export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/lib:$CLASSPATH
保存并退出，重啟機器，輸入
# echo $PATH
查看是否識別jdk路徑
# java -version
顯示jdk當前版本

安裝Tomcat7
# cd /home/java
# wget http://mirrors.tuna.tsinghua.edu.cn/apache/tomcat/tomcat-7/v7.0.78/bin/apache-tomcat-7.0.78.tar.gz
# tar -zxvf apache-tomcat-7.0.78.tar.gz
# mv apache-tomcat-7.0.78 tomcat7
# /home/java/tomcat7/bin/startup.sh
啟動tomcat即可，然后網頁打開 0.0.0.0:8080 查看效果

與Nginx實現動靜分離
Nginx安裝方法：http://blog.csdn.net/kenkao/article/details/53333595
Nginx添加Tomcat代理：
#
vim /etc/nginx/nginx.conf
添加如下內容：include enable-jsp.conf;
# vim /etc/nginx/enable-jsp.conf
輸入如下內容：
location ~ (\.jsp)|(\.do)$ ###jsp、do的動態請求都交給后面的tomcat處理
{
proxy_pass http://127.0.0.1:8080;
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;
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;
}
重定向Tomcat的ROOT目錄到Nginx默認html目錄：(
因為靜態文件全部導向Nginx跟目錄，動靜結合模式下訪問jsp，其相對路徑下的靜態文件會失效)# vim /home/java/tomcat7/conf/server.xml
<Context path="" docBase="/usr/share/nginx/html/" debug="0"/>
重啟Tomcat：
# cd /home/java/tomcat7/bin
# ./shutdown.sh
Tomcat ROOT 完整目錄拷貝到 /usr/share/nginx/html
# cp -a /home/java/tomcat7/webapps/ROOT/* /usr/share/nginx/html
訪問Nginx主頁：127.0.0.1/index.html
訪問Tomcat主頁：127.0.0.1/index.jsp
阿里云、騰訊云 在配置完畢tomcat之后，第一次訪問會奇慢無比，之后就沒問題了...
