nginx+配置java环境变量配置_Nginx+Tomcat安装配置

Tomcat是一个轻量级应用服务器,在中小型系统和并发访问用户不是很多的场合下被普遍使用,是开发和调试JSP程序的首选。可以这样认为,当在一台机器上配置好Tomcat服务器,可利用它响应对HTML 页面的访问请求。实际上Tomcat 部分是Nginx服务器的扩展,但它是独立运行的,所以当你运行tomcat时,它实际上作为一个与Nginx 独立的进程单独运行的。

安装tomcat

Tomcat的安装分为两个步骤:安装JDK和安装Tomcat.

JDK(Java Development Kit)是Sun Microsystems针对Java开发员的产品。自从Java推出以来,JDK已经成为使用最广泛的Java SDK. JDK是整个Java的核心,包括了Java运行环境,Java工具和Java基础的类库。所以要想运行jsp的程序必须要有JDK的支持,理所当然安装 Tomcat的前提是安装好JDK.

安装JDK

下载JDK

cd /usr/local/src/

下载JDK官网:

http://www.Oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

安装:rpm -ivh jdk-7-linux-i586.rpm

设置环境变量

vim /etc/profile

向文件里面追加以下内容:

JAVA_HOME=/usr/java/jdk1.7.0_45

JRE_HOME=/usr/java/jdk1.7.0_45/jre

PATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/bin

CLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib

export JAVA_HOME JRE_HOME PATH CLASSPATH

使修改生效

[root@localhost ~]# source /etc/profile  //使修改立即生效

[root@localhost ~]# echo $PATH  //查看PATH值

检测是否设置正确:

java -version

安装Tomcat

cd /usr/local/src/

wget http://www.aminglinux.com/bbs/data/attachment/forum/apache-tomcat-7.0.14.tar.gz

如果觉得这个版本不适合,可以到官方网站(http://tomcat.apache.org/)下载。

tar zxvf apache-tomcat-7.0.14.tar.gz

mv apache-tomcat-7.0.14 /usr/local/tomcat

cp -p /usr/local/tomcat/bin/catalina.sh /etc/init.d/tomcat

vim /etc/init.d/tomcat

在第二行加入以下内容:

# chkconfig: 112 63 37

# description: tomcat server init script

# Source Function Library

. /etc/init.d/functions

JAVA_HOME=/usr/local/jdk1.6.0_23/

CATALINA_HOME=/usr/local/tomcat

保存文件后,执行以下操作:

chmod 755 /etc/init.d/tomcat

chkconfig --add tomcat

chkconfig tomcat on

启动tomcat:

service tomcat start

查看是否启动成功:

ps aux |grep tomcat

如果有进程的话,请在浏览器中输入http://IP:8080/ 你会看到tomcat的主界面。

配置tomcat

1. 配置tomcat服务的访问端口

tomcat默认启动的是8080,如果你想修改为80,则需要修改server.xml文件:

vim /usr/local/tomcat/conf/server.xml

找到:

修改为:

2. 配置新的虚拟主机

cd /usr/local/tomcat/conf/

vim server.xml

找到下一行插入新的内容如下:

unpackWARs="false" autoDeploy="true"

xmlValidation="false" xmlNamespaceAware="false">

保存后,重启tomcat:

service tomcat stop

service tomcat start

测试tomcat

先创建tomcat的测试文件:

vim /data/tomcatweb/111.jsp

加入如下内容:

Now time is:

保存后,使用curl测试:

[root@localhost ~]# curl -xlocalhost:80 www.123.cn/111.jsp

看看运行结果是否是:

Now time is: Thu Jun 13 15:26:03 CST 2013

tomcat连接MySQL数据库:

cat jdbc.properties

jdbc.driverClassName=com.mysql.jdbc.Driver

jdbc.url=jdbc:mysql://localhost:3306/cphd?useUnicode=true&characterEncoding=utf-8

jdbc.username=WordPress

jdbc.password=WordPress

hibernate.dialect=org.hibernate.dialect.MySQLDialect

hibernate.show_sql=false

hibernate.format_sql=true

hibernate.cache.provider_class=org.hibernate.cache.EhCacheProvider

hibernate.cache.use_query_cache=true

hibernate.schemaUpdate=false

Nginx配置所有jsp的页面均交由tomcat处理:

server {

listen 80;

server_name baidu.com www.baidu.com;

index index.html index.jsp;

root /home/www/cphd/cphd;

rewrite ^/(.*)$ https://www.baidu.com/$1 permanent;

location ~ /\. { access_log off; log_not_found off; deny all; }

location ~* (\.jsp)|(\.do)$ {

proxy_pass http://127.0.0.1:8080;

}

location /cphd {

root /home/www/cphd;

include proxy.conf;

proxy_pass http://127.0.0.1:8080;

}

}

Tomcat配置:

vi /usr/local/tomcat/conf/server.xml +71

enableLookups="false" acceptCount="1000"

useBodyEncodingForURI="true"
