本文介绍配置Nginx+tomcat服务器环境和负载均衡，希望对于初学Nginx服务器相关的朋友有帮助，更多Nginx安装、配置、报错处理等资源请本站内搜索。。
1、安装nginx 和JDK
# cd /usr/ports/www/nginx && make install clean
# cd /usr/ports/java/jdk16 && make install clean
这里会报错

#cd /usr/ports/java/jdk16 && make install clean
2、配置环境
3、安装tomcat
# /usr/ports/www/tomcat6 && make install
#echo 'tomcat60_enable="YES"' >> /etc/rc.conf
#/usr/local/etc/rc.d/tomcat6 start
配置端口
#vim /usr/local/apache-tomcat-6.0/conf/server.xml
omcat的配置可以通过两种方式来配置。
1.通过/conf/server.xml来配置。
2.通过可视化的界面来配置。
下面来介绍server.xml的配置：
按装完Tomcat后它的server.xml的配置内容是这样的：
connectionTimeout="2000"
它表式的是：一个客房端连接到服务器如果没有任何动作它如果超过这个时间那么它就视为无效。
2000表式的是毫秒。
maxThreads="150"
它表示的是同一时间连接到服务器上的同一个页面时的最大连接数。
里面有三个端口配置
<Connector port="8180" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
在 <Host> 和 </Host> 之间加入
<Context path="/myapp" docBase="/data/vhosts/www.example.com" debug="0" reloadable="true" crossContext="true" />
二、配置
1、nginx.conf添加tomcat反向代理
#vim /usr/local/etc/nginx/nginx.conf
upstream tomcat_server{
server 127.0.0.1:8180;
}
2、站点配置文件使用反向代理。
#vim /usr/local/etc/nginx/vhosts/www.example.com.conf
添加
location ~ .*.(gif|jpg|jpeg|png|bmp|swf)$ {
root /data/vhosts/www.example.com;
}
location ~ .*.(jsp|do)$ {
proxy_pass http://tomcat_server;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
#nginx -t
三、测试
#/usr/local/etc/rc.d/nginx reload
#ee /data/vhosts/www.example.com/test.jsp
<HTML>
<HEAD>
<TITLE>JSP测试页面</TITLE>
</HEAD>
<BODY>
<%out.println("<h1>Hello World! </h1>");%>
</BODY>
</HTML>
#cp ~diege/test.jpg /data/vhosts/www.example.com/
访问测试
0101 Firefox/11.0"
172.17.2.160 - - [25/Apr/2012:14:59:10 +0800] "GET /test.jsp HTTP/1.1" 404 979 "-" "Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0"
cp /data/vhosts/www.example.com/test.jsp /usr/local/apache-tomcat-6.0/work/Catalina/www.example.com/
不行
cp /data/vhosts/www.example.com/test.jsp /usr/local/apache-tomcat-6.0/webapps/ROOT/
172.17.2.160 - - [25/Apr/2012:15:14:10 +0800] "GET /test.jsp HTTP/1.1" 200 101 "-" "Mozilla/5.0 (Windows NT 5.1; rv:11.0) Gecko/20100101 Firefox/11.0"
新定义一个端口和站点
四、多个tomcat构建负载均衡
#vim /usr/local/etc/nginx/nginx.conf
upstream tomcat_server{
server 192.168.1.100:8080;
server 192.168.1.110:8080;
server 192.168.1.120:8080;
}
