linux下安装tomcat7.0

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

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/tomcat7mv 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,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/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

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。
