wdcp添加tomcat，同时支持php和java教程
本文主要讲如何在LNAMP环境下安装JDK+Tomcat6使同一台服务器同时支持PHP和JAVA语言。服务器系统和各软件版本如下所示：

选择jdk1.6安装
# yum -y install java-1.6.0-openjdk*
其它版本请自己修改对应的版本号安装
检测是否安装成功
# java -version
java version "1.6.0_33"
OpenJDK Runtime Environment (IcedTea6 1.13.5) (rhel-1.13.5.0.el6_6-x86_64)
OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)
安装tomcat6
因为wdcp后台默认安装的端口是8080,tomcat默认端口也是8080为了避免冲突请提前把wdcp后台端口改为其它端口(如:8089...)
可以到wdcp后台系统设置中手动修改，如下图：
# yum install tomcat6 tomcat6-webapps tomcat6-admin-webapps
安装成功 启动
# service tomcat6 start
其它命令：service tomcat6 {start|stop|restart|condrestart|try-restart|reload|force-reload|status|version}
启动成功，访问测试：http://ip:8080
如下图所示即为安装成功：
配置nginx和tomcat，使其不加端口号，直接通过域名也能访问
首先增加解析，使域名指向到主机IP,本地可以直接改host实现
解析正常
不加8080端口访问
添加8080端口访问
接下来修改nginx和tomcat的配置使其不加端口号也能访问到tomcat的webservice
# cd /www/wdlinux/nginx/conf/vhost/
# vi myweb.com.conf
添加如下内容
server {
listen 80;
server_name www.myweb.com myweb.com;
#root /www/web/master_myweb_com/public_html;
index index.html index.jsp index.htm;
error_page 400 /errpage/400.html;
error_page 403 /errpage/403.html;
error_page 404 /errpage/404.html;
error_page 405 /errpage/405.html;
location ~ \.jsp$ {
proxy_pass http://127.0.0.1:8080;
include naproxy.conf;
}
location / {
try_files $uri @tomcat;
}
location @tomcat {
proxy_pass http://127.0.0.1:8080;
include naproxy.conf;
}
access_log /www/web_logs/myweb_com_access.log wwwlogs;
error_log /www/web_logs/myweb_com_error.log;
}
重新加载nginx配置文件或重启nginx
# service nginxd reload
nginx: the configuration file /www/wdlinux/nginx/conf/nginx.conf syntax is ok
nginx: configuration file /www/wdlinux/nginx/conf/nginx.conf test is successful
不加端口号访问测试：
至此nginx已经成功将来自myweb.com域名的请求代理到8080端口
如果需要配置多域名的话，还需要修改tomcat虚拟主机配置文件
默认配置文件路径：/etc/tomcat6/
默认项目路径：/var/lib/tomcat6/webapps/
tomcat默认指向/var/lib/tomcat6/webapps/ROOT目录
创建新项目目录，这里直接复制ROOT项目，进行修改
# pwd
/var/lib/tomcat6/webapps
# chown -R root myweb.com
修改权限，使新项目权限和默认项目权限一致
# chgrp -R tomcat myweb.com
# ll
总用量 24
drwxrwxr-x 5 root tomcat 4096 10月 30 22:06 examples
drwxrwxr-x 5 root tomcat 4096 10月 30 22:06 host-manager
drwxrwxr-x 5 root tomcat 4096 10月 30 22:06 manager
drwxr-xr-x 3 root tomcat 4096 10月 30 22:48 myweb.com
drwxrwxr-x 3 root tomcat 4096 10月 30 22:06 ROOT
drwxrwxr-x 5 root tomcat 4096 10月 30 22:06 sample
# cd myweb.com/
# rm -f index.html
# vi index.jsp
写入：WebService is Tomcat
不要忘记删除ROOT项目或者对它重命，否则新项目不生效
# mv ROOT/ ROOT.BAK
修改tomcat虚拟主机配置
# vi /etc/tomcat6/server.xml
在最下面<Host></Host>标签后面添加如下内容
<!--myweb.com host config-->
<Host name="www.myweb.com" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
<Context path="/" reloadable="true" docBase="myweb.com"/>
<Alias>myweb.com</Alias>
<!-- SingleSignOn valve, share authentication between web applications
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
-->
<!-- Access log processes all example.
Documentation at: /docs/config/valve.html -->
<!--
<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
prefix="localhost_access_log." suffix=".txt" pattern="common" resolveHosts="false"/>
-->
</Host>
如下图所示
重启tomcat，测试http://xxx.com
# service tomcat6 restart
