1,首先，暂停iptables服务
[root@localhost ~]# service iptables stop
[root@localhost ~]# chkconfig iptables off
2,jdk卸载
（1）查找jdk安装信息
[root@iZ23s6vhhjjZ apache-tomcat-7.0.63]# rpm -qa|grep gcjlibgcj-4.4.7-4.el6.x86_64
java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
[root@iZ23s6vhhjjZ apache-tomcat-7.0.63]#rpm -e java-1.5.0-gcj-1.5.0.0-29.1.el6.x86_64
[root@iZ23s6vhhjjZ apache-tomcat-7.0.63]#rpm -e libgcj-4.4.7-4.el6.x86_64
（2）卸载
[root@iZ23s6vhhjjZ apache-tomcat-7.0.63]# rpm -qa|grep jdkjdk-1.7.0_79-fcs.x86_64[root@iZ23s6vhhjjZ apache-tomcat-7.0.63]#rpm -e --nodeps jdk-1.7.0_79-fcs.x86_64
3,jdk的安装和配置：
（1），安装jdk命令: rpm -ivh jdk-8u51-linux-x64.rpm
[root@localhost install]# lltotal 481168-rw-r--r--. 1 root root 8850470 Nov 2 22:43 apache-tomcat-7.0.63.tar.gz-rw-r--r--. 1 root root 137808216 Jan 13 15:09 jdk-8u51-linux-x64.rpm-rw-r--r--. 1 root root 33203321 Nov 20 11:31 mysql-5.6.25.tar.gz-rw-r--r--. 1 root root 312845162 Nov 13 15:19 mysql-5.6.27-linux-glibc2.5-x86_64.tar.gz[root@localhost install]# rpm -ivh jdk-8u51-linux-x64.rpm Preparing... ########################################### [100%] 1:jdk1.8.0_51 ########################################### [100%]Unpacking JAR files... rt.jar... jsse.jar... charsets.jar... tools.jar... localedata.jar... jfxrt.jar... plugin.jar... javaws.jar... deploy.jar...
（2)配置环境变量：
[root@localhost install]# vi /etc/profile# /etc/profile# System wide environment and startup programs, for login setup# Functions and aliases go in /etc/bashrc# It's NOT a good idea to change this file unless you know what you# are doing. It's much better to create a custom.sh shell script in# /etc/profile.d/ to make custom changes to your environment, as this# will prevent the need for merging in future updates.pathmunge () { case ":${PATH}:" in *:"$1":*) ;; *) if [ "$2" = "after" ] ; then PATH=$PATH:$1 else PATH=$1:$PATH fi esac}"/etc/profile" 78L, 1796C# By default, we want umask to get set. This sets it for login shell# Current threshold for system reserved uid/gids is 200# You could check uidgid reservation validity in# /usr/share/doc/setup-*/uidgid fileif [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then umask 002else umask 022fifor i in /etc/profile.d/*.sh ; do if [ -r "$i" ]; then if [ "${-#*i}" != "$-" ]; then . "$i" else . "$i" >/dev/null 2>&1 fi fidoneunset iunset -f pathmungeexport JAVA_HOME=/usr/java/jdk1.8.0_51export PATH=$JAVA_HOME/bin:$PATHexport CLASSPATH=$JAVA_HOME/lib:.:$CLASSPATH
(3) 配置的环境变量生效：source /etc/profile
[root@localhost install]# source /etc/profile
（4)测试：
查看java版本号：java -version
[root@localhost install]# java -versionjava version "1.8.0_51"Java(TM) SE Runtime Environment (build 1.8.0_51-b16)Java HotSpot(TM) 64-Bit Server VM (build 25.51-b03, mixed mode)
查看javac版本号命令：javac -version
[root@localhost install]# javac -versionjavac 1.8.0_51
4,tomcat安装配置
（1）,创建组和用户tomcat
[root@localhost install]# groupadd tomcat[root@localhost install]# useradd -g tomcat tomcat[root@localhost install]# passwd tomcatChanging password for user tomcat.New password: BAD PASSWORD: it is too simplistic/systematicBAD PASSWORD: is too simpleRetype new password: passwd: all authentication tokens updated successfully.[root@localhost install]#
（2）切换用户并创建tomcat用户的目录：
[root@localhost install]# su tomcat[tomcat@localhost install]$ mkdir /home/tomcat/server [tomcat@localhost install]$
（3）解压tomcat压缩包并放到指定的目录里
[tomcat@localhost install]$ tar zxvf apache-tomcat-7.0.63.tar.gz -C /home/tomcat/server/apache-tomcat-7.0.63/webapps/examples/jsp/xml/xml.jsp.htmlapache-tomcat-7.0.63/webapps/examples/servlets/chat/index.jspapache-tomcat-7.0.63/webapps/examples/servlets/chat/index.jsp.htmlapache-tomcat-7.0.63/webapps/examples/servlets/chat/login.jspapache-tomcat-7.0.63/webapps/examples/servlets/chat/login.jsp.htmlapache-tomcat-7.0.63/webapps/examples/servlets/chat/post.jspapache-tomcat-7.0.63/webapps/examples/servlets/chat/post.jsp.htmlapache-tomcat-7.0.63/webapps/examples/servlets/cookies.htmlapache-tomcat-7.0.63/webapps/examples/servlets/helloworld.htmlapache-tomcat-7.0.63/webapps/examples/servlets/images/code.gifapache-tomcat-7.0.63/webapps/examples/servlets/images/execute.gifapache-tomcat-7.0.63/webapps/examples/servlets/images/return.gifapache-tomcat-7.0.63/webapps/examples/servlets/index.htmlapache-tomcat-7.0.63/webapps/examples/servlets/reqheaders.htmlapache-tomcat-7.0.63/webapps/examples/servlets/reqinfo.htmlapache-tomcat-7.0.63/webapps/examples/servlets/reqparams.htmlapache-tomcat-7.0.63/webapps/examples/servlets/sessions.htmlapache-tomcat-7.0.63/webapps/examples/websocket-deprecated/chat.htmlapache-tomcat-7.0.63/webapps/examples/websocket-deprecated/echo.htmlapache-tomcat-7.0.63/webapps/examples/websocket-deprecated/index.htmlapache-tomcat-7.0.63/webapps/examples/websocket-deprecated/snake.htmlapache-tomcat-7.0.63/webapps/examples/websocket/chat.xhtmlapache-tomcat-7.0.63/webapps/examples/websocket/drawboard.xhtmlapache-tomcat-7.0.63/webapps/examples/websocket/echo.xhtmlapache-tomcat-7.0.63/webapps/examples/websocket/index.xhtmlapache-tomcat-7.0.63/webapps/examples/websocket/snake.xhtmlapache-tomcat-7.0.63/webapps/host-manager/META-INF/context.xmlapache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/401.jspapache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/403.jspapache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/404.jspapache-tomcat-7.0.63/webapps/host-manager/WEB-INF/web.xmlapache-tomcat-7.0.63/webapps/host-manager/images/add.gifapache-tomcat-7.0.63/webapps/host-manager/images/asf-logo.gifapache-tomcat-7.0.63/webapps/host-manager/images/code.gifapache-tomcat-7.0.63/webapps/host-manager/images/design.gifapache-tomcat-7.0.63/webapps/host-manager/images/docs.gifapache-tomcat-7.0.63/webapps/host-manager/images/fix.gifapache-tomcat-7.0.63/webapps/host-manager/images/tomcat.gifapache-tomcat-7.0.63/webapps/host-manager/images/update.gifapache-tomcat-7.0.63/webapps/host-manager/images/void.gifapache-tomcat-7.0.63/webapps/host-manager/index.jspapache-tomcat-7.0.63/webapps/host-manager/manager.xmlapache-tomcat-7.0.63/webapps/manager/META-INF/context.xmlapache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/401.jspapache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/403.jspapache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/404.jspapache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/sessionDetail.jspapache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/sessionsList.jspapache-tomcat-7.0.63/webapps/manager/WEB-INF/web.xmlapache-tomcat-7.0.63/webapps/manager/images/add.gifapache-tomcat-7.0.63/webapps/manager/images/asf-logo.gifapache-tomcat-7.0.63/webapps/manager/images/code.gifapache-tomcat-7.0.63/webapps/manager/images/design.gifapache-tomcat-7.0.63/webapps/manager/images/docs.gifapache-tomcat-7.0.63/webapps/manager/images/fix.gifapache-tomcat-7.0.63/webapps/manager/images/tomcat.gifapache-tomcat-7.0.63/webapps/manager/images/update.gifapache-tomcat-7.0.63/webapps/manager/images/void.gifapache-tomcat-7.0.63/webapps/manager/index.jspapache-tomcat-7.0.63/webapps/manager/status.xsdapache-tomcat-7.0.63/webapps/manager/xform.xsl
(4)切换目录并配置文件：
[tomcat@localhost install]$ cd /home/tomcat/server/apache-tomcat-7.0.63/conf/[tomcat@localhost conf]$ cp server.xml server.xml.bak[tomcat@localhost conf]$ vi server.xml
(5）启动关闭测试
