CentOS下配置安装Tomcat并配置JDK环境

第一步、下载JDKTomcat

下载JDK

https://edelivery.oracle.com/otn-pub/java/jdk/7u45-b18/jdk-7u45-linux-x64.rpm

或者:#wget https://edelivery.oracle.com/otn-pub/java/jdk/7u45-b18/jdk-7u45-linux-x64.rpm

版本:jdk-7u45-linux-x64.rpm

安装JDK

[root@thinkpig007 ss]# rpm �Civhjdk-7u45-linux-x64.rpm

下载tomcat7

http://apache.fayea.com/apache-mirror/tomcat/tomcat-7/v7.0.47/bin/apache-tomcat-7.0.47.tar.gz

或者:

#wget http://apache.fayea.com/apache-mirror/tomcat/tomcat-7/v7.0.47/bin/apache-tomcat-7.0.47.tar.gz

版本:apache-tomcat-7.0.47.tar.gz

第二步、卸载系统老的tomcat

卸载使用yum自动安装的tomcat6

#yum remove tomcat6

查看本机的jdk本版

#java �Cversion

[root@thinkpig007 ss]# java-version

java version"1.6.0_24"

OpenJDK Runtime Environment(IcedTea6 1.11.13) (rhel-1.65.1.11.13.el6_4-x86_64)

OpenJDK 64-Bit Server VM(build 20.0-b12, mixed mode)

[root@thinkpig007 ss]#

查看本机已经安装的JDK版本

[root@thinkpig007 ss]# cd/usr/java/

default/     jdk1.7.0_45/ latest/      

注意:这里的jdk目录就是我们修改/etc/profile环境变量是所要填写路径及目录名称,如下

exportJAVA_HOME=/usr/java/jdk1.7.0_45

(详解:“第三步、安装tomcat7”中的“(4) 添加tomcat环境变量”)

[root@thinkpig007 ss]# cd/usr/java/

[root@thinkpig007jdk1.7.0_45]# cat release

JAVA_VERSION="1.7.0"

OS_NAME="Linux"

OS_VERSION="2.6"

OS_ARCH="amd64"

SOURCE=" .:f0cdb08a4624corba:80f65a8f5850 deploy:2b1995e2c8f5 hotspot:12374864c655hotspot/make/closed:2c0b7ecdd92d hotspot/src/closed:b8a50da977b6hotspot/test/closed:47eee40b7622 install:99193876e329 jaxp:4beb90ab48f7jaxws:65b0f3ccdc8b jdk:c5ca4daec23b jdk/make/closed:917a8e455dc3jdk/src/closed:b6127fd9ff72 jdk/test/closed:e3c74041acc5 langtools:ba3ff27d4082pubs:476da1da84f7 sponsors:c732b1a6f43b"

BUILD_TYPE=commercial

第三步、安装tomcat7

安装tomcat

(1)解压apache-tomcat-7.0.47.tar.gz

[root@thinkpig007 ss]# tar-zxvf apache-tomcat-7.0.47.tar.gz

(2)复制解压后的目录apache-tomcat-7.0.47/usr/local下并重命名为tomcat7

[root@thinkpig007 ss]# cp -Rapache-tomcat-7.0.47 /usr/local/tomcat7

注意:/usr/local/tomcat7就是后面我们要修改环境变量时需要填写的目录路径

(3)进入bin目录

[root@thinkpig007 ss]# cd/usr/local/tomcat7/

[root@thinkpig007 tomcat7]# cdbin/

[root@thinkpig007 bin]#

没修改环境变量前,启动tomcat出错

[root@thinkpig007 bin]#./startup.sh

Cannot find ”/usr/local/tomcat”/bin/setclasspath.sh

(4)添加tomcat环境变量

# [root@thinkpig007 ~]# vi/etc/profile

加入下代码

#set environment variable

exportJAVA_HOME=/usr/java/jdk1.7.0_45

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

exportTOMCAT_HOME=/usr/local/tomcat7

exportCATALINA_HOME=/usr/local/tomcat7

exportPATH=$PATH:$JAVA_HOME/bin

(5)修改应用环境变量,是配置生效

[root@thinkpig007 bin]# source/etc/profile

(6)修改环境变量后重新启动tomcat启动成功

This file is needed to runthis program

[root@thinkpig007 bin]# ./startup.sh

Using CATALINA_BASE:   /usr/local/tomcat7

Using CATALINA_HOME:   /usr/local/tomcat7

Using CATALINA_TMPDIR:/usr/local/tomcat7/temp

Using JRE_HOME:        /usr/java/jdk1.7.0_45

Using CLASSPATH:      /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar


(7)关闭tomcat

[root@thinkpig007 bin]#./shutdown.sh

Using CATALINA_BASE:   /usr/local/tomcat7

Using CATALINA_HOME:   /usr/local/tomcat7

Using CATALINA_TMPDIR:/usr/local/tomcat7/temp

Using JRE_HOME:        /usr/java/jdk1.7.0_45

Using CLASSPATH:      /usr/local/tomcat7/bin/bootstrap.jar:/usr/local/tomcat7/bin/tomcat-juli.jar

[root@thinkpig007 bin]#

第四步、添加管理权限

默认情况下,Tomcat并没提供具有管理权限的账号,所以需要添加具有这种权限的账号。角色manager-gui具有这种权限,但在系统用户控制文件tomcat-users.xml中并没有设置这两种角色和对应的用户,所以需要添加这种角色和用户,方法是打开tomcat-users.xml文件,添加如下内容:

<rolerolename="manager-gui"/>

<userusername="manager" password="manager"roles="manager-gui"/>

然后重启 Tomcat 服务器,文件修改生效。
