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 total 404 -rwxr-xr-x. 1 root root 1288 Nov 23 2013 abrt-ccpp -rwxr-xr-x. 1 root root 1628 Nov 23 2013 abrtd -rwxr-xr-x. 1 root root 1642 Nov 23 2013 abrt-oops -rwxr-xr-x. 1 root root 1725 Aug 19 2010 acpid -rwxr-xr-x. 1 root root 2062 Jan 30 2012 atd -rwxr-xr-x. 1 root root 3378 Jun 22 2012 auditd -rwxr-xr-x. 1 root root 4043 Nov 23 2013 autofs -r-xr-xr-x. 1 root root 1340 Nov 24 2013 blk-availability -rwxr-xr-x. 1 root root 710 Nov 11 2010 bluetooth -rwxr-xr-x. 1 root root 2094 Feb 22 2013 certmonger -rwxr-xr-x. 1 root root 5160 Nov 23 2013 cgconfig -rwxr-xr-x. 1 root root 3580 Nov 23 2013 cgred -rwxr-xr-x. 1 root root 11355 Aug 13 2013 cpuspeed -rwxr-xr-x. 1 root root 2826 Nov 23 2013 crond -rwxr-xr-x. 1 root root 3034 Aug 17 2013 cups -rwxr-xr-x. 1 root root 1702 Feb 22 2013 dnsmasq -rwxr-xr-x. 1 root root 3245 Jul 9 2013 firstboot -rw-r--r--. 1 root root 18586 Oct 10 2013 functions -rwxr-xr-x. 1 root root 1801 Jul 20 2011 haldaemon -rwxr-xr-x. 1 root root 5866 Oct 10 2013 halt -rwxr-xr-x. 1 root root 2001 Aug 14 2013 htcacheclean -rwxr-xr-x. 1 root root 3371 Aug 14 2013 httpd -rwxr-xr-x. 1 root root 10804 Nov 23 2013 ip6tables -rwxr-xr-x. 1 root root 10688 Nov 23 2013 iptables -rwxr-xr-x. 1 root root 1938 Aug 23 2013 irqbalance -rwxr-xr-x. 1 root root 18133 Nov 23 2013 kdump -rwxr-xr-x. 1 root root 652 Oct 10 2013 killall -rwxr-xr-x. 1 root root 15432 Nov 23 2013 libvirt-guests -r-xr-xr-x. 1 root root 2134 Nov 24 2013 lvm2-lvmetad -r-xr-xr-x. 1 root root 2665 Nov 24 2013 lvm2-monitor -rwxr-xr-x. 1 root root 2571 Oct 11 2013 mdmonitor -rwxr-xr-x. 1 root root 2200 Sep 14 2012 messagebus -rwxr-xr-x. 1 root root 2989 Oct 10 2013 netconsole -rwxr-xr-x. 1 root root 5428 Oct 10 2013 netfs -rwxr-xr-x. 1 root root 6334 Oct 10 2013 network -rwxr-xr-x. 1 root root 2205 Nov 23 2013 NetworkManager -rwxr-xr-x. 1 root root 6364 Nov 22 2013 nfs -rwxr-xr-x. 1 root root 3526 Nov 22 2013 nfslock -rwxr-xr-x. 1 root root 1923 Jul 15 2013 ntpd -rwxr-xr-x. 1 root root 2043 Jul 15 2013 ntpdate -rwxr-xr-x. 1 root root 1875 Oct 15 2012 numad -rwxr-xr-x. 1 root root 2261 Jun 25 2011 oddjobd -rwxr-xr-x. 1 root root 2023 Apr 3 2012 portreserve -rwxr-xr-x. 1 root root 3852 Dec 3 2011 postfix -rwxr-xr-x. 1 root root 1556 Jul 17 2012 psacct -rwxr-xr-x. 1 root root 2034 Jun 13 2013 quota_nld -rwxr-xr-x. 1 root root 1513 Sep 17 2013 rdisc -rwxr-xr-x. 1 root root 1822 Nov 23 2013 restorecond -rwxr-xr-x. 1 root root 1808 Dec 18 2011 rngd -rwxr-xr-x. 1 root root 2073 Feb 22 2013 rpcbind -rwxr-xr-x. 1 root root 2518 Nov 22 2013 rpcgssd -rwxr-xr-x. 1 root root 2305 Nov 22 2013 rpcidmapd -rwxr-xr-x. 1 root root 2464 Nov 22 2013 rpcsvcgssd -rwxr-xr-x. 1 root root 2011 Aug 15 2013 rsyslog -rwxr-xr-x. 1 root root 1698 Nov 23 2013 sandbox -rwxr-xr-x. 1 root root 2056 Nov 20 2012 saslauthd -rwxr-xr-x. 1 root root 647 Oct 10 2013 single -rwxr-xr-x. 1 root root 3002 Feb 22 2013 smartd -rwxr-xr-x. 1 root root 2162 Nov 22 2013 snmpd -rwxr-xr-x. 1 root root 1738 Nov 22 2013 snmptrapd -rwxr-xr-x. 1 root root 2472 Nov 23 2013 spice-vdagentd -rwxr-xr-x. 1 root root 4534 Nov 23 2013 sshd -rwxr-xr-x. 1 root root 2712 Nov 23 2013 sssd -rwxr-xr-x. 1 root root 2276 Apr 2 2013 svnserve -rwxr-xr-x. 1 root root 1144 Nov 23 2013 sysstat -rwxr-xr-x 1 root root 22616 Jan 5 10:48 tomcat -rwxr-xr-x. 1 root root 2294 Nov 23 2013 udev-post -rwxr-xr-x. 1 root root 1674 Feb 22 2013 wdaemon -rwxr-xr-x. 1 root root 1608 Nov 23 2013 winbind -rwxr-xr-x. 1 root root 1866 Feb 4 2013 wpa_supplicant -rwxr-xr-x. 1 root root 3555 Oct 8 2013 xinetd -rwxr-xr-x. 1 root root 4799 Feb 22 2013 ypbind [root@sxweb init.d]# vim tomcat
在文件中加入，我下段全部内容

注释掉的也要加上，不要漏掉
完整:
