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
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.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver1/resinserver1/ shell $> make shell $> 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 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"> <!--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 ../bin shell $>./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.gz shell $> cd resin-4.0.23 shell $> ./configure --prefix=/usr/resin/resinserver2/resinserver2/ shell $> make shell $> 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 ../bin shell $>./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-1.1.5 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
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; #error_log logs/error.log notice; #error_log logs/error.log info; pid logs/nginx.pid; events { worker_connections 1024;#每个工作进程允许最大的同时连接数 } http { upstream backend {#集群服务器 server 127.0.0.1:8080 srun_id=resinserver1; server 127.0.0.1:8081 srun_id=resinserver2; jvm_route $cookie_JSESSIONID|sessionid;#session共享 } include mime.types;#内定义各文件类型映像,也可使用 default_type application/octet-stream;#设置默认类型是二进制流 #log_format main '$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; sendfile on; #tcp_nopush on; #keepalive_timeout 0; keepalive_timeout 65; #gzip on;#打开gzip文件压缩 server { listen 80; server_name localhost; charset UTF-8; #下面为location的配置,可以根据自己的业务情况进行定制 #access_log logs/host.access.log main; location / { root html; index index.html index.htm; } #error_page 404 /404.html; # redirect server error pages to the static page /50x.html # error_page 500 502 503 504 /50x.html; location = /50x.html { root html; } location ~ .*\.jsp$ { proxy_pass http://backend; proxy_redirect off; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $http_host; } location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$ { expires 30d; } location ~ .*\.(js|css)?$ { expires 1h; } # 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; # } #} # 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; # } #} }
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
参考文章自我总结:
1,下面这个端口号也要变,不然只能启动一个resin实例(未解)
<!-- SSL port configuration: -->
<http address="*" port="8444">
<jsse-ssl self-signed-certificate-name="resin@localhost"/>
</http>
2,上面那两个软件windows中不能安装,会报异常,改成以下配置,
upstream backend {
server 127.0.0.1:8080 ;
server 127.0.0.1:8081;
}
nginx_upstream_jvm_route 是一个
Nginx 的扩展模块,用来实现基于 Cookie 的 Session Sticky 的功能。
session replication 策略是复制会话,即一个用户访问了一次就把session复制到所有的服务器或这一部分服务器。
这样的好处是如果正访问的服务器down了 用户可以自动被转到别的服务器session不丢失。缺点当然是效率低。
session sticky策略则是不复制,一个用户访问了一次后,同一个session周期内,所有的请求都定向到这个服务器,
down了session就丢了。
3,启动不同服务名称的resin实例时,要到命令行去,不然不知道启动哪个,报异常。
到G:\javaWeb\resin-pro-2\bin\目录:
start.bat -server resinserver2 start
