Centos 6.5 安装JDK 和 tomcat

介绍

今天要发布一个java web 项目，然后发现机器上没有装jdk和tomcat，所以搜索帖子简单安装一个。下面开始我们的安装表演。

• 检查系统信息

输入"cat /proc/version",说明正在运行的内核版本[root@localhost tomcat]# cat /proc/versionLinux version 2.6.32-431.el6.x86_64 ([e-mail]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-4) (GCC) ) #1 SMP Fri Nov 22 03:15:09 UTC 2013输入"cat /etc/issue", 显示的是发行版本信息[root@localhost tomcat]# cat /etc/issueCentOS release 6.5 (Final)Kernel \r on an \m

• 确定是centos 6.5 的64位系统

安装JDK

• 在JDK官网下载tag.gz文件(http://www.oracle.com/technetwork/java/javase/downloads/index.html)
• 将下载的jdk-8u144-linux-x64.tar.gz文件拷贝到 /opt/jdk 下
• 进入/opt/jdk目录下解压安装文件

 [root@localhost ~]# cd /opt/jdk [root@localhost jdk]# tar -zxvf jdk-7u67-linux-x64.tar.gz # 解压完成后在jdk目录中会有新文件夹jdk1.8.0_144

• 配置全局环境变量，在profile文件中添加jdk路径，等同windows中加全局变量

[root@localhost jdk]# vi /etc/profile  # 在文件末尾添加以下内容# jdk8 settingsJAVA_HOME=/opt/jdk/jdk1.8.0_144JRE_HOME=$JAVA_HOME/jrePATH=$PATH:$JAVA_HOME/bin:$JRE_HOME/binCLASSPATH=:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar:$JRE_HOME/libexport JAVA_HOME JRE_HOME PATH CLASSPATH[root@localhost jdk]# source /etc/profile  #使配置生效

• 建立软连接

[root@localhost jdk]# ln -s /opt/jdk/jdk1.8.0_144/bin/java /sbin/java[root@localhost jdk]# java -version   # 测试安装效果java version "1.8.0_144"Java(TM) SE Runtime Environment (build 1.8.0_144-b01)Java HotSpot(TM) 64-Bit Server VM (build 25.144-b01, mixed mode)

• SUN JDK 安装完成

安装Tomcat

• 下载tomcat(http://apache.fayea.com/tomcat/tomcat-8/v8.0.46/bin/) apache-tomcat-8.0.46.tar.gz
• 将文件拷贝到 /opt/tomcat 目录下
• 解压安装tomcat

[root@localhost opt]# cd tomcat/[root@localhost tomcat]# tar -zxvf apache-tomcat-8.0.46.tar.gz#解压完成，opt下会有apache-tomcat-8.0.46文件

• 创建tomcat软连接，可以使用tomcat 替代apache-tomcat-8.0.46路经

[root@localhost tomcat]# ln -s /opt/tomcat/apache-tomcat-8.0.46/ /sbin/tomcat

• 启动Tomcat，并测试

#启动tomcat[root@localhost tomcat]# /opt/tomcat/apache-tomcat-8.0.46/bin/startup.sh Using CATALINA_BASE:   /opt/tomcat/apache-tomcat-8.0.46Using CATALINA_HOME:   /opt/tomcat/apache-tomcat-8.0.46Using CATALINA_TMPDIR: /opt/tomcat/apache-tomcat-8.0.46/tempUsing JRE_HOME:        /opt/jdk/jdk1.8.0_144/jreUsing CLASSPATH:       /opt/tomcat/apache-tomcat-8.0.46/bin/bootstrap.jar:/opt/tomcat/apache-tomcat-8.0.46/bin/tomcat-juli.jarTomcat started.#查看日志[root@localhost tomcat]# tail -f /opt/tomcat/apache-tomcat-8.0.46/logs/catalina.out #关闭tomcat[root@localhost tomcat]# /opt/tomcat/apache-tomcat-8.0.46/bin/shutdown.sh Using CATALINA_BASE:   /opt/tomcat/apache-tomcat-8.0.46Using CATALINA_HOME:   /opt/tomcat/apache-tomcat-8.0.46Using CATALINA_TMPDIR: /opt/tomcat/apache-tomcat-8.0.46/tempUsing JRE_HOME:        /opt/jdk/jdk1.8.0_144/jreUsing CLASSPATH:       /opt/tomcat/apache-tomcat-8.0.46/bin/bootstrap.jar:/opt/tomcat/apache-tomcat-8.0.46/bin/tomcat-juli.jar
