tomcat与nginx的整合

一.安装Tomcat和jdk

1.安装jdk
# tar xvf jdk1.6.0_11.tar
# mv jdk1.6.0_11 /usr/local/
配置环境变量
# vim /etc/profile 添加
JAVA_HOME=/usr/local/jdk1.6.0_11
export JAVA_HOME
CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export CLASSPATH
PATH=$JAVA_HOME/bin:$PATH
export PATH

# sourse /etc/profile
# echo $JAVA_HOME
/usr/local/jdk1.6.0_11

2.安装tomcat
# tar zxvf apache-tomcat-6.0.29.tar.gz
# mv apache-tomcat-6.0.29 /usr/local/tomcat6

3.启动tomcat
# /usr/local/tomcat6/bin/startup.sh
Using CATALINA_BASE:   /usr/local/tomcat6
Using CATALINA_HOME:   /usr/local/tomcat6
Using CATALINA_TMPDIR: /usr/local/tomcat6/temp
Using JRE_HOME:       /usr/local/jdk1.6.0_11
# ps aux | grep tomcat
root     12717  0.5 12.3 220452 31588 pts/0    Sl   19:24   0:02 /usr/local/jdk1.6.0_11/bin/java -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/usr/local/tomcat6/conf/logging.properties -Djava.endorsed.dirs=/usr/local/tomcat6/endorsed -classpath :/usr/local/tomcat6/bin/bootstrap.jar -Dcatalina.base=/usr/local/tomcat6 -Dcatalina.home=/usr/local/tomcat6 -Djava.io.tmpdir=/usr/local/tomcat6/temp org.apache.catalina.startup.Bootstrap start
root     13187  0.0  0.2   5072   708 pts/0    R+   19:31   0:00 grep tomcat
启动成功！

4.访问测试
http://192.168.2.150:8080
会看到tomcat的主页

5.修改配置文件
# pwd
/usr/local/tomcat6/conf
# vim server.xml
<Connector port="8080" protocol="HTTP/1.1"   端口设置
<Host name="localhost"  appBase="webapps"    家目录，页面文件要放在webapps/ROOT下面
将家目录改成/www/web/
<Host name="localhost"  appBase="/www/web"
# mkdir -p /www/web/ROOT
# vim /www/web/ROOT/index.jsp
Hello,tomcat home!
重启tomcat,再次访问
改变访问
改变家目录的访问默认文件
# vim web.xml
<welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>

二.nginx安装配置

1.安装支持正则的pcre模块
# rpm -ivh  pcre-devel-6.6-2.el5_1.7.i386.rpm

2.安装nginx
# tar zxvf nginx-0.7.62.tar.gz
# cd nginx-0.7.62
# ./configure --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module
# make
# make install

3.启动nginx
# /usr/local/nginx/sbin/nginx

4.访问nginx(默认为80端口)
http://192.168.2.150

三.nginx与tomcat整合

1. 在/usr/local/nginx/conf下面添加文件proxy.conf
# cat /usr/local/nginx/confg/proxy.conf
proxy_redirect          off;
proxy_set_header        Host $host;
proxy_set_header        X-Real-IP $remote_addr; #获取真实IP
#proxy_set_header       X-Forwarded-For   $proxy_add_x_forwarded_for; #获取代理者的真实ip
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;

2.配置nginx.conf
# cat /usr/local/nginx/confg/nginx.conf
user  www www;
worker_processes  1;
pid     /usr/local/nginx/logs/nginx.pid;
events {
    use epoll;
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    include     /usr/local/nginx/conf/proxy.conf;  #一定要指向代理文件
    sendfile        on;
    tcp_nopush      on;
    keepalive_timeout  65;
    server {
        listen       80;
        server_name  localhost;
        charset gb2312;
        location / {
             root /www/web/ROOT;
             index  index.html index.htm;
        }
        location ~ .*.jsp$ {     #匹配以jsp结尾的，tomcat的网页文件是以jsp结尾        
                index   index.jsp;
                proxy_pass      http://127.0.0.1:8080; #主要在这里，设置一个代理
        }
        location /nginxstatus {
                stub_status on;
                access_log on;
                auth_basic "nginxstatus";
                auth_basic_user_file /usr/local/nagois/etc/htpasswd.users;
        }
        # redirect server error pages to the static page /50x.html
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
}

3.测试
在/www/web/ROOT下添加文件index.html
# cat index.html
the port:80
重启nginx
http://192.168.2.150
http://192.168.2.150:8080
http://192.168.2.150/index.jsp

在配置nginx提示如下错误时：
[emerg]: getpwnam(“www”) failed
解决方案：
在nginx.conf中 把user www www改为user nobody nobody既可
