linux下安装配置tomcat

Linux下Tomcat安装配置以及Windows不能连接服务器Tomcat解决方案

一、从官方网站上下载tomcat软件包。

官网地址： http://tomcat.apache.org/
点击左侧的 download的一个版本，我选择的是 tomcat7.0，选择一个后缀名为.tar.gz文件直接下载到本地。

二、通过工具SSH Secure 上传至linux服务器中，进行解压

解压tomcat压缩文件： 

 #tar zxvf apache-tomcat-7.0.53.tar.gz

将解压后的tomcat文件移动至/usr/local下

 #mv apach-tomcat-6.0.16 /usr/local

三、配置tomcat环境；【之前我已经安装好JDK了】

 编辑profie文件：

#vi /etc/profile

将下面文件copy到export PATH USER LOGNAME MAIL HOSTNAME HISTSIZE HISTCONTROL后面；具体jdk路径根据你安装的位置来配置；

export JAVA_HOME=/usr/java/jdk1.7.0_15
export CLASSPATH=.:$JAVA_HOME/jre/lib/rt.jar:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$PATH:$JAVA_HOME/bin
export CATALINA_HOME=/usr/local/apache-tomcat-7.0.53
export CATALINA_BASE=/usr/local/apache-tomcat-7.0.53

保存退出，重新登录使之生效。 
   
四、启动tomcat服务器
进入到/usr/local/apach-tomcat-6.0.20/bin目录

运行./startup.sh

启动成功会出现如下内容：
Using CATALINA_BASE:   /usr/local/apache-tomcat-7.0.53
Using CATALINA_HOME:   /usr/local/apache-tomcat-7.0.53
Using CATALINA_TMPDIR: /usr/local/apache-tomcat-7.0.53/temp
Using JRE_HOME:        /usr/java/jdk1.7.0_15

Using CLASSPATH:       /usr/local/apache-tomcat-7.0.53/bin/bootstrap.jar:/usr/local/apache-tomcat-7.0.53/bin/tomcat-juli.jar
Tomcat started.

五、测试是否启动成功

在linux浏览器中输入http://localhost:8080/就可以看到tomcat的log了

如果8080端口被占用，或者你只是想修改tomcat的端口，请参考如下文件，我直接copy上来了。【我这里是修改为9080端口】

修改完后，启动tomcat，如果 Windows访问 Linux的Tomcat，显示 无法连接，先查看tomcat下的logs日志文件，如果现实地址已被占用，则需重新修改，如果已经正常启动，说明防火墙未关闭。则只有修改linux防火墙的配置，打开8080端口。

1，在开启了防火墙时，做如下设置，开启相关端口，修改/etc/sysconfig/iptables 文件，添加以下内容：
        -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT

2、直接关闭Linux防火墙。

在此说一下关于启动和关闭防火墙的命令

1) 重启后生效
       开启： chkconfig iptables on
       关闭： chkconfig iptables off
   2) 即时生效，重启后失效
       开启： service iptables start
       关闭： service iptables stop
