Linux下安装java1.8和tomcat 8

以前，我一直都是使用Windows server 2008 作为java的应用部署环境来使用，但是貌似主流的软件公司都是使用linux，这对我来说，是一个硬伤啊。

正好，现在公司现在有个项目，自主选择的余地比较大，在使用操作环境上，队友强烈建议使用linux，并吧嗒吧嗒的说了一堆linux的好处，好吧，那就用linux吧，虽然我之前不会，但是我也有强烈的信心，把环境搭好，于是我就真的搭建好了，现在把整个过程分享出来，包含：jdk 1.8的安装和tomcat 8.0的安装

 首先使用工具，把jdk和tomcat上传到服务器

 

然后到linux的黑窗口

输入：javac –version 查看服务器上，当前默认的jdk 版本

 

[root@sxora01 ~]# java -version
java version "1.7.0_45"
OpenJDK Runtime Environment (rhel-2.4.3.3.el6-x86_64 u45-b15)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)

 再输入：rpm -qa|grep java

 

 

 

[root@sxora01 ~]# rpm -qa|grep java
java-1.6.0-openjdk-devel-1.6.0.0-1.66.1.13.0.el6.x86_64
java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64
tzdata-java-2013g-1.el6.noarch
java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64
libvirt-java-devel-0.4.9-1.el6.noarch
java-1.7.0-openjdk-devel-1.7.0.45-2.4.3.3.el6.x86_64
libvirt-java-0.4.9-1.el6.noarch
[root@sxora01 ~]# 

 这个时候，我们可以看到linux 默认java 版本，但是现在我们想使用jdk 1.8 那么我们就要去卸载默认的版本

 

 

卸载以上三个文件（需要root权限，登录root权限卸载）

rpm -e --nodeps java-1.7.0-openjdk-1.7.0.45-2.4.3.3.el6.x86_64

rpm -e --nodeps java-1.6.0-openjdk-1.6.0.0-1.66.1.13.0.el6.x86_64

rpm -e --nodeps tzdata-java-2013g-1.el6.noarch

 

完毕后，再执行 java -version

如果黑窗口出现，没有那个文件或目录的提示那就说明是卸载完毕了，如果没有则

输入：rpm -qa|grep java

输入：rpm -e --nodeps java XXX 把剩余的版本卸载完成

如果上面的步骤执行完毕，那么进入到下一步

 

 

[root@sxweb ~]# cd /usr
[root@sxweb usr]# mkdir java

 

 

在 usr 目录下创建java 文件夹

 

然后在 mv jdk-8u111-linux-x64.tar.gz /usr/java

将压缩包移入到指定的目录

tar -xvzf jdk-8u111-linux-x64.tar.gz

将文件进行解压

然后进行环境配置

 

[root@sxweb java]# vi ~/.bashrc

 出现后，键盘单击  a 进入编辑模式

# User specific aliases and functions

alias rm='rm -i'
alias cp='cp -i'
alias mv='mv -i'

# Source global definitions
if [ -f /etc/bashrc ]; then
        . /etc/bashrc
fi

export JAVA_HOME=/usr/java/jdk1.8.0_111
export JAVA_BIN=$JAVA_HOME/bin
export JAVA_LIB=$JAVA_HOME/lib
export CLASSPATH=.:$JAVA_LIB/tools.jar:$JAVA_LIB/dt.jar
export PATH=$JAVA_BIN:$PATH

 编辑完成  按esc 退出编辑

在输入：wq 关闭并退出

 

 

 

使jdk环境变量生效，source ~/.bashrc

 

[root@sxweb java]# java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
[root@sxweb java]# 

  再次输入 java -version

 则可以看见，环境搭建成功

 

现在，我们再来安装tomcat

cd /usr 进入 usr 目录

mkdir tomcat 创建tomcat 文件夹

mv apache-tomcat-8.0.39.tar.gz  /usr/tomcat 将tomcat 包移动到tomcat里面

tar -xvzf apache-tomcat-8.0.39.tar.gz 进行解压

[root@sxweb tomcat]# mv apache-tomcat-8.0.39/* /usr/tomcat
[root@sxweb tomcat]# ll
total 9204
drwxr-xr-x 2 root root    4096 Jan  5 10:24 apache-tomcat-8.0.39

[root@sxweb tomcat]# cd apache-tomcat-8.0.39
[root@sxweb apache-tomcat-8.0.39]# ll
total 0

 

执行后，在将解压文件夹内容移出到tomcat 目录下

删除空文件夹

[root@sxweb tomcat]# rm -rf apache-tomcat-8.0.39

 cp /usr/tomcat/bin/catalina.sh /etc/init.d/tomcat

 将catalina.sh 复制成/etc/init.d/tomcat

在对该文件进行编辑

[root@sxweb ~]# cd /etc/init.d
[root@sxweb init.d]# ll
