安装配置jdk和tomcat

请1我的

1,首先，暂停iptables服务

[iyunv@localhost ~]# service iptables stop
[iyunv@localhost ~]# chkconfig iptables off

2,jdk的安装和配置：

  （1），安装jdk命令: rpm -ivh jdk-8u51-linux-x64.rpm

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

[iyunv@localhost install]# ll total 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 [iyunv@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：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45

[iyunv@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 file if [ $UID -gt 199 ] && [ "`id -gn`" = "`id -un`" ]; then     umask 002 else     umask 022 fi for i in /etc/profile.d/*.sh ; do     if [ -r "$i" ]; then         if [ "${-#*i}" != "$-" ]; then             . "$i"         else             . "$i" >/dev/null 2>&1         fi     fi done unset i unset -f pathmunge export JAVA_HOME=/usr/java/jdk1.8.0_51 export PATH=$JAVA_HOME/bin:$PATH export CLASSPATH=$JAVA_HOME/lib:.:$CLASSPATH

（3)测试：

查看java版本号：java -version

1 2 3 4

[iyunv@localhost install]# java -version java 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

1 2	[iyunv@localhost install]# javac -version javac 1.8.0_51

3,tomcat安装配置
  （1）,创建组和用户tomcat

1 2 3 4 5 6 7 8 9 10

[iyunv@localhost install]# groupadd tomcat [iyunv@localhost install]# useradd -g tomcat tomcat [iyunv@localhost install]# passwd tomcat Changing password for user tomcat. New password: BAD PASSWORD: it is too simplistic/systematic BAD PASSWORD: is too simple Retype new password: passwd: all authentication tokens updated successfully. [iyunv@localhost install]#

  （2）切换用户并创建tomcat用户的目录：

1 2 3

[iyunv@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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62

[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.html apache-tomcat-7.0.63/webapps/examples/servlets/chat/index.jsp apache-tomcat-7.0.63/webapps/examples/servlets/chat/index.jsp.html apache-tomcat-7.0.63/webapps/examples/servlets/chat/login.jsp apache-tomcat-7.0.63/webapps/examples/servlets/chat/login.jsp.html apache-tomcat-7.0.63/webapps/examples/servlets/chat/post.jsp apache-tomcat-7.0.63/webapps/examples/servlets/chat/post.jsp.html apache-tomcat-7.0.63/webapps/examples/servlets/cookies.html apache-tomcat-7.0.63/webapps/examples/servlets/helloworld.html apache-tomcat-7.0.63/webapps/examples/servlets/images/code.gif apache-tomcat-7.0.63/webapps/examples/servlets/images/execute.gif apache-tomcat-7.0.63/webapps/examples/servlets/images/return.gif apache-tomcat-7.0.63/webapps/examples/servlets/index.html apache-tomcat-7.0.63/webapps/examples/servlets/reqheaders.html apache-tomcat-7.0.63/webapps/examples/servlets/reqinfo.html apache-tomcat-7.0.63/webapps/examples/servlets/reqparams.html apache-tomcat-7.0.63/webapps/examples/servlets/sessions.html apache-tomcat-7.0.63/webapps/examples/websocket-deprecated/chat.html apache-tomcat-7.0.63/webapps/examples/websocket-deprecated/echo.html apache-tomcat-7.0.63/webapps/examples/websocket-deprecated/index.html apache-tomcat-7.0.63/webapps/examples/websocket-deprecated/snake.html apache-tomcat-7.0.63/webapps/examples/websocket/chat.xhtml apache-tomcat-7.0.63/webapps/examples/websocket/drawboard.xhtml apache-tomcat-7.0.63/webapps/examples/websocket/echo.xhtml apache-tomcat-7.0.63/webapps/examples/websocket/index.xhtml apache-tomcat-7.0.63/webapps/examples/websocket/snake.xhtml apache-tomcat-7.0.63/webapps/host-manager/META-INF/context.xml apache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/401.jsp apache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/403.jsp apache-tomcat-7.0.63/webapps/host-manager/WEB-INF/jsp/404.jsp apache-tomcat-7.0.63/webapps/host-manager/WEB-INF/web.xml apache-tomcat-7.0.63/webapps/host-manager/images/add.gif apache-tomcat-7.0.63/webapps/host-manager/images/asf-logo.gif apache-tomcat-7.0.63/webapps/host-manager/images/code.gif apache-tomcat-7.0.63/webapps/host-manager/images/design.gif apache-tomcat-7.0.63/webapps/host-manager/images/docs.gif apache-tomcat-7.0.63/webapps/host-manager/images/fix.gif apache-tomcat-7.0.63/webapps/host-manager/images/tomcat.gif apache-tomcat-7.0.63/webapps/host-manager/images/update.gif apache-tomcat-7.0.63/webapps/host-manager/images/void.gif apache-tomcat-7.0.63/webapps/host-manager/index.jsp apache-tomcat-7.0.63/webapps/host-manager/manager.xml apache-tomcat-7.0.63/webapps/manager/META-INF/context.xml apache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/401.jsp apache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/403.jsp apache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/404.jsp apache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/sessionDetail.jsp apache-tomcat-7.0.63/webapps/manager/WEB-INF/jsp/sessionsList.jsp apache-tomcat-7.0.63/webapps/manager/WEB-INF/web.xml apache-tomcat-7.0.63/webapps/manager/images/add.gif apache-tomcat-7.0.63/webapps/manager/images/asf-logo.gif apache-tomcat-7.0.63/webapps/manager/images/code.gif apache-tomcat-7.0.63/webapps/manager/images/design.gif apache-tomcat-7.0.63/webapps/manager/images/docs.gif apache-tomcat-7.0.63/webapps/manager/images/fix.gif apache-tomcat-7.0.63/webapps/manager/images/tomcat.gif apache-tomcat-7.0.63/webapps/manager/images/update.gif apache-tomcat-7.0.63/webapps/manager/images/void.gif apache-tomcat-7.0.63/webapps/manager/index.jsp apache-tomcat-7.0.63/webapps/manager/status.xsd apache-tomcat-7.0.63/webapps/manager/xform.xsl

  (4)切换目录并配置文件：

1 2 3

[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
