linux版本：CentOS 6.2

iso文件下载地址：[http://mirrors.163.com/centos/6.2/isos/i386/CentOS-6.2-i386-bin-DVD1.iso][http_mirrors.163.com_centos_6.2_isos_i386_CentOS-6.2-i386-bin-DVD1.iso]

**1. 安装JDK**

先用java命令查看系统是否安装了默认的openJDK，如果已安装，建议用yum remove java卸载之。

下载jdk：

wget –c http://download.oracle.com/otn-pub/java/jdk/7u5-b05/jdk-7u5-linux-i586.rpm

安装：rpm –ivh jdk-7u5-linux-i586.rpm

配置环境变量（等到tomcat安装好之后一起配置）

**2. 安装tomcat**

Tomca下载地址：

http://apache.etoak.com/tomcat/tomcat-7/v7.0.28/bin/apache-tomcat-7.0.28.tar.gz

下载后解压：tar -zxvf apache-tomcat-7.0.28

移动到/usr/local/tomcat7：mv apache-tomcat-7.0.28 /usr/local/tomcat7

设置目录可执行权限 chmod +x /usr/local/tomcat7  
  
**配置环境变量 **

编辑profile文件：vim /etc/profile

在文件中添加以下代码：  
   export JAVA\_HOME = /usr/java/jdk1.7.0\_05  
   export CALSSPATH = $JAVA\_HOME/lib/\*.\*     
   export PATH = $PATH:$JAVA\_HOME/bin       
   export TOMCAT\_HOME=/usr/local/tomcat7  
   export CATALINA\_HOME=/usr/local/tomcat7

保存文件退出编辑。

使设置立即生效：source /etc/profile

**至此，tomcat已经搭建完毕，下面所述的步骤主要是对tomcat的相关设置。**

启动tomcat： sh startup.sh 或者 sh /usr/local/tomcat7/bin/startup.sh

此时可在浏览器查看[http://localhost:8080][http_localhost_8080]，如果没有图形界面，则需要打开端口才可访问。

打开防火墙端口命令如下：

/sbin/iptables -I INPUT -p tcp --dport 8080 -j ACCEPT \#8080为端口

/etc/rc.d/init.d/iptables save \#保存

/etc/init.d/iptables restart \#重启防火墙使得立即生效

也可以在/etc/sysconfig/iptables文件中增加一行信息，

\-A RH-Firewall-1-INPUT -m state –state NEW -m tcp -p tcp –dport 8080 -j ACCEPT

查看防火墙状态的命令：/etc/init.d/iptables status

关闭防火墙的命令：/etc/init.d/iptables stop

修改tomcat端口为80                                                         
修改/usr/local/tomcat6/apache-tomcat-6.0.20/conf/中的server.xml文件将端口改为80                                                         
开启80端口  
在/etc/sysconfig/iptables中开放80端口  
\-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

开机启动  
在/etc/rc.d/init.d中添加tomcat的启动文件。

\#!/bin/bash  
\#  
\# tomcatd This shell script takes care of starting and stopping  
\# standalone tomcat  
\# chkconfig: 345 91 10  
\# description: tomcat service  
\# processname: tomcatd  
\# config file:

\# Source function library.  
. /etc/rc.d/init.d/functions

\# Source networking configuration.  
. /etc/sysconfig/network

\# Check that networking is up.  
\[ = "no" \] && exit 0

prog=tomcatd

export JAVA\_HOME=/usr/local/jdk/jdk1.7.0\_05  
export CATALINA\_HOME=/usr/local/tomcat7  
PATH=$PATH:$JAVA\_HOME/bin

STARTUP=$CATALINA\_HOME/bin/startup.sh  
SHUTDOWN=$CATALINA\_HOME/bin/shutdown.sh

if \[ ! -f $CATALINA\_HOME/bin/startup.sh \]  
then  
    echo "CATALINA\_HOME for tomcatd not available"  
    exit  
fi

start() \{  
    \# Start daemons.

echo -n $"Startting tomcat service: "  
    su - root -c $STARTUP  
    RETVAL=$?  
return $RETVAL  
\}

stop() \{  
    \# Stop daemons.  
    echo -n $"Stoping tomcat service: "  
    su - root -c $SHUTDOWN  
RETVAL=$?  
return $RETVAL  
\}

\# See how we were called.  
case "$1" in  
start)  
    start  
    ;;  
stop)  
    stop  
    ;;  
restart|reload)  
    stop  
    start  
    RETVAL=$?  
    ;;  
status)  
    status $prog  
    RETVAL=$?  
    ;;  
\*)  
    echo $"Usage: $0 \{start|stop|restart|status\}"  
    exit 1  
esac

exit $RETVAL

将tomcat的默认字符编码设置为UTF-8                             
在tomcat目录下conf文件夹下的server.xml中添加  
     
               connectionTimeout="20000"  
               redirectPort="8443"  
               URIEncoding="UTF-8" />  
在tomcat下的lib文件夹中加入mysql的连接包

修改catalina.sh  
有时WEB系统比较大要添加tomcat的内存  
if \[ -z "$LOGGING\_MANAGER" \]; then  
JAVA\_OPTS="$JAVA\_OPTS -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"  
else  
JAVA\_OPTS="$JAVA\_OPTS $LOGGING\_MANAGER"  
fi

\# ----- Execute The Requested Command -----------------------------------------  
JAVA\_OPTS="$JAVA\_OPTS -Xms512m -Xmx512m -XX:MaxNewSize=512m -XX:MaxPermSize=512m"

Tomcat管理用户密码设置，

修改文件 tomcat/conf/tomcat-users.xml

保存后重启，即可登录tomcat管理页面。
