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。

下载jdk:oracle的jdk

安装:rpm –ivh jdk-7u79-linux-x64.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://mirrors.cnnic.cn/apache/tomcat/tomcat-7/v7.0.63/bin/apache-tomcat-7.0.63.tar.gz

下载后解压:tar -zxvf apache-tomcat-7.0.63.tar.gz

移动到/usr/local/tomcatmv apache-tomcat-7.0.63 /usr/local/tomcat

设置目录可执行权限 chmod +x /usr/local/tomcat

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_79

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

export PATH=$JAVA_HOME/bin:$PATH

export TOMCAT_HOME=/usr/local/tomcat

export CATALINA_HOME=/usr/local/tomcat

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,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
/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

/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/tomcat
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

tomcat的默认字符编码设置为UTF-8                           

tomcat目录下conf文件夹下的server.xml中添加
   
               connectionTimeout="20000"
               redirectPort="8443"
               URIEncoding="UTF-8" />

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。
