装
1,nginx-1.1.5.tar.gz
2,tbje-nginx-upstream-jvm-route-6016b39.tar.gz
3,openssl-1.0.0e.tar.gz(OPENSSL不需要编译安装,只需要解压出来就行)
分别解压以上程序...
- shell $> cd nginx-1.1.5
- shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patch
- shell $> useradd www
- shell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39
- shell $> make
- shell $> make install
shell $> cd nginx-1.1.5shell $> patch -p0 < ../tbje-nginx-upstream-jvm-route-6016b39/jvm_route.patchshell $> useradd wwwshell $> ./configure --user=www --group=www --prefix=/usr/nginx/nginxserver --with-http_stub_status_module --with-http_ssl_module=/usr/nginx/openssl-1.0.0e --add-module=/usr/nginx/tbje-nginx-upstream-jvm-route-6016b39shell $> makeshell $> make install
到nginxserver/sbin目录下,,运行./nginx 访问http://127.0.0.1 出现“webcome to nginx”代表nginx安装成功
四,配置集群
打开nginxserver/conf/nginx.conf文件。
- user www www;#工作进程的属主
- worker_processes 2;#工作进程数,一般与 CPU 核数等同
- error_log logs/error.log crit;

nginx命令:
- start nginx 开启nginx
- Nginx -s stop 快速关闭Nginx,可能不保存相关信息,并迅速终止web服务。(quick exit)
- Nginx -s quit 平稳关闭Nginx,保存相关信息,有安排的结束web服务。(graceful exit)
- Nginx -s reload 因改变了Nginx相关配置,需要重新加载配置而重载。(changing configuration,start a new worker,quitting an old worker gracefully.)
- Nginx -s reopen 重新打开日志文件。(reopenging log files)

上面两resin的服务器已经打开,更改两服务器下的如(resinserver1):/usr/resin/resinserver1/resinserver1/webapps/ROOT 下的index.jsp
区别服务器访问路径:
- <%@page language="java" import="java.util.*" pageEncoding="UTF-8"%>
- <%
- %>
- <html>
- <head>
- </head>
- <body>
- nginxserver1<!--在另一台服务器上写nginxserver2-->
- <br />
- <%out.print(request.getSession()) ;%>
- <br />
- <%out.println(request.getHeader("Cookie")); %>
- </body>
- </html>
<%@page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% %> <html> <head> </head> <body> nginxserver1<!--在另一台服务器上写nginxserver2--> <br /> <%out.print(request.getSession()) ;%> <br /> <%out.println(request.getHeader("Cookie")); %> </body> </html>
这时重启nginx
这时访问:http://127.0.0.1/index.jsp会出现以下情况:
- 比较
- resinserver1----->
- nginxserver1
- SessionImpl[aaadbhbcljrab7wtdprmt,]
- JSESSIONID=aaadbhbcljrab7wtdprmt
- 或者
- resinserver2----->
- nginxserver2
- SessionImpl[aaadbhbcljrab7wtdprmt,]
- JSESSIONID=aaadbhbcljrab7wtdprmt
