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

下面的可能更全面一些

CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/jre/lib:$JAVA_HOME/jre/bin

 

export CLASSPATH

PATH=$JAVA_HOME/bin:$PATH
export PATH

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

 

二、设置jdk环境变量

1

2

3

4

5

vi /etc/profile

 

export JAVA_HOME=/usr/java/jdk1.6.0_45

export CLASSPATH=$JAVA_HOME/jre/lib:$JAVA_HOME/lib

export PATH=$PATH:$JAVA_HOME/bin

然后保存退出,使环境变量生效

source /etc/profile

java -version 

 

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

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"

修改访问项目路径

1<Host name="localhost"  appBase="/root/webfile/webapps" unpackWARs="true" autoDeploy="true">

2<!-- 设置默认项目名称 -->

<Context path="" docBase="/root/webfile/web" reloadable="true"/

  • path代表用浏览器访问的时候的的路径，如来访问path=”/web”

  • docBase为你的项目的路径，这里同样既可以用相对路径，也可以用绝对路径。设置好了之后就会把项目自动映射到ROOT

  • reloadable，如果这个属性设为true，tomcat服务器在运行状态下会监视在WEB-INF/classes和WEB-INF/lib目录下class文件的改动，如果监测到有class文件被更新的，服务器会自动重新加载Web应用

# 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

yum –y install pcre*

yum -y install zlib*

yum -y install openssl*

 

 

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)

 

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      ; #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

/usr/local/nginx/sbin/nginx -s reload

检测配置

/usr/local/nginx/sbin/nginx -t
